Add DMABuf support to virtio wayland driver. |
||||
Issue descriptionAdd a new allocation type that returns a virtual FD that maps to host side DMABuf backed memory. The FD should work with the linux_dmabuf protocol that can be used over virtio wayland connections.

This implements DMABuf allocation type in the virtio wayland device. We attempt to locate a supported DRM device prior to engaging the device jail. If found, the DRM device is passed to the wayland device code and used to serve DMABuf allocations. DMABuf support can be disabled by not providing crosvm with access to any DRM device nodes. The guest is expected to handle the case when DMABuf allocation fails and fall-back to standard shared memory. This initial change uses DRM directly but is structured in a way that would allow the allocator to be replaced by minigbm with minimal effort.

Suppot for this format is possible as we copy into dmabufs when using the 'virtwl-dmabuf' driver. The mmap utilities have been updated to support multi-plane formats. The code is still limited to 2 planes and the same bpp for all planes as that's all we need for NV12. It can be made even more flexible if needed in the future. NV12 is useful for efficient video playback. It allows a software decode pipeline to output NV12 and a single copy before planes can be scanned out using an HW overlay.

The following revision refers to this bug: https://chromium.googlesource.com/chromiumos/platform/crosvm/+/22272dd4b26cf1e3797ea8f7ea0331d71cbd399a commit 22272dd4b26cf1e3797ea8f7ea0331d71cbd399a Author: David Reveman <reveman@chromium.org> Date: Tue Jun 19 21:38:53 2018 virtwl: implement dmabuf sync support This provides proper synchronization for guest access to DMABufs. Virtio wayland device is given access to the DMA_BUF_SYNC ioctl in order to implement this. Being able to use this directly in the virtio wayland device process is important as these calls can sometimes be relatively expensive and they are frequent enough that avoiding another context switch is useful for good performance.

This removes rendering artifacts from writes to the buffer not having been flushed before presentation.
