Subject: [Patch 0/6] MIPS: Hardware watch register support for gdb (version 3).
Date: Thu, 28 Aug 2008 14:38:37 -0700 [thread overview]
Message-ID: <48B71ADD.601@avtrex.com> (raw)
Esteemed kernel hackers,
To follow is my third pass at MIPS watch register support.
This version has been tested on:
* MIPS 4KEc (mips32) with a single set of watch registers watchhi not
reporting I, R, and W conditions.
* MIPS 4KEc (mips32r2) with four sets of watch registers.
* R5000 SGI O2 (mips4 64bit) with no watch register support.
The patches are against 2.6.27-rc4
Changes from the previous version:
* Agreement from gdb maintainers that the ptrace interface is
workable.
* Work around for watchhi registers that do not report the I, R, and W
condition bits.
* General cleanup, including making much less code conditionally
compiled.
To really test the patch you will need a patched gdb. My current gdb
patch is here:

If you have any comments or questions please let me know.
