scripts: add ARM support to decodecode

2010-02-02T13:33:54Z

This patch adds support for decoding ARM oopses to scripts/decodecode. The following things are handled: - ARCH and CROSS_COMPILE environment variables are respected. - The Code: in x86 oopses is in bytes, while it is in either words (4 bytes) or halfwords for ARM. - Some versions of ARM objdump refuse to disassemble instructions generated by literal constants (".word 0x..."). The workaround is to strip the object file first. - The faulting instruction is marked (liked so) in ARM, but in x86. - ARM mnemonics may include characters such as [] which need to be escaped before being passed to sed for the "<- trapping instruction" substitution.

scripts: improve the decodecode script

2008-12-03T21:36:39Z

kerneloops.org has been using an improved "decodecode" script, specifically it has a special marker that shows which line in the assembly the oops happened at, like this: 20: 83 e0 03 and $0x3,%eax 23: 09 d8 or %ebx,%eax 25: 85 db test %ebx,%ebx 27: 89 02 mov %eax,(%edx) 29: 74 0f je 0x3a 2b:* 3b 73 04 cmp 0x4(%ebx),%esi <-- trapping instruction 2e: 75 05 jne 0x35 30: 89 53 04 mov %edx,0x4(%ebx) 33: eb 07 jmp 0x3c 35: 89 53 08 mov %edx,0x8(%ebx) this patch updates the kernel copy to also have this functionality.

kbuild: minor scripts/decodecode update

Remove the tmp file when exiting. Noticed by Arjan van de Ven. Catch mktemp failure and exit with message. Trap kill or other signals and exit cleanly. Signed-off-by: Randy Dunlap Signed-off-by: Sam Ravnborg

doc/oops-tracing: add Code: decode info

2007-07-16T16:05:48Z

Add info that the Code: bytes line contains or (wxyz) in some architecture oops reports and what that means. Add a script by Andi Kleen that reads the Code: line from an Oops report file and generates assembly code from the hex bytes.
