[PATCH v2 0/4] QEMU RISC-V ACLINT Support


From: Anup Patel
Subject: [PATCH v2 0/4] QEMU RISC-V ACLINT Support
Date: Sat, 24 Jul 2021 17:54:03 +0530

The RISC-V Advanced Core Local Interruptor (ACLINT) is an improvement
over the SiFive CLINT but also maintains backward compatibility with
the SiFive CLINT.

Latest RISC-V ACLINT specification (will be frozen soon) can be found at:
https://github.com/riscv/riscv-aclint/blob/main/riscv-aclint.adoc

This series:
1) Replaces SiFive CLINT implementation with RISC-V ACLINT
2) Refactors RISC-V virt machine FDT generation
3) Adds optional full ACLINT support in QEMU RISC-V virt machine

This series can be found in the riscv_aclint_v2 branch at:
https://github.com/avpatel/qemu.git

Changes since v1:
 - Split PATCH1 into two patches where one patch renames CLINT sources
   and another patch updates the implementation
 - Addressed comments from Alistar and Bin

Anup Patel (4):
  hw/intc: Rename sifive_clint sources to riscv_aclint sources
  hw/intc: Upgrade the SiFive CLINT implementation to RISC-V ACLINT
  hw/riscv: virt: Re-factor FDT generation
  hw/riscv: virt: Add optional ACLINT support to virt machine
