Dave Airlie 29508eb66b drm/radeon/kms: drop taking lock around crtc lookup.
We only add/remove crtcs at driver load, you cannot remove when
the GPU is running a CS packet since the fd is open, when
GPU hotplugging on radeons actually is needed all this locking
needs a review and I've started re-working kms core locking to deal
with this better. But for now avoid long delays in CS processing when
hotplug detect is happening in a different thread.

this fixes a regression introduced with hotplug detection.

Alex Deucher 42f14c4b45 drm/radeon/kms: fix shared ddc harder
This fixes a regression caused by b2ea4aa67b
due to the way shared ddc with multiple digital connectors was handled.

You generally have two cases where DDC lines are shared:
- HDMI + VGA
- HDMI + DVI-D

HDMI + VGA is easy to deal with because you can check the EDID for the
to see if the attached monitor is digital.  A shared DDC line with two
digital connectors is more complex.  You can't use the hdmi bits in the
EDID since they may not be there with DVI<->HDMI adapters.  In this case
all we can do is check the HPD pins to see which is connected as we have
no way of knowing using the EDID.

Dave Airlie 944001201c drm/i915: enable low power render writes on GEN3 hardware.
A lot of 945GMs have had stability issues for a long time, this manifested as X hangs, blitter engine hangs, and lots of crashes.

one such report is at:
https://bugs.freedesktop.org/show_bug.cgi?id=20560

along with numerous distro bugzillas.

This only took a week of digging and hair ripping to figure out.

Tracked down and tested on a 945GM Lenovo T60,
previously running
x11perf -copypixwin500
or
x11perf -copywinpix500
repeatedly would cause the GPU to wedge within 4 or 5 tries, with random busy bits set.

After this patch no hangs were observed.

Dave Chinner 7f8275d0d6 mm: add context argument to shrinker callback
The current shrinker implementation requires the registered callback
to have global state to work from. This makes it difficult to shrink
caches that are not global (e.g. per-filesystem caches). Pass the shrinker
structure to the callback so that users can embed the shrinker structure
in the context the shrinker needs to operate on and get back to it in the
callback via container_of().

Linus Torvalds cd9f040df6 drm/i915: add 'reclaimable' to i915 self-reclaimable page allocations
The hibernate issues that got fixed in commit 985b823b91 ("drm/i915:
fix hibernation since i915 self-reclaim fixes") turn out to have been
incomplete.  Vefa Bicakci tested lots of hibernate cycles, and without
the __GFP_RECLAIMABLE flag the system eventually fails to resume.

With the flag added, Vefa can apparently hibernate forever (or until he
gets bored running his automated scripts, whichever comes first).

The reclaimable flag was there originally, and was one of the flags that
were dropped (unintentionally) by commit 4bdadb9785 ("drm/i915:
Selectively enable self-reclaim") that introduced all these problems,
but I didn't want to just blindly add back all the flags in commit
985b823b91, and it looked like __GFP_RECLAIM wasn't necessary.  It
clearly was.

I still suspect that there is some subtle reason we're missing that
causes the problems, but __GFP_RECLAIMABLE is certainly not wrong to use
in this context, and is what the code historically used.  And we have no
idea what the causes the corruption without it.

Alex Deucher 8d369bb196 drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics
The asics in question have the following requirements with regard to
their gart setups:

1. The GART aperture size has to be in the form of 2^X bytes, where X is from 25 to 31
2. The GART aperture MC base has to be aligned to a boundary equal to the size of the
aperture.
3. The GART page table has to be aligned to the boundary equal to the size of the table.
4. The GART page table size is: table_entry_size * (aperture_size / page_size)
5. The GART page table has to be allocated in non-paged, non-cached, contiguous system
memory.

This patch takes care 2.  The rest should already be handled properly.

Jesse Barnes 023eb571a1 drm: correctly update connector DPMS status in drm_fb_helper
We don't currently update the DPMS status of the connector (both in the
connector itself and the connector's DPMS property) in the fb helper
code.  This means that if the kernel FB core has blanked the screen,
sysfs will still show a DPMS status of "on".  It also means that when X
starts, it will try to light up the connectors, but the drm_crtc_helper
code will ignore the DPMS change since according to the connector, the
DPMS status is already on.

Francisco Jerez 5870a4d97d drm/ttm: Allocate the page pool manager in the heap.
Repeated ttm_page_alloc_init/fini fails noisily because the pool
manager kobj isn't zeroed out between uses (we could do just that but
statically allocated kobjects are generally considered a bad thing).
Move it to kzalloc'ed memory.

Note that this patch drops the refcounting behavior of the pool
allocator init/fini functions: it would have led to a race condition
in its current form, and anyway it was never exploited.

This fixes a regression with reloading kms modules at runtime, since
page allocator was introduced.

Dan Carpenter ee0c6bfbd6 drm/i915: take struct_mutex in i915_dma_cleanup()
intel_cleanup_ring_buffer() calls drm_gem_object_unreference() (as
opposed to drm_gem_object_unreference_unlocked()) so it needs to be
called with "struct_mutex" held.  If we don't hold the lock, it triggers
a BUG_ON(!mutex_is_locked(&dev->struct_mutex));

I also audited the other places that call intel_cleanup_ring_buffer()
and they all hold the lock so they're OK.

This was introduced in: 8187a2b70e "drm/i915: introduce
intel_ring_buffer structure (V2)" and it's a regression from v2.6.34.

Andy Lutomirski 2d1c9752ea drm/i915: Fix CRT hotplug regression in 2.6.35-rc1
Commit 7a772c492f has two bugs which
made the hotplug problems on my laptop worse instead of better.

First, it did not, in fact, disable the CRT plug interrupt -- it
disabled all the other hotplug interrupts.  It seems rather doubtful
that that bit of the patch fixed anything, so let's just remove it.
(If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.)

Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64
and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset)
causes a hotplug interrupt about three seconds later.  The old code
never restored PORT_HOTPLUG_EN so this could only happen once, but
they new code restores those registers.  So just set those bits when
we set up the interrupt in the first place.

There is a regression from 2.6.34 related to the recent radeon power

item that's never been scheduled.  However, the code as is has some
other issues potentially leading to visible problems.

First, the mutex around cancel_delayed_work() in radeon_pm_suspend()
doesn't really serve any purpose, because cancel_delayed_work() only
tries to delete the work's timer.  Moreover, it doesn't prevent the
work handler from running, so the handler can do some wrong things if
it wins the race and in that case it will rearm itself to do some
more wrong things going forward.  So, I think it's better to wait for
the handler to return in case it's already been queued up for
execution.  Also, it should be prevented from rearming itself in that
case.

Second, in radeon_set_pm_method() the cancel_delayed_work() is not
sufficient to prevent the work handler from running and queing up
itself for the next run (the failure scenario is that
cancel_delayed_work() returns 0, so the handler is run, it waits on
the mutex and then rearms itself after the mutex has been released),
so again the work handler should be prevented from rearming itself in
that case..

Finally, there's a potential deadlock in radeon_pm_fini(), because
cancel_delayed_work_sync() is called under rdev->pm.mutex, but the
work handler tries to acquire the same mutex (if it wins the race).

Fix the issues described above.

Alex Deucher f892034a8c drm/radeon/kms/igp: fix possible divide by 0 in bandwidth code (v2)
Some IGP systems specify the system memory clock in the Firmware
table rather than the IGP info table.  Check both and make sure
we have a value system memory clock value.

v2: make sure rs690_pm_info is called on rs780/rs880 as well.

fixes a regression since 07d4190327b02ab3aaad25a2d168f79d92e8f8c2.

For some reason on resume, executing the BIOS scripts locks up the whole chipset, by avoiding the dynclk table the machine resumes properly and seems to function okay.

Jerome Glisse 46fcd2b3db drm/radeon/kms: Force HDP_NONSURF to maximum size
HDP non surface should cover the whole VRAM but we were misscomputing
the size and we endup in some case not covering the VRAM at all (if
VRAM size were > 1G). Covering more than the VRAM size shouldn't be
an issue.
