[PATCH] drm/amd/display: reset the workload type when using MALL

[Kenneth Feng]

Reset the workload type when using MALL.
When there is no activity on the screen, dal requestes dmcub
to use MALL. However, gfx ring is not empty at the same time.
Currrently the workload type is set to 3D fullscreen when gfx
ring has jobs. No activity on the screen and the gfx ring empty
state can not be synchronized to each other. By removing the
3D fullscreen workload when there is no activity on screen, the
event can be passed down to dmcub->pmfw, since pmfw only allows
MALL when the workload type setting is bootup default, then MALL
can be really used. And this does not impact the thread to detect
the ring jobs and can set back to the 3D fullscreen later.

I double checked all of the places that check in_s4 and I'm reasonably
sure moving this around won't break anything.  It looks like we only
really are about it on the suspend/fini side.

Thanks for catch up and fix this race condition. It looks good to me. 
One minor thing below:


On 3/6/2025 12:03 AM, Emily Deng wrote:

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.

We drop page fault because it is stale, not mean to handle it again. 
if return -EAGAIN we do amdgpu_gmc_filter_faults_remove. If after 
unmap, user map same range again we should treat page fault happened 
at same range as new one.

Xiaogang

Sorry, I didn't quite catch that. So, you think we shouldn't 
remove the fault from amdgpu_gmc_filter_faults_remove?


I think return "-EAGAIN" means a page fault with an addr and a pasid is 
not handled this time. Same page fault will come back again and kfd will 
handle it, so remove it from filter to make sure it will be handled next 
time.


In this case this page fault is stale and we do not need or cannot 
handle it. There is no indication it will come back again and we need 
handle it.  I am not sure if should remove it from filter. I just 
concern if should return "-EAGAIN" in this case.

I think for now we can ignore the kernel caps in Mesa for these codecs as the 
maximum size is the same for all asics. We can later switch to kernel caps 
again, no need to bump the version just for this.

[PATCH] drm/amdgpu: deprecate guilty handling

[Christian König]

The guilty handling tried to establish a second way of signaling problems with
the GPU back to userspace. This caused quite a bunch of issue we had to work
around, especially lifetime issues with the drm_sched_entity.

Just drop the handling altogether and use the dma_fence based approach instead.

[PATCH V3 00/11] Add disable kernel queue support

[Alex Deucher]

To better evaluate user queues, add a module parameter
to disable kernel queues.  With this set kernel queues
are disabled and only user queues are available.  This
frees up hardware resources for use in user queues which
would otherwise be used by kernel queues and provides
a way to validate user queues without the presence
of kernel queues.

v2: use num_gfx_rings and num_compute_rings per
Felix suggestion
v3: include num_gfx_rings fix in amdgpu_gfx.c

Alex Deucher (11):
  drm/amdgpu: add parameter to disable kernel queues
  drm/amdgpu: add ring flag for no user submissions
  drm/amdgpu/gfx: add generic handling for disable_kq
  drm/amdgpu/mes: centralize gfx_hqd mask management
  drm/amdgpu/mes: update hqd masks when disable_kq is set
  drm/amdgpu/mes: make more vmids available when disable_kq=1
  drm/amdgpu/gfx11: add support for disable_kq
  drm/amdgpu/gfx12: add support for disable_kq
  drm/amdgpu/sdma: add flag for tracking disable_kq
  drm/amdgpu/sdma6: add support for disable_kq

[PATCH 09/11] drm/amdgpu/sdma: add flag for tracking disable_kq

[Alex Deucher]

For SDMA, we still need kernel queues for paging so
they need to be initialized, but we no not want to
accept submissions from userspace when disable_kq
is set.

I don't think it's a good idea for DM to explicitly switch
power profiles.

Generally the display driver interacts with PM in
two ways:
- indicate min clocks that are needed for real-time operation
  of DCN
- allow various state switches when the driver knows they
  won't impact real-time operation of DCN

Just wanted to drop my "I like this" on your series here. Short

I think this will break for chips with harvested DCN blocks.  I think
you need to return early here in that case.  E.g.,

if (adev->harvest_ip_mask & AMD_HARVEST_IP_DMU_MASK)
return 0;

Tested on top of amd-drm-next branch and 6.11.11 on 3 different devices.
It fixes all of them. 

It should be included in recent LTS kernels at least.

To keep this balanced, you should get a reference when we disable the
optimizations.  Also if ROCm applications are running, the compute
profile will be active so that should be decremented too or if VCN
jobs are running the video profile may be active as well.  On the
other hand, if users have apps running when the display is off, maybe
they don't want the idle optimizations in the first place.
Alternatively, we could have a suspend/resume workload profile
function that sets a flag in sw_smu which sets the default workload
profile and skips all updates to the workload profile while that flag
is set.  The swsmu will still track the ref counts and then when we
resume the workload profile handling, we can restore all of the
workloads profiles based on the ref counts.

[PATCH 6/8] drm/amdgpu: stop reserving VMIDs to enforce isolation

[Christian König]

That was quite troublesome for gang submit. Completely drop this
approach and enforce the isolation separately.

[PATCH 2/8] drm/amdgpu: use GFP_NOWAIT for memory allocations

[Christian König]

In the critical submission path memory allocations can't wait for
reclaim since that can potentially wait for submissions to finish.

Finally clean that up and mark most memory allocations in the critical
path with GFP_NOWAIT. The only exception left is the dma_fence_array()
used when no VMID is available, but that will be cleaned up later on.

[PATCH 4/8] drm/amdgpu: rework how isolation is enforced v2

[Christian König]

Limiting the number of available VMIDs to enforce isolation causes some
issues with gang submit and applying certain HW workarounds which
require multiple VMIDs to work correctly.

So instead start to track all submissions to the relevant engines in a
per partition data structure and use the dma_fences of the submissions
to enforce isolation similar to what a VMID limit does.

v2: use ~0l for jobs without isolation to distinct it from kernel
submissions which uses NULL for the owner. Add some warning when we
are OOM.

[PATCH 5/8] drm/amdgpu: rework how the cleaner shader is emitted v3

[Christian König]

Instead of emitting the cleaner shader for every job which has the
enforce_isolation flag set only emit it for the first submission from
every client.

v2: add missing NULL check
v3: fix another NULL pointer deref

That will completely break suspend/resume on laptops.

we essentially need to always check if a BO can fit into GTT.

No it isn't. On suspend the power to VRAM is turned off and so we always need 
to be able to evacuate buffers into GTT.

[PATCH] drm/amdgpu: Allow buffers that don't fit GTT into VRAM

[Natalie Vock]

When userspace requests buffers to be placed into GTT | VRAM, it is
requesting the buffer to be placed into either of these domains. If the
buffer fits into VRAM but does not fit into GTT, then let the buffer
reside in VRAM instead of failing allocation entirely.

This originally came up in 
https://gitlab.freedesktop.org/mesa/mesa/-/issues/12713:
The crux of the issue is that some applications expect they can allocate
buffers up to the size of VRAM - however, some setups have a
smaller-than-VRAM GTT region. RADV always sets VRAM | GTT for all buffer
allocations, so this causes amdgpu to reject the allocation entirely
because it cannot fit into GTT, even though it could fit into VRAM.

In my opinion, this check doesn't make sense: It is completely valid
behavior for the kernel to always keep a VRAM | GTT buffer in VRAM.
The only case where buffers larger than the GTT size are special is that
they cannot be evicted to GTT (or swapped out), but the kernel already
allows VRAM-only buffers to be larger than GTT, and those cannot be
swapped out either. With the check removed, VRAM | GTT buffers larger
than GTT behave exactly like VRAM-only buffers larger than GTT.

The patch adding this check seems to have added it in a v2 - however I
was unable to find any public discussion around the patch with reasoning
in favor of this check.

[PATCH v2] drm/amd/amdkfd: Evict all queues even HWS remove queue failed

[Yifan Zha]

[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.

Re: [PATCH] drm/amd/amdkfd: Evict all queues even HWS remove queue failed

[Zha, YiFan(Even)]

[AMD Official Use Only - AMD Internal Distribution Only]

Hi Felix,

Thanks. Patch v2 is submitted. It should make sure error returned even if 
remove_queue_mes is success.

Could you pleas help to review it again?


Thanks.



Best regard,

Is every subsequent call to remove_queue_mes guaranteed to also return
an error? If not, you need a way to make sure an error is returned if
any queue failed to be removed even if the last queue succeeded.

[PATCH RFC v3 1/7] drm/display: dp: implement new access helpers

[Dmitry Baryshkov]

From: Dmitry Baryshkov 

Existing DPCD access functions return an error code or the number of
bytes being read / write in case of partial access. However a lot of
drivers either (incorrectly) ignore partial access or mishandle error
codes. In other cases this results in a boilerplate code which compares
returned value with the size.

Implement new set of DPCD access helpers, which ignore partial access,
always return 0 or an error code.

[PATCH] drm/amdgpu: add UAPI for workload profile to ctx interface

[Alex Deucher]

Allow a rendering context to set a workload profile.  This
allows an application to select a workload profile to match
its intended use case.  Each rendering context can set a
profile and internally the SMU firmware will select the highest
priority profile among those that are active.  When the
context is destroyed, the profile is automatically cleaned up.

E.g., a compositor can select the fullscreen3d hint when it
unredirects a fullscreen game.  This hint tweaks allows the
driver to tweak the performance for a specific workload associated
with the rendering context.

Initial proposed userspace:
https://gitlab.freedesktop.org/monado/monado/-/merge_requests/2371

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3802

[PATCH 07/11] drm/amdgpu/gfx11: add support for disable_kq

[Alex Deucher]

Plumb in support for disabling kernel queues in
GFX11.  We have to bring up a GFX queue briefly in
order to initialize the clear state.  After that
we can disable it.

v2: use ring counts per Felix' suggestion

Re: [PATCH v2] drm/amd/amdkfd: Evict all queues even HWS remove queue failed

[Felix Kuehling]

On 2025-03-07 03:53, Yifan Zha wrote:

[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.

You should still initialize retval to 0, otherwise the function may 
return an uninitialized value if there are no MES queues. err does not 
need to be initialized because you're always assigning a value just 
before checking it below.


In fact, you could declare err inside the if-block below, since it is 
only needed in that scope. It is preferred to declare variables in a 
more limited scope if they are not needed outside.
