iio: improve IIO_CONCENTRATION channel type description

2020-08-19T06:26:25+00:00

[ Upstream commit df16c33a4028159d1ba8a7061c9fa950b58d1a61 ] IIO_CONCENTRATION together with INFO_RAW specifier is used for reporting raw concentrations of pollutants. Raw value should be meaningless before being properly scaled. Because of that description shouldn't mention raw value unit whatsoever. Fix this by rephrasing existing description so it follows conventions used throughout IIO ABI docs.

fsi: aspeed: Support CFAM reset GPIO

2020-08-06T00:30:07+00:00

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 present the driver will silently continue. Reviewed-by: Andrew Jeffery Signed-off-by: Joel Stanley

habanalabs: set clock gating per engine

2020-07-10T16:53:03+00:00

For debugging purposes, we need to allow the root user better control of the clock gating feature of the DMA and compute engines. Therefore, change the clock gating debugfs interface to be bitmask instead of true/false. Each bit represents a different engine, according to gaudi_engine_id enum. See debugfs documentation for more details. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

Revert "kernel/printk: add kmsg SEEK_CUR handling"

2020-06-22T03:47:20+00:00

This reverts commit 8ece3b3eb576a78d2e67ad4c3a80a39fa6708809. This commit broke userspace. Bash uses ESPIPE to determine whether or not the file should be read using "unbuffered I/O", which means reading 1 byte at a time instead of 128 bytes at a time. I used to use bash to read through kmsg in a really quite nasty way: while read -t 0.1 -r line 2>/dev/null || [[ $? -ne 142 ]]; do echo "SARU $line" done < /dev/kmsg This will show all lines that can fit into the 128 byte buffer, and skip lines that don't. That's pretty awful, but at least it worked. With this change, bash now tries to do 1-byte reads, which means it skips all the lines, which is worse than before. Now, I don't really care very much about this, and I'm already look for a workaround. But I did just spend an hour trying to figure out why my scripts were broken. Either way, it makes no difference to me personally whether this is reverted, but it might be something to consider. If you declare that "trying to read /dev/kmsg with bash is terminally stupid anyway," I might be inclined to agree with you. But do note that bash uses lseek(fd, 0, SEEK_CUR)==>ESPIPE to determine whether or not it's reading from a pipe.

powerpc/papr_scm: Fetch nvdimm health information from PHYP

2020-06-16T01:22:43+00:00

Implement support for fetching nvdimm health information via H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair of 64-bit bitmap, bitwise-and of which is then stored in 'struct papr_scm_priv' and subsequently partially exposed to user-space via newly introduced dimm specific attribute 'papr/flags'. Since the hcall is costly, the health information is cached and only re-queried, 60s after the previous successful hcall. The patch also adds a documentation text describing flags reported by the the new sysfs attribute 'papr/flags' is also introduced at Documentation/ABI/testing/sysfs-bus-papr-pmem.
