2025-03-13drm/amdgpu: Reduce dequeue retry timeout for gfx9 familyHarish Kasiviswanathan
Dequeue retry timeout controls the interval between checks for unmet conditions. On MI series, reduce this from 0x40 to 0x1 (~ 1 uS). The cost of additional bandwidth consumed by CP when polling memory shouldn't be substantial.

2025-03-05drm/amdkfd: implement per queue sdma reset for gfx 9.4+Jonathan Kim
To reset hung SDMA queues on GFX 9.4+ for the GFX9 family, a soft reset must be issued through SMU. Since soft resets will reset an entire SDMA engine, use a common KGD call to do the reset as the KGD will handle avoiding a reset of in flight GFX and paging queues on that engine. In addition, create a common call for all reset types to simplify the handling of module parameter settings that block gpu resets.

Support per-queue reset for GFX9. The recommendation is for the driver to target reset the HW queue via a SPI MMIO register write. Since this requires pipe and HW queue info and MEC FW is limited to doorbell reports of hung queues after an unmap failure, scan the HW queue slots defined by SET_RESOURCES first to identify the user queue candidates to reset. Only signal reset events to processes that have had a queue reset. If queue reset fails, fall back to GPU reset.

2023-11-17amdgpu: Adjust kmalloc_array calls for new -Walloc-sizeSam James
GCC 14 introduces a new -Walloc-size included in -Wextra which errors out on various files in drivers/gpu/drm/amd/amdgpu like: ``` amdgpu_amdkfd_gfx_v8.c:241:15: error: allocation of insufficient size ‘4’ for type ‘uint32_t[2]’ {aka ‘unsigned int[2]'} with size ‘8’ [-Werror=alloc-size] ``` This is because each HQD_N_REGS is actually a uint32_t[2]. Move the * 2 to the size argument so GCC sees we're allocating enough. Originally did 'sizeof(uint32_t) * 2' for the size but a friend suggested 'sizeof(**dump)' better communicates the intent.

2023-06-09drm/amdkfd: add debug wave launch override operationJonathan Kim
This operation allows the debugger to override the enabled HW exceptions on the device. On debug devices that only support the debugging of a single process, the HW exceptions are global and set through the SPI_GDBG_TRAP_MASK register. Because they are global, only address watch exceptions are allowed to be enabled. In other words, the debugger must preserve all non-address watch exception states in normal mode operation by barring a full replacement override or a non-address watch override request. For multi-process debugging, all HW exception overrides are per-VMID so all exceptions can be overridden or fully replaced. In order for the debugger to know what is permissible, returned the supported override mask back to the debugger along with the previously enable overrides.

2023-06-09drm/amdgpu: add configurable grace period for unmap queuesJonathan Kim
The HWS schedule allows a grace period for wave completion prior to preemption for better performance by avoiding CWSR on waves that can potentially complete quickly. The debugger, on the other hand, will want to inspect wave status immediately after it actively triggers preemption (a suspend function to be provided). To minimize latency between preemption and debugger wave inspection, allow immediate preemption by setting the grace period to 0. Note that setting the preepmtion grace period to 0 will result in an infinite grace period being set due to a CP FW bug so set it to 1 for now.

Implement the per-device calls to enable or disable HW debug mode for GFX9 prior to GFX9.4.1. GFX9.4.1 and onward will require their own enable/disable sequence as follow on patches. When hardware debug mode setting is requested, waves will inherit these settings in the Shader Processor Input's (SPI) Sequencer Global Block (SQG). This means that the KGD must drain all waves from the SPI into SQG (approximately 96 SPI clock cycles) prior to debug mode setting to ensure that the order of operations that the debugger expects with regards to debug mode setting transaction requests and wave inheritence of that mode is upheld. Also ensure that exception overrides are reset to their original state prior to debug enable or disable.

Pull drm updates from Dave Airlie: "Not a major amount of change, the i915 trees got split into display and gt trees to better facilitate higher level review, and there's a major refactoring of i915 GEM locking to use more core kernel concepts (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards get DC support, nouveau got a bump in displayport support with common code extraction from i915. Outside of drm this contains a couple of patches for hexint moduleparams which you've acked, and a virtio common code tree that you should also get via it's regular path.

2020-09-17drm, iommu: Change type of pasid to u32Fenghua Yu
PASID is defined as a few different types in iommu including "int", "u32", and "unsigned int". To be consistent and to match with uapi definitions, define PASID and its variations (e.g. max PASID) as "u32". "u32" is also shorter and a little more explicit than "unsigned int". No PASID type change in uapi although it defines PASID as __u64 in some places.
