| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f40eb99897af665f11858dd7b56edcb62c3f3c67. There are apparently still users out there of this driver. While we'd love to remove it to ease the maintenance burden, let's reinstate it for now until better (userspace) solutions can be developed.

The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems" * tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) device property: Fix documentation for fwnode_get_next_parent() firmware_loader: fix up to_fw_sysfs() to preserve const usb.h: take advantage of container_of_const() device.h: move kobj_to_dev() to use container_of_const() container_of: add container_of_const() that preserves const-ness of the pointer driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. driver core: fix up missed scsi/cxlflash class.devnode() conversion. driver core: fix up some missing class.devnode() conversions. driver core: make struct class.devnode() take a const * driver core: make struct class.dev_uevent() take a const * cacheinfo: Remove of_node_put() for fw_token device property: Add a blank line in Kconfig of tests device property: Rename goto label to be more precise device property: Move PROPERTY_ENTRY_BOOL() a bit down device property: Get rid of __PROPERTY_ENTRY_ARRAY_EL*SIZE*() kernfs: fix all kernel-doc warnings and multiple typos driver core: pass a const * into of_device_uevent() kobject: kset_uevent_ops: make name() callback take a const * kobject: kset_uevent_ops: make filter() callback take a const * kobject: make kobject_namespace take a const * ...

For example the IP addresses in /proc/net/udp. When using emulation like qemu-user, applications are not guaranteed to be using the same byteorder as the kernel. Therefore the kernel needs to provide a way for applications to discover the byteorder used in API-filesystems. Using systemcalls is not enough because these are intercepted and translated by the emulation. Also this makes it easier for non-compiled applications like shellscripts to discover the byteorder.

Add new events such as access to illegal address (RAZWI), page fault, device unavailable. In addition, change the event workqueue to be handled in a single-threaded workqueue. - Allow the control device to work during reset of the ASIC, to enable monitoring applications to continue getting the data. - Add handling for Gaudi2 with PCI revision 2. - Reduce severity of prints due to power/thermal events. - Change how we use the h/w to perform memory scrubbing in Gaudi2. - Multiple bug fixes, refactors and renames. * tag 'misc-habanalabs-next-2022-11-23' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (63 commits) habanalabs: fix VA range calculation habanalabs: fail driver load if EEPROM errors detected habanalabs: make print of engines idle mask more readable habanalabs: clear non-released encapsulated signals habanalabs: don't put context in hl_encaps_handle_do_release_sob() habanalabs: print context refcount value if hard reset fails habanalabs: add RMWREG32_SHIFTED to set a val within a mask habanalabs: fix rc when new CPUCP opcodes are not supported habanalabs/gaudi2: added memset for the cq_size register habanalabs: added return value check for hl_fw_dynamic_send_clear_cmd() habanalabs: increase the size of busy engines mask habanalabs/gaudi2: change memory scrub mechanism habanalabs: extend process wait timeout in device fine habanalabs: check schedule_hard_reset correctly habanalabs: reset device if still in use when released habanalabs/gaudi2: return to reset upon SM SEI BRESP error habanalabs/gaudi2: don't enable entries in the MSIX_GW table habanalabs/gaudi2: remove redundant firmware version check habanalabs/gaudi: fix print for firmware-alive event habanalabs: fix print for out-of-sync and pkt-failure events ...

Now it is just used to protect device mode transitions (typically to and from buffered capture). Includes merge of an immutable i2c branch to get the new i2c_client_get_device_id() (thanks to Wolfram for providing the branch). Based on rc3 to pick up some precursor fixes from early in the cycle and avoid an unnecessarily messy history. New device support * adi,ad4310 - New driver to support this very flexible measurement device including a 24 bit ADC. Later fix for documentation build issue. * adi,adxl355 - Add support of the ADXL359 accelerometer. * adi,ltc2983 - Support additional variants of the temperatures sensor: LTC2984 with an EEPROM LTC2985, LTC2986 with only 10 channels. * invensense,icm42600 - Add support for icm42631 (needed only ID and WHOAMI) * kionix,kx022a - New driver for this 3 axis accelerometer. * maxim,max11401 - New driver to support this 24-bit 10 channel ADC. Includes some new ABI to support configuration of notch filters. * mediatek,mt6370 - Add new driver to support the ADC part of the mt6370. * st,lsm6dsx - Add support for LSM6DSV accelerometer and gyroscope. Simple additional of chip specific data and IDs. - Add support for LSM6DSV16X accelerometer and gyroscope. Compatible with features currently implemented for the LSM6DSV. * st,stm32-adc - Add support for stm32pm13x SoCs. core / subsystem wide: - Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to allow for the wrapping of attributes in the code that duplicates them for multiple buffers. - Harden against future issues with expectation that all buffer attributes are iio_dev_attrs by changing the code to take an array of pointers of the correct type. - Last transitions of drivers to local locks rather than missuses of mlock. - Add an iio_device_claim_buffer_mode() callback to avoid a race in the max30100 driver without directly using mlock. - Move mlock to the opaque IIO device structure to prevent misuse. - Add missing spi_device_id tables to support auto loading of modules. - Update some ADI maintainers in DT bindings. - A few more moves of bus drivers and core module sets to export name spaces. - Extensive use of new devm_regulator_get_enable() and friends. - Switch a bunch of i2c drivers to probe_new() including the bmp280 which makes use of the new i2c_client_get_device_id() helper to simplify this change. dt-bindings: - More use of spi-peripheral-props.yaml. Features * freescale,mpl115 - Use runtime PM to implement shutdown GPIO support. * melexis,mlx90632 - More sophisticated runtime power management - Provide access to sampling frequency. - Trivial follow up fixes. * microchip,mcp3911 - Support control of PGA. * st,lsm6dsx - Add support for software triggers for cases where the IRQ lines are not wired up. * vishay,vcnl4000 - Add control of integration time.

This implements a driver which exports access to the CBMEM entries via sysfs under /sys/bus/coreboot/devices/cbmem-<id>. This implementation is quite versatile. Examples of how it could be used are given below: * Tools like util/cbmem from the coreboot tree could use this driver instead of finding CBMEM in /dev/mem directly. Alternatively, firmware developers debugging an issue may find the sysfs interface more ergonomic than the cbmem tool and choose to use it directly. * The crossystem tool, which exposes verified boot variables, can use this driver to read the vboot work buffer. * Tools which read the BIOS SPI flash (e.g., flashrom) can find the flash layout in CBMEM directly, which is significantly faster than searching the flash directly. Write access is provided to all CBMEM regions via /sys/bus/coreboot/devices/cbmem-<id>/mem, as the existing cbmem tooling updates this memory region, and envisioned use cases with crossystem can benefit from updating memory regions.

If a port was marked with early_stop attribute, unsuccessful connection attempts will fail quickly. In addition, if an early_stop port has failed to initialize, it will ignore all future connection events until early_stop attribute is clear.

Enhancements: - introduce F2FS_IOC_START_ATOMIC_REPLACE - refactor extent_cache to add a new per-block-age-based extent cache support - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs - add proc entry to show discard_plist info - optimize iteration over sparse directories - add barrier mount option Bug fixes: - avoid victim selection from previous victim section - fix to enable compress for newly created file if extension matches - set zstd compress level correctly - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot - correct i_size change for atomic writes - allow to read node block after shutdown - allow to set compression for inlined file - fix gc mode when gc_urgent_high_remaining is 1 - should put a page when checking the summary info Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc" * tag 'f2fs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (63 commits) f2fs: reset wait_ms to default if any of the victims have been selected f2fs: fix some format WARNING in debug.c and sysfs.c f2fs: don't call f2fs_issue_discard_timeout() when discard_cmd_cnt is 0 in f2fs_put_super() f2fs: fix iostat parameter for discard f2fs: Fix spelling mistake in label: free_bio_enrty_cache -> free_bio_entry_cache f2fs: add block_age-based extent cache f2fs: allocate the extent_cache by default f2fs: refactor extent_cache to support for read and more f2fs: remove unnecessary __init_extent_tree f2fs: move internal functions into extent_cache.c f2fs: specify extent cache for read explicitly f2fs: introduce f2fs_is_readonly() for readability f2fs: remove F2FS_SET_FEATURE() and F2FS_CLEAR_FEATURE() macro f2fs: do some cleanup for f2fs module init MAINTAINERS: Add f2fs bug tracker link f2fs: remove the unused flush argument to change_curseg f2fs: open code allocate_segment_by_default f2fs: remove struct segment_allocation default_salloc_ops f2fs: introduce discard_urgent_util sysfs node f2fs: define MIN_DISCARD_GRANULARITY macro ...

Enhanced hot/cold data separation can record data block update frequency as "age" of the extent per inode, and take use of the age info to indicate better temperature type for data block allocation: - It records total data blocks allocated since mount; - When file extent has been updated, it calculate the count of data blocks allocated since last update as the age of the extent; - Before the data block allocated, it searches for the age info and chooses the suitable segment for allocation. Test and result: - Prepare: create about 30000 files * 3% for cold files (with cold file extension like .apk, from 3M to 10M) * 50% for warm files (with random file extension like .FcDxq, from 1K to 4M) * 47% for hot files (with hot file extension like .db, from 1K to 256K) - create(5%)/random update(90%)/delete(5%) the files * total write amount is about 70G * fsync will be called for .db files, and buffered write will be used for other files The storage of test device is large enough(128G) so that it will not switch to SSR mode during the test. Benefit: dirty segment count increment reduce about 14% - before: Dirty +21110 - after: Dirty +18286 Signed-off-by: qixiaoyu1 <qixiaoyu1@xiaomi.com> Signed-off-by: xiongping1 <xiongping1@xiaomi.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used. Stuff outside my tree, the dma-buf patches hit a few places, the vc4 firmware changes also do, and i915 has some interactions with MEI for discrete GPUs. I think all of those should have been acked/reviewed by relevant parties.
