2024-07-25drm/scheduler: remove full_recover from drm_sched_startChristian König12-31/+22
This was basically just another one of amdgpus hacks. The parameter allowed to restart the scheduler without turning fence signaling on again. That this is absolutely not a good idea should be obvious by now since the fences will then just sit there and never signal. While at it cleanup the code a bit.

2024-07-24drm/amdgpu: reset vm state machine after gpu reset(vram lost)ZhenGuo Yin1-4/+5
[Why] Page table of compute VM in the VRAM will lost after gpu reset. VRAM won't be restored since compute VM has no shadows. [How] Use higher 32-bit of vm->generation to record a vram_lost_counter. Reset the VM state machine when vm->genertaion is not equal to the new generation token. v2: Check vm->generation instead of calling drm_sched_entity_error in amdgpu_vm_validate. v3: Use new generation token instead of vram_lost_counter for check.

In the DML math_ceil2 function, there is one ASSERT if the significance is equal to zero. However, significance might be equal to zero sometimes, and this is not an issue for a ceil function, but the current ASSERT will trigger warnings in those cases. This commit removes the ASSERT if the significance is equal to zero to avoid unnecessary noise.

2024-07-24drm/amdgpu/sdma5.2: Update wptr registers as well as doorbellAlex Deucher1-0/+12
We seem to have a case where SDMA will sometimes miss a doorbell if GFX is entering the powergating state when the doorbell comes in. To workaround this, we can update the wptr via MMIO, however, this is only safe because we disallow gfxoff in begin_ring() for SDMA 5.2 and then allow it again in end_ring(). Enable this workaround while we are root causing the issue with the HW team.

2024-07-23drm/i915/gt: Do not consider preemption during execlists_dequeue for gen8Nitin Gote1-5/+1
We're seeing a GPU hang issue on a CHV platform, which was caused by commit bac24f59f454 ("drm/i915/execlists: Enable coarse preemption boundaries for Gen8"). The Gen8 platform only supports timeslicing and doesn't have a preemption mechanism, as its engines do not have a preemption timer. Commit 751f82b353a6 ("drm/i915/gt: Only disable preemption on Gen8 render engines") addressed this issue only for render engines. This patch extends that fix by ensuring that preemption is not considered for all engines on Gen8 platforms. v4: - Use the correct Fixes tag (Rodrigo Vivi) - Reworded commit log (Andi Shyti) v3: - Inside need_preempt(), condition of can_preempt() is not required as simplified can_preempt() is enough.

2024-07-23drm/ttm: Allow direct reclaim to allocate local memory v2Rajneesh Bhardwaj1-1/+1
Limiting the allocation of higher order pages to the closest NUMA node and enabling direct memory reclaim provides not only failsafe against situations when memory becomes too much fragmented and the allocator is not able to satisfy the request from the local node but falls back to remote pages (HUGEPAGE) but also offers performance improvement. Accessing remote pages suffers due to bandwidth limitations and could be avoided if memory becomes defragmented and in most cases without using manual compaction. (/proc/sys/vm/compact_memory) Note: On certain distros such as RHEL, the proactive compaction is disabled.

2024-07-22drm/nouveau: use GEM references instead of TTMsDanilo Krummrich9-40/+44
TTM wants to get rid of the duplicate refcounting of the embedded GEM object and its own reference count. Hence, use of GEM object references where possible. Also get rid of nouveau_bo_ref() and replace it with nouveau_bo_fini(), which drops the initial reference we get from initializing a ttm_bo.

2024-07-22drm/panel: Avoid warnings w/ panel-simple/panel-edp at shutdownDouglas Anderson4-37/+68
At shutdown if you've got a _properly_ coded DRM modeset driver then you'll get these two warnings at shutdown time: Skipping disable of already disabled panel Skipping unprepare of already unprepared panel These warnings are ugly and sound concerning, but they're actually a sign of a properly working system. That's not great. We're not ready to get rid of the calls to drm_panel_disable() and drm_panel_unprepare() because we're not 100% convinced that all DRM modeset drivers are properly calling drm_atomic_helper_shutdown() or drm_helper_force_disable_all() at the right times. However, having the warning show up for correctly working systems is bad. As a bit of a workaround, add some "if" tests to try to avoid the warning on correctly working systems. Also add some comments and update the TODO items in the hopes that future developers won't be too confused by what's going on here.

The Samsung ATNA45AF01 panel is an AMOLED eDP panel that has backlight control over the DP AUX channel. While it works almost correctly with the generic "edp-panel" compatible, the backlight needs special handling to work correctly. It is similar to the existing ATNA33XC20 panel, just with a larger resolution and size. Add a new "samsung,atna45af01" compatible to describe this panel in the DT. Use the existing "samsung,atna33xc20" as fallback compatible since existing drivers should work as-is, given that resolution and size are discoverable through the eDP link.
