[git pull] amdkfd next 4.19

Hi Dave, This is amdkfd pull for 4.19. The major changes are: - Add Raven support. Raven refers to Ryzen APUs with integrated GFXv9 GPU. - Integrate GPU reset support In addition, there are a couple of small fixes and improvements, such as: - Better handling and reporting to user of VM faults - Fix race upon context restore - Allow the user to use specific Compute Units - Basic power management Thanks, Oded The following changes since commit 6d52aacd92c60331ec8c3117522f4301b5195e28: Merge branch 'drm-next-4.19' of git://people.freedesktop.org/~agd5f/linux into drm-next (2018-07-27 12:31:48 +1000) are available in the git repository at: git://people.freedesktop.org/~gabbayo/linux tags/drm-amdkfd-next-2018-07-28 for you to fetch changes up to b5aa3f4aef724e9c0f626dcf69948b22efcc5176: drm/amdkfd: Call kfd2kgd.set_compute_idle (2018-07-16 19:10:37 -0400) ---------------------------------------------------------------- Arnd Bergmann (1): drm/admkfd use modern ktime accessors Felix Kuehling (6): drm/amdkfd: Reliably prevent reclaim-FS while holding DQM lock drm/amdkfd: Stop using GFP_NOIO explicitly drm/amd: Add CU-masking ioctl definition to kfd_ioctl.h drm/amdkfd: Add CU-masking ioctl to KFD drm/amdgpu: Add kfd2kgd.set_compute_idle interface drm/amdkfd: Call kfd2kgd.set_compute_idle Jay Cornwall (1): drm/amdkfd: Fix race between scheduler and context restore Lan Xiao (1): drm/amdkfd: fix zero reading of VMID and PASID for Hawaii Moses Reuben (1): drm/amdkfd: send SIGSEGV to process upon KFD_EVENT_TYPE_MEMORY Shaoyun Liu (13): drm/amd: Add gpu reset interfaces between amdgpu and amdkfd drm/amd: Add kfd ioctl defines for hw_exception event drm/amdkfd: Add gpu reset interface and place holder drm/amdgpu: Call KFD reset handlers during GPU reset drm/amdkfd: Implement GPU reset handlers in KFD drm/amdgpu: Enable the gpu reset from KFD drm/amdkfd: Implement hang detection in KFD and call amdgpu drm/amdgpu: Don't use shadow BO for compute context drm/amdgpu: Check NULL pointer for job before reset job's ring drm/amdkfd: Fix kernel queue 64 bit doorbell offset calculation drm/amdgpu: Avoid invalidate tlbs when gpu is on reset drm/amdgpu: Avoid destroy hqd when GPU is on reset drm/amdkfd: Add debugfs interface to trigger HWS hang Wei Lu (1): drm/amdkfd: Fix error codes in kfd_get_process Yong Zhao (10): drm/amdkfd: Introduce KFD module parameter halt_if_hws_hang drm/amdkfd: Use module parameters noretry as the internal variable name drm/amdkfd: Replace mqd with mqd_mgr as the variable name for mqd_manager drm/amdkfd: Clean up reference of radeon drm/amdkfd: Consolidate duplicate memory banks info in topology drm/amdkfd: Make SDMA engine number an ASIC-dependent variable drm/amdkfd: Avoid flooding dmesg on Raven due to IOMMU issues drm/amdkfd: Workaround to accommodate Raven too many PPR issue drm/amdkfd: Optimize out some duplicated code in kfd_signal_iommu_event() drm/amdkfd: Enable Raven for KFD shaoyunl (2): drm/amdgpu: save vm fault information for amdkfd drm/amdkfd: Handle VM faults in KFD drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c | 35 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h | 10 + drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gfx_v7.c | 27 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gfx_v8.c | 9 + drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gfx_v9.c | 8 + drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 14 + drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 7 +- drivers/gpu/drm/amd/amdgpu/amdgpu_gmc.h | 2 + drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c | 13 +- drivers/gpu/drm/amd/amdgpu/gmc_v7_0.c | 33 +- drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c | 33 +- drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c | 54 ++- drivers/gpu/drm/amd/amdkfd/cik_int.h | 7 +- drivers/gpu/drm/amd/amdkfd/cwsr_trap_handler.h | 458 +++++++++++---------- .../gpu/drm/amd/amdkfd/cwsr_trap_handler_gfx8.asm | 18 +- .../gpu/drm/amd/amdkfd/cwsr_trap_handler_gfx9.asm | 16 +- drivers/gpu/drm/amd/amdkfd/kfd_chardev.c | 69 +++- drivers/gpu/drm/amd/amdkfd/kfd_crat.c | 57 ++- drivers/gpu/drm/amd/amdkfd/kfd_dbgdev.c | 1 -
