DP 2.0 UHBR link rates always use 128b/132b channel encoding, which has a different data bandwidth efficiency from 8b/10b. The computation is slightly convoluted due to the units we use; this is all explained in the added comment. v2: Clarified comment (Manasi) Reviewed-by:

The MST code uses actual link rates in the limits struct, while the DP code in general uses indexes to the ->common_rates[] array. Fix the confusion by using actual link rate values everywhere. This is a better abstraction than some obscure index. Rename the struct members while at it to ensure all the places are covered. Reviewed-by:

Users reported that after commit 2bbd6dba ("drm/i915: Try to use fast+narrow link on eDP again and fall back to the old max strategy on failure"), the screen starts to have wobbly effect. Commit a5c936ad ("drm/i915/dp: Use slow and wide link training for everything") doesn't help either, that means the affected eDP 1.2 panels only work with max params. So use max params for panels < eDP 1.4 as Windows does to solve the issue. v3: - Do the eDP rev check in intel_edp_init_dpcd() v2: - Check eDP 1.4 instead of DPCD 1.1 to apply max params Cc: stable@vger.kernel.org Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/3714 Fixes: 2bbd6dba ("drm/i915: Try to use fast+narrow link on eDP again and fall back to the old max strategy on failure") Fixes: a5c936ad ("drm/i915/dp: Use slow and wide link training for everything") Suggested-by:

On ILK+ we current do a nuke right after activating FBC. If my memory isn't playing tricks on me this is actially required if FBC didn't stay disabled for a full frame. In that case the deactivate+reactivate may not invalidate the cfb. I'd have to double chekc to be sure though. So let's keep the nuke, and just extend it backwards to cover all the platforms by doing it a bit higher up. Reviewed-by:

Atm the EFI FB platform driver gets a runtime PM reference for the associated GFX PCI device during probing the EFI FB platform device and releases it only when the platform device gets unbound. When fbcon switches to the FB provided by the PCI device's driver (for instance i915/drmfb), the EFI FB will get only unregistered without the EFI FB platform device getting unbound, keeping the runtime PM reference acquired during the platform device probing. This reference will prevent the PCI driver from runtime suspending the device. Fix this by releasing the RPM reference from the EFI FB's destroy hook, called when the FB gets unregistered. While at it assert that pm_runtime_get_sync() didn't fail. v2: - Move pm_runtime_get_sync() before register_framebuffer() to avoid its race wrt. efifb_destroy()->pm_runtime_put(). (Daniel) - Assert that pm_runtime_get_sync() didn't fail. - Clarify commit message wrt. platform/PCI device/driver and driver removal vs. device unbinding.

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.
