drm/amdgpu: Validate VM ioctl flags.

commit a2b308044dcaca8d3e580959a4f867a1d5c37fac upstream. None have been defined yet, so reject anybody setting any. Mesa sets it to 0 anyway. Signed-off-by: Bas Nieuwenhuizen Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Don't set struct drm_driver.output_poll_changed

2023-06-21T14:01:02+00:00

commit 0e3172bac3f43759719384403fe2d1e4c61f87e0 upstream. Don't set struct drm_driver.output_poll_changed. It's used to restore the fbdev console. But as amdgpu uses generic fbdev emulation, the console is being restored by the DRM client helpers already. See the functions drm_kms_helper_hotplug_event() and drm_kms_helper_connector_hotplug_event() in drm_probe_helper.c. v2: * fix commit description (Christian) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20221103151446.2638-5-tzimmermann@suse.de Cc: "Gagniuc, Alexandru" Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: add missing radeon secondary PCI ID

commit e61f67749b351c19455ce3085af2ae9af80023bc upstream. 0x5b70 is a missing RV370 secondary id. Add it so we don't try and probe it with amdgpu.

drm/amd: Tighten permissions on VBIOS flashing attributes

2023-06-21T14:00:56+00:00

commit 7ab1a4913d0051cf5196ef7987b5fa42c25e13b6 upstream. Non-root users shouldn't be able to try to trigger a VBIOS flash or query the flashing status. This should be reserved for users with the appropriate permissions.

drm/amd: Make sure image is written to trigger VBIOS image update flow

2023-06-21T14:00:56+00:00

commit 3eb1a3a04056ba3df3205e169b8acc9da0c65a94 upstream. The VBIOS image update flow requires userspace to: 1) Write the image to `psp_vbflash` 2) Read `psp_vbflash` 3) Poll `psp_vbflash_status` to check for completion If userspace reads `psp_vbflash` before writing an image, it's possible that it causes problems that can put the dGPU into an invalid state. Explicitly check that an image has been written before letting a read succeed.
