drm/amdkfd: Don't assign dGPUs to APU topology devices

2019-02-27T09:08:55+00:00

[ Upstream commit bbdf514fe5648566b0754476cbcb92ac3422dde2 ] dGPUs need their own topology devices. Don't assign them to APU topology devices with CPU cores.

drm/amdkfd: fix interrupt spin lock

drm/amdkfd: Fix incorrect use of process->mm

2018-10-04T15:37:25+00:00

This mm_struct pointer should never be dereferenced. If running in a user thread, just use current->mm. If running in a kernel worker use get_task_mm to get a safe reference to the mm_struct.

drm/amdkfd: Fix ATS capablity was not reported correctly on some APUs

2018-09-20T15:25:23+00:00

Because CRAT_CU_FLAGS_IOMMU_PRESENT was not set in some BIOS crat, we need to workaround this. For future compatibility, we also overwrite the bit in capability according to the value of needs_iommu_device.

drm/amdkfd: Change the control stack MTYPE from UC to NC on GFX9

2018-09-20T15:25:17+00:00

CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.

drm/amdkfd: Call kfd2kgd.set_compute_idle

2018-07-16T23:10:37+00:00

User mode queue submissions don't go through KFD. Therefore we don't know exactly when compute is idle or not idle. We use the existence of user mode queues on a device as an approximation. register_process is called when the first queue of a process is created. Conversely unregister_process is called when the last queue is destroyed. The first process that is registered takes compute out of idle. The last process that is unregisters sets compute back to idle. Signed-off-by: Felix Kuehling Reviewed-by: Eric Huang Reviewed-by: Alex Deucher Signed-off-by: Oded Gabbay

drm/amdkfd: Add CU-masking ioctl to KFD

2018-07-14T23:05:59+00:00

CU-masking allows a KFD client to control the set of CUs used by a user mode queue for executing compute dispatches. This can be used for optimizing the partitioning of the GPU and minimize conflicts between concurrent tasks.
