DMA-BUF requires that each device that accesses a DMA-BUF attaches to it
separately. To do so the host1x_bo_pin() and host1x_bo_unpin() functions
need to be reimplemented so that they can return a mapping, which either
represents an attachment or a map of the driver's own GEM object.

drm/tegra: Implement syncpoint wait UAPI2021-08-10T15:04:05+00:00Mikko Perttunenmperttunen@nvidia.com2021-06-10T11:04:53+00:00urn:sha1:44e961381354df6db92065be3ba2e608c1838b3e
Implement new syncpoint wait UAPI. This is different from the
legacy one in taking an absolute timestamp in line with modern
DRM conventions.

Implement the non-submission parts of the new UAPI, including
channel management and memory mapping. The UAPI is under the
CONFIG_DRM_TEGRA_STAGING config flag for now.
