drm/amdkfd: Implement kfd2kgd_calls for Arcturus

2019-07-18T19:18:04Z

Arcturus shares most of the kfd2kgd_calls with gfx9. But due to SDMA register address change, it can't share SDMA related functions. Export gfx9 kfd2kgd_calls and implement SDMA related functions for Arcturus. Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: remove duplicated PCIE atomics request

2019-07-01T19:54:47Z

Since amdgpu has always requested PCIE atomics, kfd don't need duplicated PCIE atomics enablement. Referring to amdgpu request result is enough. Signed-off-by: Jack Xiao Reviewed-by: Hawking Zhang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Add function to add/remove gws to kfd process

2019-05-28T19:44:18Z

GWS bo is shared between all kfd processes. Add function to add gws to kfd process's bo list so gws can be evicted from and restored for process. Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Add interface to alloc gws from amdgpu

drm/amdkfd: Add gws number to kfd topology node properties

2019-05-28T19:43:58Z

Add amdgpu_amdkfd interface to get num_gws and add num_gws to /sys/class/kfd/kfd/topology/nodes/x/properties. Only report num_gws if MEC FW support GWS barriers. Currently it is determined by a module parameter which will be replaced with MEC FW version check when firmware is ready.

drm/amdgpu: replace get_user_pages with HMM mirror helpers

2019-05-24T17:21:02Z

Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct. HMM does not pin the page (increase page ref count), so remove related operations like release_pages(), put_page(), mark_page_dirty().

Introduce a new memory type (KFD_IOC_ALLOC_MEM_FLAGS_MMIO_REMAP) and expose mmio page of HDP registers to user space through this new memory type. v2: moved remapped hdp regs to adev struct v3: rename the new memory type to ALLOC_MEM_FLAGS_MMIO_REMAP v4: use more generic function name v5: Fail remapped mmio allocation for asics before gfx9 Signed-off-by: Oak Zeng Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: get_fw_version isn't ASIC specific

2019-04-19T16:32:40Z

Method of getting firmware version is the same across ASICs, so remove them from ASIC-specific files and create one in amdgpu_amdkfd.c. This new created get_fw_version simply reads fw_version from adev->gfx than parsing the ucode header. Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher
