Felix Kuehling a2f14820e3 drm/amdgpu: Track pending retry faults in IH and VM (v2)
IH tracks pending retry faults in a hash table for fast lookup in
interrupt context. Each VM has a short FIFO of pending VM faults for
processing in a bottom half.

The IH prescreening stage adds retry faults and filters out repeated
retry interrupts to minimize the impact of interrupt storms.

It's the VM's responsibility remove pending faults once they are
handled. For now this is only done when the VM is destroyed.

v2:
- Made the hash table smaller and the FIFO longer. I never want the
  FIFO to fill up, because that would make prescreen take longer.
  128 pending page faults should be enough to keep migrations busy.

Felix Kuehling 5d86b2c391 drm/amd: Closed hash table with low overhead (v2)
This adds a statically sized closed hash table implementation with
low memory and CPU overhead. The API is inspired by kfifo.

Storing, retrieving and deleting data does not involve any dynamic
memory management, which makes it ideal for use in interrupt context.
Static memory usage per entry comprises a 32 or 64 bit hash key, two
bits for occupancy tracking and the value size stored in the table.
No list heads or pointers are needed. Therefore this data structure
should be quite cache-friendly, too.

It uses linear probing and lazy deletion. During lookups free space
is reclaimed and entries relocated to speed up future lookups.

If we see the seqno stop progressing, we abandon the test for fear that
the GPU died following the reset. However, during test teardown we still
wait for the GPU to idle before continuing, but we have already
confirmed that the GPU is dead. Furthermore, since we are inside a reset
test, we have disabled the hangchecker, and so there is no safety net and
we wait indefinitely. Detect the stuck GPU and declare it wedged as a

Uma Shankar aec0246f3e drm/i915: Enable scanline read based on frame timestamps
For certain platforms on certain encoders, timings are driven
from port instead of pipe. Thus, we can't rely on pipe scanline
registers to get the timing information. Some cases scanline
register read will not be functional.
This is causing vblank evasion logic to fail since it relies on
scanline, causing atomic update failure warnings.

This patch uses pipe framestamp and current timestamp registers
to calculate scanline. This is an indirect way to get the scanline.
It helps resolve atomic update failure for gen9 dsi platforms.

v2: Addressed Ville and Daniel's review comments. Updated the
register MACROs, handled race condition for register reads,
extracted timings from the hwmode. Removed the dependency on
crtc->config to get the encoder type.

v3: Made get scanline function generic

v4: Addressed Ville's review comments. Added a flag to decide timestamp
based scanline reporting. Changed 64bit variables to u32

v5: Adressed Ville's review comments. Put the scanline compute function
at the place of caller. Removed hwmode flags from uapi and used a local
i915 data structure instead.

v6: Used vblank hwmode to get the timings.

v7: Fixed sparse warnings, indentation and minor review comments.

v8: Limited this only for Gen9 DSI.

Ville Syrjälä 6b12ca569b drm/i915: Don't rmw PIPESTAT enable bits
i830 seems to occasionally forget the PIPESTAT enable bits when
we read the register. These aren't the only registers on i830 that
have problems with RMW, as reading the double buffered plane
registers returns the latched value rather than the last written
value. So something similar is perhaps going on with PIPESTAT.

This corruption results on vblank interrupts occasionally turning off
on their own, which leads to vblank timeouts and generally a stuck
display subsystem.

So let's not RMW the pipestat enable bits, and instead use the cached
copy we have around.

David Weinehall dff457d74e drm/i915: Speed up DMC firmware loading
Currently we're doing:

1. acquire lock
2. write word to hardware
3. release lock
4. repeat from 1

to load the DMC firmware. Due to the cost of acquiring/releasing a lock,
and the size of the DMC firmware, this slows down DMC loading a lot.

This patch simply acquires the lock, writes the entire firmware,
then releases the lock.  Testing shows resume speedups
in the order of 10ms on platforms with DMC firmware (GEN9+).

v2: Per feedback from Chris & Ville there's no need to do the whole
    forcewake dance, so lose that bit (Chris, Ville)

v3: Actually send the new version of the patch...

v4: Don't acquire the uncore lock. Disable preempt. (Chris)

Dhinakaran Pandiyan 3bc31a7f4d drm/i915/dp: Remove useless debug about TPS3 support
We already print training pattern used during link training and also

Both mst_disable_dp and mst_post_disable_dp print number of active links
before the variable has been updated. Move the print statement in
mst_disable_dp after the decrement so that the printed values indicate
the disabing of a mst connector. Also, add some text to clarify what we
are printing.
