This reverts commita69b0e855d. This patchset doesn't meet the UAPI requirements set out in [1] for the DRM subsystem. Once the userspace component is reviewed and ready for merge we can try again.

|
|
The Sync File Framework adds explicit syncronization via
|
|
userspace. It enables send/receive 'struct dma_fence' objects to/from
|
|
userspace via Sync File fds for synchronization between drivers via
|
|
userspace components. It has been ported from Android.
|
|
|
|
The first and main user for this is graphics in which a fence is
|
|
associated with a buffer. When a job is submitted to the GPU a fence
|
|
is attached to the buffer and is transferred via userspace, using Sync
|
|
Files fds, to the DRM driver for example. More details at
|
|
Documentation/driver-api/sync_file.rst.

|
|
A sync object driver that uses a 32bit counter to coordinate

synchronization. Useful when there is no hardware primitive backing

the synchronization.

WARNING: improper use of this can result in deadlocking kernel
|
|
drivers from userspace. Intended for test and debug only.
