Subject: [PATCH 0/6] Merge ram_console into pstore
Date: Wed, 16 May 2012 05:53:30 -0700 [thread overview]
Message-ID: <20120516125330.GA15460@lizard> (raw)
Hi all,
Currently pstore doesn't support logging kernel messages in run-time,
it only dumps dmesg when kernel oopses/panics. This makes pstore
useless for debugging hangs caused by HW issues or improper use of HW
(e.g. weird device inserted -> driver tried to write reserved bits ->
SoC hanged. In that case we don't get any messages in the pstore.
This series add a new message type for pstore, i.e. PSTORE_TYPE_CONSOLE,
plus make pstore/ram.c handle the new messages.
The old ram_console driver is removed. This might probably cause
some pain for out-of-tree code, as it would need to be adjusted...
but "no pain, no gain"? :-) Though, if there's some serious resistance,
we can probably postpone the last two patches.
These patches depend on the following series:
http://thread.gmane.org/gmane.linux.kernel/1298179
"[PATCH v2 0/6] Merge ramoops and persistent_ram, generic pstore RAM backend"
Thanks!
