2022-06-13arm64: dts: meson: add gpio-fan control to GS-King-XFurkan Kardame1-0/+25
GS-King-X has a single speed GPIO fan which is always-on by default. If we add controls for the fan and a trip point, the fan stays off most of the time, reducing background noise from the unit.

2022-06-13perf/x86/amd/uncore: Add PerfMonV2 RDPMC assignmentsSandipan Das1-0/+10
The current RDPMC assignment scheme maps four DF PMCs and six L3 PMCs from index 6 to 15. If AMD Performance Monitoring Version 2 (PerfMonV2) is supported, there may be additional DF counters available which are mapped starting from index 16 i.e. just after the L3 counters. Update the RDPMC assignments accordingly.

Use the update_attrs attribute group introduced by commit f3a3a8257e5a ("perf/core: Add attr_groups_update into struct pmu") and the is_visible() callback to populate the family specifc attributes for uncore events. The changes apply to attributes that are unique to families such as slicemask for Family 17h and coreid for Family 19h. The addition of common attributes such as event and umask, whose formats change across families, remain unchanged.

If AMD Performance Monitoring Version 2 (PerfMonV2) is supported, the number of available counters for a given uncore PMU may not be fixed across families and models and has to be determined at runtime.

2022-06-13x86/events/intel/ds: Enable large PEBS for PERF_SAMPLE_WEIGHT_TYPELike Xu1-1/+2
All the information required by the PERF_SAMPLE_WEIGHT is available in the pebs record. Thus large PEBS could be enabled for PERF_SAMPLE_WEIGHT sample type to save PMIs overhead until other non-compatible flags such as PERF_SAMPLE_DATA_PAGE_SIZE (due to lack of munmap tracking) stop it. To cover new weight extension, add PERF_SAMPLE_WEIGHT_TYPE to the guardian LARGE_PEBS_FLAGS.

2022-06-13sched: Fix balance_push() vs __sched_setscheduler()Peter Zijlstra2-3/+38
The purpose of balance_push() is to act as a filter on task selection in the case of CPU hotplug, specifically when taking the CPU out. It does this by (ab)using the balance callback infrastructure, with the express purpose of keeping all the unlikely/odd cases in a single place. In order to serve its purpose, the balance_push_callback needs to be (exclusively) on the callback list at all times (noting that the callback always places itself back on the list the moment it runs, also noting that when the CPU goes down, regular balancing concerns are moot, so ignoring them is fine). And here-in lies the problem, __sched_setscheduler()'s use of splice_balance_callbacks() takes the callbacks off the list across a lock-break, making it possible for, an interleaving, __schedule() to see an empty list and not get filtered.

2022-06-13x86/mm: Fix RESERVE_BRK() for older binutilsJosh Poimboeuf3-24/+23
With binutils 2.26, RESERVE_BRK() causes a build failure: /tmp/ccnGOKZ5.s: Assembler messages: /tmp/ccnGOKZ5.s:98: Error: missing ')' /tmp/ccnGOKZ5.s:98: Error: missing ')' /tmp/ccnGOKZ5.s:98: Error: missing ')' /tmp/ccnGOKZ5.s:98: Error: junk at end of line, first unrecognized character is `U' The problem is this line: RESERVE_BRK(early_pgt_alloc, INIT_PGT_BUF_SIZE) Specifically, the INIT_PGT_BUF_SIZE macro which (via PAGE_SIZE's use _AC()) has a "1UL", which makes older versions of the assembler unhappy. Unfortunately the _AC() macro doesn't work for inline asm. Inline asm was only needed here to convince the toolchain to add the STT_NOBITS flag. However, if a C variable is placed in a section whose name is prefixed with ".bss", GCC and Clang automatically set STT_NOBITS. In fact, ".bss..page_aligned" already relies on this trick. So fix the build failure (and simplify the macro) by allocating the variable in C. Also, add NOLOAD to the ".brk" output section clause in the linker script. This is a failsafe in case the ".bss" prefix magic trick ever stops working somehow. If there's a section type mismatch, the GNU linker will force the ".brk" output section to be STT_NOBITS. The LLVM linker will fail with a "section type mismatch" error. Note this also changes the name of the variable from .brk.##name to __brk_##name. The variable names aren't actually used anywhere, so it's harmless.

Pull random number generator fixes from Jason Donenfeld: - A fix for a 5.19 regression for a case in which early device tree initializes the RNG, which flips a static branch. On most plaforms, jump labels aren't initialized until much later, so this caused splats. On a few mailing list threads, we cooked up easy fixes for arm64, arm32, and risc-v. But then things looked slightly more involved for xtensa, powerpc, arc, and mips. And at that point, when we're patching 7 architectures in a place before the console is even available, it seems like the cost/risk just wasn't worth it. So random.c works around it now by checking the already exported `static_key_initialized` boolean, as though somebody already ran into this issue in the past. I'm not super jazzed about that; it'd be prettier to not have to complicate downstream code. But I suppose it's practical. - A few small code nits and adding a missing __init annotation. - A change to the default config values to use the cpu and bootloader's seeds for initializing the RNG earlier. This brings them into line with what all the distros do (Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at least), and moreover will now give us test coverage in various test beds that might have caught the above device tree bug earlier. - A change to WireGuard CI's configuration to increase test coverage around the RNG. - A documentation comment fix to unrelated maintainerless CRC code that I was asked to take, I guess because it has to do with polynomials (which the RNG thankfully no longer uses). * tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: wireguard: selftests: use maximum cpu features and allow rng seeding random: remove rng_has_arch_random() random: credit cpu and bootloader seeds by default random: do not use jump labels before they are initialized random: account for arch randomness in bits random: mark bootloader randomness code as __init random: avoid checking crng_ready() twice in random_init() crc-itu-t: fix typo in CRC ITU-T polynomial comment

2022-06-12drm/bridge: ti-sn65dsi83: Do not cache dsi_lanes and host twiceMarek Vasut1-42/+22
The DSI lane count can be accessed via the dsi device pointer, make use of that. The DSI host pointer is only used in sn65dsi83_host_attach(), move the code around so that the host does not have to be cached in the driver private data. This simplifies the code further. No functional change. This has the added bonus that lt9211, tc358767, sn65dsi83 now use very similar *_mipi_dsi_host_attach() which is ripe for deduplication.

2022-06-12platform/x86: Drop the PMC_ATOM Kconfig optionHans de Goede3-9/+2
The def_bool y PMC_ATOM Kconfig option provides a couple of symbols used by the code enabled by the X86_INTEL_LPSS option and it registers some clocks. These clocks are only registered on Bay Trail, Cherry Trail and Brasswell Intel SoCs and kernels targeting these SoCs must always have the X86_INTEL_LPSS option enabled otherwise many things will not work. Building the PMC_ATOM code on kernels which are not targeting the mentioned SoCs and which do not have the X86_INTEL_LPSS enabled is not useful. This means that we can simplify things by replacing the PMC_ATOM Kconfig option in Makefiles with X86_INTEL_LPSS and then drop the option.

2022-06-12platform/x86: hp-wmi: Resolve WMI query failures on some devicesJorge Lopez1-2/+4
WMI queries fail on some devices where the ACPI method HWMC unconditionally attempts to create Fields beyond the buffer if the buffer is too small, this breaks essential features such as power profiles: CreateByteField (Arg1, 0x10, D008) CreateByteField (Arg1, 0x11, D009) CreateByteField (Arg1, 0x12, D010) CreateDWordField (Arg1, 0x10, D032) CreateField (Arg1, 0x80, 0x0400, D128) In cases where args->data had zero length, ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit offset/length 128/8 exceeds size of target Buffer (128 bits) (20211217/dsopcode-198) was obtained. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit offset/length 136/8 exceeds size of target Buffer (136bits) (20211217/dsopcode-198) The original code created a buffer size of 128 bytes regardless if the WMI call required a smaller buffer or not. This particular behavior occurs in older BIOS and reproduced in OMEN laptops. Newer BIOS handles buffer sizes properly and meets the latest specification requirements. This is the reason why testing with a dynamically allocated buffer did not uncover any failures with the test systems at hand. This patch was tested on several OMEN, Elite, and Zbooks. It was confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN Laptop 15-ek0xxx. No problems were reported when testing on several Elite and Zbooks notebooks.
