[PATCH v5 0/5] Add RISC-V KVM AIA Support |
Date: |

This series adds support for KVM AIA in RISC-V architecture.
In order to test these patches, we require Linux with KVM AIA support which can
be found in the riscv_kvm_aia_hwaccel_v1 branch at
https://github.com/avpatel/linux.git
---
v5:
- remove the linux-header update patch since the riscv-to-apply.next QEMU has
synced up to Linux 6.5-rc1 headers.
- create the APLIC and IMSIC FDT helper functions in PATCH1
- add the irqfd support in PATCH3
- fix the comments and refine the code
v4:
- update the linux header by the scripts/update-linux-headers.sh in PATCH1
- remove the checking for "aplic_m" before creating S-mode APLIC device in
PATCH2
- add more setting when we initialize the KVM AIA chip in PATCH4
- fix msi message delivery and the APLIC devices emulation in PATCH5
- fix the AIA devices mapping with NUMA enabled in PATCH6
- add "kvm-aia" parameter to sepecify the KVM AIA mode in PATCH6
v3:
- fix typo
- tag the linux-header patch as placeholder
v2:
- rebase to riscv-to-apply.next
- update the linux header by the scripts/update-linux-headers.sh
Yong-Xuan Wang (5):
target/riscv: support the AIA device emulation with KVM enabled
target/riscv: check the in-kernel irqchip support
target/riscv: Create an KVM AIA irqchip
target/riscv: update APLIC and IMSIC to support KVM AIA
target/riscv: select KVM AIA in riscv virt machine
