2020-10-21xen-blkfront: add a parameter for disabling of persistent grantsSeongJae Park1-0/+9
Persistent grants feature provides high scalability. On some small systems, however, it could incur data copy overheads[1] and thus it is required to be disabled. It can be disabled from blkback side using a module parameter, 'feature_persistent'. But, it is impossible from blkfront side. For the reason, this commit adds a blkfront module parameter for disabling of the feature.

Patch here adds a cpumask attr to hv_gpci pmu along with ABI documentation. Primary use to expose the cpumask is for the perf tool which has the capability to parse the driver sysfs folder and understand the cpumask file. Having cpumask file will reduce the number of perf command line parameters (will avoid "-C" option in the perf tool command line).

2020-10-03power: supply: document current directionSebastian Reichel1-2/+4
Currently the sign for CURRENT_NOW and CURRENT_AVG is a bit of a mess. There are basically 3 different ways battery fuel gauges report the current: 1. uses negative values for discharging and positive values for charging 2. uses positive values for discharging and negative values for discharging (opposit of 1) 3. only uses positive values As a result userspace currently cannot use the sign at all in a generic way. Let's solve the issue by documenting a canonical way for reporting the data and ensure new drivers follow this way. Then existing drivers can be fixed on a case-by-case basis. The 'negative value = battery discharging' has been choosen, since there are only very few drivers doing it the other way around. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>

A new conversion time is returned by reading the same attribute. other positive value: Set the conversion time in milliseconds. The setting is active until a resolution change. Then it is reset to default conversion time for a new resolution. Add 'features' sysfs attribute to control optional driver settings per device. Bit masks to read/write (logical OR): 1: Enable check for conversion success. If byte 6 of scratchpad memory is 0xC after conversion, and temperature reads 85.00 (powerup value) or 127.94 (insufficient power) - return a conversion error. 2: Enable poll for conversion completion. Generate read cycles after the conversion start and wait for 1's. In parasite power mode this feature is not available. There are some clones of DS18B20 with fixed 12 bit resolution. Make the driver verify the resolution by reading back the device after resolution change.

2020-09-30mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PACXu Yilun1-0/+15
This patch implements the basic functions of the BMC chip for some Intel FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the Intel MAX 10 CPLD. This BMC chip is connected to the FPGA by a SPI bus. To provide direct register access from the FPGA, the "SPI slave to Avalon Master Bridge" (spi-avmm) IP is integrated in the chip. It converts encoded streams of bytes from the host to the internal register read/write on the Avalon bus. So This driver uses the regmap-spi-avmm for register accessing.

2020-09-28soundwire: sysfs: add slave status and device number before probePierre-Louis Bossart1-0/+18
The MIPI DisCo device properties that are read by the driver from platform firmware, or hard-coded in the driver, should only be provided as sysfs entries when a driver probes successfully. However the device status and device number is updated even when there is no driver present, and hence can be updated when a Slave device is detected on the bus without being described in platform firmware and without any driver registered/probed. As suggested by GregKH, the attribute group for Slave status and device number is is added by default upon device registration. Credits to Vinod Koul for the status_show() function, shared in a separate patch and used as is here. The status table was modified to remove an unnecessary enum and status_show() is handled in a different group attribute than what was suggested by Vinod.

ArmCP mandates that the device CPU is always an ARM processor, which might be wrong in the future. Most of this change is an internal renaming of variables, functions and defines but there are two entries in sysfs which have armcp in their names. Add identical cpucp entries but don't remove yet the armcp entries. Those will be deprecated next year. Add the documentation about it in sysfs documentation.

2020-09-13iio: temperature: mlx90632: Interface to change object ambient temperatureCrt Mori1-0/+8
Since object temperature might be different than the sensor temperature the infrared sensors should provide an interface to inject ambient temperature. This was in past done via write to ambient temperature interface (in_temp_ambient_raw), but I think most people did not know about it. This solution introduces a new iio type of the CALIBAMBIENT which is hopefully more descriptive and more explicit about the purpose and capabilities of the sensors.

2020-09-11f2fs: support age threshold based garbage collectionChao Yu1-1/+2
There are several issues in current background GC algorithm: - valid blocks is one of key factors during cost overhead calculation, so if segment has less valid block, however even its age is young or it locates hot segment, CB algorithm will still choose the segment as victim, it's not appropriate. - GCed data/node will go to existing logs, no matter in-there datas' update frequency is the same or not, it may mix hot and cold data again. - GC alloctor mainly use LFS type segment, it will cost free segment more quickly. This patch introduces a new algorithm named age threshold based garbage collection to solve above issues, there are three steps mainly: 1. select a source victim: - set an age threshold, and select candidates beased threshold: e.g. 0 means youngest, 100 means oldest, if we set age threshold to 80 then select dirty segments which has age in range of [80, 100] as candiddates; - set candidate_ratio threshold, and select candidates based the ratio, so that we can shrink candidates to those oldest segments; - select target segment with fewest valid blocks in order to migrate blocks with minimum cost; 2. select a target victim: - select candidates beased age threshold; - set candidate_radius threshold, search candidates whose age is around source victims, searching radius should less than the radius threshold. - select target segment with most valid blocks in order to avoid migrating current target segment. 3. merge valid blocks from source victim into target victim with SSR alloctor. Test steps: - create 160 dirty segments: * half of them have 128 valid blocks per segment * left of them have 384 valid blocks per segment - run background GC Benefit: GC count and block movement count both decrease obviously: - Before: - Valid: 86 - Dirty: 1 - Prefree: 11 - Free: 6001 (6001) GC calls: 162 (BG: 220) - data segments : 160 (160) - node segments : 2 (2) Try to move 41454 blocks (BG: 41454) - data blocks : 40960 (40960) - node blocks : 494 (494) IPU: 0 blocks SSR: 0 blocks in 0 segments LFS: 41364 blocks in 81 segments - After: - Valid: 87 - Dirty: 0 - Prefree: 4 - Free: 6008 (6008) GC calls: 75 (BG: 76) - data segments : 74 (74) - node segments : 1 (1) Try to move 12813 blocks (BG: 12813) - data blocks : 12544 (12544) - node blocks : 269 (269) IPU: 0 blocks SSR: 12032 blocks in 77 segments LFS: 855 blocks in 2 segments Signed-off-by: Chao Yu <yuchao0@huawei.com> [Jaegeuk Kim: fix a bug along with pinfile in-mem segment & clean up] Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

A new bus type "dfl" is introduced for private features which are not initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these private features could be handled by separate driver modules. DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on enumeration. DFL drivers could be registered on this bus to match these DFL devices. They are matched by dfl type & feature_id.

2020-09-10fsi: aspeed: Support CFAM reset GPIOJoel Stanley1-0/+8
Systems have a line for restting the remote CFAM. This is not part of the FSI master, but is associated with it, so it makes sense to include it in the master driver. This exposes a sysfs interface to reset the cfam, abstracting away the direction and polarity of the GPIO, as well as the timing of the reset pulse. Userspace will be blocked until the reset pulse is finished. The reset is hard coded to be in the range of (900, 1000) us. It was observed with a scope to regularly be just over 1ms. If the device tree property is not preset the driver will silently continue.

This adds a new feature in libnvdimm - 'Runtime Firmware Activation', and a few small cleanups and fixes in libnvdimm and DAX. I'd originally intended to make separate topic-based pull requests - one for libnvdimm, and one for DAX, but some of the DAX material fell out since it wasn't quite ready. Summary: - add 'Runtime Firmware Activation' support for NVDIMMs that advertise the relevant capability - misc libnvdimm and DAX cleanups" * tag 'libnvdimm-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm/security: ensure sysfs poll thread woke up and fetch updated attr libnvdimm/security: the 'security' attr never show 'overwrite' state libnvdimm/security: fix a typo ACPI: NFIT: Fix ARS zero-sized allocation dax: Fix incorrect argument passed to xas_set_err() ACPI: NFIT: Add runtime firmware activate support PM, libnvdimm: Add runtime firmware activation support libnvdimm: Convert to DEVICE_ATTR_ADMIN_RO() drivers/dax: Expand lock scope to cover the use of addresses fs/dax: Remove unused size parameter dax: print error message by pr_info() in __generic_fsdax_supported() driver-core: Introduce DEVICE_ATTR_ADMIN_{RO,RW} tools/testing/nvdimm: Emulate firmware activation commands tools/testing/nvdimm: Prepare nfit_ctl_test() for ND_CMD_CALL emulation tools/testing/nvdimm: Add command debug messages tools/testing/nvdimm: Cleanup dimm index passing ACPI: NFIT: Define runtime firmware activation commands ACPI: NFIT: Move bus_dsm_mask out of generic nvdimm_bus_descriptor libnvdimm: Validate command family indices

git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two small interfaces: (a) GC_URGENT_LOW mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC mode allows Android to run some lower priority GCs in background, while new ioctl discards user information without race condition when the account is removed. In addition, some patches were merged to address latency-related issues. We've fixed some compression-related bug fixes as well as edge race conditions. Enhancements: - add GC_URGENT_LOW mode in gc_urgent - introduce F2FS_IOC_SEC_TRIM_FILE ioctl - bypass racy readahead to improve read latencies - shrink node_write lock coverage to avoid long latency Bug fixes: - fix missing compression flag control, i_size, and mount option - fix deadlock between quota writes and checkpoint - remove inode eviction path in synchronous path to avoid deadlock - fix to wait GCed compressed page writeback - fix a kernel panic in f2fs_is_compressed_page - check page dirty status before writeback - wait page writeback before update in node page write flow - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry We've added some minor sanity checks and refactored trivial code blocks for better readability and debugging information" * tag 'f2fs-for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (52 commits) f2fs: prepare a waiter before entering io_schedule f2fs: update_sit_entry: Make the judgment condition of f2fs_bug_on more intuitive f2fs: replace test_and_set/clear_bit() with set/clear_bit() f2fs: make file immutable even if releasing zero compression block f2fs: compress: disable compression mount option if compression is off f2fs: compress: add sanity check during compressed cluster read f2fs: use macro instead of f2fs verity version f2fs: fix deadlock between quota writes and checkpoint f2fs: correct comment of f2fs_exist_written_data f2fs: compress: delay temp page allocation f2fs: compress: fix to update isize when overwriting compressed file f2fs: space related cleanup f2fs: fix use-after-free issue f2fs: Change the type of f2fs_flush_inline_data() to void f2fs: add F2FS_IOC_SEC_TRIM_FILE ioctl f2fs: should avoid inode eviction in synchronous path f2fs: segment.h: delete a duplicated word f2fs: compress: fix to avoid memory leak on cc->cpages f2fs: use generic names for generic ioctls f2fs: don't keep meta inode pages used for compressed block migration ...
