12fb1ad7 - drm/amdkfd: update process interrupt handling for debug events

Fri, 22 Apr 2022 16:26:18 +0000

drm/amdkfd: update process interrupt handling for debug eventsThe debugger must be notified by any debugger subscribed exceptionthat comes from hardware interrupts.If a debugger session exits, any exceptions it subscribed to may stillhave interrupts in the interrupt ring buffer or KGD/KFD pipeline.To prevent a new session from inheriting stale interrupts, when a newqueue is created, open an interrupt drain and allow the IH ring to drainfrom a timestamped checkpoint. Then inject a custom IV so that oncethe custom IV is picked up by the KFD, it's safe to close the drainand proceed with queue creation.The drain must also be on debug disable as SW interrupts may stillbe processed. Drain at this time and clear all the exception status.The debugger may also not be attached nor subscibed to certainexceptions so forward them directly to the runtime.GFX10 also requires its own IV processing, hence the creation ofkfd_int_process_v10.c. This is because the IV from SQ interrupts arepacked into a new continguous format unlike GFX9. To make this clear,a separate interrupting handling code file was created.Signed-off-by: Jonathan Kim Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher List of files: /linux-6.15/drivers/gpu/drm/amd/amdkfd/Makefile

0ab2d753 - drm/amdkfd: prepare per-process debug enable and disable

Fri, 25 Mar 2022 18:55:30 +0000

drm/amdkfd: prepare per-process debug enable and disableThe ROCm debugger will attach to a process to debug by PTRACE and willexpect the KFD to prepare a process for the target PID, whether thetarget PID has opened the KFD device or not.This patch is to explicity handle this requirement. Further HW modesetting and runtime coordination requirements will be handled infollowing patches.In the case where the target process has not opened the KFD device,a new KFD process must be created for the target PID.The debugger as well as the target process for this case will have notacquired any VMs so handle process restoration to correctly account forthis.To coordinate with HSA runtime, the debugger must be aware of the targetprocess' runtime enablement status and will copy the runtime statusinformation into the debugged KFD process for later query.On enablement, the debugger will subscribe to a set of exceptions whereeach exception events will notify the debugger through a pollable FIFOfile descriptor that the debugger provides to the KFD to manage.Finally on process termination of either the debugger or the target,debugging must be disabled if it has not been done so.Signed-off-by: Jonathan Kim Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher List of files: /linux-6.15/drivers/gpu/drm/amd/amdkfd/Makefile
