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! --- Documentation/ramoops.txt | 15 +++ drivers/staging/android/Kconfig | 5 - drivers/staging/android/Makefile | 1 - drivers/staging/android/ram_console.c | 179 --------------------------------- fs/pstore/Kconfig | 7 ++ fs/pstore/inode.c | 3 + fs/pstore/platform.c | 25 +++++ fs/pstore/ram.c | 39 +++++-- fs/pstore/ram_core.c | 81 +-------------- include/linux/pstore.h | 1 + include/linux/pstore_ram.h | 19 ---- 11 files changed, 83 insertions(+), 292 deletions(-) -- Anton Vorontsov Email: cbouatmailru@gmail.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
