drm/amdkfd: fix gfx11 restrictions on debugging cooperative launch

2026-01-21T02:50:12Z

Restrictions on debugging cooperative launch for GFX11 devices should align to CWSR work around requirements. i.e. devices without the need for the work around should not be subject to such restrictions.

drm/amdkfd: fix and enable ttmp setup for gfx11

2023-07-27T18:59:29Z

The MES cached process context must be cleared on adding any queue for the first time. For proper debug support, the MES will clear it's cached process context on the first call to SET_SHADER_DEBUGGER. This allows TTMPs to be pesistently enabled in a safe manner.

drm/amdkfd: add multi-process debugging support for GC v9.4.3

2023-07-12T15:12:09Z

Similar to GC v9.4.2, GC v9.4.3 should use the 5-Dword extended MAP_PROCESS packet to support multi-process debugging. Update the mutli-process debug support list so that the KFD updates the runlist on debug mode setting and that it allocates enough GTT memory during KFD device initialization.

drm/amdkfd: add debug device snapshot operation

2023-06-09T16:37:00Z

Similar to queue snapshot, return an array of device information using an entry_size check and return. Unlike queue snapshots, the debugger needs to pass to correct number of devices that exist. If it fails to do so, the KFD will return the number of actual devices so that the debugger can make a subsequent successful call.

drm/amdkfd: add debug query exception info operation

2023-06-09T16:36:53Z

Allow the debugger to query additional info based on an exception code. For device exceptions, it's currently only memory violation information. For process exceptions, it's currently only runtime information. Queue exception only report the queue exception status. The debugger has the option of clearing the target exception on query.
