git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras Pull EDAC updates from Borislav Petkov: - Add a FRU (Field Replaceable Unit) memory poison manager which collects and manages previously encountered hw errors in order to save them to persistent storage across reboots. Previously recorded errors are "replayed" upon reboot in order to poison memory which has caused said errors in the past. The main use case is stacked, on-chip memory which cannot simply be replaced so poisoning faulty areas of it and thus making them inaccessible is the only strategy to prolong its lifetime. - Add an AMD address translation library glue which converts the reported addresses of hw errors into system physical addresses in order to be used by other subsystems like memory failure, for example. Add support for MI300 accelerators to that library. - igen6: Add support for Alder Lake-N SoC - i10nm: Add Grand Ridge support - The usual fixlets and cleanups * tag 'edac_updates_for_v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: EDAC/versal: Convert to platform remove callback returning void RAS/AMD/FMPM: Fix off by one when unwinding on error RAS/AMD/FMPM: Add debugfs interface to print record entries RAS/AMD/FMPM: Save SPA values RAS: Export helper to get ras_debugfs_dir RAS/AMD/ATL: Fix bit overflow in denorm_addr_df4_np2() RAS: Introduce a FRU memory poison manager RAS/AMD/ATL: Add MI300 row retirement support Documentation: Move RAS section to admin-guide EDAC/versal: Make the bit position of injected errors configurable EDAC/i10nm: Add Intel Grand Ridge micro-server support EDAC/igen6: Add one more Intel Alder Lake-N SoC support RAS/AMD/ATL: Add MI300 DRAM to normalized address translation support RAS/AMD/ATL: Fix array overflow in get_logical_coh_st_fabric_id_mi300() RAS/AMD/ATL: Add MI300 support Documentation: RAS: Add index and address translation section EDAC/amd64: Use new AMD Address Translation Library RAS: Introduce AMD Address Translation Library EDAC/synopsys: Convert to devm_platform_ioremap_resource()

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 FRED support from Thomas Gleixner: "Support for x86 Fast Return and Event Delivery (FRED). FRED is a replacement for IDT event delivery on x86 and addresses most of the technical nightmares which IDT exposes: 1) Exception cause registers like CR2 need to be manually preserved in nested exception scenarios. 2) Hardware interrupt stack switching is suboptimal for nested exceptions as the interrupt stack mechanism rewinds the stack on each entry which requires a massive effort in the low level entry of #NMI code to handle this. 3) No hardware distinction between entry from kernel or from user which makes establishing kernel context more complex than it needs to be especially for unconditionally nestable exceptions like NMI. 4) NMI nesting caused by IRET unconditionally reenabling NMIs, which is a problem when the perf NMI takes a fault when collecting a stack trace. 5) Partial restore of ESP when returning to a 16-bit segment 6) Limitation of the vector space which can cause vector exhaustion on large systems. 7) Inability to differentiate NMI sources FRED addresses these shortcomings by: 1) An extended exception stack frame which the CPU uses to save exception cause registers. This ensures that the meta information for each exception is preserved on stack and avoids the extra complexity of preserving it in software. 2) Hardware interrupt stack switching is non-rewinding if a nested exception uses the currently interrupt stack. 3) The entry points for kernel and user context are separate and GS BASE handling which is required to establish kernel context for per CPU variable access is done in hardware. 4) NMIs are now nesting protected. They are only reenabled on the return from NMI. 5) FRED guarantees full restore of ESP 6) FRED does not put a limitation on the vector space by design because it uses a central entry points for kernel and user space and the CPUstores the entry type (exception, trap, interrupt, syscall) on the entry stack along with the vector number. The entry code has to demultiplex this information, but this removes the vector space restriction. The first hardware implementations will still have the current restricted vector space because lifting this limitation requires further changes to the local APIC. 7) FRED stores the vector number and meta information on stack which allows having more than one NMI vector in future hardware when the required local APIC changes are in place. The series implements the initial FRED support by: - Reworking the existing entry and IDT handling infrastructure to accomodate for the alternative entry mechanism. - Expanding the stack frame to accomodate for the extra 16 bytes FRED requires to store context and meta information - Providing FRED specific C entry points for events which have information pushed to the extended stack frame, e.g. #PF and #DB. - Providing FRED specific C entry points for #NMI and #MCE - Implementing the FRED specific ASM entry points and the C code to demultiplex the events - Providing detection and initialization mechanisms and the necessary tweaks in context switching, GS BASE handling etc. The FRED integration aims for maximum code reuse vs the existing IDT implementation to the extent possible and the deviation in hot paths like context switching are handled with alternatives to minimalize the impact. The low level entry and exit paths are seperate due to the extended stack frame and the hardware based GS BASE swichting and therefore have no impact on IDT based systems. It has been extensively tested on existing systems and on the FRED simulation and as of now there are no outstanding problems" * tag 'x86-fred-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (38 commits) x86/fred: Fix init_task thread stack pointer initialization MAINTAINERS: Add a maintainer entry for FRED x86/fred: Fix a build warning with allmodconfig due to 'inline' failing to inline properly x86/fred: Invoke FRED initialization code to enable FRED x86/fred: Add FRED initialization functions x86/syscall: Split IDT syscall setup code into idt_syscall_init() KVM: VMX: Call fred_entry_from_kvm() for IRQ/NMI handling x86/entry: Add fred_entry_from_kvm() for VMX to handle IRQ/NMI x86/entry/calling: Allow PUSH_AND_CLEAR_REGS being used beyond actual entry code x86/fred: Fixup fault on ERETU by jumping to fred_entrypoint_user x86/fred: Let ret_from_fork_asm() jmp to asm_fred_exit_user when FRED is enabled x86/traps: Add sysvec_install() to install a system interrupt handler x86/fred: FRED entry/exit and dispatch code x86/fred: Add a machine check entry stub for FRED x86/fred: Add a NMI entry stub for FRED x86/fred: Add a debug fault entry stub for FRED x86/idtentry: Incorporate definitions/declarations of the FRED entries x86/fred: Make exc_page_fault() work for FRED x86/fred: Allow single-step trap and NMI when starting a new task x86/fred: No ESPFIX needed when FRED is enabled ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "A large set of updates and features for timers and timekeeping: - The hierarchical timer pull model When timer wheel timers are armed they are placed into the timer wheel of a CPU which is likely to be busy at the time of expiry. This is done to avoid wakeups on potentially idle CPUs. This is wrong in several aspects: 1) The heuristics to select the target CPU are wrong by definition as the chance to get the prediction right is close to zero. 2) Due to #1 it is possible that timers are accumulated on a single target CPU 3) The required computation in the enqueue path is just overhead for dubious value especially under the consideration that the vast majority of timer wheel timers are either canceled or rearmed before they expire. The timer pull model avoids the above by removing the target computation on enqueue and queueing timers always on the CPU on which they get armed. This is achieved by having separate wheels for CPU pinned timers and global timers which do not care about where they expire. As long as a CPU is busy it handles both the pinned and the global timers which are queued on the CPU local timer wheels. When a CPU goes idle it evaluates its own timer wheels: - If the first expiring timer is a pinned timer, then the global timers can be ignored as the CPU will wake up before they expire. - If the first expiring timer is a global timer, then the expiry time is propagated into the timer pull hierarchy and the CPU makes sure to wake up for the first pinned timer. The timer pull hierarchy organizes CPUs in groups of eight at the lowest level and at the next levels groups of eight groups up to the point where no further aggregation of groups is required, i.e. the number of levels is log8(NR_CPUS). The magic number of eight has been established by experimention, but can be adjusted if needed. In each group one busy CPU acts as the migrator. It's only one CPU to avoid lock contention on remote timer wheels. The migrator CPU checks in its own timer wheel handling whether there are other CPUs in the group which have gone idle and have global timers to expire. If there are global timers to expire, the migrator locks the remote CPU timer wheel and handles the expiry. Depending on the group level in the hierarchy this handling can require to walk the hierarchy downwards to the CPU level. Special care is taken when the last CPU goes idle. At this point the CPU is the systemwide migrator at the top of the hierarchy and it therefore cannot delegate to the hierarchy. It needs to arm its own timer device to expire either at the first expiring timer in the hierarchy or at the first CPU local timer, which ever expires first. This completely removes the overhead from the enqueue path, which is e.g. for networking a true hotpath and trades it for a slightly more complex idle path. This has been in development for a couple of years and the final series has been extensively tested by various teams from silicon vendors and ran through extensive CI. There have been slight performance improvements observed on network centric workloads and an Intel team confirmed that this allows them to power down a die completely on a mult-die socket for the first time in a mostly idle scenario. There is only one outstanding ~1.5% regression on a specific overloaded netperf test which is currently investigated, but the rest is either positive or neutral performance wise and positive on the power management side. - Fixes for the timekeeping interpolation code for cross-timestamps: cross-timestamps are used for PTP to get snapshots from hardware timers and interpolated them back to clock MONOTONIC. The changes address a few corner cases in the interpolation code which got the math and logic wrong. - Simplifcation of the clocksource watchdog retry logic to automatically adjust to handle larger systems correctly instead of having more incomprehensible command line parameters. - Treewide consolidation of the VDSO data structures. - The usual small improvements and cleanups all over the place" * tag 'timers-core-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (62 commits) timer/migration: Fix quick check reporting late expiry tick/sched: Fix build failure for CONFIG_NO_HZ_COMMON=n vdso/datapage: Quick fix - use asm/page-def.h for ARM64 timers: Assert no next dyntick timer look-up while CPU is offline tick: Assume timekeeping is correctly handed over upon last offline idle call tick: Shut down low-res tick from dying CPU tick: Split nohz and highres features from nohz_mode tick: Move individual bit features to debuggable mask accesses tick: Move got_idle_tick away from common flags tick: Assume the tick can't be stopped in NOHZ_MODE_INACTIVE mode tick: Move broadcast cancellation up to CPUHP_AP_TICK_DYING tick: Move tick cancellation up to CPUHP_AP_TICK_DYING tick: Start centralizing tick related CPU hotplug operations tick/sched: Don't clear ts::next_tick again in can_stop_idle_tick() tick/sched: Rename tick_nohz_stop_sched_tick() to tick_nohz_full_stop_tick() tick: Use IS_ENABLED() whenever possible tick/sched: Remove useless oneshot ifdeffery tick/nohz: Remove duplicate between lowres and highres handlers tick/nohz: Remove duplicate between tick_nohz_switch_to_nohz() and tick_setup_sched_timer() hrtimer: Select housekeeping CPU during migration ...

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull ntfs update from Christian Brauner: "This removes the old ntfs driver. The new ntfs3 driver is a full replacement that was merged over two years ago. We've went through various userspace and either they use ntfs3 or they use the fuse version of ntfs and thus build neither ntfs nor ntfs3. I think that's a clear sign that we should risk removing the legacy ntfs driver. Quoting from Arch Linux and Debian: - Debian does neither build the legacy ntfs nor the new ntfs3: "Not currently built with Debian's kernel packages, 'ntfs' has been symlinked to 'ntfs-3g' as it relates to fstab and mount commands. Debian kernels are built without support of the ntfs3 driver developed by Paragon Software." (cf. [2]) - Archlinux provides ntfs3 as their default since 5.15: "All officially supported kernels with versions 5.15 or newer are built with CONFIG_NTFS3_FS=m and thus support it. Before 5.15, NTFS read and write support is provided by the NTFS-3G FUSE file system." (cf. [1]). It's unmaintained apart from various odd fixes as well. Worst case we have to reintroduce it if someone really has a valid dependency on it. But it's worth trying to see whether we can remove it" Link: https://wiki.archlinux.org/title/NTFS [1] Link: https://wiki.debian.org/NTFS [2] * tag 'vfs-6.9.ntfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs: remove NTFS classic from docum. index fs: Remove NTFS classic

2024-03-07leds: Introduce ExpressWire libraryDuje Mihanović
The ExpressWire protocol is shared between at least KTD2692 and KTD2801 with slight differences such as timings and the former not having a defined set of pulses for enabling the protocol (possibly because it does not support PWM unlike KTD2801). Despite these differences the ExpressWire handling code can be shared between the two, so in preparation for adding KTD2801 support introduce a library implementing this protocol.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.9 Quite a few changes to extend support to SCMI v3.2 specification, to enhance notification handling and other miscellaneous updates. 1. Enhancements to notification handling Until now, trying to register a notifier for an unsuppported notification returned an error genrating unneeded message exchanges with the SCMI platform. This can be avoided by looking up in advance the specific protocol and resources available. With these changes SCMI driver user will fail to register a notifier if the related command or resource is not supported (like before) without the need of exchanging any message. Perf notifications are also extended to provide the pre-calculated frequencies corresponding to the level or index carried by the 2. More SCMI v3.2 related updates One of the main addition includes a centralized support to the SCMI core to handle v3.2 optional protocol version negotiation, so that at protocol initialization time, if the platform advertised version is newer than supported by the kernel and protocol version negotiation is supported, the SCMI core will attempt to negotiate an older protocol version. It also includes the clock get permissions which indicates if any of the clock operations are forbidden by the platform for the OSPM agent. It can be used in the clock driver to avoid unnecessary message exchanges between the kernel and the platform which will always end up with the failure. It also includes other missing bits of clock v3.2 protocol so that the supported protocol version can be bumped to 0x30000 (v3.2). 3. Miscellaneous updates This includes addition of warning if the domain frequency multiplier is 0 or rounded off to indicate the actual frequencies are either wrong ot rounded off, hardening of clock domain info lookups, addition of multiple protocols registration support within a SCMI driver, update to SCMI entry in MAINTAINERS to include HWMON driver and constifying the scmi_bus_type structure. This also includes couple for fixes to minor issues: double free in SMC transport cleanup path and struct kernel-doc warnings in optee transport. * tag 'scmi-updates-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (29 commits) MAINTAINERS: Update SCMI entry with HWMON driver firmware: arm_scmi: Update the supported clock protocol version firmware: arm_scmi: Add standard clock OEM definitions firmware: arm_scmi: Add clock check for extended config support firmware: arm_scmi: Add support for v3.2 NEGOTIATE_PROTOCOL_VERSION firmware: arm_scmi: Fix struct kernel-doc warnings in optee transport firmware: arm_scmi: Report frequencies in the perf notifications firmware: arm_scmi: Use opps_by_lvl to store opps firmware: arm_scmi: Implement is_notify_supported callback in powercap protocol firmware: arm_scmi: Implement is_notify_supported callback in reset protocol firmware: arm_scmi: Implement is_notify_supported callback in sensor protocol firmware: arm_scmi: Implement is_notify_supported callback in clock protocol firmware: arm_scmi: Implement is_notify_supported callback in system power protocol firmware: arm_scmi: Implement is_notify_supported callback in power protocol firmware: arm_scmi: Implement is_notify_supported callback in perf protocol firmware: arm_scmi: Add a common helper to check if a message is supported firmware: arm_scmi: Check for notification support firmware: arm_scmi: Make scmi_bus_type const firmware: arm_scmi: Fix double free in SMC transport cleanup path firmware: arm_scmi: Implement clock get permissions ...

2024-03-03docs: new text on bisecting which also covers bug validationThorsten Leemhuis
Add a second document on bisecting regressions explaining the whole process from beginning to end -- while also describing how to validate if a problem is still present in mainline. This "two in one" approach is possible, as checking whenever a bug is in mainline is one of the first steps before performing a bisection anyway and thus needs to be described. Due to this approach the text also works quite nicely in conjunction with Documentation/admin-guide/reporting-issues.rst, as it covers all typical cases where users will need to build a kernel in exactly the same order. The text targets users that normally run kernels from their Linux distributor who might never have compiled their own kernel. This aim is why the first kernel built while following this guide is generated from the latest mainline codebase. This will rule out that the regression (a) was fixed already and (b) is caused by config change a vendor distributor performed; checking mainline will furthermore (c) determine if the issue is something that needs to be reported to the regular developers or the stable team (this is needed even when readers bisect within a stable series). Only then are readers instructed to build their own variant of the 'good' kernel to validate the trimmed .config file created during early in the guide, as performing a bisection with a broken one would be a waste of time. There is a small downside of this order: readers might have to go back to testing mainline, if it turns out there is a problem with their .config. But that should be rare -- and if the regression was already fixed readers might not get to this point anyway. Hence in the end this order should mean that readers built less kernels overall. This sequence allows the text to easily cover the "check if a bug is present in the upstream kernel" case while only making things a tiny bit more complicated. The text tries to prevent readers from running into many mistakes users are known to frequently make. The steps required for this might look superfluous for people that are already familiar with bisections -- but anyone with that knowledge should be able to adapt the instructions to their use-case or will not need this text at all. Style and structure of the text match the one Documentation/admin-guide/quickly-build-trimmed-linux.rst uses. Quite a few paragraphs are even copied from there and not changed at all or only slightly. This will complicate maintenance, as some future changes to one of these documents will have to be replicated in the other. But this is the lesser evil: solutions like "sending readers from one document over to the other" or "extracting the common parts into a separate document" might work in other cases, but would be too confusing here given the topic and the target audience.

2024-02-29MAINTAINERS: Update SiFive driver maintainersSamuel Holland
Add myself as a maintainer for the various SiFive drivers, since I have been performing cleanup activity on these drivers and reviewing patches to them for a while now. Remove Palmer as a maintainer, as he is focused on overall RISC-V architecture support. Collapse some duplicate entries into the main SiFive drivers entry: - Conor is already maintainer of standalone cache drivers as a whole, and these files are also covered by the "sifive" file name regex. - Paul's git tree has not been updated since 2018, and all file names matching the "fu540" pattern also match the "sifive" pattern. - Green has not been active on the LKML for a couple of years.

2024-02-29gpio: nomadik: extract GPIO platform driver from drivers/pinctrl/nomadik/Théo Lebrun
Previously, drivers/pinctrl/nomadik/pinctrl-nomadik.c registered two platform drivers: pinctrl & GPIO. Move the GPIO aspect to the drivers/gpio/ folder, as would be expected. Both drivers are intertwined for a reason; pinctrl requires access to GPIO registers for pinmuxing, pull-disable, disabling interrupts while setting the muxing and wakeup control. Information sharing is done through a shared array containing GPIO chips and a few helper functions. That shared array is not touched from gpio-nomadik when CONFIG_PINCTRL_NOMADIK is not defined. Make no change to the code that moved into gpio-nomadik; there should be no behavior change following. A few functions are shared and header comments are added. Checkpatch warnings are addressed. NUM_BANKS is renamed to NMK_MAX_BANKS. It is supported to compile gpio-nomadik without pinctrl-nomadik. The opposite is not true.
