drm/amdgpu: support indirect access reg outside of mmio bar (v2)

2020-10-01T14:42:55Z

support both direct and indirect accessor in unified helper functions. v2: Retire indirect mmio access via mm_index/data Signed-off-by: Hawking Zhang Reviewed-by: Christian König Reviewed-by: Alex Deucher Reviewed-by: Kevin Wang Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher

drm/amdgpu: add helper function for indirect reg access (v3)

2020-10-01T14:42:13Z

Add helper function in order to remove RREG32/WREG32 in current pcie_rreg/wreg function for soc15 and onwards adapters. PCIE_INDEX/DATA pairs are used to access regsiters outside of mmio bar in the helper functions. The new helper functions help remove the recursion of amdgpu_mm_rreg/wreg from pcie_rreg/wreg and provide the oppotunity to centralize direct and indirect access in a single function. v2: Fixed typo and refine the comments v3: Remove unnecessary volatile local variable Signed-off-by: Hawking Zhang Reviewed-by: Alex Deucher Reviewed-by: Kevin Wang Reviewed-by: Christian König Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher

drm/amdgpu: use function pointer for gfxhub functions

2020-09-30T17:50:13Z

gfxhub functions are now called from function pointers, instead of from asic-specific functions. Signed-off-by: Oak Zeng Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Fix consecutive DPC recovery failures.

2020-09-15T21:25:04Z

Cache the PCI state on boot and before each case where we might loose it. v2: Add pci_restore_state while caching the PCI state to avoid breaking PCI core logic for stuff like suspend/resume. v3: Extract pci_restore_state from amdgpu_device_cache_pci_state to avoid superflous restores during GPU resets and suspend/resumes. v4: Style fixes.

drm/amdgpu: Avoid accessing HW when suspending SW state

2020-09-15T21:24:39Z

At this point the ASIC is already post reset by the HW/PSP so the HW not in proper state to be configured for suspension, some blocks might be even gated and so best is to avoid touching it. v2: Rename in_dpc to more meaningful name Signed-off-by: Andrey Grodzovsky Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Implement DPC recovery

drm/amdkfd: fix set kfd node ras properties value

2020-08-26T20:40:19Z

The ctx->features are new RAS implementation which is only available for Vega20 and onwards, it is not available for vega10, vega10 should follow legacy ECC implementation. Changed from V1: wrap function to initialize kfd node properties Changed from V2: remove wrap function and SDMA SRAM ECC check Signed-off-by: Stanley.Yang Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher

drm/amdgpu: add an asic callback for pre asic init

This callback can be used by asics that need to do something special prior to calling atom asic init. Acked-by: Nirmoy Das Signed-off-by: Alex Deucher

drm/amdgpu: Embed drm_device into amdgpu_device (v3)

2020-08-26T20:40:17Z

a) Embed struct drm_device into struct amdgpu_device. b) Modify the inline-f drm_to_adev() accordingly. c) Modify the inline-f adev_to_drm() accordingly. d) Eliminate the use of drm_device.dev_private, in amdgpu. e) Switch from using drm_dev_alloc() to drm_dev_init(). f) Add a DRM driver release function, which frees the container amdgpu_device after all krefs on the contained drm_device have been released. v2: Split out adding adev_to_drm() into its own patch (previous commit), making this patch more succinct and clear. More detailed commit description. v3: squash in fix to call drmm_add_final_kfree() to avoid a warning. Signed-off-by: Luben Tuikov Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
