2018-11-14drm/virtio: add in/out fence support for explicit synchronizationRobert Foss
When the execbuf call receives an in-fence it will get the dma_fence related to that fence fd and wait on it before submitting the draw call. On the out-fence side we get fence returned by the submitted draw call and attach it to a sync_file and send the sync_file fd to userspace. On error -1 is returned to userspace.

2018-11-14drm/virtio: add uapi for in and out explicit fencesRobert Foss
Add a new field called fence_fd that will be used by userspace to send in-fences to the kernel and receive out-fences created by the kernel. This uapi enables virtio to take advantage of explicit synchronization of dma-bufs. There are two new flags: * VIRTGPU_EXECBUF_FENCE_FD_IN to be used when passing an in-fence fd. * VIRTGPU_EXECBUF_FENCE_FD_OUT to be used when requesting an out-fence fd The execbuffer IOCTL is now read-write to allow the userspace to read the out-fence.

A while back we removed it, yet that lead to regressions. At some later point, I've attempted to remove it again without fully grasping the unique (pun intended) situation that virtio is in. Add a bulky comment to document why the call should stay as-is, for the next person who's around. As a Tl;Dr: virtio sits on top of struct virtio_device, which confuses dev_is_pci(), wrong info gets sent to userspace and X doesn't start.

2018-09-26virtio: Support prime objects vmap/vunmapEzequiel Garcia
Implement vmap/vunmap so we can export dmabufs to other drivers, such as video4linux. Tested with a virtio-gpu / vivid (virtual capture driver) pipeline, where the vivid driver imports the dmabufs exported by virtio-gpu. Note that dma_buf_vmap() does its own vmap counting, so it's not needed to take care of it in the driver.

2018-09-25drm/virtio: fix DRM_FORMAT_* handlingGerd Hoffmann
Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order mode_config bit so drm_mode_addfb() asks for the correct format code. Both DRM_FORMAT_* and VIRTIO_GPU_FORMAT_* are defined to be little endian, so using a different mapping on bigendian machines is wrong. It's there because of broken drm_mode_addfb() behavior. So with drm_mode_addfb() being fixed we can fix this too. While wading through the code I've noticed we have a little issue in virtio: We attach a format to the bo when it is created (DRM_IOCTL_MODE_CREATE_DUMB), not when we map it as framebuffer (DRM_IOCTL_MODE_ADDFB). Easy way out: Support a single format only. Pick DRM_FORMAT_HOST_XRGB8888, it is the only one actually used in practice. Drop unused mappings in virtio_gpu_translate_format(). With this patch applied both ADDFB and ADDFB2 ioctls work correctly in the virtio-gpu.ko driver on big endian machines. Without the patch only ADDFB (which still seems to be used by the majority of userspace) works correctly.

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch.

2018-05-18drm/virtio: Place GEM BOs in drm_framebufferDaniel Stone
Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those.

2018-04-25drm/virtio: fix mode_valid's return typeLuc Van Oostenryck
The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it. Fix this by using 'enum drm_mode_status' in the driver too.
