firmware: arm_scmi: Report duplicate opps as firmware bugs

2024-11-12T18:45:25Z

Duplicate opps reported by buggy SCP firmware currently show up as warnings even though the only functional impact is that the level/index remain inaccessible. Make it less scary for the end user by using dev_info instead, along with FW_BUG tag.

Pull arm64 fixes from Will Deacon: "Here is a (hopefully) final round of arm64 fixes for 6.12 that address some user-visible floating point register corruption. Both of the Marks have been working on this for a couple of weeks and we've ended up in a position where SVE is solid but SME still has enough pending issues that the most pragmatic solution for the release and stable backports is to disable the feature. Yes, it's a shame, but the hardware is rare as hen's teeth at the moment and we're better off getting back to a known good state before fixing it all properly. We're also improving the selftests for 6.13 to help avoid merging broken code in the future. Anyway, the good news is that we're removing a lot more code than we're adding. Summary: - Fix handling of SVE traps from userspace on preemptible kernels when converting the saved floating point state into SVE state. - Remove broken support for the SMCCCv1.3 "SVE discard hint" optimisation. - Disable SME support, as the current support code suffers from numerous issues around signal delivery, ptrace access and context-switch which can lead to user-visible corruption of the register state" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Kconfig: Make SME depend on BROKEN for now arm64: smccc: Remove broken support for SMCCCv1.3 SVE discard hint arm64/sve: Discard stale CPU state when handling SVE traps

arm64: smccc: Remove broken support for SMCCCv1.3 SVE discard hint

2024-11-07T11:18:52Z

SMCCCv1.3 added a hint bit which callers can set in an SMCCC function ID (AKA "FID") to indicate that it is acceptable for the SMCCC implementation to discard SVE and/or SME state over a specific SMCCC call. The kernel support for using this hint is broken and SMCCC calls may clobber the SVE and/or SME state of arbitrary tasks, though FPSIMD state is unaffected. The kernel support is intended to use the hint when there is no SVE or SME state to save, and to do this it checks whether TIF_FOREIGN_FPSTATE is set or TIF_SVE is clear in assembly code: | ldr , [, #TSK_TI_FLAGS] | tbnz , #TIF_FOREIGN_FPSTATE, 1f // Any live FP state? | tbnz , #TIF_SVE, 2f // Does that state include SVE? | | 1: orr , , ARM_SMCCC_1_3_SVE_HINT | 2: | << SMCCC call using FID >> This is not safe as-is: (1) SMCCC calls can be made in a preemptible context and preemption can result in TIF_FOREIGN_FPSTATE being set or cleared at arbitrary points in time. Thus checking for TIF_FOREIGN_FPSTATE provides no guarantee. (2) TIF_FOREIGN_FPSTATE only indicates that the live FP/SVE/SME state in the CPU does not belong to the current task, and does not indicate that clobbering this state is acceptable. When the live CPU state is clobbered it is necessary to update fpsimd_last_state.st to ensure that a subsequent context switch will reload FP/SVE/SME state from memory rather than consuming the clobbered state. This and the SMCCC call itself must happen in a critical section with preemption disabled to avoid races. (3) Live SVE/SME state can exist with TIF_SVE clear (e.g. with only TIF_SME set), and checking TIF_SVE alone is insufficient. Remove the broken support for the SMCCCv1.3 SVE saving hint. This is effectively a revert of commits: * cfa7ff959a78 ("arm64: smccc: Support SMCCC v1.3 SVE register saving hint") * a7c3acca5380 ("arm64: smccc: Save lr before calling __arm_smccc_sve_check()") ... leaving behind the ARM_SMCCC_VERSION_1_3 and ARM_SMCCC_1_3_SVE_HINT definitions, since these are simply definitions from the SMCCC specification, and the latter is used in KVM via ARM_SMCCC_CALL_HINTS. If we want to bring this back in future, we'll probably want to handle this logic in C where we can use all the usual FPSIMD/SVE/SME helper functions, and that'll likely require some rework of the SMCCC code and/or its callers.

Pull SoC fixes from Arnd Bergmann: "Where the last set of fixes was mostly drivers, this time the devicetree changes all come at once, targeting mostly the Rockchips, Qualcomm and NXP platforms. The Qualcomm bugfixes target the Snapdragon X Elite laptops, specifically problems with PCIe and NVMe support to improve reliability, and a boot regresion on msm8939. Also for Snapdragon platforms, there are a number of correctness changes in the several platform specific device drivers, but none of these are as impactful. On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants, correcting individual entries in the devicetree that were incorrect and causing the media, video, mmc and spi drivers to misbehave in minor ways. The Arm SCMI firmware driver gets fixes for a use-after-free bug and for correctly parsing firmware information. On the RISC-V side, there are three minor devicetree fixes for starfive and sophgo, again addressing only minor mistakes.

Qualcomm driver fixes for v6.12 The Qualcomm EDAC driver's configuration of interrupts is made optional, to avoid violating security constriants on X Elite platform . The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE, is corrected to handle the case where firmware successfully returns that the interface isn't supported. The GLINK driver and the PMIC GLINK interface is updated to handle buffer allocation issues during initialization of the communication channel. Allocation error handling in the socinfo dirver is corrected, and then the fix is corrected. * tag 'qcom-drivers-fixes-for-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: pmic_glink: Handle GLINK intent allocation rejections rpmsg: glink: Handle rejected intent request better soc: qcom: socinfo: fix revision check in qcom_socinfo_probe() firmware: qcom: scm: Return -EOPNOTSUPP for unsupported SHM bridge enabling EDAC/qcom: Make irq configuration optional firmware: qcom: scm: fix a NULL-pointer dereference firmware: qcom: scm: suppress download mode error soc: qcom: Add check devm_kasprintf() returned value MAINTAINERS: Qualcomm SoC: Match reserved-memory bindings Link: https://lore.kernel.org/r/20241101161455.746290-1-andersson@kernel.org Signed-off-by: Arnd Bergmann

Summary: - Fix handling of POR_EL0 during signal delivery so that pushing the signal context doesn't fail based on the pkey configuration of the interrupted context and align our user-visible behaviour with that of x86. - Fix a bogus pointer being passed to the CPU hotplug code from the Arm SDEI driver. - Re-enable software tag-based KASAN with GCC by using an alternative implementation of '__no_sanitize_address'" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: signal: Improve POR_EL0 handling to avoid uaccess failures firmware: arm_sdei: Fix the input parameter of cpuhp_remove_state() Revert "kasan: Disable Software Tag-Based KASAN with GCC" kasan: Fix Software Tag-Based KASAN with GCC
