config DRM_XEN_FRONTEND_CMA
bool "Use DRM CMA to allocate dumb buffers"
depends on DRM_XEN_FRONTEND
select DRM_KMS_CMA_HELPER
select DRM_GEM_CMA_HELPER
help
Use DRM CMA helpers to allocate display buffers.
This is useful for the use-cases when guest driver needs to
share or export buffers to other drivers which only expect
contiguous buffers.
Note: in this mode driver cannot use buffers allocated
by the backend.
