8 years agofbcon: fix situation where fbcon gets deinitialised and can't reinit.
Dave Airlie [Tue, 21 Dec 2010 01:41:17 +0000]
fbcon: fix situation where fbcon gets deinitialised and can't reinit.

Situation as follow:
2 GPUs + vesafb + kms.

GPU 1 is primary, vesafb binds to it as fb0
radeon loads
GPU 0 loads as fb1
GPU 1 loads, vesafb gets kicked off which causes fb0 to unbind
console, which causes the dummy console to rebind.

this means fbcon_deinit gets called, which calls fbcon_exit
since the console isn't bound anymore and we set fbcon_has_exited.

GPU 1 creates a new fb0 which is primary and we want to be console.
fbcon_fb_registered gets called sets the primary up and calls set_con2fb_map,
however as fbcon_has_exited is set nothing further ever happens.

This patch bypasses the fbcon_has_exited and checks if the console is unbound,
if its unbound it calls the fbcon_takeover which calls the vt layer to
call the fbcon_startup method and everthing works.

8 years agovideo: Fix EDID macros H_SYNC_WIDTH and H_SYNC_OFFSET
Martin Decky [Sun, 13 Feb 2011 19:28:40 +0000]
video: Fix EDID macros H_SYNC_WIDTH and H_SYNC_OFFSET

The macros for getting the values for horizontal sync width and offset
do not respect the EDID specification. Both these values are 10 bit
values according to [1], not 6 bit values. The lower 8 bits are stored
in byte 8 and byte 9 of the DTD respectively, while two additional bits
for each value are stored in byte 11. The original macros just slammed
the bits together.

Although the original macros usually worked fine because the higher two
bits are rarely used, it can cause severe problems on plasma panels
running at 1920x1080 @ 50 Hz with drivers that rely on the correct
parsing of the EDID data by fbmon.c (e.g. udlfb).

The patch should apply cleanly to both the fbdev-2.6.git branch and
linux-next.git branch.

8 years agouvesafb,vesafb: create WC or WB PAT-entries
Thomas Schlichter [Sat, 27 Nov 2010 13:17:55 +0000]
uvesafb,vesafb: create WC or WB PAT-entries

with an PAT-enabled kernel, when using uvesafb or vesafb, these drivers will
create uncached-minus PAT entries for the framebuffer memory because they use
ioremap() (not the *_cache or *_wc variants). When the framebuffer memory
intersects with the video RAM used by Xorg, the complete video RAM will be
mapped uncached-minus what results in a serve performance penalty.

Here are the correct MTRR entries created by uvesafb:
schlicht@netbook:~$ cat /proc/mtrr
reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x06ff00000 ( 1791MB), size= 1MB, count=1: uncachable
reg02: base=0x070000000 ( 1792MB), size= 256MB, count=1: uncachable
reg03: base=0x0d0000000 ( 3328MB), size= 16MB, count=1: write-combining

And here are the problematic PAT entries:
schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list
PAT memtype list:
write-back @ 0x0-0x1000
uncached-minus @ 0x6fedd000-0x6fee3000
uncached-minus @ 0x6fee2000-0x6fee3000

uncached-minus @ 0xf5404000-0xf5405000
uncached-minus @ 0xfed00000-0xfed01000

Therefore I created the attached patch for uvesafb which uses ioremap_wc() to
create the correct PAT entries, as shown below:
schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list

uncached-minus @ 0xf5404000-0xf5405000
uncached-minus @ 0xfed00000-0xfed01000

This results in a performance gain, objectively measurable with e.g.
x11perf -comppixwin10 -comppixwin100 -comppixwin500:
1: x11perf_xaa.log
2: x11perf_xaa_patched.log

   131.0   1150.0 ( 8.78) Composite 500x500 from pixmap to window

You can see the serve performance gain when composing larger pixmaps to window.

The patches replace the ioremap() function with the variant matching the mtrr-
parameter. To create "write-back" PAT entries, the ioremap_cache() function
must be called after creating the MTRR entries, and the ioremap_cache() region
must completely fit into the MTRR region, this is why the MTRR region size is
now rounded up to the next power-of-two.

Jesper Juhl [Mon, 21 Mar 2011 19:47:31 +0000]
Reduce sequential pointer derefs in scsi_error.c and reduce size as well

This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c

This has been submitted a number of times over a couple of years.  I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.

The benefits are:

 - makes the code easier to read.  Lots of sequential derefs of the same
   pointers is not easy on the eye.

 - theoretically at least, just dereferencing the pointers once can
   allow the compiler to generally slightly faster code, so in theory
   this could also be a micro speed optimization.

 - reduces size of object file (tiny effect: on x86-64, in at least one
   configuration, the text size decreased from 9439 bytes to 9400)

 - removes some pointless (mostly trailing) whitespace.

8 years agomatroxfb: remove incorrect Matrox G200eV support
Gary Hade [Mon, 21 Mar 2011 17:28:59 +0000]
matroxfb: remove incorrect Matrox G200eV support

Remove incorrect Matrox G200eV support that was previously added by
commit e3a1938805d2e81b27d3d348788644f3bad004f2

A serious issue with the incorrect G200eV support that reproduces on the
Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
banner, login prompt, etc) on the console when X is not running and
total lack of text on all of the virtual consoles after X is started.

Any concerns that the incorrect code (upstream since October 2008) has
been successfully used on non-IBM G200eV equipped system(s) appear to be
unwarranted.  In addition to the serious/non-intermittent nature of
issues that have been spotted on IBM systems, complete removal of the
incorrect code is clearly supported by the following Matrox (Yannick
Heneault) provided input:
 "It impossible that this patch should have work on a system.
 The patch only declare the G200eV as a regular G200 which is
 not case. Many registers are different, including at least the
 PLL programming sequence. If the G200eV is programmed like a
 regular G200, it will not display anything."

v1 - Initial patch that removed the incorrect code for _all_
     G200eV equipped systems.
v2 - Darrick Wong provided patch that blacklisted the incorrect
     code on G200eV equipped IBM systems leaving it enabled on
     all G200eV equipped non-IBM systems.
v3 - Same code changes included with v1 plus additional
     justification for complete removal of the incorrect code.

8 years agoPrevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code
Julien Tinnes [Fri, 18 Mar 2011 22:05:21 +0000]
Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code

Userland should be able to trust the pid and uid of the sender of a
signal if the si_code is SI_TKILL.

Unfortunately, the kernel has historically allowed sigqueueinfo() to
send any si_code at all (as long as it was negative - to distinguish it
from kernel-generated signals like SIGILL etc), so it could spoof a
SI_TKILL with incorrect siginfo values.

Happily, it looks like glibc has always set si_code to the appropriate
SI_QUEUE, so there are probably no actual user code that ever uses
anything but the appropriate SI_QUEUE flag.

So just tighten the check for si_code (we used to allow any negative
value), and add a (one-time) warning in case there are binaries out
there that might depend on using other si_code values.

* Check for unused bits in the configuration register as soon as we
  have read its value.
* Don't use word reads, not all devices support this, and some which
  don't misbehave when you try.
* Check for cycling register values every 40 register addresses
  instead of every 8, it's 5 times faster and just as efficient.

Akinobu Mita [Mon, 21 Mar 2011 12:32:53 +0000]
bfs: fix bitmap size argument to find_first_zero_bit()

The usage of find_first_zero_bit() in bfs_create() is wrong for two
reasons.

The bitmap size argument to find_first_zero_bit() is info->si_lasti but
the correct bitmap size is info->si_lasti + 1 as info->si_lasti is the
last valid index in info->si_imap bitmap.

Another problem is that it is impossible to detect that info->si_imap
bitmap is full because there is an off-by-one bug in the return value
check for find_first_zero_bit().  If no zero bits exist in info->si_imap,
find_first_zero_bit() returns info->si_lasti.  But the check can't catch
it due to the off-by-one.

8 years agointroduce sys_syncfs to sync a single file system
Sage Weil [Thu, 10 Mar 2011 19:31:30 +0000]
introduce sys_syncfs to sync a single file system

It is frequently useful to sync a single file system, instead of all
mounted file systems via sync(2):

 - On machines with many mounts, it is not at all uncommon for some of
   them to hang (e.g. unresponsive NFS server).  sync(2) will get stuck on
   those and may never get to the one you do care about (e.g., /).
 - Some applications write lots of data to the file system and then
   want to make sure it is flushed to disk.  Calling fsync(2) on each
   file introduces unnecessary ordering constraints that result in a large
   amount of sub-optimal writeback/flush/commit behavior by the file
   system.

There are currently two ways (that I know of) to sync a single super_block:

 - BLKFLSBUF ioctl on the block device: That also invalidates the bdev
   mapping, which isn't usually desirable, and doesn't work for non-block
   file systems.
 - 'mount -o remount,rw' will call sync_filesystem as an artifact of the
   current implemention.  Relying on this little-known side effect for
   something like data safety sounds foolish.

Both of these approaches require root privileges, which some applications
do not have (nor should they need?) given that sync(2) is an unprivileged
operation.

This patch introduces a new system call syncfs(2) that takes an fd and
syncs only the file system it references.  Maybe someday we can

 $ sync /some/path

and not get

 sync: ignoring all arguments

The syscall is motivated by comments by Al and Christoph at the last LSF.
syncfs(2) seems like an appropriate name given statfs(2).

A similar ioctl was also proposed a while back, see
