H A D | drm_mipi_dbi.h | b5f636e6 Fri Dec 02 06:56:41 CST 2022 Thomas Zimmermann <tzimmermann@suse.de> drm/mipi-dbi: Prepare framebuffer copy operation in pipe-update helpers
Move the vmap/vunmap blocks from the inner fb_dirty helpers into the MIPI DBI update helpers. The function calls can result in waiting and/or processing overhead. Reduce the penalties by executing the functions once in the outer-most function of the pipe update.
This change also prepares for MIPI DBI for shadow-plane helpers. With shadow-plane helpers, transfer source buffers are mapped into kernel address space automatically.
v2: * keep each driver's existing buffer-mapping patter (Noralf) * zero-initialize iosys_map arrays (Noralf)
