[Qemu-devel] [PATCH v2 2/7] stubs: VNC initialization stubs |
Date: |
Thu, 12 Nov 2015 17:02:13 -0200 |
This reduces the number of CONFIG_VNC #ifdefs in the vl.c code.
The only user-visible difference is that this will make QEMU
complain about syntax when using "-display vnc" ("VNC requires a
display argument vnc=<display>") even if CONFIG_VNC is disabled.
