Subject: [PATCH v4 0/8] Nvram-to-pstore
Date: Thu, 06 Jun 2013 00:20:39 +0530 [thread overview]
Message-ID: <20130605184756.25794.43872.stgit@aruna-ThinkPad-T420> (raw)
Currently the kernel provides the contents of p-series NVRAM only as a
simple stream of bytes via /dev/nvram, which must be interpreted in user
space by the nvram command in the powerpc-utils package. This patch set
exploits the pstore subsystem to expose each partition in NVRAM as a
separate file in /dev/pstore. For instance, Oops messages will be stored
in a file named [dmesg-nvram-2].
Changes from v3:
- Change filename prefix for of-config and common partition
Changes from v2:
- Fix renaming of pstore type ids in nvram.c
Changes from v1:
- Reduce #ifdefs by and remove forward declarations of pstore callbacks
- Handle return value of nvram_write_os_partition
- Remove empty pstore callbacks and register pstore only when pstore
is configured
