2021-02-23drm/amd/display: Add vupdate_no_lock interrupts for DCN2.1Rodrigo Siqueira1-0/+22
When run igt@kms_vrr in a device that uses DCN2.1 architecture, we noticed multiple failures. Furthermore, when we tested a VRR demo, we noticed a system hang where the mouse pointer still works, but the entire system freezes; in this case, we don't see any dmesg warning or failure messages kernel. This happens due to a lack of vupdate_no_lock interrupt, making the userspace wait eternally to get the event back. For fixing this issue, we need to add the vupdate_no_lock interrupt in the interrupt list.

2021-02-23drm/amdkfd: Cleanup kfd_process if init_cwsr_apu failsFelix Kuehling1-4/+10
If init_cwsr_apu fails, we currently leave the kfd_process structure in place anyway. The next kfd_open will then succeed, using the existing kfd_process structure. Fix that by cleaning up the kfd_process after a failure in init_cwsr_apu.

2021-02-22doc: use KCFLAGS instead of EXTRA_CFLAGS to pass flags from command lineMasahiro Yamada1-1/+1
You should use KCFLAGS to pass additional compiler flags from the command line. Using EXTRA_CFLAGS is wrong. EXTRA_CFLAGS is supposed to specify flags applied only to the current Makefile (and now deprecated in favor of ccflags-y). It is still used in arch/mips/kvm/Makefile (and possibly in external modules too). Passing EXTRA_CFLAGS from the command line overwrites it and breaks the build. I also fixed drivers/gpu/drm/tilcdc/Makefile because commit 816175dd1fd7 ("drivers/gpu/drm/tilcdc: Makefile, only -Werror when no -W* in EXTRA_CFLAGS") was based on the same misunderstanding.

Pull KVM updates from Paolo Bonzini: "x86: - Support for userspace to emulate Xen hypercalls - Raise the maximum number of user memslots - Scalability improvements for the new MMU. Instead of the complex "fast page fault" logic that is used in mmu.c, tdp_mmu.c uses an rwlock so that page faults are concurrent, but the code that can run against page faults is limited. Right now only page faults take the lock for reading; in the future this will be extended to some cases of page table destruction.

2021-02-20drm/i915/vbt: update DP max link rate tableLee Shawn C2-21/+60
According to Bspec #20124, max link rate table for DP was updated at BDB version 230. Max link rate can support upto UHBR. After migrate to BDB v230, the definition for LBR, HBR2 and HBR3 were changed. For backward compatibility. If BDB version was from 216 to 229. Driver have to follow original rule to configure DP max link rate value from VBT. v2: split the mapping table to two for old and new BDB definition. v3: return link rate instead of assigning it. v4: remove the useless variable.
