The GGTT looks to be stored inside stolen memory on igpu which is not
treated as normal RAM. The core kernel skips this memory range when
creating the hibernation image, therefore when coming back from
hibernation the GGTT programming is lost. This seems to cause issues
with broken resume where GuC FW fails to load:
[drm] *ERROR* GT0: load failed: status = 0x400000A0, time = 10ms, freq = 1250MHz (req 1300MHz), done = -1
[drm] *ERROR* GT0: load failed: status: Reset = 0, BootROM = 0x50, UKernel = 0x00, MIA = 0x00, Auth = 0x01
[drm] *ERROR* GT0: firmware signature verification failed
[drm] *ERROR* CRITICAL: Xe has declared device 0000:00:02.0 as wedged.
Current GGTT users are kernel internal and tracked as pinned, so it
should be possible to hook into the existing save/restore logic that we
use for dgpu, where the actual evict is skipped but on restore we
importantly restore the GGTT programming. This has been confirmed to
fix hibernation on at least ADL and MTL, though likely all igpu
platforms are affected.
This also means we have a hole in our testing, where the existing s4
tests only really test the driver hooks, and don't go as far as actually
rebooting and restoring from the hibernation image and in turn powering
down RAM (and therefore losing the contents of stolen).

Although Bspec doesn't explicitly mentions that, as of Xe3_LPD, using
DMC wakelock is the officially recommended way of accessing registers
that would be off during DC5/DC6 and the legacy method (where the DMC
intercepts MMIO to wake up the hardware) is to be avoided.
As such, update the driver to use the DMC wakelock by default starting
with Xe3_LPD. Since the feature is somewhat new to the driver, also
allow disabling it via a module parameter for debugging purposes.
For that, make the existing parameter allow values -1 (per-chip
default), 0 (disabled) and 1 (enabled), similarly to what is done for
other parameters.
v2:
- Describe -1 in the same area where 0 and 1 are described. (Luca)

Enabling and disabling the DMC wakelock should be done as part of
enabling and disabling of dynamic DC states, respectively. We should not
enable or disable DMC wakelock independently of DC states, otherwise we
would risk ending up with an inconsistent state where dynamic DC states
are enabled and the DMC wakelock is disabled, going against current
recommendations and making MMIO transactions potentially slower. In
future display IPs that could have a worse outcome if DMC trap
implementation is completely removed.
So, let's make things safer by tying stuff together, removing the
independent calls, and also put warnings in place to detect inconsistent
calls.

It is possible that there are active wakelock references at the time we
are disabling the DMC wakelock mechanism. We need to deal with that in
two ways:
(A) Implement the missing step from Bspec:
The Bspec instructs us to clear any existing wakelock request bit
after disabling the mechanism. That gives a clue that it is okay to
disable while there are locks held and we do not need to wait for
them. However, since the spec is not explicit about it, we need
still to get confirmation with the hardware team. Let's thus
implement the spec and add a TODO note.
(B) Ensure a consistent driver state:
The enable/disable logic would be problematic if the following
sequence of events would happen:
1. Function A calls intel_dmc_wl_get();
2. Some function calls intel_dmc_wl_disable();
3. Some function calls intel_dmc_wl_enable();
4. Function A is done and calls intel_dmc_wl_put().
At (2), the refcount becomes zero and then (4) causes an invalid
decrement to the refcount. That would cause some issues:
- At the time between (3) and (4), function A would think that
the hardware lock is held but it could not be really held
until intel_dmc_wl_get() is called by something else.
- The call made to (4) could cause the refcount to become zero
and consequently the hardware lock to be released while there
could be innocent paths trusting they still have the lock.
To fix that, we need to keep the refcount correctly in sync with
intel_dmc_wl_{get,put}() calls and retake the hardware lock when
enabling the DMC wakelock with a non-zero refcount.
One missing piece left to be handled here is the following scenario:
1. Function A calls intel_dmc_wl_get();
2. Some function calls intel_dmc_wl_disable();
3. Some function calls intel_dmc_wl_enable();
4. Concurrently with (3), function A performs the MMIO in between
setting DMC_WAKELOCK_CFG_ENABLE and asserting the lock with
__intel_dmc_wl_take().
I'm mostly sure this would cause issues future display IPs if DMC
trap implementation was completely removed. We need to check with
the hardware team whether it would be safe to assert the hardware
lock before setting DMC_WAKELOCK_CFG_ENABLE to avoid this scenario.
If not, then we would have to deal with that via software
synchronization.

When the DMC wakelock refcount reaches zero, we know that there are no
users and that we can do the actual release operation on the hardware,
which is queued with a delayed work. The idea of the delayed work is to
avoid performing the release if a new lock user appears (i.e. refcount
gets incremented) in a very short period of time.
Based on the above, the release work should bail out if refcount is
non-zero (meaning new lock users appeared in the meantime), but our
current code actually does the opposite: it bails when refcount is zero.
That means that the wakelock is not released when it should be; and
that, when the work is not canceled in time, it ends up being releasing
when it should not.
Fix that by inverting the condition.

In upcoming display changes, we will modify the DMC wakelock MMIO
waiting code to choose a non-sleeping variant implementation, because
the wakelock is also taking in atomic context.
While xe provides an explicit parameter (namely "atomic") to prevent
xe_mmio_wait32() from sleeping, i915 does not and implements that
behavior when slow_timeout_ms is zero.
So, for now, let's mimic what i915 does to allow for display to use
non-sleeping MMIO wait. In the future, we should come up with a better
and explicit interface for this behavior in i915, at least while display
code is not an independent entity with proper interfaces between xe and
i915.

__intel_wait_for_register() more explanatory than a FIXME-like text.

For example, full adapter reset (mode1/mode2/BACO/etc),
soft reset, queue reset, and pipe reset.
V2: the sysfs node returns a text string instead of some flags (Christian)
v3: add a generic helper which takes the ring as parameter
and print the strings in the order they are applied (Christian)
check amdgpu_gpu_recovery before creating sysfs file itself,
and initialize supported_reset_types in IP version files (Lijo)

Reset sequence indicates that hardware already ran into a bad state.
Avoid sending unmap queue request to reset KCQ. This will also cover RAS
error scenarios which need a reset to recover, hence remove the check.

In current logic, it calls ring_alloc followed by a ring_test. ring_test
in turn will call another ring_alloc. This is illegal usage as a
ring_alloc is expected to be closed properly with a ring_commit. Change
to commit the map/unmap queue packet first followed by a ring_test. Add a
comment about the usage of ring_test.
Also, reorder the current pre-condition checks of job hang or kiq ring
scheduler not ready. Without them being met, it is not useful to attempt
ring or memory allocations.
Fixes tag refers to the original patch which introduced this issue which
then got carried over into newer code.

mes.
The currect code use the address "adev->mes.read_val_ptr" to
store the value read from register via mes.
So when multiple threads read register,
multiple threads have to share the one address,
and overwrite the value each other.
Assign an address by "amdgpu_device_wb_get" to store register value.
each thread will has an address to store register value.

Local values of scheduling priorities need to be adjusted when
changing the schedule_if_idle policy as those are related.
Disabling schedule_if_idle policy forces the low priority, and
enabling schedule_if_idle policy forces the normal priority.
