[Qemu-devel] [PATCH v2 1/4] ui: add qapi parser for -display |
Date: |
Mon, 7 May 2018 11:55:36 +0200 |
Add parse_display_qapi() function which parses the -display command line
using a qapi visitor for DisplayOptions. Wire up as default catch in
parse_display().
Improves the error message for unknown display types.
Also enables json as -display argument, i.e. -display "{ 'type': 'gtk' }"
