[PATCH for-6.0 5/6] hmp: Add 'info accel' command |
Date: |
Mon, 16 Nov 2020 16:10:10 +0300 |
The command is made after 'info kvm' and aims to replace it as more
generic one.
If used without parameters, the command can used to get current
accelerator. Otherwise, it may be used to determine if an accelerator is
available. Here's an example if a VM with hvf accel is started:
(qemu) info accel
hvf support: enabled
(qemu) info accel kvm
kvm support: not compiled
(qemu) info accel tcg
tcg support: disabled
