Subject: [PATCH v4 04/33] target/riscv: Bugfix make bit 62 read-only 0 for sireg* cfg CSR read
Date: Mon, 27 Oct 2025 19:18:01 +0100 [thread overview]
Message-ID: <20251027181831.27016-5-anjo@rev.ng> (raw)
In-Reply-To: <20251027181831.27016-1-anjo@rev.ng>
According to version 20250508 of the privileged specification, a read of
cyclecfg or instretcfg through sireg* should make the MINH bit
read-only 0, currently bit 30 is zeroed.
