This change adds configurable memattr that hardware fb implementation can set to get the memory mapping type it requires: - Add new flag FB_FLAG_MEMATTR that indicates that framebuffer driver overrides default memattr - Add new field fb_memattr to struct fb_info to specify requested memattr Reviewed by: ray Differential Revision: https://reviews.freebsd.org/D8064 |
