[Qemu-devel] [PATCH 0/5] Debugger enhancements

[Jan Kiszka <jan.kiszka@web.de>]

This patch series strives at improving QEMU /wrt guest debugging - for
me a very important use case of this software.

It consists of patches that refactor and enhance the
breakpoint/watchpoint support, originally driven by the need to extend
QEMU's internal API in order to enhance (real) hardware-assisted
debugging in KVM. But as the KVM maintainer refused to merge the core of
my patches until the QEMU bits went mainline, I was forced to rebase
them immediately :->. In fact, these patches now come with even more
added value also for QEMU, ie. full watchpoint support with exact PC
addresses.

Moreover, the series contains an old, unmerged patch of mine that
improves the debugability of SMP guests. For this submission, I
basically rebased and polished it further. I'm using it for months now
as it is de facto mandatory for SMP debugging.

Please review!
