In order to improve performance, allow dma-buf clients to

apply cache maintenance to only a subset of a dma-buf.

|
Kernel clients will be able to use the dma_buf_begin_cpu_access_partial
|
|
and dma_buf_end_cpu_access_partial functions to only apply cache
|
|
maintenance to a range within the dma-buf.

help
|
|
The Sync File Framework adds explicit synchronization 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.

help
|
|
Don't pin buffers if the dynamic DMA-buf interface is available on
|
|
both the exporter as well as the importer. This fixes a security
|
|
problem where userspace is able to pin unrestricted amounts of memory
|
|
through DMA-buf.
|
|
This is marked experimental because we don't yet have a consistent
|
|
execution context and memory management between drivers.
