2022-09-29drm/amd/display: Prevent OTG shutdown during PSR SULeo Li
[Why] Enabling Z10 optimizations allows DMUB to disable the OTG during PSR link-off. This theoretically saves power by putting more of the display hardware to sleep. However, we observe that with PSR SU, it causes visual artifacts, higher power usage, and potential system hang. This is partly due to an odd behavior with the VStartup interrupt used to signal DRM vblank events. If the OTG is toggled on/off during a PSR link on/off cycle, the vstartup interrupt fires twice in quick succession. This generates incorrectly timed vblank events. Additionally, it can cause cursor updates to generate visual artifacts. Note that this is not observed with PSR1 since PSR is fully disabled when there are vblank event requestors. Cursor updates are also artifact-free, likely because there are no selectively-updated (SU) frames that can generate artifacts. [How] A potential solution is to disable z10 idle optimizations only when fast updates (flips & cursor updates) are committed. A mechanism to do so would require some thoughtful design. Let's just disable idle optimizations for PSR2 for now.

2022-09-27drm/amdgpu: Add amdgpu suspend-resume code path under SRIOVBokun Zhang
- Under SRIOV, we need to send REQ_GPU_FINI to the hypervisor during the suspend time. Furthermore, we cannot request a mode 1 reset under SRIOV as VF. Therefore, we will skip it as it is called in suspend_noirq() function. - In the resume code path, we need to send REQ_GPU_INIT to the hypervisor and also resume PSP IP block under SRIOV.

2022-09-24Merge branch 'for-6.0/dax' into libnvdimm-fixesDan Williams
Pick up another "Soft Reservation" fix for v6.0-final on top of some straggling nvdimm fixes that missed v5.19.
2022-09-24devdax: Fix soft-reservation memory descriptionDan Williams
The "hmem" platform-devices that are created to represent the platform-advertised "Soft Reserved" memory ranges end up inserting a resource that causes the iomem_resource tree to look like this: 340000000-43fffffff : hmem.0 340000000-43fffffff : Soft Reserved 340000000-43fffffff : dax0.0 This is because insert_resource() reparents ranges when they completely intersect an existing range. This matters because code that uses region_intersects() to scan for a given IORES_DESC will only check that top-level 'hmem.0' resource and not the 'Soft Reserved' descendant. So, to support EINJ (via einj_error_inject()) to inject errors into memory hosted by a dax-device, be sure to describe the memory as IORES_DESC_SOFT_RESERVED. This is a follow-on to: commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP") ...that fixed EINJ support for "Soft Reserved" ranges in the first instance.

Dmitrii, Fangrui, and Mashahiro note: Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2. Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g specified in order for -gsplit-dwarf to work at all. -gsplit-dwarf has been mutually exclusive with -g since support for CONFIG_DEBUG_INFO_SPLIT was introduced in commit 866ced950bcd ("kbuild: Support split debug info v4") I don't think it ever needed to be.

2022-09-23io_uring: ensure that cached task references are always put on exitJens Axboe
io_uring caches task references to avoid doing atomics for each of them per request. If a request is put from the same task that allocated it, then we can maintain a per-ctx cache of them. This obviously relies on io_uring always pruning caches in a reliable way, and there's currently a case off io_uring fd release where we can miss that. One example is a ring setup with IOPOLL, which relies on the task polling for completions, which will free them. However, if such a task submits a request and then exits or closes the ring without reaping the completion, then ring release will reap and put. If release happens from that very same task, the completed request task refs will get put back into the cache pool. This is problematic, as we're now beyond the point of pruning caches. Manually drop these caches after doing an IOPOLL reap. This releases references from the current task, which is enough. If another task happens to be doing the release, then the caching will not be triggered and there's no issue.

2022-09-24certs: make system keyring depend on built-in x509 parserMasahiro Yamada
Commit e90886291c7c ("certs: make system keyring depend on x509 parser") is not the right fix because x509_load_certificate_list() can be modular. The combination of CONFIG_SYSTEM_TRUSTED_KEYRING=y and CONFIG_X509_CERTIFICATE_PARSER=m still results in the following error: LD .tmp_vmlinux.kallsyms1 ld: certs/system_keyring.o: in function `load_system_certificate_list': system_keyring.c:(.init.text+0x8c): undefined reference to `x509_load_certificate_list' make: *** [Makefile:1169: vmlinux] Error 1 Fixes: e90886291c7c ("certs: make system keyring depend on x509 parser") Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Adam Borowski <kilobyte@angband.pl>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core fixes from Greg KH: "Here are two tiny driver core fixes for 6.0-rc7 that resolve some oft-reported problems. The first is a revert of the "fw_devlink.strict=1" default option that we keep trying to enable, but we keep finding platforms that this just breaks everything on. So again, we need it reverted and hopefully it can be worked on in future releases. The second is a sysfs file-size bugfix that resolves an issue that many people are starting to hit as the fix it is fixing also was backported to stable kernels. The util-linux developers are starting to get bugreports about sysfs files that contain no data because of this problem, and this fix which has been in linux-next in the bitfield tree for a long time, resolves it. I'm submitting it here as it needs to be merged for 6.0-final, not for 6.1-rc1. Both of these have been in linux-next with no reported issues, only reports were that these fixed problems" * tag 'driver-core-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES Revert "driver core: Set fw_devlink.strict=1 by default"
