Subject: [PATCH v3 0/8] target/loongarch: add LVZ support for TCG
Date: Fri, 10 Jul 2026 17:00:09 +0800 [thread overview]
Message-ID: <cover.1783673526.git.prcups@krgm.moe> (raw)
This patch implements Loongson VirtualiZation (LVZ) extension support
for LoongArch's TCG target. With this patch, it is now possible to start
a nested KVM-accelerated virtual machine on a TCG-emulated virtual machine.
SignKirigami (8):
target/loongarch: Define LVZ CSR fields
target/loongarch: Add LVZ CPU state definitions
target/loongarch: Add LVZ translation context flags
target/loongarch: Add LVZ guest CSR tables
target/loongarch: Dump host CSRs with LVZ state
target/loongarch: Add LVZ CPU runtime control
target/loongarch: Add LVZ MMU and PTW support
target/loongarch: Translate LVZ instructions
