[PATCH v2 0/3] char: add option to inject timestamps into logfile

Posted by Vladimir Sementsov-Ogievskiy 2 months ago

Hi all!

The ability to correlate the QEMU log and the guest log can be useful
for investigating problems. So, I suggest an option to inject timestimps
into logfile while writing it.

v2: do not make real_time_iso8601 static inline

Vladimir Sementsov-Ogievskiy (3):
  char: qemu_chr_write_log() use qemu_write_full()
  error-report: make real_time_iso8601() public
  chardev: add logtimestamp option
