Subject: [PATCH 0/4] MIPS: support return from exception; allow user to pass incorrect address to md command
Date: Tue, 10 Nov 2015 10:27:12 +0300 [thread overview]
Message-ID: <1447140436-29099-1-git-send-email-antonynpavlov@gmail.com> (raw)
This patchseries adds return from exception for MIPS, so the 'md' command
incorrect memory accesses can be handled correctly instead of crashing the system,
e.g.
barebox:/ md -l 0xa0000003+4
a0000003: xxxxxxxx ....
Without this patchseries we will get this
barebox:/ md -l 0xa0000003+4
a0000003:
Ooops, address error on load or ifetch!
...
### ERROR ### Please RESET the board ###
The patchseries is tested on QEMU Malta and Black Swift boards.
Antony Pavlov (4):
MIPS: traps.c: separate registers print stuff to show_regs()
MIPS: avoid excessive exception
MIPS: import exception registers restoring macros from linux kernel
MIPS: allow user to pass incorrect address to md command
