This series of patches adds hardware watch register support for MIPS to the kernel. This is kind of a chicken-and-egg type of problem as you need gdb support to test it, but you cannot test gdb until the kernel support is present. These kernel patches are preliminary and undoubtedly will need some tweaking. If you want to test this out, you will need to build a suitable gdb using the patch here: http://sourceware.org/ml/gdb-patches/2008-04/msg00439.html The patches are against current linux-mips.org (commit 096bc9f852d4e782b318218d82181f4b09bac63f) My main test platform only runs 2.6.15, so I could not fully test them in the current kernel. I did test under Qemu, but since it lacks full watch register support in mips, I could not verify that it really works there. Well without further ado, here they come. David Daney
