<title>Using uio_pdrv for platform devices</title>
<para>
In many cases, UIO drivers for platform devices can be handled in a
generic way. In the same place where you define your
<varname>struct platform_device</varname>, you simply also implement
your interrupt handler and fill your
<varname>struct uio_info</varname>. A pointer to this
<varname>struct uio_info</varname> is then used as
<varname>platform_data</varname> for your platform device.
</para>
<para>
You also need to set up an array of <varname>struct resource</varname>
containing addresses and sizes of your memory mappings. This
information is passed to the driver using the
<varname>.resource</varname> and <varname>.num_resources</varname>
elements of <varname>struct platform_device</varname>.
</para>
<para>
You now have to set the <varname>.name</varname> element of
<varname>struct platform_device</varname> to
<varname>"uio_pdrv"</varname> to use the generic UIO platform device
driver. This driver will fill the <varname>mem[]</varname> array
according to the resources given, and register the device.
</para>

The advantage of this approach is that you only have to edit a file
you need to edit anyway. You do not have to create an extra driver.

<title>Using uio_pdrv_genirq for platform devices</title>
<para>
Especially in embedded devices, you frequently find chips where the
irq pin is tied to its own dedicated interrupt line. In such cases,
where you can be really sure the interrupt is not shared, we can take
the concept of <varname>uio_pdrv</varname> one step further and use a
generic interrupt handler. That's what
<varname>uio_pdrv_genirq</varname> does.
</para>
<para>
The setup for this driver is the same as described above for
<varname>uio_pdrv</varname>, except that you do not implement an
interrupt handler. The <varname>.handler</varname> element of
<varname>struct uio_info</varname> must remain
<varname>NULL</varname>. The <varname>.irq_flags</varname> element
must not contain <varname>IRQF_SHARED</varname>.
</para>
<para>
You will set the <varname>.name</varname> element of
<varname>struct platform_device</varname> to
<varname>"uio_pdrv_genirq"</varname> to use this driver.
</para>
<para>
The generic interrupt handler of <varname>uio_pdrv_genirq</varname>
will simply disable the interrupt line using
<function>disable_irq_nosync()</function>. After doing its work,
userspace can reenable the interrupt by writing 0x00000001 to the UIO
device file. The driver already implements an
<function>irq_control()</function> to make this possible, you must not
implement your own.
</para>
<para>
Using <varname>uio_pdrv_genirq</varname> not only saves a few lines of
interrupt handler code. You also do not need to know anything about
the chip's internal registers to create the kernel part of the driver.
All you need to know is the irq number of the pin the chip is
connected to.

Queue sysfs files
=================
This text file will detail the queue files that are located in the sysfs tree
for each block device. Note that stacked devices typically do not export
any settings, since their queue merely functions are a remapping target.
These files are the ones found in the /sys/block/xxx/queue/ directory.
Files denoted with a RO postfix are readonly and the RW postfix means
read-write.
hw_sector_size (RO)
-------------------
This is the hardware sector size of the device, in bytes.
max_hw_sectors_kb (RO)
----------------------
This is the maximum number of kilobytes supported in a single data transfer.
max_sectors_kb (RW)
-------------------
This is the maximum number of kilobytes that the block layer will allow
for a filesystem request. Must be smaller than or equal to the maximum
size allowed by the hardware.
nomerges (RW)
-------------
This enables the user to disable the lookup logic involved with IO merging
requests in the block layer. Merging may still occur through a direct
1-hit cache, since that comes for (almost) free. The IO scheduler will not
waste cycles doing tree/hash lookups for merges if nomerges is 1. Defaults
to 0, enabling all merges.
nr_requests (RW)
----------------
This controls how many requests may be allocated in the block layer for
read or write requests. Note that the total allocated number may be twice
this amount, since it applies only to reads or writes (not the accumulated
sum).
read_ahead_kb (RW)
------------------
Maximum number of kilobytes to read-ahead for filesystems on this block
device.
rq_affinity (RW)
----------------
If this option is enabled, the block layer will migrate request completions
to the CPU that originally submitted the request. For some workloads
this provides a significant reduction in CPU cycles due to caching effects.
scheduler (RW)
--------------
When read, this file will display the current and available IO schedulers
for this block device. The currently active IO scheduler will be enclosed
in [] brackets. Writing an IO scheduler name to this file will switch
control of this block device to that new IO scheduler. Note that writing
an IO scheduler name to this file will attempt to load that IO scheduler
module, if it isn't already present in the system.

values are in the range -16 to +15, plus the special value -17, which disables
oom-killing altogether for this process.
The process to be killed in an out-of-memory situation is selected among all others
based on its badness score. This value equals the original memory size of the process
and is then updated according to its CPU time (utime + stime) and the
run time (uptime - start time). The longer it runs the smaller is the score.
Badness score is divided by the square root of the CPU time and then by
the double square root of the run time.
Swapped out tasks are killed first. Half of each child's memory size is added to
the parent's score if they do not share the same memory. Thus forking servers
are the prime candidates to be killed. Having only one 'hungry' child will make
parent less preferable than the child.
/proc/<pid>/oom_score shows process' current badness score.
The following heuristics are then applied:
* if the task was reniced, its score doubles
* superuser or direct hardware access tasks (CAP_SYS_ADMIN, CAP_SYS_RESOURCE
or CAP_SYS_RAWIO) have their score divided by 4
* if oom condition happened in one cpuset and checked task does not belong
to it, its score is divided by 8
* the resulting score is multiplied by two to the power of oom_adj, i.e.
points <<= oom_adj when it is positive and
points >>= -(oom_adj) otherwise
The task with the highest badness score is then selected and its children
are killed, process itself will be killed in an OOM situation when it does
not have children or some of them disabled oom like described above.

MPC5200 Device Tree Bindings
----------------------------
(c) 2006-2009 Secret Lab Technologies Ltd
Grant Likely <grant.likely@secretlab.ca>
Naming conventions
------------------
For mpc5200 on-chip devices, the format for each compatible value is
<chip>-<device>[-<mode>]. The OS should be able to match a device driver
to the device based solely on the compatible value. If two drivers
match on the compatible list; the 'most compatible' driver should be
selected.
The split between the MPC5200 and the MPC5200B leaves a bit of a
conundrum. How should the compatible property be set up to provide
maximum compatibility information; but still accurately describe the
chip? For the MPC5200; the answer is easy. Most of the SoC devices
originally appeared on the MPC5200. Since they didn't exist anywhere
else; the 5200 compatible properties will contain only one item;
"fsl,mpc5200-<device>".
The 5200B is almost the same as the 5200, but not quite. It fixes
silicon bugs and it adds a small number of enhancements. Most of the
devices either provide exactly the same interface as on the 5200. A few
devices have extra functions but still have a backwards compatible mode.
To express this information as completely as possible, 5200B device trees
should have two items in the compatible list:
compatible = "fsl,mpc5200b-<device>","fsl,mpc5200-<device>";
It is *strongly* recommended that 5200B device trees follow this convention
(instead of only listing the base mpc5200 item).
ie. ethernet on mpc5200: compatible = "fsl,mpc5200-fec";
ethernet on mpc5200b: compatible = "fsl,mpc5200b-fec", "fsl,mpc5200-fec";
Modal devices, like PSCs, also append the configured function to the
end of the compatible field. ie. A PSC in i2s mode would specify
"fsl,mpc5200-psc-i2s", not "fsl,mpc5200-i2s". This convention is chosen to
avoid naming conflicts with non-psc devices providing the same
function. For example, "fsl,mpc5200-spi" and "fsl,mpc5200-psc-spi" describe
the mpc5200 simple spi device and a PSC spi mode respectively.
At the time of writing, exact chip may be either 'fsl,mpc5200' or
'fsl,mpc5200b'.
The soc node

This node describes the on chip SOC peripherals. Every mpc5200 based
board will have this node, and as such there is a common naming
convention for SOC devices.

fsl,mpc5200-gpt nodes
---------------------
On the mpc5200 and 5200b, GPT0 has a watchdog timer function. If the board
design supports the internal wdt, then the device node for GPT0 should
include the empty property 'fsl,has-wdt'.
An mpc5200-gpt can be used as a single line GPIO controller. To do so,
add the following properties to the gpt node:
gpio-controller;
#gpio-cells = <2>;
When referencing the GPIO line from another node, the first cell must always
be zero and the second cell represents the gpio flags and described in the
gpio device tree binding.
An mpc5200-gpt can be used as a single line edge sensitive interrupt
controller. To do so, add the following properties to the gpt node:
interrupt-controller;
#interrupt-cells = <1>;
When referencing the IRQ line from another node, the cell represents the
sense mode; 1 for edge rising, 2 for edge falling.
fsl,mpc5200-psc nodes
---------------------
The PSCs should include a cell-index which is the index of the PSC in
hardware. cell-index is used to determine which shared SoC registers to
use when setting up PSC clocking. cell-index number starts at '0'. ie:
PSC1 has 'cell-index = <0>'
PSC4 has 'cell-index = <3>'
PSC in i2s mode: The mpc5200 and mpc5200b PSCs are not compatible when in
i2s mode. An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the
compatible field.
fsl,mpc5200-gpio and fsl,mpc5200-gpio-wkup nodes
------------------------------------------------
Each GPIO controller node should have the empty property gpio-controller and
#gpio-cells set to 2. First cell is the GPIO number which is interpreted
according to the bit numbers in the GPIO control registers. The second cell
is for flags which is currently unused.
fsl,mpc5200-fec nodes
---------------------
The FEC node can specify one of the following properties to configure
the MII link:
- fsl,7-wire-mode - An empty property that specifies the link uses 7-wire
mode instead of MII
- current-speed - Specifies that the MII should be configured for a fixed
speed. This property should contain two cells. The
first cell specifies the speed in Mbps and the second
should be '0' for half duplex and '1' for full duplex
- phy-handle - Contains a phandle to an Ethernet PHY.
Interrupt controller (fsl,mpc5200-pic) node
-------------------------------------------
The mpc5200 pic binding splits hardware IRQ numbers into two levels. The
split reflects the layout of the PIC hardware itself, which groups
interrupts into one of three groups; CRIT, MAIN or PERP. Also, the
Bestcomm dma engine has it's own set of interrupt sources which are
cascaded off of peripheral interrupt 0, which the driver interprets as a
fourth group, SDMA.
The interrupts property for device nodes using the mpc5200 pic consists
of three cells; <L1 L2 level>
L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
L2 := interrupt number; directly mapped from the value in the
"ICTL PerStat, MainStat, CritStat Encoded Register"
level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]
For external IRQs, use the following interrupt property values (how to
specify external interrupts is a frequently asked question):
External interrupts:
external irq0: interrupts = <0 0 n>;
external irq1: interrupts = <1 1 n>;
external irq2: interrupts = <1 2 n>;
external irq3: interrupts = <1 3 n>;
'n' is sense (0: level high, 1: edge rising, 2: edge falling 3: level low)

MPC5200 Device Tree Bindings
----------------------------
(c) 2006-2007 Secret Lab Technologies Ltd
Grant Likely <grant.likely at secretlab.ca>
********** DRAFT ***********
* WARNING: Do not depend on the stability of these bindings just yet.
* The MPC5200 device tree conventions are still in flux
* Keep an eye on the linuxppc-dev mailing list for more details
********** DRAFT ***********
I - Introduction
================
Boards supported by the arch/powerpc architecture require device tree be
passed by the boot loader to the kernel at boot time. The device tree
describes what devices are present on the board and how they are
connected. The device tree can either be passed as a binary blob (as
described in Documentation/powerpc/booting-without-of.txt), or passed
by Open Firmware (IEEE 1275) compatible firmware using an OF compatible
client interface API.
This document specifies the requirements on the device-tree for mpc5200
based boards. These requirements are above and beyond the details
specified in either the Open Firmware spec or booting-without-of.txt
All new mpc5200-based boards are expected to match this document. In
cases where this document is not sufficient to support a new board port,
this document should be updated as part of adding the new board support.
II - Philosophy
===============
The core of this document is naming convention. The whole point of
defining this convention is to reduce or eliminate the number of
special cases required to support a 5200 board. If all 5200 boards
follow the same convention, then generic 5200 support code will work
rather than coding special cases for each new board.
This section tries to capture the thought process behind why the naming
convention is what it is.
1. names
---------
There is strong convention/requirements already established for children
of the root node. 'cpus' describes the processor cores, 'memory'
describes memory, and 'chosen' provides boot configuration. Other nodes
are added to describe devices attached to the processor local bus.
Following convention already established with other system-on-chip
processors, 5200 device trees should use the name 'soc5200' for the
parent node of on chip devices, and the root node should be its parent.
Child nodes are typically named after the configured function. ie.
the FEC node is named 'ethernet', and a PSC in uart mode is named 'serial'.
2. device_type property
-----------------------
similar to the node name convention above; the device_type reflects the
configured function of a device. ie. 'serial' for a uart and 'spi' for
an spi controller. However, while node names *should* reflect the
configured function, device_type *must* match the configured function
exactly.
3. compatible property
----------------------
Since device_type isn't enough to match devices to drivers, there also
needs to be a naming convention for the compatible property. Compatible
is an list of device descriptions sorted from specific to generic. For
the mpc5200, the required format for each compatible value is
<chip>-<device>[-<mode>]. The OS should be able to match a device driver
to the device based solely on the compatible value. If two drivers
match on the compatible list; the 'most compatible' driver should be
selected.
The split between the MPC5200 and the MPC5200B leaves a bit of a
conundrum. How should the compatible property be set up to provide
maximum compatibility information; but still accurately describe the
chip? For the MPC5200; the answer is easy. Most of the SoC devices
originally appeared on the MPC5200. Since they didn't exist anywhere
else; the 5200 compatible properties will contain only one item;
"mpc5200-<device>".
The 5200B is almost the same as the 5200, but not quite. It fixes
silicon bugs and it adds a small number of enhancements. Most of the
devices either provide exactly the same interface as on the 5200. A few
devices have extra functions but still have a backwards compatible mode.
To express this information as completely as possible, 5200B device trees
should have two items in the compatible list;
"mpc5200b-<device>\0mpc5200-<device>". It is *strongly* recommended
that 5200B device trees follow this convention (instead of only listing
the base mpc5200 item).
If another chip appear on the market with one of the mpc5200 SoC
devices, then the compatible list should include mpc5200-<device>.
ie. ethernet on mpc5200: compatible = "mpc5200-ethernet"
ethernet on mpc5200b: compatible = "mpc5200b-ethernet\0mpc5200-ethernet"
Modal devices, like PSCs, also append the configured function to the
end of the compatible field. ie. A PSC in i2s mode would specify
"mpc5200-psc-i2s", not "mpc5200-i2s". This convention is chosen to
avoid naming conflicts with non-psc devices providing the same
function. For example, "mpc5200-spi" and "mpc5200-psc-spi" describe
the mpc5200 simple spi device and a PSC spi mode respectively.
If the soc device is more generic and present on other SOCs, the
compatible property can specify the more generic device type also.
ie. mscan: compatible = "mpc5200-mscan\0fsl,mscan";
At the time of writing, exact chip may be either 'mpc5200' or
'mpc5200b'.
Device drivers should always try to match as generically as possible.
III - Structure
===============
The device tree for an mpc5200 board follows the structure defined in
booting-without-of.txt with the following additional notes:
0) the root node
----------------
Typical root description node; see booting-without-of
1) The cpus node
----------------
The cpus node follows the basic layout described in booting-without-of.
The bus-frequency property holds the XLB bus frequency
The clock-frequency property holds the core frequency
2) The memory node
------------------
Typical memory description node; see booting-without-of.
3) The soc5200 node
-------------------
This node describes the on chip SOC peripherals. Every mpc5200 based
board will have this node, and as such there is a common naming
convention for SOC devices.
Required properties:
name type description
---- ---- -----------
device_type string must be "soc"
ranges int should be <0 baseaddr baseaddr+10000>
reg int must be <baseaddr 10000>
compatible string mpc5200: "mpc5200-soc"
mpc5200b: "mpc5200b-soc\0mpc5200-soc"
system-frequency int Fsystem frequency; source of all
other clocks.
bus-frequency int IPB bus frequency in HZ. Clock rate
used by most of the soc devices.
#interrupt-cells int must be <3>.
Recommended properties:
name type description
---- ---- -----------
model string Exact model of the chip;
ie: model="fsl,mpc5200"
revision string Silicon revision of chip
ie: revision="M08A"
The 'model' and 'revision' properties are *strongly* recommended. Having
them presence acts as a bit of a safety net for working around as yet
undiscovered bugs on one version of silicon. For example, device drivers
can use the model and revision properties to decide if a bug fix should
be turned on.
4) soc5200 child nodes
----------------------
Any on chip SOC devices available to Linux must appear as soc5200 child nodes.
Note: The tables below show the value for the mpc5200. A mpc5200b device
tree should use the "mpc5200b-<device>\0mpc5200-<device> form.

Important child node properties
name type description
---- ---- -----------
cell-index int When multiple devices are present, is the
index of the device in the hardware (ie. There
are 6 PSC on the 5200 numbered PSC1 to PSC6)
PSC1 has 'cell-index = <0>'
PSC4 has 'cell-index = <3>'
5) General Purpose Timer nodes (child of soc5200 node)
On the mpc5200 and 5200b, GPT0 has a watchdog timer function. If the board
design supports the internal wdt, then the device node for GPT0 should
include the empty property 'fsl,has-wdt'.
6) PSC nodes (child of soc5200 node)
PSC nodes can define the optional 'port-number' property to force assignment
order of serial ports. For example, PSC5 might be physically connected to
the port labeled 'COM1' and PSC1 wired to 'COM1'. In this case, PSC5 would
have a "port-number = <0>" property, and PSC1 would have "port-number = <1>".
PSC in i2s mode: The mpc5200 and mpc5200b PSCs are not compatible when in
i2s mode. An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the
compatible field.
7) GPIO controller nodes
Each GPIO controller node should have the empty property gpio-controller and
#gpio-cells set to 2. First cell is the GPIO number which is interpreted
according to the bit numbers in the GPIO control registers. The second cell
is for flags which is currently unsused.
8) FEC nodes
The FEC node can specify one of the following properties to configure
the MII link:
"fsl,7-wire-mode" - An empty property that specifies the link uses 7-wire
mode instead of MII
"current-speed" - Specifies that the MII should be configured for a fixed
speed. This property should contain two cells. The
first cell specifies the speed in Mbps and the second
should be '0' for half duplex and '1' for full duplex
"phy-handle" - Contains a phandle to an Ethernet PHY.
IV - Extra Notes
================
1. Interrupt mapping
--------------------
The mpc5200 pic driver splits hardware IRQ numbers into two levels. The
split reflects the layout of the PIC hardware itself, which groups
interrupts into one of three groups; CRIT, MAIN or PERP. Also, the
Bestcomm dma engine has it's own set of interrupt sources which are
cascaded off of peripheral interrupt 0, which the driver interprets as a
fourth group, SDMA.
The interrupts property for device nodes using the mpc5200 pic consists
of three cells; <L1 L2 level>
L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
L2 := interrupt number; directly mapped from the value in the
"ICTL PerStat, MainStat, CritStat Encoded Register"
level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]
2. Shared registers
-------------------
Some SoC devices share registers between them. ie. the i2c devices use
a single clock control register, and almost all device are affected by
the port_config register. Devices which need to manipulate shared regs
should look to the parent SoC node. The soc node is responsible
for arbitrating all shared register access.
