[Qemu-devel] [PATCH v2 0/8] Add LOG_GUEST_ERROR for reporting guest bugs

[Peter Maydell <peter.maydell@linaro.org>]

This patch series introduces a new logging category to
qemu_log_mask(), for reporting situations which the device
model can cope with but which indicate bugs in the guest.
The most common cause of these is "guest tried to access
a register which doesn't exist". At the moment device models
use an inconsistent mix of "silently ignore", "hw_error(),
killing qemu" and "direct print to stderr" for reporting
this kind of event.

Patches 3-8 are a random selection of ARM devices which I've
switched to using the new LOG_GUEST_ERROR (or the existing
LOG_UNIMP where that is more appropriate). There are obviously
more conversions that could be made; this is just a sample
to demonstrate the utility of the log category.

Changes v1->v2:
 * add patch 2 including qemu-log.h in hw/hw.h
 * update 3..8 to not include qemu-log.h directly
