Subject: x86,kvm: Use the new workload event to trigger KVM system calls.
X-Git-Tag: develop-gem5-snapshot~544
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=92abe28af49d9194f8c5a31891ebe04b5e1dcd21;p=gem5.git

x86,kvm: Use the new workload event to trigger KVM system calls.

While events are only used for SE mode for now, this moves to using the
common mechanism and gets rid of the need for the system call specific
pseudo inst.
