[PATCH 08/43] drm/fbdev: Add fbdev-shmem

2024-03-12 Thread Thomas Zimmermann
Add an fbdev emulation for SHMEM-based memory managers. The code is similar to fbdev-generic, but does not require an addition shadow buffer for mmap(). Fbdev-shmem operates directly on the buffer object's SHMEM pages. Fbdev's deferred-I/O mechanism updates the hardware state on write operations.
