I'm not sure I totally have my head around it but, I guess we could make sure to call invalidate_kernel_vmap_range() in begin_cpu_access() and flush_kernel_vmap_range() in end_cpu_access() rather then exiting out early as we do now? Unless you have better guidance? Worse case we could check CONFIG_CPU_CACHE_VIVT and not register the system-uncached heap. thanks -john _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
