Cover letter [RFC PATCH 0/4] ARM: add support for hw-breakpoints [v3]
Hello,
Quoted 12 lines
This is version 3 of the RFC patches originally posted at:
v1.) http://lists.infradead.org/pipermail/linux-arm-kernel/2010-February/009084.html
v2.) http://lists.infradead.org/pipermail/linux-arm-kernel/2010-March/011170.htmlChanges from v2 include:
- Based on 2.6.35-rc2
- Updated to use new hw-breakpoint API features
- Addressed some comments from Frederic on LKML
- Complete redesign of the ptrace interface so that it follows the ARM ARM (v7) register structure more closely.

Unfortunately, I've only managed to compile-test this and check that the resulting image boots. The main reasons for posting are (a) to support current GDB development and (b) to attract comments on the code.
I've managed to do some preliminary testing using the GDB work in progress and found a few coding howlers. Rather than submit a new patchset, I'll keep an up-to-date patch series, rebased against the latest mainline tag here:
http://www.linux-arm.org/git?p=linux-2.6-wd.git;a=shortlog;h=refs/heads/hw-breakpoint
Once the GDB work is complete, I'll submit v4 to this list.
Cheers,
Will
