* powerpc/powernv Platform dump interfaceStewart Smith2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables support for userspace to fetch and initiate FSP and Platform dumps from the service processor (via firmware) through sysfs. Based on original patch from Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Flow: - We register for OPAL notification events. - OPAL sends new dump available notification. - We make information on dump available via sysfs - Userspace requests dump contents - We retrieve the dump via OPAL interface - User copies the dump data - userspace sends ack for dump - We send ACK to OPAL. sysfs files: - We add the /sys/firmware/opal/dump directory - echoing 1 (well, anything, but in future we may support different dump types) to /sys/firmware/opal/dump/initiate_dump will initiate a dump. - Each dump that we've been notified of gets a directory in /sys/firmware/opal/dump/ with a name of the dump type and ID (in hex, as this is what's used elsewhere to identify the dump). - Each dump has files: id, type, dump and acknowledge dump is binary and is the dump itself. echoing 'ack' to acknowledge (currently any string will do) will acknowledge the dump and it will soon after disappear from sysfs. OPAL APIs: - opal_dump_init() - opal_dump_info() - opal_dump_read() - opal_dump_ack() - opal_dump_resend_notification() Currently we are only ever notified for one dump at a time (until the user explicitly acks the current dump, then we get a notification of the next dump), but this kernel code should "just work" when OPAL starts notifying us of all the dumps present.

* powerpc/powernv: Read OPAL error log and export it through sysfsStewart Smith2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> This patch adds support to read error logs from OPAL and export them to userspace through a sysfs interface. We export each log entry as a directory in /sys/firmware/opal/elog/ Currently, OPAL will buffer up to 128 error log records, we don't need to have any knowledge of this limit on the Linux side as that is actually largely transparent to us. Each error log entry has the following files: id, type, acknowledge, raw. Currently we just export the raw binary error log in the 'raw' attribute. In a future patch, we may parse more of the error log to make it a bit easier for userspace (e.g. to be able to display a brief summary in petitboot without having to have a full parser). If we have >128 logs from OPAL, we'll only be notified of 128 until userspace starts acknowledging them. This limitation may be lifted in the future and with this patch, that should "just work" from the linux side. A userspace daemon should: - wait for error log entries using normal mechanisms (we announce creation) - read error log entry - save error log entry safely to disk - acknowledge the error log entry - rinse, repeat. On the Linux side, we read the error log when we're notified of it. This possibly isn't ideal as it would be better to only read them on-demand. However, this doesn't really work with current OPAL interface, so we read the error log immediately when notified at the moment. I've tested this pretty extensively and am rather confident that the linux side of things works rather well. There is currently an issue with the service processor side of things for >128 error logs though.

This includes: - Support for implementing fast_io_fail_tmo, the time that should elapse after having detected a transport layer problem and before failing I/O. - Support for implementing dev_loss_tmo, the time that should elapse after having detected a transport layer problem and before removing a remote port.

|/ | | | | | | | | | | | | | | | | | | | | | This patch simply adds a newline character at end-of-file to those files in Documentation/ that currently lack one. This is done for a few different reasons: A) It's rather annoying when you do "cat some_file.txt" that your prompt/cursor ends up at the end of the last line of output rather than on a new line. B) Some tools that process files line-by-line may get confused by the lack of a newline on the last line. C) The "\ No newline at end of file" line in diffs annoys me for some reason.

| * rename new rfkill sysfs knobsflorian@mickler.org2010-03-19
| | | | | | | | | | | | | | | | | | | | | | This patch renames the (never officially released) sysfs-knobs "blocked_hw" and "blocked_sw" to "hard" and "soft", as the hardware vs software conotation is misleading. It also gets rid of not needed locks around u32-read-access. Signed-off-by: Florian Mickler <florian@mickler.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | This moves sysfs ABI info from Documentation/rfkill.txt to the ABI subfolder and reformats it. This also schedules the deprecated sysfs parts to be removed in 2012 (claim file) and 2014 (state file). Signed-off-by: Florian Mickler <florian@mickler.org> Signed-off-by: John W.

|/ | | | | | | | | | | | Add a bare description of what /sys/devices/system/node/nodeX is. Others will follow in time but right now, none of that tree is documented. The existence of this file might at least encourage people to document new entries.
