Subject: [PATCH v8 0/11] KGDB/KDB FIQ (NMI) debugger
Date: Wed, 19 Sep 2012 16:40:06 -0700 [thread overview]
Message-ID: <20120919234003.GA24143@lizard> (raw)
Hi all,
In v8, addressed Jason's comments:
- Changed kgdb_enable_nmi() weak function to kgdb_arch callbck;
- We no longer register disable_nmi command if arch does not register
KGDB NMI handling (i.e. not filling kgdb_arch.enable_nmi callback);
- The same is for ttyNMI: if architecure does not provide us with
enable_nmi call, we don't need the tty device. Of course, there is no
way to tell wether a specific serial device can be used for NMI
debugging, as it is not serial-device specific, but specific to
whether IRQ can be rerouted to an NMI (for most our cases, pretty
much every IRQ can be rerouted, e.g. a hot-pluggable serial device on
a PCI bus).
- Rebased on the latest and greatest tty-next, just in case.
These patches can be found in the following repo (based on tty-next):
git://git.infradead.org/users/cbou/linux-nmi-kdb.git master
Old changelogs and rationale for these patches can be found here:
v1-v5, rationale: http://lkml.org/lkml/2012/9/10/2
v6: http://lkml.org/lkml/2012/9/10/2
v7: http://lkml.org/lkml/2012/9/13/367
Thanks,
