Subject: [PATCH v4 01/22] target/riscv: Fix trap cause for RV32 HS-mode CSR access from RV64 HS-mode
Date: Tue, 26 Oct 2021 12:12:06 +0530	[thread overview]
Message-ID: <20211026064227.2014502-2-anup.patel@wdc.com> (raw)
In-Reply-To: <20211026064227.2014502-1-anup.patel@wdc.com>

We should be returning illegal instruction trap when RV64 HS-mode tries
to access RV32 HS-mode CSR.

Fixes: d6f20dacea51 ("target/riscv: Fix 32-bit HS mode access permissions")
Signed-off-by: Anup Patel <anup.patel@wdc.com>
