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: http://sourceware.org/ml/gdb-patches/2008-08/msg00650.html If you have any comments or questions please let me know. David Daney
