[ Upstream commit 8e7a65aa70bcc1235a44e40ae0da5056525fe081 ]
We accidentally lost the initial DPLL register write in
1c4e02746147 drm/i915: Fix DVO 2x clock enable on 830M
The "three times for luck" hack probably saved us from a total
disaster. But anyway, bring the initial write back so that the
code actually makes some sense.

[ Upstream commit 2a6c521bb41ce862e43db46f52e7681d33e8d771 ]
On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.
This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up
in the wrong place.

which meant that in some cases the driver was not finished

We need to do this in order to prevent accesses to the device while it's
powered down. Userspace may have an mmap of the fb, and there's no good
way (that I know of) to prevent it from touching the device otherwise.
This fixes some nasty races between runpm and plymouth on some systems,
which result in the GPU getting very upset and hanging the boot.

[ Upstream commit bd3e1c7c6de9f5f70d97cdb6c817151c0477c5e3 ]
Due to some recent changes in
drm_helper_probe_single_connector_modes_merge_bits(), old custom modes
were not being pruned properly. In current kernels,
drm_mode_validate_basic() is called to sanity-check each mode in the
list. If the sanity-check passes, the mode's status gets set to to
MODE_OK. In older kernels this check was not done, so old custom modes
would still have a status of MODE_UNVERIFIED at this point, and would
therefore be pruned later in the function.
As a result of this new behavior, the list of modes for a device always
includes every custom mode ever configured for the device, with the
largest one listed first. Since desktop environments usually choose the
first preferred mode when a hotplug event is emitted, this had the
result of making it very difficult for the user to reduce the size of
the display.
The qxl driver did implement the mode_valid connector function, but it
was empty. In order to restore the old behavior where old custom modes
are pruned, we implement a proper mode_valid function for the qxl
driver. This function now checks each mode against the last configured
custom mode and the list of standard modes. If the mode doesn't match
any of these, its status is set to MODE_BAD so that it will be pruned as
expected.

[ Upstream commit da168d81b44898404d281d5dbe70154ab5f117c1 ]
I've done some extensive history digging across libdrm, mesa and
xf86-video-{intel,nouveau,ati}. The only potential user of this with
kms drivers I could find was ttmtest, which once used drmGetLock
still. But that mistake was quickly fixed up. Even the intel xvmc
library (which otherwise was really good with using dri1 stuff in kms
mode) managed to never take the hw lock for dri2 (and hence kms).
Hence it should be save to unconditionally disallow this.

[ Upstream commit cd67d226ebd909d239d2c6e5a6abd6e2a338d1cd ]
The VBT MIPI Sequence Block version 3 has forward incompatible changes:
First, the block size in the header has been specified reserved, and the
actual size is a separate 32-bit value within the block. The current
find_section() function to will only look at the size in the block
header, and, depending on what's in that now reserved size field,
continue looking for other sections in the wrong place.
Fix this by taking the new block size field into account. This will
ensure that the lookups for other sections will work properly, as long
as the new 32-bit size does not go beyond the opregion VBT mailbox size.
Second, the contents of the block have been completely
changed. Gracefully refuse parsing the yet unknown data version.

[ Upstream commit 3e04e2fe6d87807d27521ad6ebb9e7919d628f25 ]
This addresses two issues that cause problems with viewperf maya-03 in
situation with memory pressure.
The first issue causes attempts to unreserve buffers if batched
reservation fails due to, for example, a signal pending. While previously
the ttm_eu api was resistant against this type of error, it is no longer
and the lockdep code will complain about attempting to unreserve buffers
that are not reserved. The issue is resolved by avoid calling
ttm_eu_backoff_reservation in the buffer reserve error path.
The second issue is that the binding_mutex may be held when user-space
fence objects are created and hence during memory reclaims. This may cause
recursive attempts to grab the binding mutex. The issue is resolved by not
holding the binding mutex across fence creation and submission.

In order for hibernation to reliably work we need to cleanup more
thoroughly the compute ring. Hibernation is different from suspend
resume as when we resume from hibernation the hardware is first
fully initialize by regular kernel then freeze callback happens
(which correspond to a suspend inside the radeon kernel driver)
and turn off each of the block. It turns out we were not cleanly
shutting down the compute ring. This patch fix that.

If the function fails reference counter to the object is not decremented
causing leaks.
This is hard to spot as it happens only on very low memory situations.

Laptop with Turks/Thames GPU will freeze if dpm is enabled. It seems
the SMC engine is relying on some state inside the CP engine. CP needs
to chew at least one packet for it to get in good state for dynamic
power management.
This patch simply disabled and re-enable DPM after the ring test which
is enough to avoid the freeze.

[ Upstream commit 3f5f1554ee715639e78d9be87623ee82772537e0 ]
Passive DP->DVI/HDMI dongles on DP++ ports show up to the system as HDMI
devices, as they do not have a sink device in them to respond to any AUX
traffic. When probing these dongles over the DDC, sometimes they will
NAK the first attempt even though the transaction is valid and they
support the DDC protocol. The retry loop inside of
drm_do_probe_ddc_edid() would normally catch this case and try the
transaction again, resulting in success.
That, however, was thwarted by the fix for [1]:

drm: give up on edid retries when i2c bus is not responding
This added code to exit immediately if the return code from the
i2c_transfer function was -ENXIO in order to reduce the amount of time
spent in waiting for unresponsive or disconnected devices. That was
possible because the underlying i2c bit banging algorithm had retries of
its own (which, of course, were part of the reason for the bug the
commit fixes).
Since its introduction in

Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Tue Jul 20 15:44:45 2010 -0700
drm/i915: use GMBUS to manage i2c links
we've been flipping back and forth enabling the GMBUS transfers, but
we've settled since then. The GMBUS implementation does not do any
retries, however, bailing out of the drm_do_probe_ddc_edid() retry loop
on first encounter of -ENXIO. This, combined with Eugeni's commit, broke
the retry on -ENXIO.
Retry GMBUS once on -ENXIO on first message to mitigate the issues with
passive adapters.
This patch is based on the work, and commit message, by Todd Previte

According to the HSW b-spec we need to try clock divisors of 63
and 72, each 3 or more times, when attempting DP AUX channel
communication on a server chipset. This actually wasn't happening

in status rather than checking that the operation was done and
that DP_AUX_CH_CTL_TIME_OUT_ERROR was not set.

[ Upstream commit 944115934436b1ff6cf773a9e9123858ea9ef3da ]
Haswell significantly improved the performance of sampler_c messages,
but the optimization appears to be off by default. Later platforms
remove this bit, and apparently always enable the optimization.
Improves performance in "Counter Strike: Global Offensive" by 18%
at default settings on Iris Pro.
This may break sampling of paletted formats (P8/A8P8/P8A8). It's
unclear whether it affects sampling of paletted formats in general,
or just the sample_c message (which is never used).
While libva does have support for using paletted formats (primarily
for OSDs), that support appears to have been broken for at least a
year, so I couldn't observe a regression from this:
I tried to get libva-intel to use paletted formats, and observe a
regression...but the only thing I found that used it was mplayer's OSD
(on screen display). Even without my patch, the colors were totally
wrong with that, and it's according to a few distro wikis, that's been
the case for over a year.
If libva's code for paletted formats /is/ broken, they could always
add code to disable this bit using the command validator when fixing
it.
Further investigation from Haihao shows that libva mplayer OSD seems
to work at least on his setup (still unclear what's wron with Ken's),
and that it's not affected by this patch. Quoting the discussion

You are right, libva driver doesn't use sample_c message.
