Subject: [PULL 18/23] target/riscv: Fix hstatus.GVA bit setting for traps taken from HS-mode
Date: Wed, 25 May 2022 08:44:23 +1000 [thread overview]
Message-ID: <20220524224428.552334-19-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20220524224428.552334-1-alistair.francis@opensource.wdc.com>
From: Anup Patel <apatel@ventanamicro.com>
Currently, QEMU does not set hstatus.GVA bit for traps taken from
HS-mode into HS-mode which breaks the Xvisor nested MMU test suite
on QEMU. This was working previously.
This patch updates riscv_cpu_do_interrupt() to fix the above issue.
Fixes: 86d0c457396b ("target/riscv: Fixup setting GVA")
