2020-09-15drm/virtio: add virtio_gpu_cmd_unref_resource error handlingGerd Hoffmann1-1/+4
Usually we wait for the host to complete the unref request, then cleanup the guest-side state of the object in the completion callback. When submitting the unref command failed the completion callback will not be called though, so cleanup right away. Fixes a WARN on stale mm entries on driver shutdown.

2020-09-10drm: virtio: fix common struct sg_table related issuesMarek Szyprowski2-22/+26
The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function returns the number of the created entries in the DMA address space. However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and dma_unmap_sg must be called with the original number of the entries passed to the dma_map_sg(). struct sg_table is a common structure used for describing a non-contiguous memory buffer, used commonly in the DRM and graphics subsystems. It consists of a scatterlist with memory pages and DMA addresses (sgl entry), as well as the number of scatterlist entries: CPU pages (orig_nents entry) and DMA mapped pages (nents entry). It turned out that it was a common mistake to misuse nents and orig_nents entries, calling DMA-mapping functions with a wrong number of entries or ignoring the number of mapped entries returned by the dma_map_sg() function. To avoid such issues, lets use a common dma-mapping wrappers operating directly on the struct sg_table objects and use scatterlist page iterators where possible. This, almost always, hides references to the nents and orig_nents entries, making the code robust, easier to follow and copy/paste safe.

2020-06-03drm/virtio: Call the right shmem helpersDaniel Vetter1-1/+1
drm_gem_shmem_get_sg_table is meant to implement obj->funcs->get_sg_table, for prime exporting. The one we want is drm_gem_shmem_get_pages_sgt, which also handles imported dma-buf, not just native objects. v2: Rebase, this stuff moved around in commit 2f2aa13724d56829d910b2fa8e80c502d388f106 Author: Gerd Hoffmann <[email protected]> Date: Fri Feb 7 08:46:38 2020 +0100 drm/virtio: move virtio_gpu_mem_entry initialization to new function Acked-by: Thomas Zimmermann <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> Cc: David Airlie <[email protected]> Cc: Gerd Hoffmann <[email protected]> Cc: [email protected] Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-05-19drm/virtio: remove _unlocked suffix in drm_gem_object_put_unlockedEmil Velikov3-7/+7
Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner. Done via the following script: __from=drm_gem_object_put_unlocked __to=drm_gem_object_put for __file in $(git grep --name-only $__from); do sed -i "s/$__from/$__to/g" $__file; done Cc: David Airlie <[email protected]> Cc: Gerd Hoffmann <[email protected]> Cc: Daniel Vetter <[email protected]> Signed-off-by: Emil Velikov <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Acked-by: Gerd Hoffmann <[email protected]> Acked-by: Thomas Zimmermann <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

If 3D is enabled, but userspace requests a dumb buffer, we will call CTX_ATTACH_RESOURCE before actually creating the context.

2020-04-06drm/virtio: fix OOB in virtio_gpu_object_createJiri Slaby1-6/+8
After commit f651c8b05542 ("drm/virtio: factor out the sg_table from virtio_gpu_object"), virtio_gpu_create_object allocates too small space to fit everything in. It is because it allocates struct virtio_gpu_object, but should allocate a newly added struct virtio_gpu_object_shmem which has 2 more members. So fix that by using correct type in virtio_gpu_create_object.
