[PATCH] drm/amdgpu: avoid using null object of framebuffer

Instead of using state->fb->obj[0] directly, get object from framebuffer by calling drm_gem_fb_get_obj() and return error code when object is null to avoid using null object of framebuffer. Signed-off-by: Julia Zhang --- drivers/gpu/drm/amd/amdgpu/amdgpu_vkms.c | 17 +++--

[PATCH v2 0/1] Implementation of resource_query_layout

Hi all, Sorry to late reply. This is v2 of the implementation of resource_query_layout. This adds a new ioctl to let guest query information of host resource, which is originally from Daniel Stone. We add some changes to support query the correct stride of host resource before it's created, which

[PATCH 1/2] drm/virtio: Implement RESOURCE_GET_LAYOUT ioctl

From: Daniel Stone This ioctl allows the guest to discover how the guest actually allocated the underlying buffer, which allows buffers to be used for GL<->Vulkan interop and through standard window systems. It's also a step towards properly supporting modifiers in the guest. ---
