ee52489d12 drm/amdgpu: Place NPS mode request on unload
If a user has requested NPS mode switch, place the request through PSP
during unload of the driver. For devices which are part of a hive, all
requests are placed together. If one of them fails, revert back to the
current NPS mode.

b472b8d829 drm/amd: Taint the kernel when enabling overdrive
Some distributions have been patching amdgpu to enable overdrive by
default which may compromise stability.  Furthermore when bug reports
are brought upstream it's not obvious that the system has been tampered
with.

When overdrive is enabled taint the kernel and leave a critical message
in the logs for users so that it's obvious in a bug report it's been
tampered with.

f679fd6057 drm/amdgpu: Init zone device and drm client after mode-1 reset on reload
In passthrough environment, when amdgpu is reloaded after unload, mode-1
is triggered after initializing the necessary IPs, That init does not
include KFD, and KFD init waits until the reset is completed. KFD init
is called in the reset handler, but in this case, the zone device and
drm client is not initialized, causing app to create kernel panic.

v2: Removing the init KFD condition from amdgpu_amdkfd_drm_client_create.
As the previous version has the potential of creating DRM client twice.

v3: v2 patch results in SDMA engine hung as DRM open causes VM clear to SDMA
before SDMA init. Adding the condition to in drm client creation, on top of v1,
to guard against drm client creation call multiple times.

Currently, if the abmlevel module parameter is set, it is possible for
user space to override the ABM level at some point after boot. However,
that is undesirable because it means that we aren't respecting the

prevent user space from changing the ABM level if the module parameter
is set to a non-auto value.

087a3e13ec drm/amdgpu: revert "Adjust removal control flow for smu v13_0_2"
Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the
HW in an active state and is an unbalanced use of the IP callbacks.

Using the IP callbacks like this can lead to memory leaks, double
free and imbalanced reference counters.

Leaving the HW in an active state can lead to DMA accesses to memory now
freed by the driver.

Both is a complete no-go for driver unload so completely revert the
workaround for now.

bd1f6a31e7 drm/amd: Enable PCIe PME from D3
When dGPU is put into BOCO it may be in D3cold but still able send
PME on display hotplug event. For this to work it must be enabled
as wake source from D3.

When runpm is enabled use pci_wake_from_d3() to mark wakeup as
enabled by default.

6ba5b61383 drm/amdgpu: add a module parameter to control the AGP aperture
Add a module parameter to control the AGP aperture.  The AGP
aperture is an aperture in the GPU's internal address space
which provides direct non-paged access to the platform address
space.  This access is non-snooped so only uncached memory
can be accessed.

Add a knob so that we can toggle this for debugging.

5095d54181 drm/amd: Evict resources during PM ops prepare() callback
Linux PM core has a prepare() callback run before suspend.

If the system is under high memory pressure, the resources may need
to be evicted into swap instead.  If the storage backing for swap
is offlined during the suspend() step then such a call may fail.

So move this step into prepare() to move evict majority of
resources and update all non-pmops callers to call the same callback.

4d6fc55ab1 drm/amdgpu: expand runpm parameter
Allow the user to specify -2 as auto enabled with displays.

By default we don't enter runtime suspend when there are
displays attached because it does not work well in some
desktop environments due to the driver sending hotplug
events on resume in case any new displays were attached
while the GPU was powered down.  Some users still want
this functionality though, so this lets you enable it.
