ABI: pstore: Fix What field

2021-09-21T16:31:16Z

If both /sys/fs/pstore/... and /dev/pstore/... are possible, it should use, instead, two What: fields.

docs: ABI: cleanup several ABI documents

2020-10-30T12:14:29Z

There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

ABI: Fix KernelVersion tags

2019-06-15T06:12:45Z

It is "KernelVersion:" and not "Kernel Version:". Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

ABI: fix some syntax issues at the ABI database

2019-06-14T16:17:11Z

On those three files, the ABI representation described at README are violated. - at sysfs-bus-iio-proximity-as3935: a ':' character is missing after "What" - at sysfs-class-devfreq: there's a typo at Description - at sysfs-class-cxl, it is using the ":" character at a file preamble, causing it to be misinterpreted as a tag. - On the other files, instead of "What", they use "Where".

pstore: Create a convenient mount point for pstore

2013-02-12T21:07:22Z

Using /dev/pstore as a mount point for the pstore filesystem is slightly awkward. We don't normally mount filesystems in /dev/ and the /dev/pstore file isn't created automatically by anything. While this method will still work, we can create a persistent mount point in sysfs. This will put pstore on par with things like cgroups and efivarfs.

pstore: Allow the user to explicitly choose a backend

2011-07-22T23:14:39Z

pstore only allows one backend to be registered at present, but the system may provide several. Add a parameter to allow the user to choose which backend will be used rather than just relying on load order. Signed-off-by: Matthew Garrett Signed-off-by: Tony Luck

pstore: use mount option instead sysfs to tweak kmsg_bytes

2011-03-21T20:50:05Z

/sys/fs is a somewhat strange way to tweak what could more obviously be tuned with a mount option. Suggested-by: Christoph Hellwig Signed-off-by: Tony Luck Signed-off-by: Linus Torvalds

pstore: new filesystem interface to platform persistent storage

2010-12-28T22:25:21Z

Some platforms have a small amount of non-volatile storage that can be used to store information useful to diagnose the cause of a system crash. This is the generic part of a file system interface that presents information from the crash as a series of files in /dev/pstore. Once the information has been seen, the underlying storage is freed by deleting the files. Signed-off-by: Tony Luck
