Subject: [v1][PATCH 0/6] powerpc/book3e: make kgdb to work well
Date: Thu, 20 Dec 2012 17:08:24 +0800 [thread overview]
Message-ID: <1355994510-11934-1-git-send-email-tiejun.chen@windriver.com> (raw)
v1:
* Copy thread info only when we are from !user mode since we'll get kernel stack
coming from usr directly.
* remove save/restore EX_R14/EX_R15 since DBG_EXCEPTION_PROLOG already covered
this.
* use CURRENT_THREAD_INFO() conveniently to get thread.
* fix some typos
* add a patch to make sure gdb can generate a single step properly to invoke a
kgdb state.
* add a patch to if we need to replay an interrupt, we shouldn't restore that
previous backup thread info to make sure we can replay an interrupt lately
with a proper thread info.
* rebase latest powerpc git tree
v0:
This patchset is used to support kgdb for book3e.
