Issue:
In the scenario where svm_range_restore_pages is called, but
svm->checkpoint_ts has not been set and the retry fault has not been
drained, svm_range_unmap_from_cpu is triggered and calls svm_range_free.
Meanwhile, svm_range_restore_pages continues execution and reaches
svm_range_from_addr. This results in a "failed to find prange..." error,
causing the page recovery to fail.
How to fix:
Move the timestamp check code under the protection of svm->lock.
v2:
Make sure all right locks are released before go out.
v3:
Directly goto out_unlock_svms, and return -EAGAIN.
v4:
Refine code.

[Why]
If reset is detected and kfd need to evict working queues, HWS moving queue will be failed.
Then remaining queues are not evicted and in active state.
After reset done, kfd uses HWS to termination remaining activated queues but HWS is resetted.
So remove queue will be failed again.
[How]
Keep removing all queues even if HWS returns failed.
It will not affect cpsch as it checks reset_domain->sem.
v2: If any queue failed, evict queue returns error.
v3: Declare err inside the if-block.

[Why]
To avoid flickering during boot default brightness level set by BIOS
should be maintained for as much of the boot as feasible.
commit 2fe87f54abdc ("drm/amd/display: Set default brightness according
to ACPI") attempted to set the right levels for AC vs DC, but brightness
still got reset to maximum level in initialization code for
setup_backlight_device().
[How]
Remove the hardcoded initialization in setup_backlight_device() and
instead program brightness value to match BIOS (AC or DC). This avoids a
brightness flicker from kernel changing the value. Userspace may however
still change it during boot.

[Why]
It seems HPD interrupts are enabled by default for all connectors, even
if the hpd source isn't valid. An eDP for example, does not have a valid
hpd source (but does have a valid hpdrx source; see construct_phy()).
Thus, eDPs should have their hpd interrupt disabled.
In the past, this wasn't really an issue. Although the driver gets
interrupted, then acks by writing to hw registers, there weren't any
subscribed handlers that did anything meaningful (see
register_hpd_handlers()).
But things changed with the introduction of IPS. s2idle requires that
the driver allows IPS for DMUB fw to put hw to sleep. Since register
access requires hw to be awake, the driver will block IPS entry to do
so. And no IPS means no hw sleep during s2idle.
This was the observation on DCN35 systems with an eDP. During suspend,
the eDP toggled its hpd pin as part of the panel power down sequence.
The driver was then interrupted, and acked by writing to registers,
blocking IPS entry.
[How]
Since DC marks eDP connections as having invalid hpd sources (see
construct_phy()), DM should disable them at the hw level. Do so in
amdgpu_dm_hpd_init() by disabling all hpd ints first, then selectively
enabling ones for connectors that have valid hpd sources.

When userspace invokes S4 the flow is:
1) amdgpu_pmops_prepare()
2) amdgpu_pmops_freeze()
3) Create hibernation image
4) amdgpu_pmops_thaw()
5) Write out image to disk
6) Turn off system
Then on resume amdgpu_pmops_restore() is called.
This flow has a problem that because amdgpu_pmops_thaw() is called
it will call amdgpu_device_resume() which will resume all of the GPU.
This includes turning the display hardware back on and discovering
connectors again.
This is an unexpected experience for the display to turn back on.
Adjust the flow so that during the S4 sequence display hardware is
not turned back on.
