drm/amd/amdgpu: Add GPIO resources required for amdisp

2025-05-28T20:01:39Z

ISP is a child device to GFX, and its device specific information is not available in ACPI. Adding the 2 GPIO resources required for ISP_v4_1_1 in amdgpu_isp driver. - GPIO 0 to allow sensor driver to enable and disable sensor module. - GPIO 85 to allow ISP driver to enable and disable ISP RGB streaming mode.

drm/amdgpu: Add debug bit for userptr usage

2025-05-07T21:45:04Z

In VM debug mode, it is desirable to notify the application to correct the freeing sequence by unmapping the memory before destroying the userptr in the old userptr path. Add a bitmask to decide whether to send gpu vm fault to the applition. Signed-off-by: Shane Xiao Reviewed-by: Christian König Signed-off-by: Alex Deucher

Revert "drm/amd: Stop evicting resources on APUs in suspend"

2025-05-07T21:42:30Z

This reverts commit 3a9626c816db901def438dc2513622e281186d39. This breaks S4 because we end up setting the s3/s0ix flags even when we are entering s4 since prepare is used by both flows. The causes both the S3/s0ix and s4 flags to be set which breaks several checks in the driver which assume they are mutually exclusive.

drm/amdgpu: Add Support for enforcing isolation without Cleaner Shader

2025-05-05T17:29:53Z

Adjusted the enforce isolation setting handling to include the ability to disable the cleaner shader without affecting isolation between tasks. v2: Updated enforce isolation documentation and parameters.

drm/amdgpu/userq: add helpers to start/stop scheduling

This will be used to stop/start user queue scheduling for example when switching between kernel and user queues when enforce isolation is enabled. v2: use idx v3: only stop compute/gfx queues Reviewed-by: Sunil Khatri Signed-off-by: Alex Deucher

drm/amdgpu/userq: rework driver parameter

2025-04-21T14:55:47Z

Replace disable_kq parameter with user_queue parameter. The parameter has the following logic: -1 = auto (ASIC specific default) 0 = user queues disabled 1 = user queues enabled and kernel queues enabled (if supported) 2 = user queues enabled and kernel queues disabled The default behavior (-1) is currently the same as 0 for current ASICs. To enable user queues (in addition to kernel queues) set user_queue=1. To enable user queues and disable kernel queues (to make all resources available to user queues), set user_queue=2.

drm/amdgpu: adjust enforce_isolation handling

2025-04-11T20:58:15Z

Switch from a bool to an enum and allow more options for enforce isolation. There are now 3 modes of operation: - Disabled (0) - Enabled (serialization and cleaner shader) (1) - Enabled in legacy mode (no serialization or cleaner shader) (2) This provides better flexibility for more use cases.
