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 @ 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
PAT memtype list:

This results in a performance gain, objectively measurable with e.g.
x11perf -comppixwin10 -comppixwin100 -comppixwin500:
1: x11perf_xaa.log
2: x11perf_xaa_patched.log
1 2 Operation
-------- ---------------- -----------------
124000.0 202000.0 ( 1.63) Composite 10x10 from pixmap to window
3340.0 24400.0 ( 7.31) Composite 100x100 from pixmap to window
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.

Some Radeon cards have an I2C-based thermal sensor chip connected to
the "monid" I2C bus. Set the I2C probing class of this bus properly so
that hwmon drivers can detect devices on it and bind to them.
This closes kernel.org bug #26172.
We exclude PPC for the time being, as Benjamin doesn't want us to
mess up with them without explicit testing, and there is no evidence
that this change is needed for them either.

Currently there is no indication if R/W test fails during POST. This can
happen e.g. when user plugs in a card with unsupported type of memory.
Since the driver will be unusable, it's better to fail the whole POST

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.

Add dss.dpll4_m4_ck (DSS FCLK) initialization for OMAP4. This is used
to compute the pixel clock for DPI interface and also to reconfigure
the DSS FCLK to the desired rate, corresponding to the rate computed
for pixel clock.
Adding these cpu_is_44xx() checks are meant to be temporary, until a
cleaner implementation to manage these checks are added. Currently this
is needed to get DVI display running on OMAP4 PandaBoard

OMAP2 does not have dpll4_m4_ck source clock for dss functional clock,
but later OMAPs do. Currently we check for cpu type in multiple places
to find out if dpll4_m4_ck is available.
This patch cleans up dss.c by using the fact that dss.dpll4_m4_ck
pointer is NULL on OMAP2. This allows us to remove many of the cpu
checks.
