Subject: [PATCH RFC V2 27/37] hw/arm, gicv3: Changes to update GIC with vCPU hot-plug notification
Date: Tue, 26 Sep 2023 11:04:26 +0100 [thread overview]
Message-ID: <20230926100436.28284-28-salil.mehta@huawei.com> (raw)
In-Reply-To: <20230926100436.28284-1-salil.mehta@huawei.com>
vCPU hot-(un)plug events MUST be notified to the GIC. Introduce a notfication
mechanism to update any such events to GIC so that it can update its vCPU to GIC
CPU interface association.
This is required to implement a workaround to the limitations posed by the ARM
architecture. For details about the constraints and workarounds please check
below slides:
