Description:
|
||||
|
||||
As a Kconfig option, individual GPIO signals may be accessed from
|
||||
userspace. GPIOs are only made available to userspace by an explicit
|
||||
"export" operation. If a given GPIO is not claimed for use by
|
||||
kernel code, it may be exported by userspace (and unexported later).
|
||||
Kernel code may export it for complete or partial access.
|
||||
|
||||
GPIOs are identified as they are inside the kernel, using integers in
|
||||
the range 0..INT_MAX. See Documentation/gpio.txt for more information.

If you want to use SELinux, chances are you will want

to use the distro-provided policies, or install the

|

http://oss.tresys.com/projects/refpolicy
|

However, if you want to install a dummy policy for
|

testing, you can do using 'mdp' provided under
|
||||
scripts/selinux. Note that this requires the selinux
|

userspace to be installed - in particular you will
|
||||
need checkpolicy to compile a kernel, and setfiles and
|
||||
fixfiles to label the filesystem.
|
||||
|
||||
1. Compile the kernel with selinux enabled.
|
||||
2. Type 'make' to compile mdp.
|
||||
3. Make sure that you are not running with
|
||||
SELinux enabled and a real policy. If
|
||||
you are, reboot with selinux disabled
|
||||
before continuing.
|
||||
4. Run install_policy.sh:
|
||||
cd scripts/selinux
|
||||
sh install_policy.sh
|
||||
|
||||
Step 4 will create a new dummy policy valid for your
|
||||
kernel, with a single selinux user, role, and type.
|
||||
It will compile the policy, will set your SELINUXTYPE to
|
||||
dummy in /etc/selinux/config, install the compiled policy
|
||||
as 'dummy', and relabel your filesystem.

----------
|
||||
|
||||
When a read request expires its deadline, we must move some requests from
|
||||
the sorted io scheduler list to the block device dispatch queue. fifo_batch
|
||||
controls how many requests we move.
|
||||
Requests are grouped into ``batches'' of a particular data direction (read or
|
||||
write) which are serviced in increasing sector order. To limit extra seeking,
|
||||
deadline expiries are only checked between batches. fifo_batch controls the
|
||||
maximum number of requests per batch.
|
||||
|
||||
This parameter tunes the balance between per-request latency and aggregate
|
||||
throughput. When low latency is the primary concern, smaller is better (where
|
||||
a value of 1 yields first-come first-served behaviour). Increasing fifo_batch

generally improves throughput, at the cost of latency variation.

Fiemap Ioctl
|
||||
============
|
||||
|
||||
The fiemap ioctl is an efficient method for userspace to get file
|
||||
extent mappings. Instead of block-by-block mapping (such as bmap), fiemap
|
||||
returns a list of extents.
|
||||
|
||||
|
||||
Request Basics
|
||||
--------------
|
||||
|
||||
A fiemap request is encoded within struct fiemap:
|
||||
|
||||
struct fiemap {
|
||||
__u64 fm_start; /* logical offset (inclusive) at
|
||||
* which to start mapping (in) */
|
||||
__u64 fm_length; /* logical length of mapping which
|
||||
* userspace cares about (in) */
|
||||
__u32 fm_flags; /* FIEMAP_FLAG_* flags for request (in/out) */
|
||||
__u32 fm_mapped_extents; /* number of extents that were
|
||||
* mapped (out) */
|
||||
__u32 fm_extent_count; /* size of fm_extents array (in) */
|
||||
__u32 fm_reserved;
|
||||
struct fiemap_extent fm_extents[0]; /* array of mapped extents (out) */
|
||||
};
|
||||
|
||||
|
||||
fm_start, and fm_length specify the logical range within the file
|
||||
which the process would like mappings for. Extents returned mirror
|
||||
those on disk - that is, the logical offset of the 1st returned extent
|
||||
may start before fm_start, and the range covered by the last returned
|
||||
extent may end after fm_length. All offsets and lengths are in bytes.
|
||||
|
||||
Certain flags to modify the way in which mappings are looked up can be
|
||||
set in fm_flags. If the kernel doesn't understand some particular
|
||||
flags, it will return EBADR and the contents of fm_flags will contain
|
||||
the set of flags which caused the error. If the kernel is compatible
|
||||
with all flags passed, the contents of fm_flags will be unmodified.
|
||||
It is up to userspace to determine whether rejection of a particular
|
||||
flag is fatal to it's operation. This scheme is intended to allow the
|
||||
fiemap interface to grow in the future but without losing
|
||||
compatibility with old software.
|
||||
|
||||
fm_extent_count specifies the number of elements in the fm_extents[] array
|
||||
that can be used to return extents. If fm_extent_count is zero, then the
|
||||
fm_extents[] array is ignored (no extents will be returned), and the
|
||||
fm_mapped_extents count will hold the number of extents needed in
|
||||
fm_extents[] to hold the file's current mapping. Note that there is
|
||||
nothing to prevent the file from changing between calls to FIEMAP.
|
||||
|
||||
The following flags can be set in fm_flags:
|
||||
|
||||
* FIEMAP_FLAG_SYNC
|
||||
If this flag is set, the kernel will sync the file before mapping extents.
|
||||
|
||||
* FIEMAP_FLAG_XATTR
|
||||
If this flag is set, the extents returned will describe the inodes
|
||||
extended attribute lookup tree, instead of it's data tree.
|
||||
|
||||
|
||||
Extent Mapping
|
||||
--------------
|
||||
|
||||
Extent information is returned within the embedded fm_extents array
|
||||
which userspace must allocate along with the fiemap structure. The
|
||||
number of elements in the fiemap_extents[] array should be passed via
|
||||
fm_extent_count. The number of extents mapped by kernel will be
|
||||
returned via fm_mapped_extents. If the number of fiemap_extents
|
||||
allocated is less than would be required to map the requested range,
|
||||
the maximum number of extents that can be mapped in the fm_extent[]
|
||||
array will be returned and fm_mapped_extents will be equal to
|
||||
fm_extent_count. In that case, the last extent in the array will not
|
||||
complete the requested range and will not have the FIEMAP_EXTENT_LAST
|
||||
flag set (see the next section on extent flags).
|
||||
|
||||
Each extent is described by a single fiemap_extent structure as
|
||||
returned in fm_extents.
|
||||
|
||||
struct fiemap_extent {
|
||||
__u64 fe_logical; /* logical offset in bytes for the start of
|
||||
* the extent */
|
||||
__u64 fe_physical; /* physical offset in bytes for the start
|
||||
* of the extent */
|
||||
__u64 fe_length; /* length in bytes for the extent */
|
||||
__u64 fe_reserved64[2];
|
||||
__u32 fe_flags; /* FIEMAP_EXTENT_* flags for this extent */
|
||||
__u32 fe_reserved[3];
|
||||
};
|
||||
|
||||
All offsets and lengths are in bytes and mirror those on disk. It is valid
|
||||
for an extents logical offset to start before the request or it's logical
|
||||
length to extend past the request. Unless FIEMAP_EXTENT_NOT_ALIGNED is
|
||||
returned, fe_logical, fe_physical, and fe_length will be aligned to the
|
||||
block size of the file system. With the exception of extents flagged as
|
||||
FIEMAP_EXTENT_MERGED, adjacent extents will not be merged.
|
||||
|
||||
The fe_flags field contains flags which describe the extent returned.
|
||||
A special flag, FIEMAP_EXTENT_LAST is always set on the last extent in
|
||||
the file so that the process making fiemap calls can determine when no
|
||||
more extents are available, without having to call the ioctl again.
|
||||
|
||||
Some flags are intentionally vague and will always be set in the
|
||||
presence of other more specific flags. This way a program looking for
|
||||
a general property does not have to know all existing and future flags
|
||||
which imply that property.
|
||||
|
||||
For example, if FIEMAP_EXTENT_DATA_INLINE or FIEMAP_EXTENT_DATA_TAIL
|
||||
are set, FIEMAP_EXTENT_NOT_ALIGNED will also be set. A program looking
|
||||
for inline or tail-packed data can key on the specific flag. Software
|
||||
which simply cares not to try operating on non-aligned extents
|
||||
however, can just key on FIEMAP_EXTENT_NOT_ALIGNED, and not have to
|
||||
worry about all present and future flags which might imply unaligned
|
||||
data. Note that the opposite is not true - it would be valid for
|
||||
FIEMAP_EXTENT_NOT_ALIGNED to appear alone.
|
||||
|
||||
* FIEMAP_EXTENT_LAST
|
||||
This is the last extent in the file. A mapping attempt past this
|
||||
extent will return nothing.
|
||||
|
||||
* FIEMAP_EXTENT_UNKNOWN
|
||||
The location of this extent is currently unknown. This may indicate
|
||||
the data is stored on an inaccessible volume or that no storage has
|
||||
been allocated for the file yet.
|
||||
|
||||
* FIEMAP_EXTENT_DELALLOC
|
||||
- This will also set FIEMAP_EXTENT_UNKNOWN.
|
||||
Delayed allocation - while there is data for this extent, it's
|
||||
physical location has not been allocated yet.
|
||||
|
||||
* FIEMAP_EXTENT_ENCODED
|
||||
This extent does not consist of plain filesystem blocks but is
|
||||
encoded (e.g. encrypted or compressed). Reading the data in this
|
||||
extent via I/O to the block device will have undefined results.
|
||||
|
||||
Note that it is *always* undefined to try to update the data
|
||||
in-place by writing to the indicated location without the
|
||||
assistance of the filesystem, or to access the data using the
|
||||
information returned by the FIEMAP interface while the filesystem
|
||||
is mounted. In other words, user applications may only read the
|
||||
extent data via I/O to the block device while the filesystem is
|
||||
unmounted, and then only if the FIEMAP_EXTENT_ENCODED flag is
|
||||
clear; user applications must not try reading or writing to the
|
||||
filesystem via the block device under any other circumstances.
|
||||
|
||||
* FIEMAP_EXTENT_DATA_ENCRYPTED
|
||||
- This will also set FIEMAP_EXTENT_ENCODED
|
||||
The data in this extent has been encrypted by the file system.
|
||||
|
||||
* FIEMAP_EXTENT_NOT_ALIGNED
|
||||
Extent offsets and length are not guaranteed to be block aligned.
|
||||
|
||||
* FIEMAP_EXTENT_DATA_INLINE
|
||||
This will also set FIEMAP_EXTENT_NOT_ALIGNED
|
||||
Data is located within a meta data block.
|
||||
|
||||
* FIEMAP_EXTENT_DATA_TAIL
|
||||
This will also set FIEMAP_EXTENT_NOT_ALIGNED
|
||||
Data is packed into a block with data from other files.
|
||||
|
||||
* FIEMAP_EXTENT_UNWRITTEN
|
||||
Unwritten extent - the extent is allocated but it's data has not been
|
||||
initialized. This indicates the extent's data will be all zero if read
|
||||
through the filesystem but the contents are undefined if read directly from
|
||||
the device.
|
||||
|
||||
* FIEMAP_EXTENT_MERGED
|
||||
This will be set when a file does not support extents, i.e., it uses a block
|
||||
based addressing scheme. Since returning an extent for each block back to
|
||||
userspace would be highly inefficient, the kernel will try to merge most
|
||||
adjacent blocks into 'extents'.
|
||||
|
||||
|
||||
VFS -> File System Implementation
|
||||
---------------------------------
|
||||
|
||||
File systems wishing to support fiemap must implement a ->fiemap callback on
|
||||
their inode_operations structure. The fs ->fiemap call is responsible for
|
||||
defining it's set of supported fiemap flags, and calling a helper function on
|
||||
each discovered extent:
|
||||
|
||||
struct inode_operations {
|
||||
...
|
||||
|
||||
int (*fiemap)(struct inode *, struct fiemap_extent_info *, u64 start,
|
||||
u64 len);
|
||||
|
||||
->fiemap is passed struct fiemap_extent_info which describes the
|
||||
fiemap request:
|
||||
|
||||
struct fiemap_extent_info {
|
||||
unsigned int fi_flags; /* Flags as passed from user */
|
||||
unsigned int fi_extents_mapped; /* Number of mapped extents */
|
||||
unsigned int fi_extents_max; /* Size of fiemap_extent array */
|
||||
struct fiemap_extent *fi_extents_start; /* Start of fiemap_extent array */
|
||||
};
|
||||
|
||||
It is intended that the file system should not need to access any of this
|
||||
structure directly.
|
||||
|
||||
|
||||
Flag checking should be done at the beginning of the ->fiemap callback via the
|
||||
fiemap_check_flags() helper:
|
||||
|
||||
int fiemap_check_flags(struct fiemap_extent_info *fieinfo, u32 fs_flags);
|
||||
|
||||
The struct fieinfo should be passed in as recieved from ioctl_fiemap(). The
|
||||
set of fiemap flags which the fs understands should be passed via fs_flags. If
|
||||
fiemap_check_flags finds invalid user flags, it will place the bad values in
|
||||
fieinfo->fi_flags and return -EBADR. If the file system gets -EBADR, from
|
||||
fiemap_check_flags(), it should immediately exit, returning that error back to
|
||||
ioctl_fiemap().
|
||||
|
||||
|
||||
For each extent in the request range, the file system should call
|
||||
the helper function, fiemap_fill_next_extent():
|
||||
|
||||
int fiemap_fill_next_extent(struct fiemap_extent_info *info, u64 logical,
|
||||
u64 phys, u64 len, u32 flags, u32 dev);
|
||||
|
||||
fiemap_fill_next_extent() will use the passed values to populate the
|
||||
next free extent in the fm_extents array. 'General' extent flags will
|
||||
automatically be set from specific flags on behalf of the calling file
|
||||
system so that the userspace API is not broken.
|
||||
|
||||
fiemap_fill_next_extent() returns 0 on success, and 1 when the
|
||||
user-supplied fm_extents array is full. If an error is encountered
|
||||
while copying the extent to user memory, -EFAULT will be returned.

6.4 The virtual CAN driver (vcan)
|
||||
|

Similar to the network loopback devices, vcan offers a virtual local
|

CAN interface. A full qualified address on CAN consists of
|
||||
|
||||
- a unique CAN Identifier (CAN ID)
|
||||
- the CAN bus this CAN ID is transmitted on (e.g. can0)
|
||||
|
||||
so in common use cases more than one virtual CAN interface is needed.
|
||||
|
||||
The virtual CAN interfaces allow the transmission and reception of CAN
|
||||
frames without real CAN controller hardware. Virtual CAN network
|
||||
devices are usually named 'vcanX', like vcan0 vcan1 vcan2 ...
|
||||
When compiled as a module the virtual CAN driver module is called vcan.ko
|
||||
|
||||
Since Linux Kernel version 2.6.24 the vcan driver supports the Kernel
|
||||
netlink interface to create vcan network devices. The creation and
|
||||
removal of vcan network devices can be managed with the ip(8) tool:
|
||||
|
||||
- Create a virtual CAN network interface:
|
||||
ip link add type vcan
|
||||
|
||||
- Create a virtual CAN network interface with a specific name 'vcan42':

ip link add dev vcan42 type vcan
|

|

- Remove a (virtual CAN) network interface 'vcan42':

Section 2: Qdisc support for multiqueue devices
|
||||
|
||||
-----------------------------------------------
|
||||
|
||||
Currently two qdiscs are optimized for multiqueue devices. The first is the
|
||||
default pfifo_fast qdisc. This qdisc supports one qdisc per hardware queue.
|
||||
A new round-robin qdisc, sch_multiq also supports multiple hardware queues. The
|
||||
qdisc is responsible for classifying the skb's and then directing the skb's to
|
||||
bands and queues based on the value in skb->queue_mapping. Use this field in
|
||||
the base driver to determine which queue to send the skb to.
|
||||
|
||||
sch_multiq has been added for hardware that wishes to avoid head-of-line
|
||||
blocking. It will cycle though the bands and verify that the hardware queue
|
||||
associated with the band is not stopped prior to dequeuing a packet.
|
||||
|
||||
On qdisc load, the number of bands is based on the number of queues on the
|
||||
hardware. Once the association is made, any skb with skb->queue_mapping set,
|
||||
will be queued to the band associated with the hardware queue.
|
||||
|
||||
|
||||
Section 3: Brief howto using MULTIQ for multiqueue devices
|
||||
---------------------------------------------------------------
|
||||
|
||||
The userspace command 'tc,' part of the iproute2 package, is used to configure
|
||||
qdiscs. To add the MULTIQ qdisc to your network device, assuming the device
|
||||
is called eth0, run the following command:
|
||||
|
||||
# tc qdisc add dev eth0 root handle 1: multiq
|
||||
|
||||
The qdisc will allocate the number of bands to equal the number of queues that
|
||||
the device reports, and bring the qdisc online. Assuming eth0 has 4 Tx
|
||||
queues, the band mapping would look like:
|
||||
|
||||
band 0 => queue 0
|
||||
band 1 => queue 1
|
||||
band 2 => queue 2
|
||||
band 3 => queue 3
|
||||
|
||||
Traffic will begin flowing through each queue based on either the simple_tx_hash
|
||||
function or based on netdev->select_queue() if you have it defined.
|
||||
|
||||
The behavior of tc filters remains the same. However a new tc action,
|
||||
skbedit, has been added. Assuming you wanted to route all traffic to a
|
||||
specific host, for example 192.168.0.3, through a specific queue you could use
|
||||
this action and establish a filter such as:
|
||||
|
||||
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 \
|
||||
match ip dst 192.168.0.3 \
|
||||
action skbedit queue_mapping 3

Linux Phonet protocol family
|
||||
============================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
Phonet is a packet protocol used by Nokia cellular modems for both IPC
|
||||
and RPC. With the Linux Phonet socket family, Linux host processes can
|
||||
receive and send messages from/to the modem, or any other external
|
||||
device attached to the modem. The modem takes care of routing.
|
||||
|
||||
Phonet packets can be exchanged through various hardware connections
|
||||
depending on the device, such as:
|
||||
- USB with the CDC Phonet interface,
|
||||
- infrared,
|
||||
- Bluetooth,
|
||||
- an RS232 serial port (with a dedicated "FBUS" line discipline),
|
||||
- the SSI bus with some TI OMAP processors.
|
||||
|
||||
|
||||
Packets format
|
||||
--------------
|
||||
|
||||
Phonet packets have a common header as follows:
|
||||
|
||||
struct phonethdr {
|
||||
uint8_t pn_media; /* Media type (link-layer identifier) */
|
||||
uint8_t pn_rdev; /* Receiver device ID */
|
||||
uint8_t pn_sdev; /* Sender device ID */
|
||||
uint8_t pn_res; /* Resource ID or function */
|
||||
uint16_t pn_length; /* Big-endian message byte length (minus 6) */
|
||||
uint8_t pn_robj; /* Receiver object ID */
|
||||
uint8_t pn_sobj; /* Sender object ID */
|
||||
};
|
||||
|
||||
On Linux, the link-layer header includes the pn_media byte (see below).
|
||||
The next 7 bytes are part of the network-layer header.
|
||||
|
||||
The device ID is split: the 6 higher-order bits consitute the device
|
||||
address, while the 2 lower-order bits are used for multiplexing, as are
|
||||
the 8-bit object identifiers. As such, Phonet can be considered as a
|
||||
network layer with 6 bits of address space and 10 bits for transport
|
||||
protocol (much like port numbers in IP world).
|
||||
|
||||
The modem always has address number zero. All other device have a their
|
||||
own 6-bit address.
|
||||
|
||||
|
||||
Link layer
|
||||
----------
|
||||
|
||||
Phonet links are always point-to-point links. The link layer header
|
||||
consists of a single Phonet media type byte. It uniquely identifies the
|
||||
link through which the packet is transmitted, from the modem's
|
||||
perspective. Each Phonet network device shall prepend and set the media
|
||||
type byte as appropriate. For convenience, a common phonet_header_ops
|
||||
link-layer header operations structure is provided. It sets the
|
||||
media type according to the network device hardware address.
|
||||
|
||||
Linux Phonet network interfaces support a dedicated link layer packets
|
||||
type (ETH_P_PHONET) which is out of the Ethernet type range. They can
|
||||
only send and receive Phonet packets.
|
||||
|
||||
The virtual TUN tunnel device driver can also be used for Phonet. This
|
||||
requires IFF_TUN mode, _without_ the IFF_NO_PI flag. In this case,
|
||||
there is no link-layer header, so there is no Phonet media type byte.
|
||||
|
||||
Note that Phonet interfaces are not allowed to re-order packets, so
|
||||
only the (default) Linux FIFO qdisc should be used with them.
|
||||
|
||||
|
||||
Network layer
|
||||
-------------
|
||||
|
||||
The Phonet socket address family maps the Phonet packet header:
|
||||
|
||||
struct sockaddr_pn {
|
||||
sa_family_t spn_family; /* AF_PHONET */
|
||||
uint8_t spn_obj; /* Object ID */
|
||||
uint8_t spn_dev; /* Device ID */
|
||||
uint8_t spn_resource; /* Resource or function */
|
||||
uint8_t spn_zero[...]; /* Padding */
|
||||
};
|
||||
|
||||
The resource field is only used when sending and receiving;
|
||||
It is ignored by bind() and getsockname().
|
||||
|
||||
|
||||
Low-level datagram protocol
|
||||
---------------------------
|
||||
|
||||
Applications can send Phonet messages using the Phonet datagram socket
|
||||
protocol from the PF_PHONET family. Each socket is bound to one of the
|
||||
2^10 object IDs available, and can send and receive packets with any
|
||||
other peer.
|
||||
|
||||
struct sockaddr_pn addr = { .spn_family = AF_PHONET, };
|
||||
ssize_t len;
|
||||
socklen_t addrlen = sizeof(addr);
|
||||
int fd;
|
||||
|
||||
fd = socket(PF_PHONET, SOCK_DGRAM, 0);
|
||||
bind(fd, (struct sockaddr *)&addr, sizeof(addr));
|
||||
/* ... */
|
||||
|
||||
sendto(fd, msg, msglen, 0, (struct sockaddr *)&addr, sizeof(addr));
|
||||
len = recvfrom(fd, buf, sizeof(buf), 0,
|
||||
(struct sockaddr *)&addr, &addrlen);
|
||||
|
||||
This protocol follows the SOCK_DGRAM connection-less semantics.
|
||||
However, connect() and getpeername() are not supported, as they did
|
||||
not seem useful with Phonet usages (could be added easily).
|
||||
|
||||
|
||||
Phonet Pipe protocol
|
||||
--------------------
|
||||
|
||||
The Phonet Pipe protocol is a simple sequenced packets protocol
|
||||
with end-to-end congestion control. It uses the passive listening
|
||||
socket paradigm. The listening socket is bound to an unique free object
|
||||
ID. Each listening socket can handle up to 255 simultaneous
|
||||
connections, one per accept()'d socket.
|
||||
|
||||
int lfd, cfd;
|
||||
|
||||
lfd = socket(PF_PHONET, SOCK_SEQPACKET, PN_PROTO_PIPE);
|
||||
listen (lfd, INT_MAX);
|
||||
|
||||
/* ... */
|
||||
cfd = accept(lfd, NULL, NULL);
|
||||
for (;;)
|
||||
{
|
||||
char buf[...];
|
||||
ssize_t len = read(cfd, buf, sizeof(buf));
|
||||
|
||||
/* ... */
|
||||
|
||||
write(cfd, msg, msglen);
|
||||
}
|
||||
|
||||
Connections are established between two endpoints by a "third party"
|
||||
application. This means that both endpoints are passive; so connect()
|
||||
is not possible.
|
||||
|
||||
WARNING:
|
||||
When polling a connected pipe socket for writability, there is an
|
||||
intrinsic race condition whereby writability might be lost between the
|
||||
polling and the writing system calls. In this case, the socket will
|
||||
block until write because possible again, unless non-blocking mode
|
||||
becomes enabled.
|
||||
|
||||
|
||||
The pipe protocol provides two socket options at the SOL_PNPIPE level:
|
||||
|
||||
PNPIPE_ENCAP accepts one integer value (int) of:
|
||||
|
||||
PNPIPE_ENCAP_NONE: The socket operates normally (default).
|
||||
|
||||
PNPIPE_ENCAP_IP: The socket is used as a backend for a virtual IP
|
||||
interface. This requires CAP_NET_ADMIN capability. GPRS data
|
||||
support on Nokia modems can use this. Note that the socket cannot
|
||||
be reliably poll()'d or read() from while in this mode.
|
||||
|
||||
PNPIPE_IFINDEX is a read-only integer value. It contains the
|
||||
interface index of the network interface created by PNPIPE_ENCAP,
|
||||
or zero if encapsulation is off.

Linux wireless regulatory documentation
|
||||
---------------------------------------
|
||||
|
||||
This document gives a brief review over how the Linux wireless
|
||||
regulatory infrastructure works.
|
||||
|
||||
More up to date information can be obtained at the project's web page:
|
||||
|
||||
http://wireless.kernel.org/en/developers/Regulatory
|
||||
|
||||
Keeping regulatory domains in userspace
|
||||
---------------------------------------
|
||||
|
||||
Due to the dynamic nature of regulatory domains we keep them
|
||||
in userspace and provide a framework for userspace to upload
|
||||
to the kernel one regulatory domain to be used as the central
|
||||
core regulatory domain all wireless devices should adhere to.
|
||||
|
||||
How to get regulatory domains to the kernel
|
||||
-------------------------------------------
|
||||
|
||||
Userspace gets a regulatory domain in the kernel by having
|
||||
a userspace agent build it and send it via nl80211. Only
|
||||
expected regulatory domains will be respected by the kernel.
|
||||
|
||||
A currently available userspace agent which can accomplish this
|
||||
is CRDA - central regulatory domain agent. Its documented here:
|
||||
|
||||
http://wireless.kernel.org/en/developers/Regulatory/CRDA
|
||||
|
||||
Essentially the kernel will send a udev event when it knows
|
||||
it needs a new regulatory domain. A udev rule can be put in place
|
||||
to trigger crda to send the respective regulatory domain for a
|
||||
specific ISO/IEC 3166 alpha2.
|
||||
|
||||
Below is an example udev rule which can be used:
|
||||
|
||||
# Example file, should be put in /etc/udev/rules.d/regulatory.rules
|
||||
KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda"
|
||||
|
||||
The alpha2 is passed as an environment variable under the variable COUNTRY.
|
||||
|
||||
Who asks for regulatory domains?
|
||||
--------------------------------
|
||||
|
||||
* Users
|
||||
|
||||
Users can use iw:
|
||||
|
||||
http://wireless.kernel.org/en/users/Documentation/iw
|
||||
|
||||
An example:
|
||||
|
||||
# set regulatory domain to "Costa Rica"
|
||||
iw reg set CR
|
||||
|
||||
This will request the kernel to set the regulatory domain to
|
||||
the specificied alpha2. The kernel in turn will then ask userspace
|
||||
to provide a regulatory domain for the alpha2 specified by the user
|
||||
by sending a uevent.
|
||||
|
||||
* Wireless subsystems for Country Information elements
|
||||
|
||||
The kernel will send a uevent to inform userspace a new
|
||||
regulatory domain is required. More on this to be added
|
||||
as its integration is added.
|
||||
|
||||
* Drivers
|
||||
|
||||
If drivers determine they need a specific regulatory domain
|
||||
set they can inform the wireless core using regulatory_hint().
|
||||
They have two options -- they either provide an alpha2 so that
|
||||
crda can provide back a regulatory domain for that country or
|
||||
they can build their own regulatory domain based on internal
|
||||
custom knowledge so the wireless core can respect it.
|
||||
|
||||
*Most* drivers will rely on the first mechanism of providing a
|
||||
regulatory hint with an alpha2. For these drivers there is an additional
|
||||
check that can be used to ensure compliance based on custom EEPROM
|
||||
regulatory data. This additional check can be used by drivers by
|
||||
registering on its struct wiphy a reg_notifier() callback. This notifier
|
||||
is called when the core's regulatory domain has been changed. The driver
|
||||
can use this to review the changes made and also review who made them
|
||||
(driver, user, country IE) and determine what to allow based on its
|
||||
internal EEPROM data. Devices drivers wishing to be capable of world
|
||||
roaming should use this callback. More on world roaming will be
|
||||
added to this document when its support is enabled.
|
||||
|
||||
Device drivers who provide their own built regulatory domain
|
||||
do not need a callback as the channels registered by them are
|
||||
the only ones that will be allowed and therefore *additional*
|
||||
cannels cannot be enabled.
|
||||
|
||||
Example code - drivers hinting an alpha2:
|
||||
------------------------------------------
|
||||
|
||||
This example comes from the zd1211rw device driver. You can start
|
||||
by having a mapping of your device's EEPROM country/regulatory
|
||||
domain value to to a specific alpha2 as follows:
|
||||
|
||||
static struct zd_reg_alpha2_map reg_alpha2_map[] = {
|
||||
{ ZD_REGDOMAIN_FCC, "US" },
|
||||
{ ZD_REGDOMAIN_IC, "CA" },
|
||||
{ ZD_REGDOMAIN_ETSI, "DE" }, /* Generic ETSI, use most restrictive */
|
||||
{ ZD_REGDOMAIN_JAPAN, "JP" },
|
||||
{ ZD_REGDOMAIN_JAPAN_ADD, "JP" },
|
||||
{ ZD_REGDOMAIN_SPAIN, "ES" },
|
||||
{ ZD_REGDOMAIN_FRANCE, "FR" },
|
||||
|
||||
Then you can define a routine to map your read EEPROM value to an alpha2,
|
||||
as follows:
|
||||
|
||||
static int zd_reg2alpha2(u8 regdomain, char *alpha2)
|
||||
{
|
||||
unsigned int i;
|
||||
struct zd_reg_alpha2_map *reg_map;
|
||||
for (i = 0; i < ARRAY_SIZE(reg_alpha2_map); i++) {
|
||||
reg_map = ®_alpha2_map[i];
|
||||
if (regdomain == reg_map->reg) {
|
||||
alpha2[0] = reg_map->alpha2[0];
|
||||
alpha2[1] = reg_map->alpha2[1];
|
||||
return 0;
|
||||
}
|
||||
}
|
||||
return 1;
|
||||
}
|
||||
|
||||
Lastly, you can then hint to the core of your discovered alpha2, if a match
|
||||
was found. You need to do this after you have registered your wiphy. You
|
||||
are expected to do this during initialization.
|
||||
|
||||
r = zd_reg2alpha2(mac->regdomain, alpha2);
|
||||
if (!r)
|
||||
regulatory_hint(hw->wiphy, alpha2, NULL);
|
||||
|
||||
Example code - drivers providing a built in regulatory domain:
|
||||
--------------------------------------------------------------
|
||||
|
||||
If you have regulatory information you can obtain from your
|
||||
driver and you *need* to use this we let you build a regulatory domain
|
||||
structure and pass it to the wireless core. To do this you should
|
||||
kmalloc() a structure big enough to hold your regulatory domain
|
||||
structure and you should then fill it with your data. Finally you simply
|
||||
call regulatory_hint() with the regulatory domain structure in it.
|
||||
|
||||
Bellow is a simple example, with a regulatory domain cached using the stack.
|
||||
Your implementation may vary (read EEPROM cache instead, for example).
|
||||
|
||||
Example cache of some regulatory domain
|
||||
|
||||
struct ieee80211_regdomain mydriver_jp_regdom = {
|
||||
.n_reg_rules = 3,
|
||||
.alpha2 = "JP",
|
||||
//.alpha2 = "99", /* If I have no alpha2 to map it to */
|
||||
.reg_rules = {
|
||||
/* IEEE 802.11b/g, channels 1..14 */
|
||||
REG_RULE(2412-20, 2484+20, 40, 6, 20, 0),
|
||||
/* IEEE 802.11a, channels 34..48 */
|
||||
REG_RULE(5170-20, 5240+20, 40, 6, 20,
|
||||
NL80211_RRF_PASSIVE_SCAN),
|
||||
/* IEEE 802.11a, channels 52..64 */
|
||||
REG_RULE(5260-20, 5320+20, 40, 6, 20,
|
||||
NL80211_RRF_NO_IBSS |
|
||||
NL80211_RRF_DFS),
|
||||
}
|
||||
};
|
||||
|
||||
Then in some part of your code after your wiphy has been registered:
|
||||
|
||||
int r;
|
||||
struct ieee80211_regdomain *rd;
|
||||
int size_of_regd;
|
||||
int num_rules = mydriver_jp_regdom.n_reg_rules;
|
||||
unsigned int i;
|
||||
|
||||
size_of_regd = sizeof(struct ieee80211_regdomain) +
|
||||
(num_rules * sizeof(struct ieee80211_reg_rule));
|
||||
|
||||
rd = kzalloc(size_of_regd, GFP_KERNEL);
|
||||
if (!rd)
|
||||
return -ENOMEM;
|
||||
|
||||
memcpy(rd, &mydriver_jp_regdom, sizeof(struct ieee80211_regdomain));
|
||||
|
||||
for (i=0; i < num_rules; i++) {
|
||||
memcpy(&rd->reg_rules[i], &mydriver_jp_regdom.reg_rules[i],
|
||||
sizeof(struct ieee80211_reg_rule));
|
||||
}
|
||||
r = regulatory_hint(hw->wiphy, NULL, rd);
|
||||
if (r) {
|
||||
kfree(rd);
|
||||
return r;
|
||||
}

Transparent proxy support
|
||||
=========================
|
||||
|
||||
This feature adds Linux 2.2-like transparent proxy support to current kernels.
|
||||
To use it, enable NETFILTER_TPROXY, the socket match and the TPROXY target in
|
||||
your kernel config. You will need policy routing too, so be sure to enable that
|
||||
as well.
|
||||
|
||||
|
||||
1. Making non-local sockets work
|
||||
================================
|
||||
|
||||
The idea is that you identify packets with destination address matching a local
|
||||
socket on your box, set the packet mark to a certain value, and then match on that
|
||||
value using policy routing to have those packets delivered locally:
|
||||
|
||||
# iptables -t mangle -N DIVERT
|
||||
# iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
|
||||
# iptables -t mangle -A DIVERT -j MARK --set-mark 1
|
||||
# iptables -t mangle -A DIVERT -j ACCEPT
|
||||
|
||||
# ip rule add fwmark 1 lookup 100
|
||||
# ip route add local 0.0.0.0/0 dev lo table 100
|
||||
|
||||
Because of certain restrictions in the IPv4 routing output code you'll have to
|
||||
modify your application to allow it to send datagrams _from_ non-local IP
|
||||
addresses. All you have to do is enable the (SOL_IP, IP_TRANSPARENT) socket
|
||||
option before calling bind:
|
||||
|
||||
fd = socket(AF_INET, SOCK_STREAM, 0);
|
||||
/* - 8< -*/
|
||||
int value = 1;
|
||||
setsockopt(fd, SOL_IP, IP_TRANSPARENT, &value, sizeof(value));
|
||||
/* - 8< -*/
|
||||
name.sin_family = AF_INET;
|
||||
name.sin_port = htons(0xCAFE);
|
||||
name.sin_addr.s_addr = htonl(0xDEADBEEF);
|
||||
bind(fd, &name, sizeof(name));
|
||||
|
||||
A trivial patch for netcat is available here:
|
||||
http://people.netfilter.org/hidden/tproxy/netcat-ip_transparent-support.patch
|
||||
|
||||
|
||||
2. Redirecting traffic
|
||||
======================
|
||||
|
||||
Transparent proxying often involves "intercepting" traffic on a router. This is
|
||||
usually done with the iptables REDIRECT target; however, there are serious
|
||||
limitations of that method. One of the major issues is that it actually
|
||||
modifies the packets to change the destination address -- which might not be
|
||||
acceptable in certain situations. (Think of proxying UDP for example: you won't
|
||||
be able to find out the original destination address. Even in case of TCP
|
||||
getting the original destination address is racy.)
|
||||
|
||||
The 'TPROXY' target provides similar functionality without relying on NAT. Simply
|
||||
add rules like this to the iptables ruleset above:
|
||||
|
||||
# iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY \
|
||||
--tproxy-mark 0x1/0x1 --on-port 50080
|
||||
|
||||
Note that for this to work you'll have to modify the proxy to enable (SOL_IP,
|
||||
IP_TRANSPARENT) for the listening socket.
|
||||
|
||||
|
||||
3. Iptables extensions
|
||||
======================
|
||||
|
||||
To use tproxy you'll need to have the 'socket' and 'TPROXY' modules
|
||||
compiled for iptables. A patched version of iptables is available
|
||||
here: http://git.balabit.hu/?p=bazsi/iptables-tproxy.git
|
||||
|
||||

||||

5. During suspend, the rfkill class will attempt to soft-block the radio

cycle.

In other words, there is absolutely no allowed scenario where a driver can

with scenarios where soft-blocking or both soft and hard blocking is happening.
|

Scenarios where hardware rfkill lines are the only ones blocking the

transmitter are outside of this rule, since the wireless device driver does not

This is the CFS scheduler.
|
||||
|
||||
80% of CFS's design can be summed up in a single sentence: CFS basically
|
||||
models an "ideal, precise multi-tasking CPU" on real hardware.
|
||||
|
||||
"Ideal multi-tasking CPU" is a (non-existent :-)) CPU that has 100%
|
||||
physical power and which can run each task at precise equal speed, in
|
||||
parallel, each at 1/nr_running speed. For example: if there are 2 tasks
|
||||
running then it runs each at 50% physical power - totally in parallel.
|
||||
|
||||
On real hardware, we can run only a single task at once, so while that
|
||||
one task runs, the other tasks that are waiting for the CPU are at a
|
||||
disadvantage - the current task gets an unfair amount of CPU time. In
|
||||
CFS this fairness imbalance is expressed and tracked via the per-task
|
||||
p->wait_runtime (nanosec-unit) value. "wait_runtime" is the amount of
|
||||
time the task should now run on the CPU for it to become completely fair
|
||||
and balanced.
|
||||
|
||||
( small detail: on 'ideal' hardware, the p->wait_runtime value would
|
||||
always be zero - no task would ever get 'out of balance' from the
|
||||
'ideal' share of CPU time. )
|
||||
|
||||
CFS's task picking logic is based on this p->wait_runtime value and it
|
||||
is thus very simple: it always tries to run the task with the largest
|
||||
p->wait_runtime value. In other words, CFS tries to run the task with
|
||||
the 'gravest need' for more CPU time. So CFS always tries to split up
|
||||
CPU time between runnable tasks as close to 'ideal multitasking
|
||||
hardware' as possible.
|
||||
|
||||
Most of the rest of CFS's design just falls out of this really simple
|
||||
concept, with a few add-on embellishments like nice levels,
|
||||
multiprocessing and various algorithm variants to recognize sleepers.
|
||||
|
||||
In practice it works like this: the system runs a task a bit, and when
|
||||
the task schedules (or a scheduler tick happens) the task's CPU usage is
|
||||
'accounted for': the (small) time it just spent using the physical CPU
|
||||
is deducted from p->wait_runtime. [minus the 'fair share' it would have
|
||||
gotten anyway]. Once p->wait_runtime gets low enough so that another
|
||||
task becomes the 'leftmost task' of the time-ordered rbtree it maintains
|
||||
(plus a small amount of 'granularity' distance relative to the leftmost
|
||||
task so that we do not over-schedule tasks and trash the cache) then the
|
||||
new leftmost task is picked and the current task is preempted.
|
||||
|
||||
The rq->fair_clock value tracks the 'CPU time a runnable task would have
|
||||
fairly gotten, had it been runnable during that time'. So by using
|
||||
rq->fair_clock values we can accurately timestamp and measure the
|
||||
'expected CPU time' a task should have gotten. All runnable tasks are
|
||||
sorted in the rbtree by the "rq->fair_clock - p->wait_runtime" key, and
|
||||
CFS picks the 'leftmost' task and sticks to it. As the system progresses
|
||||
forwards, newly woken tasks are put into the tree more and more to the
|
||||
right - slowly but surely giving a chance for every task to become the
|
||||
'leftmost task' and thus get on the CPU within a deterministic amount of
|
||||
time.
|
||||
|
||||
Some implementation details:
|
||||
|
||||
- the introduction of Scheduling Classes: an extensible hierarchy of
|
||||
scheduler modules. These modules encapsulate scheduling policy
|
||||
details and are handled by the scheduler core without the core
|
||||
code assuming about them too much.
|
||||
|
||||
- sched_fair.c implements the 'CFS desktop scheduler': it is a
|
||||
replacement for the vanilla scheduler's SCHED_OTHER interactivity
|
||||
code.
|
||||
|
||||
I'd like to give credit to Con Kolivas for the general approach here:
|
||||
he has proven via RSDL/SD that 'fair scheduling' is possible and that
|
||||
it results in better desktop scheduling. Kudos Con!
|
||||
|
||||
The CFS patch uses a completely different approach and implementation
|
||||
from RSDL/SD. My goal was to make CFS's interactivity quality exceed
|
||||
that of RSDL/SD, which is a high standard to meet :-) Testing
|
||||
feedback is welcome to decide this one way or another. [ and, in any
|
||||
case, all of SD's logic could be added via a kernel/sched_sd.c module
|
||||
as well, if Con is interested in such an approach. ]
|
||||
|
||||
CFS's design is quite radical: it does not use runqueues, it uses a
|
||||
time-ordered rbtree to build a 'timeline' of future task execution,
|
||||
and thus has no 'array switch' artifacts (by which both the vanilla
|
||||
scheduler and RSDL/SD are affected).
|
||||
|
||||
CFS uses nanosecond granularity accounting and does not rely on any
|
||||
jiffies or other HZ detail. Thus the CFS scheduler has no notion of
|
||||
'timeslices' and has no heuristics whatsoever. There is only one
|
||||
central tunable (you have to switch on CONFIG_SCHED_DEBUG):
|
||||
|
||||
/proc/sys/kernel/sched_granularity_ns
|
||||
|
||||
which can be used to tune the scheduler from 'desktop' (low
|
||||
latencies) to 'server' (good batching) workloads. It defaults to a
|
||||
setting suitable for desktop workloads. SCHED_BATCH is handled by the
|
||||
CFS scheduler module too.
|
||||
|
||||
Due to its design, the CFS scheduler is not prone to any of the
|
||||
'attacks' that exist today against the heuristics of the stock
|
||||
scheduler: fiftyp.c, thud.c, chew.c, ring-test.c, massive_intr.c all
|
||||
work fine and do not impact interactivity and produce the expected
|
||||
behavior.
|
||||
|
||||
the CFS scheduler has a much stronger handling of nice levels and
|
||||
SCHED_BATCH: both types of workloads should be isolated much more
|
||||
agressively than under the vanilla scheduler.
|
||||
|
||||
( another detail: due to nanosec accounting and timeline sorting,
|
||||
sched_yield() support is very simple under CFS, and in fact under
|
||||
CFS sched_yield() behaves much better than under any other
|
||||
scheduler i have tested so far. )
|
||||
|
||||
- sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler
|
||||
way than the vanilla scheduler does. It uses 100 runqueues (for all
|
||||
100 RT priority levels, instead of 140 in the vanilla scheduler)
|
||||
and it needs no expired array.
|
||||
|
||||
- reworked/sanitized SMP load-balancing: the runqueue-walking
|
||||
assumptions are gone from the load-balancing code now, and
|
||||
iterators of the scheduling modules are used. The balancing code got
|
||||
quite a bit simpler as a result.

Group scheduler extension to CFS

================================

1. OVERVIEW
|
||||
|
||||
Normally the scheduler operates on individual tasks and strives to provide
|
||||
fair CPU time to each task. Sometimes, it may be desirable to group tasks
|
||||
and provide fair CPU time to each such task group. For example, it may
|
||||
be desirable to first provide fair CPU time to each user on the system
|
||||
and then to each task belonging to a user.
|
||||
CFS stands for "Completely Fair Scheduler," and is the new "desktop" process
|
||||
scheduler implemented by Ingo Molnar and merged in Linux 2.6.23. It is the
|
||||
replacement for the previous vanilla scheduler's SCHED_OTHER interactivity
|
||||
code.
|
||||
|
||||
CONFIG_FAIR_GROUP_SCHED strives to achieve exactly that. It lets
|
||||
SCHED_NORMAL/BATCH tasks be be grouped and divides CPU time fairly among such
|
||||
groups. At present, there are two (mutually exclusive) mechanisms to group
|
||||
tasks for CPU bandwidth control purpose:
|
||||
80% of CFS's design can be summed up in a single sentence: CFS basically models
|
||||
an "ideal, precise multi-tasking CPU" on real hardware.
|
||||
|
||||
- Based on user id (CONFIG_FAIR_USER_SCHED)
|
||||
In this option, tasks are grouped according to their user id.
|
||||
- Based on "cgroup" pseudo filesystem (CONFIG_FAIR_CGROUP_SCHED)
|
||||
This options lets the administrator create arbitrary groups
|
||||
of tasks, using the "cgroup" pseudo filesystem. See
|
||||
Documentation/cgroups.txt for more information about this
|
||||
filesystem.
|
||||
"Ideal multi-tasking CPU" is a (non-existent :-)) CPU that has 100% physical
|
||||
power and which can run each task at precise equal speed, in parallel, each at
|
||||
1/nr_running speed. For example: if there are 2 tasks running, then it runs
|
||||
each at 50% physical power --- i.e., actually in parallel.
|
||||
|
||||
On real hardware, we can run only a single task at once, so we have to
|
||||
introduce the concept of "virtual runtime." The virtual runtime of a task
|
||||
specifies when its next timeslice would start execution on the ideal
|
||||
multi-tasking CPU described above. In practice, the virtual runtime of a task
|
||||
is its actual runtime normalized to the total number of running tasks.
|
||||
|
||||
|
||||
|
||||
2. FEW IMPLEMENTATION DETAILS
|
||||
|
||||
In CFS the virtual runtime is expressed and tracked via the per-task
|
||||
p->se.vruntime (nanosec-unit) value. This way, it's possible to accurately
|
||||
timestamp and measure the "expected CPU time" a task should have gotten.
|
||||
|
||||
[ small detail: on "ideal" hardware, at any time all tasks would have the same
|
||||
p->se.vruntime value --- i.e., tasks would execute simultaneously and no task
|
||||
would ever get "out of balance" from the "ideal" share of CPU time. ]
|
||||
|
||||
CFS's task picking logic is based on this p->se.vruntime value and it is thus
|
||||
very simple: it always tries to run the task with the smallest p->se.vruntime
|
||||
value (i.e., the task which executed least so far). CFS always tries to split
|
||||
up CPU time between runnable tasks as close to "ideal multitasking hardware" as
|
||||
possible.
|
||||
|
||||
Most of the rest of CFS's design just falls out of this really simple concept,
|
||||
with a few add-on embellishments like nice levels, multiprocessing and various
|
||||
algorithm variants to recognize sleepers.
|
||||
|
||||
|
||||
|
||||
3. THE RBTREE
|
||||
|
||||
CFS's design is quite radical: it does not use the old data structures for the
|
||||
runqueues, but it uses a time-ordered rbtree to build a "timeline" of future
|
||||
task execution, and thus has no "array switch" artifacts (by which both the
|
||||
previous vanilla scheduler and RSDL/SD are affected).
|
||||
|
||||
CFS also maintains the rq->cfs.min_vruntime value, which is a monotonic
|
||||
increasing value tracking the smallest vruntime among all tasks in the
|
||||
runqueue. The total amount of work done by the system is tracked using
|
||||
min_vruntime; that value is used to place newly activated entities on the left
|
||||
side of the tree as much as possible.
|
||||
|
||||
The total number of running tasks in the runqueue is accounted through the
|
||||
rq->cfs.load value, which is the sum of the weights of the tasks queued on the
|
||||
runqueue.
|
||||
|
||||
CFS maintains a time-ordered rbtree, where all runnable tasks are sorted by the
|
||||
p->se.vruntime key (there is a subtraction using rq->cfs.min_vruntime to
|
||||
account for possible wraparounds). CFS picks the "leftmost" task from this
|
||||
tree and sticks to it.
|
||||
As the system progresses forwards, the executed tasks are put into the tree
|
||||
more and more to the right --- slowly but surely giving a chance for every task
|
||||
to become the "leftmost task" and thus get on the CPU within a deterministic
|
||||
amount of time.
|
||||
|
||||
Summing up, CFS works like this: it runs a task a bit, and when the task
|
||||
schedules (or a scheduler tick happens) the task's CPU usage is "accounted
|
||||
for": the (small) time it just spent using the physical CPU is added to
|
||||
p->se.vruntime. Once p->se.vruntime gets high enough so that another task
|
||||
becomes the "leftmost task" of the time-ordered rbtree it maintains (plus a
|
||||
small amount of "granularity" distance relative to the leftmost task so that we
|
||||
do not over-schedule tasks and trash the cache), then the new leftmost task is
|
||||
picked and the current task is preempted.
|
||||
|
||||
|
||||
|
||||
4. SOME FEATURES OF CFS
|
||||
|
||||
CFS uses nanosecond granularity accounting and does not rely on any jiffies or
|
||||
other HZ detail. Thus the CFS scheduler has no notion of "timeslices" in the
|
||||
way the previous scheduler had, and has no heuristics whatsoever. There is
|
||||
only one central tunable (you have to switch on CONFIG_SCHED_DEBUG):
|
||||
|
||||
/proc/sys/kernel/sched_granularity_ns
|
||||
|
||||
which can be used to tune the scheduler from "desktop" (i.e., low latencies) to
|
||||
"server" (i.e., good batching) workloads. It defaults to a setting suitable
|
||||
for desktop workloads. SCHED_BATCH is handled by the CFS scheduler module too.
|
||||
|
||||
Due to its design, the CFS scheduler is not prone to any of the "attacks" that
|
||||
exist today against the heuristics of the stock scheduler: fiftyp.c, thud.c,
|
||||
chew.c, ring-test.c, massive_intr.c all work fine and do not impact
|
||||
interactivity and produce the expected behavior.
|
||||
|
||||
The CFS scheduler has a much stronger handling of nice levels and SCHED_BATCH
|
||||
than the previous vanilla scheduler: both types of workloads are isolated much
|
||||
more aggressively.
|
||||
|
||||
SMP load-balancing has been reworked/sanitized: the runqueue-walking
|
||||
assumptions are gone from the load-balancing code now, and iterators of the
|
||||
scheduling modules are used. The balancing code got quite a bit simpler as a
|
||||
result.
|
||||
|
||||
|
||||
|
||||
5. Scheduling policies
|
||||
|
||||
CFS implements three scheduling policies:
|
||||
|
||||
- SCHED_NORMAL (traditionally called SCHED_OTHER): The scheduling
|
||||
policy that is used for regular tasks.
|
||||
|
||||
- SCHED_BATCH: Does not preempt nearly as often as regular tasks
|
||||
would, thereby allowing tasks to run longer and make better use of
|
||||
caches but at the cost of interactivity. This is well suited for
|
||||
batch jobs.
|
||||
|
||||
- SCHED_IDLE: This is even weaker than nice 19, but its not a true
|
||||
idle timer scheduler in order to avoid to get into priority
|
||||
inversion problems which would deadlock the machine.
|
||||
|
||||
SCHED_FIFO/_RR are implemented in sched_rt.c and are as specified by
|
||||
POSIX.
|
||||
|
||||
The command chrt from util-linux-ng 2.13.1.1 can set all of these except
|
||||
SCHED_IDLE.
|
||||
|
||||
|
||||
|
||||
6. SCHEDULING CLASSES
|
||||
|
||||
The new CFS scheduler has been designed in such a way to introduce "Scheduling
|
||||
Classes," an extensible hierarchy of scheduler modules. These modules
|
||||
encapsulate scheduling policy details and are handled by the scheduler core
|
||||
without the core code assuming too much about them.
|
||||
|
||||
sched_fair.c implements the CFS scheduler described above.
|
||||
|
||||
sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler way than
|
||||
the previous vanilla scheduler did. It uses 100 runqueues (for all 100 RT
|
||||
priority levels, instead of 140 in the previous scheduler) and it needs no
|
||||
expired array.
|
||||
|
||||
Scheduling classes are implemented through the sched_class structure, which
|
||||
contains hooks to functions that must be called whenever an interesting event
|
||||
occurs.
|
||||
|
||||
This is the (partial) list of the hooks:
|
||||
|
||||
- enqueue_task(...)
|
||||
|
||||
Called when a task enters a runnable state.
|
||||
It puts the scheduling entity (task) into the red-black tree and
|
||||
increments the nr_running variable.
|
||||
|
||||
- dequeue_tree(...)
|
||||
|
||||
When a task is no longer runnable, this function is called to keep the
|
||||
corresponding scheduling entity out of the red-black tree. It decrements
|
||||
the nr_running variable.
|
||||
|
||||
- yield_task(...)
|
||||
|
||||
This function is basically just a dequeue followed by an enqueue, unless the
|
||||
compat_yield sysctl is turned on; in that case, it places the scheduling
|
||||
entity at the right-most end of the red-black tree.
|
||||
|
||||
- check_preempt_curr(...)
|
||||
|
||||
This function checks if a task that entered the runnable state should
|
||||
preempt the currently running task.
|
||||
|
||||
- pick_next_task(...)
|
||||
|
||||
This function chooses the most appropriate task eligible to run next.
|
||||
|
||||
- set_curr_task(...)
|
||||
|
||||
This function is called when a task changes its scheduling class or changes
|
||||
its task group.
|
||||
|
||||
- task_tick(...)
|
||||
|
||||
This function is mostly called from time tick functions; it might lead to
|
||||
process switch. This drives the running preemption.
|
||||
|
||||
- task_new(...)
|
||||
|
||||
The core scheduler gives the scheduling module an opportunity to manage new
|
||||
task startup. The CFS scheduling module uses it for group scheduling, while
|
||||
the scheduling module for a real-time task does not use it.
|
||||
|
||||
|
||||
|
||||
7. GROUP SCHEDULER EXTENSIONS TO CFS
|
||||
|
||||
Normally, the scheduler operates on individual tasks and strives to provide
|
||||
fair CPU time to each task. Sometimes, it may be desirable to group tasks and
|
||||
provide fair CPU time to each such task group. For example, it may be
|
||||
desirable to first provide fair CPU time to each user on the system and then to
|
||||
each task belonging to a user.
|
||||
|
||||
CONFIG_GROUP_SCHED strives to achieve exactly that. It lets tasks to be
|
||||
grouped and divides CPU time fairly among such groups.
|
||||
|
||||
CONFIG_RT_GROUP_SCHED permits to group real-time (i.e., SCHED_FIFO and
|
||||
SCHED_RR) tasks.
|
||||
|
||||
CONFIG_FAIR_GROUP_SCHED permits to group CFS (i.e., SCHED_NORMAL and
|
||||
SCHED_BATCH) tasks.
|
||||
|
||||
At present, there are two (mutually exclusive) mechanisms to group tasks for
|
||||
CPU bandwidth control purposes:
|
||||
|
||||
- Based on user id (CONFIG_USER_SCHED)
|
||||
|
||||
With this option, tasks are grouped according to their user id.
|
||||
|
||||
- Based on "cgroup" pseudo filesystem (CONFIG_CGROUP_SCHED)
|
||||
|
||||
This options needs CONFIG_CGROUPS to be defined, and lets the administrator
|
||||
create arbitrary groups of tasks, using the "cgroup" pseudo filesystem. See
|
||||
Documentation/cgroups.txt for more information about this filesystem.
|
||||
|
||||
Only one of these options to group tasks can be chosen and not both.
|
||||
|
||||
Group scheduler tunables:
|
||||
|
||||
When CONFIG_FAIR_USER_SCHED is defined, a directory is created in sysfs for
|
||||
each new user and a "cpu_share" file is added in that directory.
|
||||
When CONFIG_USER_SCHED is defined, a directory is created in sysfs for each new
|
||||
user and a "cpu_share" file is added in that directory.
