Arindam Nath b0b00ff16f drm/amd/amdgpu: enable clockgating only after late init
Sometimes during multiple reboots, the system hangs
during bootup. The issue is very random and happens
once in around 50 reboots or so.

It seems if clockgating is enabled before late init,
the GFX engine sometimes does not respond.

This patch changes the ordering a little so that
both powergating and clockgating are enabled only
after late init calls.

Marek Olšák 95844d20ae drm/amdgpu: throttle buffer migrations at CS using a fixed MBps limit (v2)
The old mechanism used a per-submission limit that didn't take previous
submissions within the same time frame into account. It also filled VRAM
slowly when VRAM usage dropped due to a big eviction or buffer deallocation.

This new method establishes a configurable MBps limit that is obeyed when
VRAM usage is very high. When VRAM usage is not very high, it gives
the driver the freedom to fill it quickly. The result is more consistent
performance.

It can't keep the BO move rate low if lots of evictions are happening due
to VRAM fragmentation, or if a big buffer is being migrated.

The amdgpu.moverate parameter can be used to set a non-default limit.
Measurements can be done to find out which amdgpu.moverate setting gives
the best results.

Mainly APUs and cards with small VRAM will benefit from this. For F1 2015,
anything with 2 GB VRAM or less will benefit.

Some benchmark results - F1 2015 (Tonga 2GB):

Limit      MinFPS AvgFPS
Old code:  14     32.6
128 MB/s:  28     41
64 MB/s:   15.5   43
32 MB/s:   28.7   43.4
8 MB/s:    27.8   44.4
8 MB/s:    21.9   42.8 (different run)

Random drops in Min FPS can still occur (due to fragmented VRAM?), but
the average FPS is much better. 8 MB/s is probably a good limit for this
game & the current VRAM management. The random FPS drops are still to be
tackled.

Emily Deng a6be757051 drm/amdgpu: Set ip_blocks according variable amdgpu_virtual_display.
For virtual display feature, if user set the option "amdgpu.virtual_display=1"
when load amdgpu.ko. Then need to set the ip_blocks with virtual display ip
blocks. And when enable virtual display, the amdgpu_dal need to be set to zero.

Lyude 23a1a9e54e drm/amdgpu: Disable RPM helpers while reprobing connectors on resume
Just about all of amdgpu's connector probing functions try to acquire
runtime PM refs. If we try to do this in the context of
amdgpu_resume_kms by calling drm_helper_hpd_irq_event(), we end up
deadlocking the system.

Since we're guaranteed to be holding the spinlock for RPM in
amdgpu_resume_kms, and we already know the GPU is in working order, we
need to prevent the RPM helpers from trying to run during the initial
connector reprobe on resume.

There's a couple of solutions I've explored for fixing this, but this
one by far seems to be the simplest and most reliable (plus I'm pretty
sure that's what disable_depth is there for anyway).

Reproduction recipe:
  - Get any laptop dual GPUs using PRIME
  - Make sure runtime PM is enabled for amdgpu
  - Boot the machine
  - If the machine managed to boot without hanging, switch out of X to
    another VT. This should definitely cause X to hang infinitely.

Changes since v1:
  - add appropriate #ifdef checks for CONFIG_PM. This is not very
    useful, but it appears some kernel test suites test compiling amdgpu
    with CONFIG_PM disabled, which results in this patch breaking the builds
    if we don't include this #ifdef
