drm/amdgpu/swsmu: fix ARC build errors

2020-10-07T21:04:27Z

We want to use the dev_* functions here rather than the pr_* variants. Switch to using dev_warn() which mirrors what we do on other asics. Fixes the following build errors on ARC: ../drivers/gpu/drm/amd/amdgpu/../powerplay/navi10_ppt.c: In function 'navi10_fill_i2c_req': ../arch/arc/include/asm/bug.h:24:2: error: implicit declaration of function 'pr_warn'; did you mean 'drm_warn'?

drm/amdgpu: fix NULL pointer dereference for Renoir

2020-10-07T21:03:08Z

Commit c1cf79ca5ced46 ("drm/amdgpu: use IP discovery table for renoir") introduced a NULL pointer dereference when booting with amdgpu.discovery=0, because it removed the call of vega10_reg_base_init() for that case. Fix this by calling that funcion if amdgpu_discovery == 0 in addition to the case that amdgpu_discovery_reg_base_init() failed.

drm/nouveau/device: return error for unknown chipsets

2020-10-07T05:33:00Z

Previously the code relied on device->pri to be NULL and to fail probing later. We really should just return an error inside nvkm_device_ctor for unsupported GPUs.

drm/amd/pm: setup APU dpm clock table in SMU HW initialization

2020-09-30T13:29:00Z

As the dpm clock table is needed during DC HW initialization. And that (DC HW initialization) comes before smu_late_init() where current APU dpm clock table setup is performed. So, NULL pointer dereference will be triggered. By moving APU dpm clock table setup to smu_hw_init(), this can be avoided.

drm/vmwgfx: Fix error handling in get_node

2020-09-30T03:44:28Z

ttm_mem_type_manager_func.get_node was changed to return -ENOSPC instead of setting the node pointer to NULL. Unfortunately vmwgfx still had two places where it was explicitly converting -ENOSPC to 0 causing regressions. This fixes those spots by allowing -ENOSPC to be returned. That seems to fix recent regressions with vmwgfx. Signed-off-by: Zack Rusin Reviewed-by: Roland Scheidegger Reviewed-by: Martin Krastev Sigend-off-by: Roland Scheidegger

drm/amd/display: remove duplicate call to rn_vbios_smu_get_smu_version()

Commit 78fe9f63947a2b ("drm/amd/display: Remove DISPCLK Limit Floor for Certain SMU Versions") added a call to rn_vbios_smu_get_smu_version() to set clk_mgr->smu_ver.
