UAPI Changes: - Make context persistence optional Allow userspace to tie the context lifetime to FD lifetime, effectively allowing Ctrl-C killing of a process to also clean up the hardware immediately. Compute changes: https://github.com/intel/compute-runtime/pull/228 The compute driver is shipping in Ubuntu. uAPI acked by Mesa folks. - Put future HW and their uAPIs under STAGING & BROKEN Introduces DRM_I915_UNSTABLE Kconfig menu for working on the new uAPI for future HW in upstream. We already disable driver loading by default the platform is deemed ready. This is a second level of protection based on compile time switch (STAGING & BROKEN). - Under DRM_I915_UNSTABLE: Add the fake lmem region on iGFX Fake local memory region on integrated GPU through cmdline: memmap=2G$16G i915.fake_lmem_start=0x400000000 Currently allows testing non-mappable GGTT behavior and running kernel selftest for local memory.

drm/todo: Clarify situation around fbdev and defio

2019-10-28T09:08:46Z

The TODO item is misleading and makes it seem as if fbdev emulation cannot be used with SHMEM. Rephrase the text to describe the current situation more correctly.
