2024-09-06drm/amdgpu: enable gfxoff quirk on HP 705G4Peng Liu
Enabling gfxoff quirk results in perfectly usable graphical user interface on HP 705G4 DM with R5 2400G. Without the quirk, X server is completely unusable as every few seconds there is gpu reset due to ring gfx timeout.

2024-08-20drm/amdgpu/gfx9: Apply Isolation Enforcement to GFX & Compute ringsSrinivasan Shanmugam
This commit applies isolation enforcement to the GFX and Compute rings in the gfx_v9_0 module. The commit sets `amdgpu_gfx_enforce_isolation_ring_begin_use` and `amdgpu_gfx_enforce_isolation_ring_end_use` as the functions to be called when a ring begins and ends its use, respectively. `amdgpu_gfx_enforce_isolation_ring_begin_use` is called when a ring begins its use. This function cancels any scheduled `enforce_isolation_work` and, if necessary, signals the Kernel Fusion Driver (KFD) to stop the runqueue. `amdgpu_gfx_enforce_isolation_ring_end_use` is called when a ring ends its use. This function schedules `enforce_isolation_work` to be run after a delay. These functions are part of the Enforce Isolation Handler, which enforces shader isolation on AMD GPUs to prevent data leakage between different processes.

2024-08-20drm/amdgpu/gfx9: Implement cleaner shader support for GFX9 hardwareSrinivasan Shanmugam
The patch modifies the gfx_v9_0_kiq_set_resources function to write the cleaner shader's memory controller address to the ring buffer. It also adds a new function, gfx_v9_0_ring_emit_cleaner_shader, which emits the PACKET3_RUN_CLEANER_SHADER packet to the ring buffer. This patch adds support for the PACKET3_RUN_CLEANER_SHADER packet in the gfx_v9_0 module. This packet is used to emit the cleaner shader, which is used to clear GPU memory before it's reused, helping to prevent data leakage between different processes. Finally, the patch updates the ring function structures to include the new gfx_v9_0_ring_emit_cleaner_shader function. This allows the cleaner shader to be emitted as part of the ring's operations.

Moving back to a single queue in this case also helps when high priority app are used: in this case the gpu_scheduler priority handling will work as expected - much better than ring_muxer with its 2 independant schedulers competing for the same hardware queue.

After that the preempted ib is resubmitted, CP would clear some locals stored for ib resume when reading the completed status, which causes gpu hang in some cases. Always set status as preempted for those resubmitted ib instead of reading everything from the CSA buffer.

rlc_init() is part of sw_init() so it should not touch hardware. Additionally, calling the rlc update_spm_vmid() callback directly invokes a gfx on/off cycle which could result in powergating being enabled before hw init is complete. Split update_spm_vmid() into an internal implementation for local use without gfxoff interaction and then the rlc callback which includes gfxoff handling. lbpw_init also touches hardware so mvoe that to rlc_resume as well.

2023-06-09drm/amdgpu: add gfx9.4.1 hw debug mode enable and disable callsJonathan Kim
On GFX9.4.1, the implicit wait count instruction on s_barrier is disabled by default in the driver during normal operation for performance requirements. There is a hardware bug in GFX9.4.1 where if the implicit wait count instruction after an s_barrier instruction is disabled, any wave that hits an exception may step over the s_barrier when returning from the trap handler with the barrier logic having no ability to be aware of this, thereby causing other waves to wait at the barrier indefinitely resulting in a shader hang. This bug has been corrected for GFX9.4.2 and onward. Since the debugger subscribes to hardware exceptions, in order to avoid this bug, the debugger must enable implicit wait count on s_barrier for a debug session and disable it on detach. In order to change this setting in the in the device global SQ_CONFIG register, the GFX pipeline must be idle. GFX9.4.1 as a compute device will either dispatch work through the compute ring buffers used for image post processing or through the hardware scheduler by the KFD. Have the KGD suspend and drain the compute ring buffer, then suspend the hardware scheduler and block any future KFD process job requests before changing the implicit wait count setting. Once set, resume all work. Signed-off-by: Jonathan Kim <jonathan.kim@amd.com> Reviewed-by: Felix Kuehling <felix.kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-06-09drm/amdgpu: setup hw debug registers on driver initializationJonathan Kim
Add missing debug trap registers references and initialize all debug registers on boot by clearing the hardware exception overrides and the wave allocation ID index. The debugger requires that TTMPs 6 & 7 save the dispatch ID to map waves onto dispatch during compute context inspection. In order to correctly set this up, set the special reserved CP bit by default whenever the MQD is initailized.

2023-06-09drm/amdgpu: Reset CP_VMID_PREEMPT after trailing fence signaledJiadong Zhu
When MEC executes unmap_queue for mid command buffer preemption, it will kick the write pointer of the gfx ring, set CP_VMID_PREEMPT to trigger the preemption and wait for CP_VMID_PREEMPT becomes zero after the preemption done. There is a race condition that PFP may excute the resetting command before MEC set CP_VMID_PREEMPT. As a result, hang happens as CP_VMID_PREEMPT is always 0xffff. To avoid this, we send resetting CP_VMID_PREEMPT command after the trailing fence is siganled and update gfx write pointer explicitly.
