drm/amdgpu: Check if fd really is an amdgpu fd.

2022-04-15T12:15:07+00:00

commit 021830d24ba55a578f602979274965344c8e6284 upstream. Otherwise we interpret the file private data as drm & amdgpu data while it might not be, possibly allowing one to get memory corruption.

drm/amd/display: fix ref count leak in amdgpu_drm_ioctl

2020-09-03T09:24:19+00:00

[ Upstream commit 5509ac65f2fe5aa3c0003237ec629ca55024307c ] in amdgpu_drm_ioctl the call to pm_runtime_get_sync increments the counter even in case of failure, leading to incorrect ref count. In case of failure, decrement the ref count before returning. Signed-off-by: Navid Emamdoost Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amdgpu: Bail earlier when amdgpu.cik_/si_support is not set to 1

2019-10-29T08:19:55+00:00

commit 984d7a929ad68b7be9990fc9c5cfa5d5c9fc7942 upstream. Bail from the pci_driver probe function instead of from the drm_driver load function. This avoid /dev/dri/card0 temporarily getting registered and then unregistered again, sending unwanted add / remove udev events to userspace. Specifically this avoids triggering the (userspace) bug fixed by this plymouth merge-request: https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59 Note that despite that being a userspace bug, not sending unnecessary udev events is a good idea in general.

drm/amdgpu: Allow to create BO lists in CS ioctl v3

2018-07-16T20:29:47+00:00

This change is to support MESA performace optimization. Modify CS IOCTL to allow its input as command buffer and an array of buffer handles to create a temporay bo list and then destroy it when IOCTL completes. This saves on calling for BO_LIST create and destry IOCTLs in MESA and by this improves performance. v2: Avoid inserting the temp list into idr struct. v3: Remove idr alloation from amdgpu_bo_list_create. Remove useless argument from amdgpu_cs_parser_fini Minor cosmetic stuff. v4: Revert amdgpu_bo_list_destroy back to static Signed-off-by: Andrey Grodzovsky Reviewed-by: Christian König Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher

drm/amd: Replace drm_dev_unref with drm_dev_put

2018-07-05T21:39:53+00:00

This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces. Signed-off-by: Thomas Zimmermann Signed-off-by: Alex Deucher
