Subject: hw/pci-host/astro: Trigger CPU irq on CPU HPA in high memory
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=64bf09674a5911fd70a3b4050c2d7081b0353cf5;p=qemu.git

hw/pci-host/astro: Trigger CPU irq on CPU HPA in high memory

The CPU HPA is in the high F-region on PA2.0 CPUs, so use F_EXTEND()
to trigger interrupt request at the right CPU HPA address.
Note that the cpu_hpa value comes out of the IRT, which doesn't store the
higher addresss bits.
