Subject: [PATCH v2 7/7] KVM: riscv: selftests: add Zicfiss/Zicfilp extension to get-reg-list test
Date: Mon, 1 Jun 2026 16:43:35 +0800 [thread overview]

In-Reply-To: <20260601084336.2601675-1-inochiama@gmail.com>
The KVM RISC-V allows Zicfiss/Zicfilp extensions for Guest/VM so
add these extensions to get-reg-list test.
