From 9744d1a547847dea89277b00606fe4c837c1b4ea Mon Sep 17 00:00:00 2001 From: Frédéric Danis Date: Fri, 20 Mar 2020 10:59:22 +0100 Subject: cmd: Add command to display or save Linux PStore dumps This patch adds a new pstore command allowing to display or save ramoops logs (oops, panic, console, ftrace and user) generated by a previous kernel crash. PStore parameters can be set in U-Boot configuration file, or at run-time using "pstore set" command. Records size should be the same as the ones used by kernel, and should be a power of 2. This command allows: - to display uncompressed logs - to save compressed or uncompressed logs, compressed logs are saved as a compressed stream, it may need some work to be able to decompress it, e.g. adding a fake header: "printf "\x1f\x8b\x08\x00\x00\x00\x00\x00\x00\x00" | cat - dmesg-ramoops-0.enc.z | gzip -dc" - ECC part is not used to check memory corruption - only 1st FTrace log is displayed or saved Signed-off-by: Frédéric Danis [trini: Minor updates for current design, correct spacing in rST] Signed-off-by: Tom Rini Cc: Heinrich Schuchardt Cc: Wolfgang Denk Cc: Heiko Schocher --- doc/index.rst | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'doc/index.rst') diff --git a/doc/index.rst b/doc/index.rst index fd9f10f28e4..68a083b16ba 100644 --- a/doc/index.rst +++ b/doc/index.rst @@ -109,6 +109,13 @@ Android-specific features available in U-Boot. android/index +Command line +------------ +.. toctree:: + :maxdepth: 2 + + pstore.rst + Indices and tables ================== -- cgit v1.2.3
