The following is a list of files and features that are going to be
|
|
|
|
removed in the kernel source tree. Every entry should contain what
|
|
|
|
exactly is going away, why it is happening, and who is going to be doing
|
|
|
|
the work. When the feature is removed from the kernel, it should also
|
|
|
|
be removed from this file.

|
|
What: PRISM54
|
|
|
|
When: 2.6.34
|
|
|
|
|
|
|
|
Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the
|
|
|
|
prism54 wireless driver. After Intersil stopped selling these
|
|
|
|
devices in preference for the newer more flexible SoftMAC devices
|
|
|
|
a SoftMAC device driver was required and prism54 did not support
|
|
|
|
them. The p54pci driver now exists and has been present in the kernel for
|
|
|
|
a while. This driver supports both SoftMAC devices and FullMAC devices.
|
|
|
|
The main difference between these devices was the amount of memory which
|
|
|
|
could be used for the firmware. The SoftMAC devices support a smaller
|
|
|
|
amount of memory. Because of this the SoftMAC firmware fits into FullMAC
|
|
|
|
devices's memory. p54pci supports not only PCI / Cardbus but also USB
|
|
|
|
and SPI. Since p54pci supports all devices prism54 supports
|
|
|
|
you will have a conflict. I'm not quite sure how distributions are
|
|
|
|
handling this conflict right now. prism54 was kept around due to
|
|
|
|
claims users may experience issues when using the SoftMAC driver.
|
|
|
|
Time has passed users have not reported issues. If you use prism54
|
|
|
|
and for whatever reason you cannot use p54pci please let us know!

What: IRQF_SAMPLE_RANDOM
|
|
|
|
Check: IRQF_SAMPLE_RANDOM
|
|
|
|
When: July 2009
|
|
|
|
|
|
|
|
Why: Many of IRQF_SAMPLE_RANDOM users are technically bogus as entropy
|
|
|
|
sources in the kernel's current entropy model. To resolve this, every
|
|
|
|
input point to the kernel's entropy pool needs to better document the
|
|
|
|
type of entropy source it actually is. This will be replaced with
|
|
|
|
additional add_*_randomness functions in drivers/char/random.c

What: Deprecated snapshot ioctls
|
|
|
|
When: 2.6.36
|
|
|
|
|
|
|
|
Why: The ioctls in kernel/power/user.c were marked as deprecated long time
|
|
|
|
ago. Now they notify users about that so that they need to replace
|
|
|
|
their userspace. After some more time, remove them completely.

What: The ieee80211_regdom module parameter
|
2009-03-24 19:21:07 -06:00
|
|
|
When: March 2010 / desktop catchup
|
2009-03-20 21:53:06 -06:00
|
|
|
|
|
|
|
Why: This was inherited by the CONFIG_WIRELESS_OLD_REGULATORY code,
|
|
|
|
and currently serves as an option for users to define an
|
|
|
|
ISO / IEC 3166 alpha2 code for the country they are currently
|
|
|
|
present in. Although there are userspace API replacements for this
|
|
|
|
through nl80211 distributions haven't yet caught up with implementing
|
|
|
|
decent alternatives through standard GUIs. Although available as an
|
|
|
|
option through iw or wpa_supplicant its just a matter of time before
|
|
|
|
distributions pick up good GUI options for this. The ideal solution
|
|
|
|
would actually consist of intelligent designs which would do this for
|
|
|
|
the user automatically even when travelling through different countries.
|
|
|
|
Until then we leave this module parameter as a compromise.
|
|
|
|
|
|
|
|
When userspace improves with reasonable widely-available alternatives for
|
|
|
|
this we will no longer need this module parameter. This entry hopes that
|
|
|
|
by the super-futuristically looking date of "March 2010" we will have
|
|
|
|
such replacements widely available.

|
2006-08-30 14:50:27 -06:00
|
|
|
When: July 2007
|
|
|
|
Why: Broken design for runtime control over driver power states, confusing
|
|
|
|
driver-internal runtime power management with: mechanisms to support
|
|
|
|
system-wide sleep state transitions; event codes that distinguish
|
|
|
|
different phases of swsusp "sleep" transitions; and userspace policy
|
|
|
|
inputs. This framework was never widely used, and most attempts to
|
|
|
|
use it were broken. Drivers should instead be exposing domain-specific
|
|
|
|
interfaces either to kernel or to userspace.

Why: V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6
|
2005-11-08 22:38:53 -07:00
|
|
|
series. The old API have lots of drawbacks and don't provide enough
|
|
|
|
means to work with all video and audio standards. The newer API is
|
|
|
|
already available on the main drivers and should be used instead.
|
|
|
|
Newer drivers should use v4l_compat_translate_ioctl function to handle
|
|
|
|
old calls, replacing to newer ones.
|
|
|
|
Decoder iocts are using internally to allow video drivers to
|
|
|
|
communicate with video decoders. This should also be improved to allow
|
|
|
|
V4L2 calls being translated into compatible internal ioctls.
|
2007-10-17 11:32:36 -06:00
|
|
|
Compatibility ioctls will be provided, for a while, via
|
|
|
|
v4l1-compat module.

What: sys_sysctl
|
|
|
|
When: September 2010
|
|
|
|
Option: CONFIG_SYSCTL_SYSCALL
|
|
|
|
Why: The same information is available in a more convenient from
|
|
|
|
/proc/sys, and none of the sysctl variables appear to be
|
|
|
|
important performance wise.
|
|
|
|
|
|
|
|
Binary sysctls are a long standing source of subtle kernel
|
|
|
|
bugs and security issues.
|
|
|
|
|
|
|
|
When I looked several months ago all I could find after
|
|
|
|
searching several distributions were 5 user space programs and
|
|
|
|
glibc (which falls back to /proc/sys) using this syscall.
|
|
|
|
|
|
|
|
The man page for sysctl(2) documents it as unusable for user
|
|
|
|
space programs.
|
|
|
|
|
|
|
|
sysctl(2) is not generally ABI compatible to a 32bit user
|
|
|
|
space application on a 64bit and a 32bit kernel.
|
|
|
|
|
|
|
|
For the last several months the policy has been no new binary
|
|
|
|
sysctls and no one has put forward an argument to use them.
|
|
|
|
|
|
|
|
Binary sysctls issues seem to keep happening appearing so
|
|
|
|
properly deprecating them (with a warning to user space) and a
|
|
|
|
2 year grace warning period will mean eventually we can kill
|
|
|
|
them and end the pain.
|
|
|
|
|
|
|
|
In the mean time individual binary sysctls can be dealt with
|
|
|
|
in a piecewise fashion.

2010-08-09 18:19:47 -06:00
|
|
|
What: /proc/<pid>/oom_adj
|
|
|
|
When: August 2012
|
|
|
|
Why: /proc/<pid>/oom_adj allows userspace to influence the oom killer's
|
|
|
|
badness heuristic used to determine which task to kill when the kernel
|
|
|
|
is out of memory.
|
|
|
|
|
|
|
|
The badness heuristic has since been rewritten since the introduction of
|
|
|
|
this tunable such that its meaning is deprecated. The value was
|
|
|
|
implemented as a bitshift on a score generated by the badness()
|
|
|
|
function that did not have any precise units of measure. With the
|
|
|
|
rewrite, the score is given as a proportion of available memory to the
|
|
|
|
task allocating pages, so using a bitshift which grows the score
|
|
|
|
exponentially is, thus, impossible to tune with fine granularity.
|
|
|
|
|
|
|
|
A much more powerful interface, /proc/<pid>/oom_score_adj, was
|
|
|
|
introduced with the oom killer rewrite that allows users to increase or
|
|
|
|
decrease the badness() score linearly. This interface will replace
|
|
|
|
/proc/<pid>/oom_adj.
|
|
|
|
|
|
|
|
A warning will be emitted to the kernel log if an application uses this
|
|
|
|
deprecated interface. After it is printed once, future warnings will be
|
|
|
|
suppressed until the kernel is rebooted.

|
Check: kernel_thread
|
2006-03-24 04:18:22 -07:00
|
|
|
Why: kernel_thread is a low-level implementation detail. Drivers should
|
|
|
|
use the <linux/kthread.h> API instead which shields them from
|
|
|
|
implementation details and provides a higherlevel interface that
|
|
|
|
prevents bugs and code duplication

Class devices should not carry any of these properties, and bus

|

So it _could_ be removed _any_ time now, if it conflicts with something new.
|
2008-01-28 15:47:41 -07:00

resource limits
|
|
|
|
When: 2.6.31
|
|
|
|
Why: Non root users need to be part of /proc/sys/vm/hugetlb_shm_group or
|
|
|
|
have CAP_IPC_LOCK to be able to allocate shm segments backed by
|
|
|
|
huge pages. The mlock based rlimit check to allow shm hugetlb is

netfilter: accounting rework: ct_extend + 64bit counters (v4)
Initially netfilter has had 64bit counters for conntrack-based accounting, but
it was changed in 2.6.14 to save memory. Unfortunately in-kernel 64bit counters are
still required, for example for "connbytes" extension. However, 64bit counters
waste a lot of memory and it was not possible to enable/disable it runtime.
This patch:
- reimplements accounting with respect to the extension infrastructure,
- makes one global version of seq_print_acct() instead of two seq_print_counters(),
- makes it possible to enable it at boot time (for CONFIG_SYSCTL/CONFIG_SYSFS=n),
- makes it possible to enable/disable it at runtime by sysctl or sysfs,
- extends counters from 32bit to 64bit,
- renames ip_conntrack_counter -> nf_conn_counter,
- enables accounting code unconditionally (no longer depends on CONFIG_NF_CT_ACCT),
- set initial accounting enable state based on CONFIG_NF_CT_ACCT
- removes buggy IPCT_COUNTER_FILLING event handling.
If accounting is enabled newly created connections get additional acct extend.
Old connections are not changed as it is not possible to add a ct_extend area
to confirmed conntrack. Accounting is performed for all connections with
acct extend regardless of a current state of "net.netfilter.nf_conntrack_acct".

What: fakephp and associated sysfs files in /sys/bus/pci/slots/
|
|
|
|
When: 2011
|
|
|
|
Why: In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to
|
|
|
|
represent a machine's physical PCI slots. The change in semantics
|
|
|
|
had userspace implications, as the hotplug core no longer allowed
|
|
|
|
drivers to create multiple sysfs files per physical slot (required
|
|
|
|
for multi-function devices, e.g.). fakephp was seen as a developer's
|
|
|
|
tool only, and its interface changed. Too late, we learned that
|
|
|
|
there were some users of the fakephp interface.
|
|
|
|
|
|
|
|
In 2.6.30, the original fakephp interface was restored. At the same
|
|
|
|
time, the PCI core gained the ability that fakephp provided, namely
|
|
|
|
function-level hot-remove and hot-add.
|
|
|
|
|
|
|
|
Since the PCI core now provides the same functionality, exposed in:
|
|
|
|
|
|
|
|
/sys/bus/pci/rescan
|
|
|
|
/sys/bus/pci/devices/.../remove
|
|
|
|
/sys/bus/pci/devices/.../rescan
|
|
|
|
|
|
|
|
there is no functional reason to maintain fakephp as well.
|
|
|
|
|
|
|
|
We will keep the existing module so that 'modprobe fakephp' will
|
|
|
|
present the old /sys/bus/pci/slots/... interface for compatibility,
|
|
|
|
but users are urged to migrate their applications to the API above.
|
|
|
|
|
|
|
|
After a reasonable transition period, we will remove the legacy
|
|
|
|
fakephp interface.

What: sound-slot/service-* module aliases and related clutters in
|
|
|
|
sound/sound_core.c
|
|
|
|
When: August 2010
|
|
|
|
Why: OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR
|
|
|
|
(14) and requests modules using custom sound-slot/service-*
|
|
|
|
module aliases. The only benefit of doing this is allowing
|
|
|
|
use of custom module aliases which might as well be considered
|
|
|
|
a bug at this point. This preemptive claiming prevents
|
|
|
|
alternative OSS implementations.
|
|
|
|
|
|
|
|
Till the feature is removed, the kernel will be requesting
|
|
|
|
both sound-slot/service-* and the standard char-major-* module
|
|
|
|
aliases and allow turning off the pre-claiming selectively via
|
|
|
|
CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss
|
|
|
|
kernel parameter.
|
|
|
|
|
|
|
|
After the transition phase is complete, both the custom module
|
|
|
|
aliases and switches to disable it will go away. This removal
|
|
|
|
will also allow making ALSA OSS emulation independent of
|
|
|
|
sound_core. The dependency will be broken then too.

What: Support for lcd_switch and display_get in asus-laptop driver
|
|
|
|
When: March 2010
|
|
|
|
Why: These two features use non-standard interfaces. There are the
|
|
|
|
only features that really need multiple path to guess what's
|
|
|
|
the right method name on a specific laptop.
|
|
|
|
|
|
|
|
Removing them will allow to remove a lot of code an significantly
|
|
|
|
clean the drivers.
|
|
|
|
|
|
|
|
This will affect the backlight code which won't be able to know
|
|
|
|
if the backlight is on or off. The platform display file will also be
|
|
|
|
write only (like the one in eeepc-laptop).
|
|
|
|
|
|
|
|
This should'nt affect a lot of user because they usually know
|
|
|
|
when their display is on or off.

|
|
|
|
Why: The vtx device nodes have been superseded by vbi device nodes
|
|
|
|
for many years. No applications exist that use the vtx support.
|
|
|
|
Of the two i2c drivers that actually support this API the saa5249
|
|
|
|
has been impossible to use for a year now and no known hardware
|
|
|
|
that supports this device exists. The saa5246a is theoretically
|
|
|
|
supported by the old mxb boards, but it never actually worked.
|
|
|
|
|
|
|
|
In summary: there is no hardware that can use this API and there
|
|
|
|
are no applications actually implementing this API.
|
|
|
|
|
|
|
|
The vtx support still reserves minors 192-223 and we would really
|
|
|
|
like to reuse those for upcoming new functionality. In the unlikely
|
|
|
|
event that new hardware appears that wants to use the functionality
|
|
|
|
provided by the vtx API, then that functionality should be build
|
|
|
|
around the sliced VBI API instead.
