Subject: [PATCH v8 1/4] Revert "target/riscv: Add dummy mcountinhibit CSR for priv spec v1.11 or higher"
Date: Tue, 28 Jun 2022 15:47:34 +0530 [thread overview]
Message-ID: <20220628101737.786681-2-apatel@ventanamicro.com> (raw)
In-Reply-To: <20220628101737.786681-1-apatel@ventanamicro.com>
This reverts commit 33cc1c0b69e457f5c526f64297353cba6f7bfdb4 because
commit eab4776b2badd4088a4f807c9bb3dc453c53dc23 already implements
proper mcountinhibit CSR emulation.
