Blob resources without the cross device flag don't have a uuid to share with other virtio devices. When exporting such blobs, set uuid_state to STATE_ERR so that virtgpu_virtio_get_uuid doesn't hang. Signed-off-by:

Syzbot reported general protection fault in udmabuf_create. The problem was in wrong error handling. In commit 16c243e9 ("udmabuf: Add support for mapping hugepages (v4)") shmem_read_mapping_page() call was replaced with find_get_page_flags(), but find_get_page_flags() returns NULL on failure instead PTR_ERR(). Wrong error checking was causing GPF in get_page(), since passed page was equal to NULL. Fix it by changing if (IS_ER(!hpage)) to if (!hpage) Reported-by: syzbot+e9cd3122a37c5d6c51e8@syzkaller.appspotmail.com Fixes: 16c243e9 ("udmabuf: Add support for mapping hugepages (v4)") Signed-off-by:

By making the CRTC's .vblank_enable() function return an error when it is known that the hardware won't deliver a VBLANK, we can drop the ingenic_drm_atomic_helper_commit_tail() function and use the standard drm_atomic_helper_commit_tail() function instead. Signed-off-by:

Hide the DRM midlayer behind CONFIG_DRM_LEGACY, make functions use the prefix drm_legacy_, and move declarations to drm_legacy.h. In struct drm_device, move the fields irq and irq_enabled behind CONFIG_DRM_LEGACY. All callers have been updated. Signed-off-by:

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers don't benefit from using it. DRM IRQ callbacks are now being called directly or inlined. Calls to platform_get_irq() can fail with a negative errno code. Abort initialization in this case. The DRM IRQ midlayer does not handle this case correctly. Signed-off-by:

DRM IRQ callbacks are now being called directly or inlined. Calls to platform_get_irq() can fail with a negative errno code. Abort initialization in this case. The DRM IRQ midlayer does not handle this case correctly. For most drivers, only the DRM IRQ helpers use irq_enabled from struct drm_device. Tilcdc also uses irq_enabled to make its error rollback work correctly. As the field will become legacy, duplicated the state in the driver's local private structure. Signed-off-by:

drm_file.master should be protected by either drm_device.master_mutex or drm_file.master_lookup_lock when being dereferenced. However, drm_master_get is called on unprotected file_priv->master pointers in vmw_surface_define_ioctl and vmw_gb_surface_define_internal. This is fixed by replacing drm_master_get with drm_file_get_master. Signed-off-by:

For framebuffers with non-zero offset fields, shadow-plane helpers provide a pointer to the first byte of the contained data. Use it in vkms. Also provide use the offset-adjusted data address for the writeback job's output buffers. Output framebuffers with non-zero offsets now have their content written to the correct location.

Move all PLL compute and update functions into mgag200_pll.c. No functional changes to the rsp algorithms. Introduce struct mgag200_pll and mgag200_pll_funcs.
