34948a3 Uwe Kleine-König 07 November 2023, 09:17:59 UTC fbdev: omapfb/hdmi: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

13c8fb9 Uwe Kleine-König 07 November 2023, 09:17:43 UTC fbdev: atmel_lcdfb: Stop using platform_driver_probe() On today's platforms the benefit of platform_driver_probe() isn't that relevant any more. It allows to drop some code after booting (or module loading) for .probe() and discard the .remove() function completely if the driver is built-in. This typically saves a few 100k. The downside of platform_driver_probe() is that the driver cannot be bound and unbound at runtime which is ancient and also slightly complicates testing. There are also thoughts to deprecate platform_driver_probe() because it adds some complexity in the driver core for little gain. Also many drivers don't use it correctly.

This required some enlightenment of the PCIe AER core to workaround the fact that current generation RCH (Restricted CXL Host) platforms physically hide topology details and registers via a mechanism called RCRB (Root Complex Register Block). The next major highlight is reworks to address bugs in parsing region configurations for next generation VH (Virtual Host) topologies. The old broken algorithm is replaced with a simpler one that significantly increases the number of region configurations supported by Linux. This is again relevant for error handling so that forward and reverse address translation of memory errors can be carried out by Linux for memory regions instantiated by platform firmware. As for other cross-tree work, the ACPI table parsing code has been refactored for reuse parsing the "CDAT" structure which is an ACPI-like data structure that is reported by CXL devices. That work is in preparation for v6.8 support for CXL QoS. Think of this as dynamic generation of NUMA node topology information generated by Linux rather than platform firmware. Lastly, a number of internal object lifetime issues have been resolved along with misc. fixes and feature updates (decoders_committed sysfs ABI).

In the real world the situation ended up with multiple platform vendors inventing their own attestation report formats with the SEV-SNP implementation being a first mover to define a custom sev-guest character device and corresponding ioctl(). Later, this configfs-tsm proposal intercepted an attempt to add a tdx-guest character device and a corresponding new ioctl(). It also anticipated ARM and RISC-V showing up with more chardevs and more ioctls(). The proposal takes for granted that Linux tolerates the vendor report format differentiation until a standard arrives. From talking with folks involved, it sounds like that standardization work is unlikely to resolve anytime soon. It also takes the position that kernfs ABIs are easier to maintain than ioctl(). The result is a shared configfs mechanism to return per-vendor report-blobs with the option to later support a standard when that arrives. Part of the goal here also is to get the community into the "uncomfortable, but beneficial to the long term maintainability of the kernel" state of talking to each other about their differentiation and opportunities to collaborate. Think of this like the device-driver equivalent of the common memory-management infrastructure for confidential-computing being built up in KVM. As for establishing an "upstream path for cross-vendor confidential-computing device driver infrastructure" this is something I want to discuss at Plumbers. At present, the multiple vendor proposals for assigning devices to confidential computing VMs likely needs a new dedicated repository and maintainer team, but that is a discussion for v6.8. For now, Greg and Thomas have acked this approach and this is passing is AMD, Intel, and Google tests. Summary: - Introduce configfs-tsm as a shared ABI for confidential computing attestation reports - Convert sev-guest to additionally support configfs-tsm alongside its vendor specific ioctl() - Added signed attestation report retrieval to the tdx-guest driver forgoing a new vendor specific ioctl() - Misc cleanups and a new __free() annotation for kvfree()" * tag 'tsm-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/linux: virt: tdx-guest: Add Quote generation support using TSM_REPORTS virt: sevguest: Add TSM_REPORTS support for SNP_GET_EXT_REPORT mm/slab: Add __free() support for kvfree virt: sevguest: Prep for kernel internal get_ext_report() configfs-tsm: Introduce a shared ABI for attestation reports virt: coco: Add a coco/Makefile and coco/Kconfig virt: sevguest: Fix passing a stack buffer as a scatterlist target 05 November 2023, 01:58:13 UTC

Comes next (in number of changes) Kees' additional structures annotations to improve the sanitizers. The usual amount of cleanups apply. About the more substancial contribution, one main function of the partitions core could return an error which was not checked, this is now fixed. On the bindings side, fixed partitions can now have a compression property. Finally, an erroneous situation is now always avoided in the MAP RAM driver. CFI: - A several years old byte swap has been fixed. NAND: - The subsystem has, as usual, seen a bit of cleanup being done this cycle, typically return values of platform_get_irq() and devm_kasprintf(). There is also a better ECC check in the Arasan driver. This comes with smaller misc changes. - In the SPI-NAND world there is now support for Foresee F35SQA002G, Winbond W25N and XTX XT26 chips. SPI NOR: - For SPI NOR we cleaned the flash info entries in order to have them slimmer and self explanatory. In order to make the entries as slim as possible, we introduced sane default values so that the actual flash entries don't need to specify them. We now use a flexible macro to specify the flash ID instead of the previous INFOx() macros that had hardcoded ID lengths. Instead of: { "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0) OTP_INFO(256, 3, 0x1000, 0x1000) }, We now use: .id = SNOR_ID(0xef, 0x80, 0x20), .name = "w25q512nwm", .otp = SNOR_OTP(256, 3, 0x1000, 0x1000), - We also removed some flash entries: the very old Catalyst SPI EEPROMs that were introduced once with the SPI-NOR subsystem, and a Fujitsu MRAM. Both should use the at25 EEPROM driver. The latter even has device tree bindings for the at25 driver. - We made sure that the conversion didn't introduce any unwanted changes by comparing the .rodata segment before and after the conversion. The patches landed in linux-next immediately after v6.6-rc2, we haven't seen any regressions yet. - Apart of the autumn cleaning we introduced a new flash entry, at25ff321a, and added block protection support for mt25qu512a" * tag 'mtd/for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (91 commits) mtd: cfi_cmdset_0001: Byte swap OTP info mtd: rawnand: meson: check return value of devm_kasprintf() mtd: rawnand: intel: check return value of devm_kasprintf() mtd: rawnand: sh_flctl: Convert to module_platform_driver() mtd: spi-nor: micron-st: use SFDP table for mt25qu512a mtd: spi-nor: micron-st: enable lock/unlock for mt25qu512a mtd: rawnand: Remove unused of_gpio.h inclusion mtd: spinand: Add support for XTX XT26xxxDxxxxx mtd: spinand: winbond: add support for serial NAND flash mtd: rawnand: cadence: Annotate struct cdns_nand_chip with __counted_by mtd: rawnand: Annotate struct mtk_nfc_nand_chip with __counted_by mtd: spinand: add support for FORESEE F35SQA002G mtd: rawnand: rockchip: Use struct_size() mtd: rawnand: arasan: Include ECC syndrome along with in-band data while checking for ECC failure mtd: Use device_get_match_data() mtd: spi-nor: nxp-spifi: Convert to platform remove callback returning void mtd: spi-nor: hisi-sfc: Convert to platform remove callback returning void mtd: maps: sun_uflash: Convert to platform remove callback returning void mtd: maps: sa1100-flash: Convert to platform remove callback returning void mtd: maps: pxa2xx-flash: Convert to platform remove callback returning void ... 04 November 2023, 21:04:30 UTC

There is also a better ECC check in the Arasan driver. This comes with smaller misc changes. In the SPI-NAND world there is now support for Foresee F35SQA002G, Winbond W25N and XTX XT26 chips.

3a8ab4a Miquel Raynal 04 November 2023, 10:49:52 UTC Merge tag 'spi-nor/for-6.7' into mtd/next For SPI NOR we cleaned the flash info entries in order to have them slimmer and self explanatory. In order to make the entries as slim as possible, we introduced sane default values so that the actual flash entries don't need to specify them. We now use a flexible macro to specify the flash ID instead of the previous INFOx() macros that had hardcoded ID lengths. Instead of: - { "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0) - OTP_INFO(256, 3, 0x1000, 0x1000) }, We now use: + .id = SNOR_ID(0xef, 0x80, 0x20), + .name = "w25q512nwm", + .otp = SNOR_OTP(256, 3, 0x1000, 0x1000), We also removed some flash entries: the very old Catalyst SPI EEPROMs that were introduced once with the SPI-NOR subsystem, and a Fujitsu MRAM. Both should use the at25 EEPROM driver. The latter even has device tree bindings for the at25 driver. We made sure that the conversion didn't introduce any unwanted changes by comparing the .rodata segment before and after the conversion. The patches landed in linux-next immediately after v6.6-rc2, we haven't seen any regressions yet. Apart of the autumn cleaning we introduced a new flash entry, at25ff321a, and added block protection support for mt25qu512a.

Otherwise could hit case when order of handling them in device driver will be different. It may lead to invalid assembling fragmented packets or events order broken. Added separate workqueue with option WQ_MEM_RECLAIM for each device driver. This ensures IBI handling order and improves IBI handling performance: IBI handlers for device B are not blocked by IBI handlers for device A. Original solution (single workqueue in main driver) was able to handle also general IBI (not related to specific device) like HJ or MR. So leaving this for such purposes.

The `i3c_master_bus_init` function may attach the I2C devices before the I3C bus initialization. In this flow, the DAT `alloc_entry`` will be used before the DAT `init`. Additionally, if the `i3c_master_bus_init` fails, the DAT `cleanup` will execute before the device is detached, which will execue DAT `free_entry` function.

This can be disabled by passing BUILD_BPF_SKEL=0 to make. - Produce better error messages for bison on debug build (make DEBUG=1) by defining YYDEBUG symbol internally. perf record: - Track sideband events (like FORK/MMAP) from all CPUs even if perf record targets a subset of CPUs only (using -C option). Otherwise it may lose some information happened on a CPU out of the target list. - Fix checking raw sched_switch tracepoint argument using system BTF. This affects off-cpu profiling which attaches a BPF program to the raw tracepoint. perf lock contention: - Add --lock-cgroup option to see contention by cgroups. This should be used with BPF only (using -b option). $ sudo perf lock con -ab --lock-cgroup -- sleep 1 contended total wait max wait avg wait cgroup 835 14.06 ms 41.19 us 16.83 us /system.slice/led.service 25 122.38 us 13.77 us 4.89 us / 44 23.73 us 3.87 us 539 ns /user.slice/user-657345.slice/session-c4.scope 1 491 ns 491 ns 491 ns /system.slice/connectd.service - Add -G/--cgroup-filter option to see contention only for given cgroups. This can be useful when you identified a cgroup in the above command and want to investigate more on it.

This is to improve performance of the BPF program and to avoid nested contention on a lock in the BPF hash map. - Update callstack check for PowerPC. To find a representative caller of a lock, it needs to look up the call stacks. It ends the lookup when it sees 0 in the call stack buffer. However, PowerPC call stacks can have 0 values in the beginning so skip them when it expects valid call stacks after. perf kwork: - Support 'sched' class (for -k option) so that it can see task scheduling event (using sched_switch tracepoint) as well as irq and workqueue items. - Add perf kwork top subcommand to show more accurate cpu utilization with sched class above. It works both with a recorded data (using perf kwork record command) and BPF (using -b option).

The pipe bench is good to measure context switch overhead. With this option, it puts the reader and writer tasks in separate cgroups to enforce context switch between two different cgroups.

And you can see the pipe operation took little more. - Kill child processes when perf bench sched messaging exited abnormally. Otherwise it'd leave the child doing unnecessary work. perf test: - Fix various shellcheck issues on the tests written in shell script. - Skip tests when condition is not satisfied: - object code reading test for non-text section addresses. - CoreSight test if cs_etm// event is not available. - lock contention test if not enough CPUs. Event parsing: - Make PMU alias name loading lazy to reduce the startup time in the event parsing code for perf record, stat and others in the general case. - Lazily compute PMU default config. In the same sense, delay PMU initialization until it's really needed to reduce the startup cost. - Fix event term values that are raw events. The event specification can have several terms including event name. But sometimes it clashes with raw event encoding which starts with 'r' and has hex-digits.

31e5f93 Linus Torvalds 03 November 2023, 17:41:18 UTC Merge tag 'trace-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Remove eventfs_file descriptor This is the biggest change, and the second part of making eventfs create its files dynamically. In 6.6 the first part was added, and that maintained a one to one mapping between eventfs meta descriptors and the directories and file inodes and dentries that were dynamically created. The directories were represented by a eventfs_inode and the files were represented by a eventfs_file. In v6.7 the eventfs_file is removed. As all events have the same directory make up (sched_switch has an "enable", "id", "format", etc files), the handing of what files are underneath each leaf eventfs directory is moved back to the tracing subsystem via a callback. When an event is added to the eventfs, it registers an array of evenfs_entry's. These hold the names of the files and the callbacks to call when the file is referenced. The callback gets the name so that the same callback may be used by multiple files. The callback then supplies the filesystem_operations structure needed to create this file. This has brought the memory footprint of creating multiple eventfs instances down by 2 megs each! - User events now has persistent events that are not associated to a single processes. These are privileged events that hang around even if no process is attached to them - Clean up of seq_buf There's talk about using seq_buf more to replace strscpy() and friends. But this also requires some minor modifications of seq_buf to be able to do this - Expand instance ring buffers individually Currently if boot up creates an instance, and a trace event is enabled on that instance, the ring buffer for that instance and the top level ring buffer are expanded (1.4 MB per CPU).

The main piece is a per-console lock with several features: - Support three priorities: normal, emergency, and panic. They will be defined by a context where the lock is taken. A context with a higher priority is allowed to take over the lock from a context with a lower one. The plan is to use the emergency context for Oops and WARN() messages, and also by watchdogs. The panic() context will be used on panic CPU. - The owner might enter/exit regions where it is not safe to take over the lock. It allows the take over the lock a safe way in the middle of a message. For example, serial drivers emit characters one by one. And the serial port is in a safe state in between. Only the final console_flush_in_panic() will be allowed to take over the lock even in the unsafe state (last chance, pray, and hope). - A higher priority context might busy wait with a timeout. The current owner is informed about the waiter and releases the lock on exit from the unsafe state. - The new lock is safe even in atomic contexts, including NMI. Another change is a safe manipulation of per-console sequence number counter under the new lock. - simple_strntoull() micro-optimization - Reduce pr_flush() pooling time. - Calm down false warning about possible buffer invalid access to console buffers when CONFIG_PRINTK is disabled.

The hardware uses the same model as x86, s390 and RISC-V, where guest/host mode is orthogonal to supervisor/user mode. The virtualization extensions are very similar to MIPS, therefore the code also has some similarities but it's been cleaned up to avoid some of the historical bogosities that are found in arch/mips. The kernel emulates MMU, timer and CSR accesses, while interrupt controllers are only emulated in userspace, at least for now. RISC-V: - Support for the Smstateen and Zicond extensions - Support for virtualizing senvcfg - Support for virtualized SBI debug console (DBCN) S390: - Nested page table management can be monitored through tracepoints and statistics x86: - Fix incorrect handling of VMX posted interrupt descriptor in KVM_SET_LAPIC, which could result in a dropped timer IRQ - Avoid WARN on systems with Intel IPI virtualization - Add CONFIG_KVM_MAX_NR_VCPUS, to allow supporting up to 4096 vCPUs without forcing more common use cases to eat the extra memory overhead. - Add virtualization support for AMD SRSO mitigation (IBPB_BRTYPE and SBPB, aka Selective Branch Predictor Barrier). - Fix a bug where restoring a vCPU snapshot that was taken within 1 second of creating the original vCPU would cause KVM to try to synchronize the vCPU's TSC and thus clobber the correct TSC being set by userspace. - Compute guest wall clock using a single TSC read to avoid generating an inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads. - "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain about a "Firmware Bug" if the bit isn't set for select F/M/S combos. Likewise "virtualize" (ignore) MSR_AMD64_TW_CFG to appease Windows Server 2022. - Don't apply side effects to Hyper-V's synthetic timer on writes from userspace to fix an issue where the auto-enable behavior can trigger spurious interrupts, i.e. do auto-enabling only for guest writes. - Remove an unnecessary kick of all vCPUs when synchronizing the dirty log without PML enabled. - Advertise "support" for non-serializing FS/GS base MSR writes as appropriate. - Harden the fast page fault path to guard against encountering an invalid root when walking SPTEs. - Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n. - Use the fast path directly from the timer callback when delivering Xen timer events, instead of waiting for the next iteration of the run loop. This was not done so far because previously proposed code had races, but now care is taken to stop the hrtimer at critical points such as restarting the timer or saving the timer information for userspace. - Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future flag. - Optimize injection of PMU interrupts that are simultaneous with NMIs. - Usual handful of fixes for typos and other warts. x86 - MTRR/PAT fixes and optimizations: - Clean up code that deals with honoring guest MTRRs when the VM has non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled. - Zap EPT entries when non-coherent DMA assignment stops/start to prevent using stale entries with the wrong memtype. - Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y This was done as a workaround for virtual machine BIOSes that did not bother to clear CR0.CD (because ancient KVM/QEMU did not bother to set it, in turn), and there's zero reason to extend the quirk to also ignore guest PAT. x86 - SEV fixes: - Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while running an SEV-ES guest. - Clean up the recognition of emulation failures on SEV guests, when KVM would like to "skip" the instruction but it had already been partially emulated.

The removal sent in by Arnd Bergmann concerns the microdev board which was an early SuperH prototype board that was never used in production. With the board removed, we were able to drop the now unused code for the SH4-202 CPU and well as the driver code for the superhyway bus and a custom implementation for ioport_map() and ioport_unmap() which will allow us to simplify ioport handling in the future. Another patch set by Geert Uytterhoeven revives SuperH BIOS earlyprintk support which got accidentally disabled in e76fe57447e88916 ("sh: Remove old early serial console code V2"), the second patch in the series updates the documentation. Finally, a patch by Masami Hiramatsu fixes a regression reported by the kernel test robot which uncovered that arch/sh is not implementing arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local() instead" * tag 'sh-for-v6.7-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux: locking/atomic: sh: Use generic_cmpxchg_local for arch_cmpxchg_local() Documentation: kernel-parameters: Add earlyprintk=bios on SH sh: bios: Revive earlyprintk support sh: machvec: Remove custom ioport_{un,}map() sh: Remove superhyway bus support sh: Remove unused SH4-202 support sh: Remove stale microdev board 03 November 2023, 01:34:59 UTC

b3741ac Terry Bowman 02 November 2023, 15:52:32 UTC cxl/pci: Change CXL AER support check to use native AER Native CXL protocol errors are delivered to the OS through AER reporting. The owner of AER owns CXL Protocol error management with respect to _OSC negotiation.[1] CXL device errors are handled by a separate interrupt with native control gated by _OSC control field 'CXL Memory Error Reporting Control'. The CXL driver incorrectly checks for 'CXL Memory Error Reporting Control' before accessing AER registers and caching RCH downport AER registers. Replace the current check in these 2 cases with native AER checks.
