UAPI Changes: - Add I915_MMAP_OFFSET_FIXED On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid type. On devices without local memory, this caching mode is invalid. As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will be used, depending on the object placement on creation. WB will be used when the object can only exist in system memory, WC otherwise. Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888 - Reinstate the mmap ioctl for (already released) integrated Gen12 platforms Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is still to sunset the IOCTL even for integrated and require using mmap_offset. - Reject caching/set_domain IOCTLs on discrete Expected to become immutable property of the BO - Disallow changing context parameters after first use on Gen12 and earlier - Require setting context parameters at creation on platforms after Gen12 Rationale (for both): Allow less dynamic changes to the context to simplify the implementation and avoid user shooting theirselves in the foot. - Drop I915_CONTEXT_PARAM_RINGSIZE Userspace PR for compute-driver has not been merged - Drop I915_CONTEXT_PARAM_NO_ZEROMAP Userspace PR for libdrm / Beignet was never landed - Drop CONTEXT_CLONE API Userspace PR for Mesa was never landed - Drop getparam support for I915_CONTEXT_PARAM_ENGINES Only existed for symmetry wrt. setparam, never used. - Disallow bonding of virtual engines Drop the prep work, no hardware has been released needing it. - (Implicit) Disable gpu relocations Media userspace was the last userspace to still use them. They have converted so performance can be regained with an update.
