2022-10-24drm/i915: Fix compute pre-emption w/a to apply to compute enginesJohn Harrison
An earlier patch added support for compute engines. However, it missed enabling the anti-pre-emption w/a for the new engine class. So move the 'compute capable' flag earlier and use it for the pre-emption w/a test.

2022-10-24drm/i915/guc: Limit scheduling properties to avoid overflowJohn Harrison
GuC converts the pre-emption timeout and timeslice quantum values into clock ticks internally. That significantly reduces the point of 32bit overflow. On current platforms, worst case scenario is approximately 110 seconds. Rather than allowing the user to set higher values and then get confused by early timeouts, add limits when setting these values. v2: Add helper functions for clamping (review feedback from Tvrtko). v3: Add a bunch of BUG_ON range checks in addition to the checks already in the clamping functions (Tvrtko) Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221006213813.1563435-2-John.C.Harrison@Intel.com
2022-10-24drm/client: Switch drm_client_buffer_delete() to unlocked drm_gem_vunmapDmitry Osipenko
The drm_client_buffer_delete() wasn't switched to unlocked GEM vunmapping by accident when rest of drm_client code transitioned to the unlocked variants of the vmapping functions. Make drm_client_buffer_delete() use the unlocked variant. This fixes lockdep warning splat about missing reservation lock when framebuffer is released.

2022-10-24drm/bridge: it6505: Improve synchronization between extcon subsystemPin-yen Lin
Originally, the it6505 relies on a short sleep in the IRQ handler and a long sleep to make sure it6505->lane_swap and it6505->lane_count is configured in it6505_extcon_work and it6505_detect, respectively. Use completion and additional DPCD read to remove the unnecessary waits, and use a different lock for it6505_extcon_work and the threaded IRQ handler because they no longer need to run exclusively. The wait time of the completion is usually less than 10ms in local experiments, but leave it larger here just in case.

Be consistent in whether we flag a full modeset or a fastset for the pipe. intel_modeset_all_pipes() would seem to be the only codepath not getting this right. The other case is when we flag the fastset initially, currently we just clear the mode_changed flag and set the update_pipe flag.

2022-10-22drm/i915: Activate DRRS after state readoutVille Syrjälä
On BDW+ we have just the one set of DP M/N registers. The values we write into said registers depends on whether we want DRRS to be in high or low gear. This causes issues for the state checker which currently has to assume either set of M/N (high or low refresh rate) values may appear there. That sort of works for M/N itself, but all other values derived from the M/N (dotclock, pixel rate) are not handled correctly, leading to potential for state checker mismatches. Let's avoid all those problems by simply keeping DRRS in high gear until the state checker has done its hardware state readout. Note that hitting this issue presumable became very hard after commit 1b333c679a0f ("drm/i915: Do DRRS disable/enable during pre/post_plane_update()") since the state check would have to laze about for one full second (delay used by intel_drrs_schedule_work()) to see the low refresh rate. But it is still theoretically possible.

2022-10-22KVM: x86: Add compat handler for KVM_X86_SET_MSR_FILTERAlexander Graf
The KVM_X86_SET_MSR_FILTER ioctls contains a pointer in the passed in struct which means it has a different struct size depending on whether it gets called from 32bit or 64bit code. This patch introduces compat code that converts from the 32bit struct to its 64bit counterpart which then gets used going forward internally. With this applied, 32bit QEMU can successfully set MSR bitmaps when running on 64bit kernels.

2022-10-22KVM: x86: Copy filter arg outside kvm_vm_ioctl_set_msr_filter()Alexander Graf
In the next patch we want to introduce a second caller to set_msr_filter() which constructs its own filter list on the stack. Refactor the original function so it takes it as argument instead of reading it through copy_from_user().

2022-10-21x86/fpu: Fix copy_xstate_to_uabi() to copy init states correctlyChang S. Bae
When an extended state component is not present in fpstate, but in init state, the function copies from init_fpstate via copy_feature(). But, dynamic states are not present in init_fpstate because of all-zeros init states. Then retrieving them from init_fpstate will explode like this: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... RIP: 0010:memcpy_erms+0x6/0x10 ? __copy_xstate_to_uabi_buf+0x381/0x870 fpu_copy_guest_fpstate_to_uabi+0x28/0x80 kvm_arch_vcpu_ioctl+0x14c/0x1460 [kvm] ? __this_cpu_preempt_check+0x13/0x20 ? vmx_vcpu_put+0x2e/0x260 [kvm_intel] kvm_vcpu_ioctl+0xea/0x6b0 [kvm] ? kvm_vcpu_ioctl+0xea/0x6b0 [kvm] ? __fget_light+0xd4/0x130 __x64_sys_ioctl+0xe3/0x910 ? debug_smp_processor_id+0x17/0x20 ? fpregs_assert_state_consistent+0x27/0x50 do_syscall_64+0x3f/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd Adjust the 'mask' to zero out the userspace buffer for the features that are not available both from fpstate and from init_fpstate. The dynamic features depend on the compacted XSAVE format. Ensure it is enabled before reading XCOMP_BV in init_fpstate.
