[PATCH v3 0/8] Nvram-to-pstore

From: Aruna Balakrishnaiah
Date: Thu Apr 25 2013 - 06:18:12 EST

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 stored in a
file named [dmesg-nvram-2].

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

Aruna Balakrishnaiah (8):
powerpc/pseries: Remove syslog prefix in uncompressed oops text
powerpc/pseries: Add version and timestamp to oops header
powerpc/pseries: Introduce generic read function to read nvram-partitions
powerpc/pseries: Read/Write oops nvram partition via pstore
powerpc/pseries: Read rtas partition via pstore
powerpc/pseries: Distinguish between a os-partition and non-os partition
powerpc/pseries: Read of-config partition via pstore
powerpc/pseries: Read common partition via pstore
