534843dabf drm/i915: Use 128k alignment for untiled display surface on i965 (v2)
The original i965, including the revised G35 and Q35, requires an
alignment of 128K for the display surface with linear memory, so
increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)

Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.

v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

e1a4474349 drm/i915/pch: Cosmetic fix to FDI link training
Unmask the bits for link training reporting before starting link
training.  If stage 1 training finished before we unmask them, then we'd
spin around in a loop a few times until smashing on through.  Which is
harmless, since training _did_ succeed, it just looks ugly in dmesg.

2991196fbc drm/i915: cleanup: use ARRAY_SIZE()
NUM_TV_MODES is the same as ARRAY_SIZE(tv_modes).  In the end, I
decided it was cleaner to remove NUM_TV_MODES and just use
ARRAY_SIZE(tv_modes) through out.

0b3400040d drm/i915: Remove the WARN when failing to set tiling.
We generally issue an error message at the point of failure, and so this
warning with a fairly pointless stacktrace is superfluous and ugly.
Needless to say, the common trigger for this WARN happens to be EIO
where this is pure noise.

2377b741ab drm/i915: fix FDI frequency check
Since mode->clock is in kHz we should be checking against 2700000
instead of just 27000.  This patch gets my x201s working again (well
working as well as it ever was anyway).

When looking for this I also noticed we set link_bw to 270000, but the
calculation is different.  Does it also need to use kHz or we using
10kHz internally?

167ffc44ca drm: radeon: fix sign bug
The "error" variable is unsigned so it's never less than zero.  I
changed it to check if (freq < current_freq) directly.

"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative.  Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.

4c712e6c7e drm/radeon/kms: check/restore sanity before doing anything else with GPU.
On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset.

Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system.

This allows kexec to work on a Power6/RN50 system.

Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC
reference clock.

More generally, the 0.488% tolerance used before is just too tight to
reliably find a PLL setting.  I extracted the search algorithm and
modified it to find the dot clocks with maximum error over the valid
range for the given output type:

http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c

This gave:

Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571)
Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524)
Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488)
Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529)
Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488)
Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448)
Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478)
Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449)

f1feda70b5 drm/nouveau: Put back the old 2-messages I2C slave test.
I was hoping we could detect I2C devices at a given address without
actually writing data into them, but apparently some DDC slaves get
confused with 0-bytes transactions. Put the good old test back.

e04d8e829d drm/nouveau: Reset AGP before running the init scripts.
BIOS scripts usually make an attempt to reset the AGP controller,
however on some nv4x cards doing it properly involves switching FW off
and on: if we do that without updating the AGP bridge settings
accordingly (e.g. with the corresponding calls to agp_enable()) we
will be locking ourselves out of the card MMIO space. Do it from
nouveau_mem_reset_agp() before the init scripts are executed.

Init-compute-mem was the last piece missing for nv0x-nv3x card
cold-booting. This implementation is somewhat lacking but it's been
reported to work on most chipsets it was tested in. Let me know if it
breaks suspend to RAM for you.
