drm/amd/amdgpu: Increase HWIP_MAX_INSTANCE to 10

2021-09-22T10:27:55+00:00

commit 67a44e659888569a133a8f858c8230e9d7aad1d5 upstream. Seems like newer cards can have even more instances now. Found by UBSAN: array-index-out-of-bounds in drivers/gpu/drm/amd/amdgpu/amdgpu_discovery.c:318:29 index 8 is out of range for type 'uint32_t *[8]' Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1697 Cc: stable@vger.kernel.org Signed-off-by: Ernst Sjöstrand Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amd/display: Add a backlight module option

2021-03-17T16:06:18+00:00

commit 7a46f05e5e163c00e41892e671294286e53fe15c upstream. There seem devices that don't work with the aux channel backlight control. For allowing such users to test with the other backlight control method, provide a new module option, aux_backlight, to specify enabling or disabling the aux backport support explicitly. As default, the aux support is detected by the hardware capability. v2: make the backlight option generic in case we add future backlight types (Alex) BugLink: https://bugzilla.opensuse.org/show_bug.cgi?id=1180749 BugLink: https://gitlab.freedesktop.org/drm/amd/-/issues/1438 Reviewed-by: Nicholas Kazlauskas Signed-off-by: Takashi Iwai Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

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

2020-10-01T14:42:55+00:00

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)

2020-10-01T14:42:13+00:00

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

2020-09-30T17:50:13+00:00

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.

2020-09-15T21:25:04+00:00

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

2020-09-15T21:24:39+00:00

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

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.
