Tyr buffer objects are shmem-backed, so the driver should use drm::gem::shmem::Object<BoData> as its GEM object type instead of the base drm::gem::Object<BoData> type. Switching to the shmem GEM object type matches how Tyr allocates and manages its buffer objects, and uses the shmem-specific GEM abstraction provided by the DRM Rust bindings. Select RUST_DRM_GEM_SHMEM_HELPER to ensure the required helpers are available when DRM_TYR is enabled.

Rust DRM driver for ARM Mali CSF-based GPUs.
|
|
|
|
This driver is for Mali (or Immortalis) Valhall Gxxx GPUs.
|
|
|
|
Note that the Mali-G68 and Mali-G78, while Valhall architecture, will
|
|
be supported with the panfrost driver as they are not CSF GPUs.
|
|
|
|
if M is selected, the module will be called tyr. This driver is work
|
|
in progress and may not be functional.
