2020-08-05watchdog: add support for adjusting last known HW keepalive timeTero Kristo1-0/+12
Certain watchdogs require the watchdog only to be pinged within a specific time window, pinging too early or too late cause the watchdog to fire. In cases where this sort of watchdog has been started before kernel comes up, we must adjust the watchdog keepalive window to match the actually running timer, so add a new driver API for this purpose.

2020-08-05docs: watchdog: codify ident.options as superset of possible status flagsAhmad Fatoum1-1/+1
The FIXME comment has been in-tree since the very first git commit. The described behavior has been since relied on by some userspace, e.g. the util-linux wdctl command and has been ignored by some kernelspace, like the f71808e_wdt driver. The functionality is useful to have to be able to differentiate between a driver that doesn't support WDIOF_CARDRESET and one that does, but hasn't had a watchdog reset, thus drop the FIXME to encourage drivers adopting this convention.

Pull x86 fsgsbase from Thomas Gleixner: "Support for FSGSBASE. Almost 5 years after the first RFC to support it, this has been brought into a shape which is maintainable and actually works. This final version was done by Sasha Levin who took it up after Intel dropped the ball. Sasha discovered that the SGX (sic!) offerings out there ship rogue kernel modules enabling FSGSBASE behind the kernels back which opens an instantanious unpriviledged root hole. The FSGSBASE instructions provide a considerable speedup of the context switch path and enable user space to write GSBASE without kernel interaction. This enablement requires careful handling of the exception entries which go through the paranoid entry path as they can no longer rely on the assumption that user GSBASE is positive (as enforced via prctl() on non FSGSBASE enabled systemn). All other entries (syscalls, interrupts and exceptions) can still just utilize SWAPGS unconditionally when the entry comes from user space. Converting these entries to use FSGSBASE has no benefit as SWAPGS is only marginally slower than WRGSBASE and locating and retrieving the kernel GSBASE value is not a free operation either. The real benefit of RD/WRGSBASE is the avoidance of the MSR reads and writes. The changes come with appropriate selftests and have held up in field testing against the (sanitized) Graphene-SGX driver" * tag 'x86-fsgsbase-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) x86/fsgsbase: Fix Xen PV support x86/ptrace: Fix 32-bit PTRACE_SETREGS vs fsbase and gsbase selftests/x86/fsgsbase: Add a missing memory constraint selftests/x86/fsgsbase: Fix a comment in the ptrace_write_gsbase test selftests/x86: Add a syscall_arg_fault_64 test for negative GSBASE selftests/x86/fsgsbase: Test ptracer-induced GS base write with FSGSBASE selftests/x86/fsgsbase: Test GS selector on ptracer-induced GS base write Documentation/x86/64: Add documentation for GS/FS addressing mode x86/elf: Enumerate kernel FSGSBASE capability in AT_HWCAP2 x86/cpu: Enable FSGSBASE on 64bit by default and add a chicken bit x86/entry/64: Handle FSGSBASE enabled paranoid entry/exit x86/entry/64: Introduce the FIND_PERCPU_BASE macro x86/entry/64: Switch CR3 before SWAPGS in paranoid entry x86/speculation/swapgs: Check FSGSBASE in enabling SWAPGS mitigation x86/process/64: Use FSGSBASE instructions on thread copy and ptrace x86/process/64: Use FSBSBASE in switch_to() if available x86/process/64: Make save_fsgs_for_kvm() ready for FSGSBASE x86/fsgsbase/64: Enable FSGSBASE instructions in helper functions x86/fsgsbase/64: Add intrinsics for FSGSBASE instructions x86/cpu: Add 'unsafe_fsgsbase' to enable CR4.FSGSBASE ...

A larger driver for the Tegra memory controller that was accidentally missed for v5.8 is now added. - reset controllers: Only minor updates to drivers/reset this time - firmware: The "turris mox" firmware driver gains support for signed firmware blobs The tegra firmware driver gets extended to export some debug information Various updates to i.MX firmware drivers, mostly cosmetic - ARM SCMI/SCPI: A new mechanism for platform notifications is added, among a number of minor changes. - optee: Probing of the TEE bus is rewritten to better support detection of devices that depend on the tee-supplicant user space. A new firmware based trusted platform module (fTPM) driver is added based on OP-TEE - SoC attributes: A new driver is added to provide a generic soc_device for identifying a machine through the SMCCC ARCH_SOC_ID firmware interface rather than by probing SoC family specific registers. The series also contains some cleanups to the common soc_device code. There are also a number of updates to SoC specific drivers, the main ones are: - Mediatek cmdq driver gains a few in-kernel interfaces - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding support for additional SoC variants - The Qualcomm GENI core code gains interconnect path voting and performance level support, and integrating this into a number of device drivers. - A new driver for Samsung Exynos5800 voltage coupler for - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC specific device drivers - Updates to the TI K3 Ring Accelerator driver" * tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (164 commits) soc: qcom: geni: Fix unused label warning soc: qcom: smd-rpm: Fix kerneldoc memory: jz4780_nemc: Only request IO memory the driver will use soc: qcom: pdr: Reorder the PD state indication ack MAINTAINERS: Add Git repository for memory controller drivers memory: brcmstb_dpfe: Fix language typo memory: samsung: exynos5422-dmc: Correct white space issues memory: samsung: exynos-srom: Correct alignment memory: pl172: Enclose macro argument usage in parenthesis memory: of: Correct kerneldoc memory: omap-gpmc: Fix language typo memory: omap-gpmc: Correct white space issues memory: omap-gpmc: Use 'unsigned int' for consistency memory: omap-gpmc: Enclose macro argument usage in parenthesis memory: omap-gpmc: Correct kerneldoc memory: mvebu-devbus: Align with open parenthesis memory: mvebu-devbus: Add missing braces to all arms of if statement memory: bt1-l2-ctl: Add blank lines after declarations soc: TI knav_qmss: make symbol 'knav_acc_range_ops' static firmware: ti_sci: Replace HTTP links with HTTPS ones ...

Usage is mostly seamless to tooling, as the pre-existing LBR features are kept, but there's a couple of advantages under the hood, such as faster context-switching, faster LBR reads, cleaner exposure of LBR features to guest kernels, etc. ( Since architectural LBRs are supported via XSAVE, there's related changes to the x86 FPU code as well. ) ftrace/perf updates: - Add support to add a text poke event to record changes to kernel text (i.e. self-modifying code) in order to support tracers like Intel PT decoding through jump labels, kprobes and ftrace trampolines.
