drm/amdgpu: Add reset control handling to reset workflow

This prefers reset control based handling if it's implemented
for a particular ASIC. If not, it takes the legacy path. It uses
the legacy method of preparing environment (job, scheduler tasks)
and restoring environment.

v2: remove unused variable (Alex)

drm/amdgpu: Add reset control to amdgpu_device

v1: Add generic amdgpu_reset_control to handle different types of resets. It
may be added at device, hive or ip level. Each reset control has a list
of handlers associated with it to handle different types of reset. Reset
control is responsible for choosing the right handler given a particular
reset context.

Handler objects may implement a set of functions on how to handle a
particular type of reset.

prepare_env = Prepare environment/software context (not used currently).
prepare_hwcontext = Prepare hardware context for the reset.
perform_reset = Perform the type of reset.
restore_hwcontext = Restore the hw context after reset.
restore_env = Restore the environment after reset (not used currently).

Reset context carries the context of reset, as of now this is based on
the parameters used for current set of resets.

drm/amd/amdgpu implement tdr advanced mode

[Why]
Previous tdr design treats the first job in job_timeout as the bad job.
But sometimes a later bad compute job can block a good gfx job and
cause an unexpected gfx job timeout because gfx and compute ring share
internal GC HW mutually.

[How]
This patch implements an advanced tdr mode.It involves an additinal
synchronous pre-resubmit step(Step0 Resubmit) before normal resubmit
step in order to find the real bad job.

1. At Step0 Resubmit stage, it synchronously submits and pends for the
first job being signaled. If it gets timeout, we identify it as guilty
and do hw reset. After that, we would do the normal resubmit step to
resubmit left jobs.

2. For whole gpu reset(vram lost), do resubmit as the old way.

drm/amd/display: check fb of primary plane

Sometimes the primary plane might not be initialized (yet), which
causes dm_check_crtc_cursor to divide by zero.
Apparently a weird state before a S3-suspend causes the aforementioned
divide-by-zero error when resuming from S3. This was explained in
bug 212293 on Bugzilla.

To avoid this divide-by-zero error we check if the primary plane's fb
isn't NULL. If it's NULL the src_w and src_h attributes will be 0,
which would cause a divide-by-zero.

This fixes Bugzilla report 212293

Remove per_device_list from kfd_process and replace it with a
kfd_process_device pointers array of MAX_GPU_INSTANCES size. This helps
to manage the kfd_process_devices binded to a specific kfd_process.
Also, functions used by kfd_chardev to iterate over the list were
removed, since they are not valid anymore. Instead, it was replaced by a
local loop iterating the array.

drm/amd/display: Fix UBSAN: shift-out-of-bounds warning

[Why]
On NAVI14 CONFIG_UBSAN reported shift-out-of-bounds at
display_rq_dlg_calc_20v2.c:304:38

rq_param->misc.rq_c.blk256_height is 0 when chroma(*_c) is invalid.
dml_log2 returns -1023 for log2(0), although log2(0) is undefined.

Which ended up as:
rq_param->dlg.rq_c.swath_height = 1 << -1023

[How]
Fix applied on all dml versions.
1. Ensure dml_log2 is only called if the argument is greater than 0.
2. Subtract req128_l/req128_c from log2_swath_height_l/log2_swath_height_c
only when it is greater than 0.

[Why]

drm/amd/pm: fix Navi1x runtime resume failure V2

The RLC was put into a wrong state on runtime suspend. Thus the RLC
autoload will fail on the succeeding runtime resume. By adding an
intermediate PPSMC_MSG_PrepareMp1ForUnload(some GC hard reset involved,
designed for PnP), we can bring RLC back into the desired state.

V2: integrate INTERRUPTS_ENABLED flag clearing into current
mp1 state set routines

Not needed as the device is in gfxoff state so the CG/PG state

as per:
https://www.kernel.org/doc/html/latest/driver-api/pm/devices.html

The prepare callback is required to support the DPM_FLAG_SMART_SUSPEND
driver flag. This allows runtime pm to auto complete when the
system goes into suspend avoiding a wake up on suspend and on resume.
Apply this for hybrid gfx and BOCO systems where d3cold is
provided by the ACPI platform.
