Daniel Vetter 7f6658ef35 drm/i915: VGA needs to be on pipe A on i830M
The bit doesn't stick, and the output is always cloned from pipe A,
even when it's supposed to scan out from pipe B.

Shuts up annoying warnings from the modeset-rework, too.

I've noticed that with this patch we know get and unknown connection
state since the code can't find a suitable pipe for load detection.
But that beats the previous state of affairs, where it tried to use
pipe B, actually used pipe A and concluded that something is connected
(although it's the LVDS on pipe A and nothing on the VGA connector on
pipe B).

I've tried to make load detect work by remapping the pipe->planes
stuff, so that crtc 0 will use pipe B and hence we still have
something left for load-detect on pipe A. But alas, that upset the hw
a bit.

So there's still some things to figure out, but this here will at
least paper over some of the problems.

Daniel Vetter a9193983f4 drm/i915: fix overlay on i830M
The overlay on the i830M has a peculiar failure mode: It works the
first time around after boot-up, but consistenly hangs the second time
it's used.

Chris Wilson has dug out a nice errata:

"1.5.12 Clock Gating Disable for Display Register
Address Offset:	06200h–06203h

"Bit 3
Ovrunit Clock Gating Disable.
0 = Clock gating controlled by unit enabling logic
1 = Disable clock gating function
DevALM Errata ALM049: Overlay Clock Gating Must be Disabled:  Overlay
& L2 Cache clock gating must be disabled in order to prevent device
hangs when turning off overlay.SW must turn off Ovrunit clock gating
(6200h) and L2 Cache clock gating (C8h)."

Now I've nowhere found that 0xc8 register and hence couldn't apply the
l2 cache workaround. But I've remembered that part of the magic that
the OVERLAY_ON/OFF commands are supposed to do is to rearrange cache
allocations so that the overlay scaler has some scratch space.

And while pondering how that could explain the hang the 2nd time we
enable the overlay, I've remembered that the old ums overlay code did
_not_ issue the OVERLAY_OFF cmd.

And indeed, disabling the OFF cmd results in the overlay working
flawlessly, so I guess we can workaround the lack of the above
workaround by simply never disabling the overlay engine once it's
enabled.

Note that we have the first part of the above w/a already implemented
in i830_init_clock_gating - leave that as-is to avoid surprises.

v2: Add a comment in the code.

Thomas Hellstrom b8e902f24f drm/ttm: Fix a theoretical race in ttm_bo_cleanup_refs()
In theory, that function could release the lru lock between
checking for bo on ddestroy list and a successful reserve if the bo
was already reserved, and the function was called with waiting reserves
allowed.
However, all current reservers of a bo on the ddestroy list would
atomically take the bo off the list after a successful reserve so this
race should not have been hit, so no need to backport for stable.

This patch also fixes a case found by Maarten Lankhorst where
ttm_mem_evict_first called with no_wait_gpu would incorrectly
spin waiting for bo idle if trying to evict a busy buffer that
also sits on the ddestroy list.

Daniel writes:
The big thing is the disabling of the hsw support by default, cc: stable.
We've aimed for basic hsw support in 3.6, but due to a few bad
happenstances we've screwed up and only 3.8 will have better modeset
support than vesa. To avoid yet another round of fallout from such a
gaffle on for the next platform we've added a module option to disable
early hw support by default. That should also give us more flexibility in
bring-up.

 Otherwise just small fixes:
 - 3 fixes from Egbert for sdvo corner cases
 - invert-brightness quirk entry from Egbert
 - revert a dp link training change, it regresses some setups
 - and shut up a spurious WARN in our gem fault handler.

Rodrigo Vivi 0a3af26864 drm/i915: Insert i915_preliminary_hw_support variable.
On the worst scenario, users with new hardwares and old kernel from
enabling times can get black screens.  So, from now on, this
perliminary_hw_support module parameter shall be used by all upcoming
platforms that are still under enabling. The second option would be to
merge the pci ids after basic modeset works, but that makes testing
and development while bringing up hw a rather tedious afair.

Although it is uncomfortable for developers use this extra variable it
brings more stability for end users.

Daniel Vetter b06fbda328 Revert "drm/i915: Try harder to complete DP training pattern 1"
This reverts commit 2477367083.

If (for whatever reason) the DP sink device never asks for the maximal
voltage level, we never don't hit the check that should bail us out
after 5 retries of the same voltage. Which leads to an endless loop in
the DP link training code, which hangs the driver.

Now some more DP link training experiments on eDP panels seem to
indicate that our training algorithm isn't robust enough anyway and
needs more work. Hence for 3.7-fixes, let's just revert the regressing
commit instead of trying to apply more duct-tape.

Egbert Eich e751823da2 DRM/i915: Restore sdvo_flags after dtd->mode->dtd Roundrtrip.
For TV and LVDS encoders intel_sdvo_set_input_timings_for_mode()
is called to pass a mode to the sdvo chip and retrieve a dtd
containing information needed to calculate the adjusted_mode which
is done by intel_sdvo_get_dtd_from_mode().
To set this adjusted_mode as input mode for the sdvo chip, a dtd is
recalculated using intel_sdvo_get_mode_from_dtd(). During this round
trip the sdvo_flags contained in the dtd obtained from the hardware
are lost.
Since these flags cannot be ignored in all cases this patch preserves
and restores them.

This regression has been introduced in

The DPLL multipiler is set up in intel_display.c:i9xx_update_pll()

There the DPLL multiplier is adjusted so that the SDVO gets a sufficient

When cloning a CRTC between an SDVO driven encoder and the standard
DAC the DAC setup code reseted the multiplier value to 1 thus undoing
the correct setup. There is no need to touch the multiplier in the DAC
setup code: the correct value (i.e. 1 in case no SDVO encoder is used)
is set by i9xx_update_pll() already.
A comment at the code suggested that this code is a left over from the

Egbert Eich 0829184711 drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().
radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

Christian König 90a51a3292 drm/radeon: allocate page tables on demand v4
Based on Dmitries work, but splitting the code into page
directory and page table handling makes it far more
readable and (hopefully) more reliable.

Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.

high memory pressure) to group updates send to the chipset

thus module reload on affected machines.

We need to check whether the _other plane is on our pipe, not whether

gen2/3 feature, so test for that instead of PCH_SPLIT

pipe, to avoid upsetting i845g/i865g. Noticed by Chris Wilson.

Daniel Vetter ccd0d36e2a drm/i915: rip out the pipe A quirk for i855gm
This seems to be the root-cause that breaks resume on my i855gm when I
apply the "drm/i915: fixup the plane->pipe fixup code" patch. And that
code doesn't even run on my machine, so it's pure timing changes
causing the regression.

Furthermore resume has been constantly switching between working and
broken on this machine ever since kms support has been merged,
seemingly with no related change as a root cause. And always with the
same symptoms of the backlight lighting up, but the lvds panel only
displaying black.

Also, of both i855gm variants only one is in the table. And in the
past we've only ever removed entries from this quirk table because it
breaks things.

So let's just remove it - in case there's indeed a bios out there
relying on a running pipe A, we can add back in a more precise quirk
entry, like all the others (save for i830/i845).

Chris Wilson acb868d3d7 drm/i915: Disallow preallocation of requests
The intention was to allow the caller to avoid a failure to queue a
request having already written commands to the ring. However, this is a
moot point as the i915_add_request() can fail for other reasons than a
mere allocation failure and those failure cases are more likely than
ENOMEM. So the overlay code already had to handle i915_add_request()
failures, and due to

    drm/i915: Allow late allocation of request for i915_add_request()

the error handling code in intel_overlay.c was subject to causing
double-frees, as found by coverity.

Rather than further complicate i915_add_request() and callers, realise
the battle is lost and adapt intel_overlay.c to take advantage of the
late allocation of requests.

v2: Handle callers passing in a NULL seqno.
v3: Ditto. This time for sure.

The game "Dante" demonstrates random clipping issues when guardband
clipping is enabled and bit 5 of 3D_CHICKEN3 isn't set.  So the
workaround is actually necessary.

Konstantin Khlebnikov 314e51b985 mm: kill vma flag VM_RESERVED and mm->reserved_vm counter
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:

 | effect                 | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump      | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock           | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP

This patch removes reserved_vm counter from mm_struct.  Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.

Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.

remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

Daniel Vetter 6ce9410047 drm/i915: paper over a pipe-enable vs pageflip race
I've discovered this on my ivb machine while stress-testing the new
flip_tests. Only harmful effect observed is that the timestamp is a
bit bogus.

Note that this is empirical duct-tape: I've noticed that we seem to
only ever miss the very first vblank irq right after enabling the
pipe. And with this hack applied I couldn't reproduce the failure case
anywhere else any more.

Quoting Chris :
  "That BUG_ON there is silly and can simply be removed. The check is to
   verify that no batches were submitted to the kernel whilst the UMS/GEM
   client was suspended - to which the BUG_ONs are a crude approximation.
   Furthermore, the checks are too late, since it means we attempted to

   the least of your concerns at that point."

... since finish_page_flip needs the vblank timestamp generated
in drm_handle_vblank. Somehow all the gmch platforms get it right,
but all the pch platform irq handlers get is wrong. Hooray for copy&

Currently this gets papered over by a gross hack in finish_page_flip.
A second patch will remove that.

Note that without this, the new timestamp sanity checks in flip_test
occasionally get tripped up, hence the cc: stable tag.

Linus Torvalds 612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's

Joonyoung Shim fab9f8d093 drm/exynos: fix kcalloc size of g2d cmdlist node
The size argument means just one element size when we call kcalloc, so
G2D_CMDLIST_NUM * sizeof(*node) is wrong.

Inki Dae 58f6aad7d9 drm/exynos: fix display power call issue.
Changelog v3:
make exynos_drm_display_power function use exynos_drm_best_encoder
function instead of connector->encoder to get a valid encoder.
connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB
request, connector->encoder is NULL so fix this issue.

Changelog v2:
remove static prefix so that exynos_drm_best_encoder function
could be called by other modules.

Changelog v1:
this patch fixes the issue that display power callback isn't called.
with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL
so display_ops->power_on() wouldn't be called so this patch makes
exynos_drm_best_encoder function to be used to get a valid encoder
of each connector.

Sachin Kamat 53bd555654 drm/exynos: Fix potential NULL pointer dereference
drm_mode_create() returns NULL if it fails to create
a new display mode. Check the value returned to avoid NULL
pointer deferencing later.
