Name
drm_gem_cma_prime_vunmap —
unmap a CMA GEM object from the kernel's virtual address space
Synopsis
void drm_gem_cma_prime_vunmap ( | struct drm_gem_object * obj, |
| | void * vaddr); |
Arguments
obj
GEM object
vaddr
kernel virtual address where the CMA GEM object was mapped
Description
This function removes a buffer exported via DRM PRIME from the kernel's
virtual address space. This is a no-op because CMA buffers cannot be
unmapped from kernel space. Drivers using the CMA helpers should set this
as their DRM driver's ->gem_prime_vunmap callback.
