A little bit of foot work and things tell me that chip has a GIC400 in it, and the GIC400 says: GIC-400 can be configured to support only the required number of cores and interrupts to reduce gate count. GIC-400 implements GICv2 architecture, Security and Virtualization Extensions, for more information see Arm Generic Interrupt Controller Architecture version 2.0. So, no, this is not a V3 gic, so no bhyve/arm is not going to work on it. > On Sat, Jun 16, 2018 at 5:32 AM Marcin Wojtas <mw@semihalf.com> wrote: > > > 2018-06-15 20:40 GMT+02:00 Alexandru Elisei <alexandru.elisei@gmail.com>: > > > > > > On Fri, Jun 15, 2018 at 8:51 PM, Jim Thompson <jim@netgate.com> wrote: > > > > > > > > > > > > https://gist.github.com/gonzopancho/760ab9ecee9dfbc1b6033e48647a4b48 > > > > > > > > Note: we haven?t upstreamed everything.
