Hi,
Here is the current state of my maintainer trees.
Testing
I've updated a number of the docker containers to deal with breakages
in the crossdev environments as bullseye moves to LTS. I've dropped
the armel environment which doesn't really add much to the armhf cross
build we have that works. i686 and mipsel cross containers are bumped
up to bookworm. Currently mips64el is still broken.
gdbstub
This brings in Gustavo's patches to support MTE for system mode
expanding on the previously implemented user mode support.
plugins
I start by deprecating some options that don't make much sense for
instrumentation including 32 bit and TCI support. They will still work
but there are caveats and it doesn't seem worth wasting CI time
keeping track of them.
There are a couple of new plugins including some useful analysis ones.
The bbv plugin can generate files that can be fed into simpoint. The
cflow plugin I've posted before separately but takes advantage of the
new conditional and store helpers to try and be more efficient tracing
control flow.
Finally there is not one but two memory APIs. Pierrick's updates to
the main memory instrumentation now makes values available to the
plugins and should be used if you absolutely want to track what value
was read or stored. I've added a softmmu test case building on
memory.c and I'll merge the updated linux-user test case once its been
re-spun.
Rowan's API provides a more direct access through the existing debug
API but comes with the caveats that it should only used on memory you
don't expect to be changing. The example provided allows for the
contents of syscalls to be probed at the syscall point.
Finally there is a RFC for a gdbstub hook which I mostly wrote while I
was debugging weirdness in the memory stuff. I'll probably drop it
before the PR and let it cook a bit more on plugins/next.
The following still need review:
plugins: add ability to register a GDB triggered callback
util/timer: avoid deadlock when shutting down
tests/tcg: add a system test to check memory instrumentation
tests/tcg: only read/write 64 bit words on 64 bit systems
