[kvmtool,v3,0/6] RISC-V AIA irqchip and Svnapot support

Message

Anup Patel Nov. 18, 2023, 1:28 p.m. UTC

The latest KVM in Linux-6.5 has support for:
1) Svnapot ISA extension support
2) AIA in-kernel irqchip support

This series adds corresponding changes in KVMTOOL to use the above
mentioned features for Guest/VM.

These patches can also be found in the riscv_aia_v3 branch at:
https://github.com/avpatel/kvmtool.git

Changes since v2:
 - Updated PATCH1 to sync header with released Linux-6.6
 - Addressed Drew's comments in PATCH3, PATCH4, and PATCH5

Changes since v1:
 - Rebased on commit 9cb1b46cb765972326a46bdba867d441a842af56
 - Updated PATCH1 to sync header with released Linux-6.5
