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

2018-10-18T07:18:17+00:00

[ Upstream commit 44d8cc6f1a905e4bb1d4221a898abb0d7e9d100a ] 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

2018-10-18T07:18:17+00:00

[ Upstream commit 15426dbb65c5b37680d27e84d58a1ed3b8532518 ] 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: Fix error codes in kfd_get_process

[ Upstream commit e47cb828eb3fca3e8999a0b9aa053dda18552071 ] Return ERR_PTR(-EINVAL) if kfd_get_process fails to find the process. This fixes kernel oopses when a child process calls KFD ioctls with a file descriptor inherited from the parent process.

drm/amdkfd: fix clock counter retrieval for node without GPU

2018-04-24T09:34:44+00:00

Currently if a user requests clock counters for a node without a GPU resource we will always return EINVAL. Instead if no GPU resource is attached, fill the gpu_clock_counter argument with zeroes so that we may proceed and return valid CPU counters.
