Hi,
This series adds AIA irqchip_split support, effective when using AIA
with aia=aplic-imsic and -accel kvm,kernel-irqchip=split.
The main difference between what we currently have and irqchip_split()
mode is that, when using split mode, QEMU will emulate the APLIC
controller instead of using the in-kernel APLIC controller provided by
KVM.
After this series this is the matrix of which interrupt controllers
we're emulating based on 'virt' machine configuration and accelerator
properties:
Accel Accel props AIA type APLIC-m IMSIC-m APLIC-s IMSIC-s
tcg ---- aplic emul n/a emul n/a
tcg ---- aplic-imsic emul emul emul emul
kvm ---- aplic n/a n/a emul n/a
kvm none aplic-imsic n/a n/a in-kernel in-kernel
kvm irqchip=split aplic-imsic n/a n/a emul in-kernel
Patches based on alistair/riscv-to-apply.next.
Thanks!
Do you mind rebasing this again?
Thanks for the reviews!
I'm not sure which branch should I use for rebasing (it doesn't seem that your
riscv-to-apply.next or riscv-to-apply.for-upstream branches are updated), so I
rebased
it on top of 'master', fixed a couple of conflicts.
Let me know if you want a rebase based on a different branch. Thanks,
Daniel
