Subject: [PATCH v10 20/23] hw/intc/arm_gicv3: Report the NMI interrupt in gicv3_cpuif_update()
Date: Mon, 25 Mar 2024 08:48:51 +0000	[thread overview]
Message-ID: <20240325084854.3010562-21-ruanjinjie@huawei.com> (raw)
In-Reply-To: <20240325084854.3010562-1-ruanjinjie@huawei.com>

In CPU Interface, if the IRQ has the non-maskable property, report NMI to
the corresponding PE.

Signed-off-by: Jinjie Ruan <ruanjinjie@huawei.com>
Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
---
v10:
- superprio -> nmi.
- Update the commit message, superpriority -> non-maskable.
v6:
- Add Reviewed-by.
v4:
- Swap the ordering of the IFs.
v3:
- Remove handling nmi_is_irq flag.
