2025-02-05ACPI: PRM: Remove unnecessary strict handler address checksAubrey Li
Commit 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM handler and context") added unnecessary strict handler address checks, causing the PRM module to fail in translating memory error addresses. Both static data buffer address and ACPI parameter buffer address may be NULL if they are not needed, as described in section 4.1.2 PRM Handler Information Structure of Platform Runtime Mechanism specification [1]. Here are two examples from real hardware: ----PRMT.dsl---- - staic data address is not used [10Ch 0268 2] Revision : 0000 [10Eh 0270 2] Length : 002C [110h 0272 16] Handler GUID : F6A58D47-E04F-4F5A-86B8-2A50D4AA109B [120h 0288 8] Handler address : 0000000065CE51F4 [128h 0296 8] Satic Data Address : 0000000000000000 [130h 0304 8] ACPI Parameter Address : 000000006522A718 - ACPI parameter address is not used [1B0h 0432 2] Revision : 0000 [1B2h 0434 2] Length : 002C [1B4h 0436 16] Handler GUID : 657E8AE6-A8FC-4877-BB28-42E7DE1899A5 [1C4h 0452 8] Handler address : 0000000065C567C8 [1CCh 0460 8] Satic Data Address : 000000006113FB98 [1D4h 0468 8] ACPI Parameter Address : 0000000000000000 Fixes: 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM handler and context") Reported-and-tested-by: Shi Liu <aurelianliu@tencent.com> Cc: All applicable <stable@vger.kernel.org> Signed-off-by: Aubrey Li <aubrey.li@linux.intel.com> Link: https://uefi.org/sites/default/files/resources/Platform%20Runtime%20Mechanism%20-%20with%20legal%20notice.pdf # [1] Reviewed-by: Koba Ko <kobak@nvidia.com> Acked-by: Ard Biesheuvel <ardb@kernel.org> Link: https://patch.msgid.link/20250126022250.3014210-1-aubrey.li@linux.intel.com [ rjw: Minor changelog edits ] Signed-off-by: Rafael J.

2025-02-05ACPI: property: Fix return value for nval == 0 in acpi_data_prop_read()Andy Shevchenko
While analysing code for software and OF node for the corner case when caller asks to read zero items in the supposed to be an array of values I found that ACPI behaves differently to what OF does, i.e. 1. It returns -EINVAL when caller asks to read zero items from integer array, while OF returns 0, if no other errors happened. 2. It returns -EINVAL when caller asks to read zero items from string array, while OF returns -ENODATA, if no other errors happened. Amend ACPI implementation to follow what OF does.

2025-02-05cpufreq: airoha: modify CONFIG_OF dependencyArnd Bergmann
Compile-testing without CONFIG_OF leads to a harmless build warning: drivers/cpufreq/airoha-cpufreq.c:109:34: error: 'airoha_cpufreq_match_list' defined but not used [-Werror=unused-const-variable=] 109 | static const struct of_device_id airoha_cpufreq_match_list[] __initconst = { | ^~~~~~~~~~~~~~~~~~~~~~~~~ It would be possible to mark the variable as __maybe_unused to shut up that warning, but a Kconfig dependency seems more appropriate as this still allows build testing in allmodconfig and randconfig builds on all architectures. An earlier commit, b865a8404642 ("cpufreq: airoha: Depends on OF"), tried to fix it incorrectly. ARCH_AIROHA already requires CONFIG_OF, so this change does nothing, and the dependency is still missing for the COMPILE_TEST case. Fix it properly.

Depending on whether the caller relies on %rbx to be preserved across the call or not, this clobbering might result in an early crash of the system.

2025-02-06kbuild: keep symbols for symbol_get() even with CONFIG_TRIM_UNUSED_KSYMSMasahiro Yamada
Linus observed that the symbol_request(utf8_data_table) call fails when CONFIG_UNICODE=y and CONFIG_TRIM_UNUSED_KSYMS=y. symbol_get() relies on the symbol data being present in the ksymtab for symbol lookups. However, EXPORT_SYMBOL_GPL(utf8_data_table) is dropped due to CONFIG_TRIM_UNUSED_KSYMS, as no module references it in this case. Probably, this has been broken since commit dbacb0ef670d ("kconfig option for TRIM_UNUSED_KSYMS"). This commit addresses the issue by leveraging modpost. Symbol names passed to symbol_get() are recorded in the special .no_trim_symbol section, which is then parsed by modpost to forcibly keep such symbols. The .no_trim_symbol section is discarded by the linker scripts, so there is no impact on the size of the final vmlinux or modules. This commit cannot resolve the issue for direct calls to __symbol_get() because the symbol name is not known at compile-time. Although symbol_get() may eventually be deprecated, this workaround should be good enough meanwhile.

2025-02-06scripts/Makefile.extrawarn: Do not show clang's non-kprintf warnings at W=1Nathan Chancellor
Clang's -Wformat-overflow and -Wformat-truncation have chosen to check '%p' unlike GCC but it does not know about the kernel's pointer extensions in lib/vsprintf.c, so the developers split that part of the warning out for the kernel to disable because there will always be false positives. Commit 908dd508276d ("kbuild: enable -Wformat-truncation on clang") did disabled these warnings but only in a block that would be called when W=1 was not passed, so they would appear with W=1. Move the disabling of the non-kprintf warnings to a block that always runs so that they are never seen, regardless of warning level.

2025-02-05dt-bindings: soc: samsung: usi: add USIv1 and samsung,exynos8895-usiIvaylo Ivanov
Add new constants for choosing the additional USIv1 configuration modes in device tree. Those are further used in the USI driver to figure out which value to write into SW_CONF register. Modify the current USI IP-core bindings to include information about USIv1 and a compatible for exynos8895. In the original bindings commit, protocol mode definitions were named with the version of the supported USI (in this case, V2) with the idea of leaving enough room in the future for other versions of this block. This, however, is not how the modes should be modelled. The modes are not version specific and you should not be able to tell USI which version of a mode to use - that has to be handled in the driver - thus encoding this information in the binding is meaningless. Only one constant per mode is needed, so while we're at it, add new constants with the prefix USI_MODE and mark the old ones as depracated.

Currently, there are several files in drm/amd/display that aim to have a higher -Wframe-larger-than value to avoid instances of that warning with a lower value from the user's configuration. However, with the way that it is currently implemented, it does not respect the user's request via CONFIG_FRAME_WARN for a higher stack frame limit, which can cause pain when new instances of the warning appear and break the build due to CONFIG_WERROR. Adjust the logic to switch from a hard coded -Wframe-larger-than value to only using the value as a minimum clamp and deferring to the requested value from CONFIG_FRAME_WARN if it is higher.

2025-02-04gpio: pca953x: Improve interrupt supportMark Tomlinson
The GPIO drivers with latch interrupt support (typically types starting with PCAL) have interrupt status registers to determine which particular inputs have caused an interrupt. Unfortunately there is no atomic operation to read these registers and clear the interrupt. Clearing the interrupt is done by reading the input registers. The code was reading the interrupt status registers, and then reading the input registers. If an input changed between these two events it was lost. The solution in this patch is to revert to the non-latch version of code, i.e. remembering the previous input status, and looking for the changes. This system results in no more I2C transfers, so is no slower. The latch property of the device still means interrupts will still be noticed if the input changes back to its initial state.
