There might be issue with lockup detection when scheduling on an
empty ring that have been sitting idle for a while. Thus update
the lockup tracking data when scheduling new work in an empty ring.

This fixes the kernel side so that the ring should come

UVD ring can't use scratch thus it does need writeback buffer to keep
a valid address or radeon_ring_backup will trigger a kernel fault.
It's ok to not unpin the write back buffer on suspend as it leave in
gtt and thus does not need eviction.
v2: Fix the uvd case.

If a buffer is never bound to a virtual memory pagetable than don't try
to unbind it. Only drawback is that we don't update the pagetable when
unbinding the ib pool buffer which is fine because it only happens at
suspend or module unload/shutdown.
Fixes spurious messages about buffers without VM mappings. E.g.:
radeon 0000:01:00.0: bo ffff88020afac400 don't has a mapping in vm ffff88021ca2b900

drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC
Egbert Eich fixed a long-standing bug where we simply used a
non-working i2c controller to read the EDID for SDVO-LVDS panels.
Unfortunately some machines seem to not be able to cope with the mode
provided in the EDID. Specifically they seem to not be able to cope
with a 4x pixel mutliplier instead of a 2x one, which seems to have
been worked around by slightly changing the panels native mode in the
VBT so that the dotclock is just barely above 50MHz.
Since it took forever to notice the breakage it's fairly safe to
assume that at least for SDVO-LVDS panels the VBT contains fairly sane
data. So just switch around the order and use VBT modes first.
v2: Also add EDID modes just in case, and spell Egbert correctly.
v3: Elaborate a bit more about what's going on on Chris' machine.

sdvo->hotplug_active is initialised during intel_sdvo_setup_outputs(),
and so we never enabled the hotplug interrupts on SDVO as we were
checking too early.
This regression has been introduced somewhere in the hpd rework for
the storm detection and handling starting with

DRM/I915: Add enum hpd_pin to intel_encoder.
and the follow-up patches to use the new encoder->hpd_pin variable for
the different irq setup functions.
The problem is that encoder->hpd_pin was set up _before_ the output
setup was done and so before we could assess the hotplug capabilities
of the outputs on an sdvo encoder.

A broken conditional would lead to SDVOC waiting upon hotplug events on
SDVOB - and so miss all activity on its SDVO port.

The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix
a memory leak where the framebuffer was released but not unpinned
properly. This patch only affects Cedarview.

Code refactoring in commit 8e9e3d2deacc460fbb8a4691140318f6e85e6891
(drm/nv84/disp: move hdmi control into core) disabled HDMI audio on my
nv84 by removing too much old code without adding it in the new one.
This patch adds the missing code within the new code layout resulting in
HDMI audio working again.
It should work on any HDMI head, but due to lacking ahrdware I could
only test the (1st) one.
It also might be possible that similar code is needed for nva3, which I
can't test.

In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used
for DDC. Thus the code will always have to rely on a LVDS panel
mode supplied by VBT.
In most cases this succeeds, so this didn't get detected for quite
a while.

If we always force the pipe A to on we can't use the hw state to
decide whether it should be on. Hence quirk the quirk.
The problem is that crtc->active tracks the state of the entire
display pipe, i.e. including planes, encoders and all. But our hw
state readout simply looks at the pipe. But with the pipe A quirk we
force-enable that (together with it's pll). To fix that mismatch we
have two options:
- Quirk the checked state to match what our sw tracking states if the
pipe A quirk is in effect.
- Improve the hw state readout to not get fooled by the pipe A quirk.
Since we already have similar state clamping in e.g. assert_pipe I've
opted for the first variant. Also note that we don't really loose any
state checking: Individual pieces of the abstract crtc pipe are
checked in the enable/disable functions with the various asssert_*
checks we have, and the hw state check code doesn't check anything if
the pipe is off anyway.
v2: Pimp commit message after discussion with Chris and only apply the
quirk for the quirk if we're checking pipe A. Otherwise we'll miss
state checking for pipe B on i830M ...
v3: Make the code comment consistent with the improved commit message,
too (Chris).

drm/i915: clear up wedged transitions
X can again get -EIO when it does not expect it. And even worse score
a SIGBUS when accessing gtt mmaps. The established ABI is that we
_only_ return an -EIO from execbuf - all other ioctls should just
work. And since the reset code moves all bos out of gpu domains and
clears out all the last_seqno/ring tracking there really shouldn't be
any reason for non-execbuf code to ever touch the hw and see an -EIO.
After some extensive discussions we've noticed that these spurios -EIO
are caused by i915_gem_wait_for_error:
http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg20540.html
That is easy to fix by returning 0 instead of -EIO, since grabbing the
dev->struct_mutex does not yet mean that we actually want to touch the
hw. And so there is no reason at all to fail with -EIO.
But that's not the entire since, since often (at least it's easily
googleable) dmesg indicates that the reset fails and we declare the
gpu wedged. Then, quite a bit later X wakes up with the "Timed out
waiting for the gpu reset to complete" DRM_ERROR message in
wait_for_errror and brings down the desktop with an -EIO/SIGBUS.
So clearly we're missing a wakeup somewhere, since the gpu reset just
doesn't take 10 seconds to complete. And indeed we're do handle the
terminally wedged state wrong.
Fix this all up.

When booting with DT, there's a crash when omapfb is probed. This is
caused by the fact that omapdss+DT is not yet supported, and thus
omapdss is not probed at all. On the other hand, omapfb is always
probed. When omapfb tries to use omapdss, there's a NULL pointer
dereference crash. The same error should most likely happen with omapdrm
and omap_vout also.
To fix this, add an "initialized" state to omapdss. When omapdss has
been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
check this state when they are probed to see that omapdss is actually
there.

The current radeon driver initialization routines, when using KMS, are written
so that the IRQ installation routine is called before initializing the WB buffer
and the CP rings. With some ASICs, though, the IRQ routine tries to access the
GFX_INDEX ring causing a call to RREG32 with the value of -1 in
radeon_fence_read. This, in turn causes the system to completely hang with some
cards, requiring a hard reset.
A call stack that can cause such a hang looks like this (using rv515 ASIC for the
example here):
* rv515_init (rv515.c)
* radeon_irq_kms_init (radeon_irq_kms.c)
* drm_irq_install (drm_irq.c)
* radeon_driver_irq_preinstall_kms (radeon_irq_kms.c)
* rs600_irq_process (rs600.c)
* radeon_fence_process - due to SW interrupt (radeon_fence.c)
* radeon_fence_read (radeon_fence.c)
* hang due to RREG32(-1)
The patch moves the IRQ installation to the card startup routine, after the ring
has been initialized, but before the IRQ has been set. This fixes the issue, but
requires a check to see if the IRQ is already installed, as is the case in the
system resume codepath.
I have tested the patch on three machines using the rv515, the rv770 and the
evergreen ASIC. They worked without issues.
This seems to be a known issue and has been reported on several bug tracking
sites by various distributions (see links below). Most of reports recommend
booting the system with KMS disabled and then enabling KMS by reloading the
radeon module. For some reason, this was indeed a usable workaround, however,
UMS is now deprecated and disabled by default.

When GPU acceleration is disabled, drm_vblank_cleanup() will free the
vblank-related data, such as vblank_refcount, vblank_inmodeset, etc.
But we found that drm_vblank_post_modeset() may be called after the
cleanup, which use vblank_refcount and vblank_inmodeset. And this will
cause a kernel panic.
Fix this by return immediately if dev->num_crtcs is zero. This is the
same thing that drm_vblank_pre_modeset() does.

radeon currently uses a drm function to get the speed capabilities for
the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard
method of performing this detection and this patch changes it to use
the max_bus_speed attribute.

This narrows the scope of the apple re-POST hack added in:
drm/radeon: re-POST the asic on Apple hardware when booted via EFI
That patch prevents UVD from working on macs when booted in EFI
mode. The original patch fixed macbook2,1 systems which were
r5xx and hence have no UVD. Limit the hack to those systems to
prevent UVD breakage on newer systems.

Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or
missing crtcs on certain asics.

Daniel writes:
A few fixes, nothing shocking:
- More Haswell pci ids. Includes a pile of marketing spare ids (which
despite the spare moniker show up all over the place).
- Fix a regression in handling modeset failures, resulting in black
screens on 3 pipe setups when we've run out of pch plls (Chris).
- Fix up the setcrtc semantics to unconditionally enable the outputs.
Juding from git digging that has (kinda) always been the case and neatly
fixes a few long-standing (i.e. forever) bug reports (Imre).
- jiffies_timeout + 1 patches from Imre. They partially fix spurious
wait_event failures in the interrupt-driven dp aux/i2c code. The other
part is a core patch for the wait_event macros going in through -mm. A
few patches more than strictly required since Imre is pushing for a
general solution in 3.11.

During DP AUX communication we might time out 1 jiffy too early, because
the calculated expiry jiffy value is one less than needed.
This is only one reason for false DP AUX timeouts. For a complete
solution we also need the following fix, which is now queued for
mainline: http://marc.info/?l=linux-kernel&m=136748515710837&w=2

At the moment wait_event_timeout/wait_event_interruptible_timeout may
time out 1 jiffy too early, as the calculated expiry time is 1 less than
needed. Besides timing out too early this also means that the
calculation of the remaining time will be incorrect and we will pass a
non-zero remaining time to user space in case of a time out. This is one
reason for the following bugzilla report:

We need this to avoid premature timeouts whenever scheduling a timeout

The following patches will take the helper into use.
Once the more generic solution proposed in the thread at [1] is accepted
this patch can be reverted while keeping the follow-up patches.
