Subject: [PATCH 0/8] Nvram-to-pstore
Date: Wed, 10 Apr 2013 12:50:47 +0530 [thread overview]
Message-ID: <20130410071835.20150.56489.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 stored in a
file named [dmesg-nvram-2].

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