Use HOTPLUG_INT_STATUS_G4X instead of HOTPLUG_INT_STATUS_I915 on VLV/CHV
so that we don't confuse the AUX status bits with SDVO status bits.
Avoid pointless log spam as below while handling AUX interrupts:
[drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000
[drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000

[drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x71450064
Note that there's no functional issue, it's just that the sdvo bits
overlap with the dp aux bits. Hence every time we receive an aux
interrupt we also think there's an sdvo hpd interrupt, but due to lack
of any sdvo encoders nothing ever happens because of that.

As we perform the mmio-flip without any locking and then try to acquire
the struct_mutex prior to dereferencing the request, it is possible for
userspace to queue a new pageflip before the worker can finish clearing

is that the new flip could be completed before the GPU has finished

This patch adds a new kernel module parameter to amdkfd,
called send_sigterm.
This parameter specifies whether amdkfd should send the
SIGTERM signal to an HSA process, when the following conditions
occur:
1. The GPU triggers an exception regarding a kernel that was
issued by this process.
2. The HSA process isn't waiting on an event that handles
this exception.
The default behavior is not to send a SIGTERM and suffice
with a dmesg error print.

This patch adds the interrupt handling module, kfd_interrupt.c, and its
related members in different data structures to the amdkfd driver.
The amdkfd interrupt module maintains an internal interrupt ring
per amdkfd device. The internal interrupt ring contains interrupts
that needs further handling. The extra handling is deferred to
a later time through a workqueue.
There's no acknowledgment for the interrupts we use. The hardware
simply queues a new interrupt each time without waiting.
The fixed-size internal queue means that it's possible for us to lose
interrupts because we have no back-pressure to the hardware.
However, only interrupts that are "wanted" by amdkfd, are copied into
the amdkfd s/w interrupt ring, in order to minimize the chances
for overflow of the ring.

Drivers may need to store the state of shared resources, such as PLLs
or FIFO space, into the atomic state. Allow this by making it possible
to subclass drm_atomic_state.
Changes since v1:
- Change member names for functions to atomic_state_(alloc,clear)
- Change __drm_atomic_state_new to drm_atomic_state_init
- Allow free function to be overridden too, in case extra memory is
allocated in alloc.
Changes since v2:
- Rename *_default_free to default_release, to make clear it doesn't
free the state object itself.

Currently we're adding CEA modes after the inferred modes, which means
we might get multiple modes that are very close to each other, but
slightly different, which seems a bit silly. That's because duplicate
mode check that occurs when adding inferred modes would not consider
CEA modes as potential duplicates. Reverse the order so that CEA
modes get added before inferred modes, and are thus considered potential
duplicates.

This patch fixes a timing issue that causes a GPU hang when the system
comes out of power saving.
During pm_resume, We are submitting batchbuffers before enabling
Interrupts this is causing us to miss the context switch interrupt,
and in consequence intel_execlists_handle_ctx_events is not triggered.
This patch is based on a patch from Deepak S <deepak.s@intel.com>
from another platform.
The patch fixes an issue introduced by:
commit e7778be1ea
drm/i915: Fix startup failure in LRC mode after recent init changes
The above patch added a call to init_context() to fix an issue introduced
by a previous patch. But, it then opened up a small timing window for the
batches being added by the init_context (basically setting up the context)
to complete before the interrupts have been turned on, thus hanging the
GPU.

Since commit 844b03f277 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

Sometimes (exactly when is a bit unclear) DISPLAY_PHY_CONTROL appears to
get corrupted. The values I've managed to read from it seem to have some
pattern but vary quite a lot. The corruption doesn't seem to just happen
when the register is accessed, but can also happen spontaneosly during
modeset. When this happens during a modeset things go south and the
display doesn't light up.
I've managed to hit the problemn when toggling HDMI on port D on and
off. When things get corrupted the display doesn't light up, but as soon
as I manually write the correct value to the register the display comes
up.
First I was suspicious that we ourselves accidentally overwrite it with
garbage, but didn't catch anything with the reg_rw tracepoint. Also I
sprinkled check all over the modeset path to see exactly when the
corruption happens, and eg. the read back value was fine just before
intel_dp_set_m(), and corrupted immediately after it. I also made my
check function repair the register value whenever it was wrong, and with
this approach the corruption repeated several times during the modeset
operation, always seeming to trigger in the same exact calls to the
check function, while other calls to the function never caught anything.
So far I've not seen this problem occurring when carefully avoiding all
read accesses to DISPLAY_PHY_CONTROL. Not sure if that's just pure luck
or an actual workaround, but we can hope it works. So let's avoid reading
the register and instead track the desired value of the register in dev_priv.
