[PATCH 0/4] Fixes and improvements for scripts/qemugdb commands

Posted by andrey.drobyshev@virtuozzo.com 2 months, 2 weeks ago

From: Andrey Drobyshev <andrey.drobyshev@virtuozzo.com>

Commands 'qemu mtree' and 'qemu timers' are currently not working.
Luckily, fixing them requires minimal effort.

The most interesting part is adding '--detailed' option into 'qemu bt'
and 'qemu coroutine' commands.  That is based on the previous downstream
work by Vladimir.  As this approach is much heavier than the current
stack unwinding, we add it as non-default behaviour.

Andrey Drobyshev (4):
  scripts/qemugdb: mtree: Fix OverflowError in mtree with 128-bit
    addresses
  scripts/qemugdb: timers: Fix KeyError in 'qemu timers' command
  scripts/qemugdb: timers: Improve 'qemu timers' command readability
  scripts/qemugdb: coroutine: Add option for obtaining detailed trace in
    coredump
