Subject: [PATCH v3 04/27] KVM: arm64: Treat vCPU with pending SError as runnable
Date: Tue, 8 Jul 2025 10:25:09 -0700 [thread overview]
Message-ID: <20250708172532.1699409-5-oliver.upton@linux.dev> (raw)
In-Reply-To: <20250708172532.1699409-1-oliver.upton@linux.dev>
Per R_VRLPB, a pending SError is a WFI wakeup event regardless of
PSTATE.A, meaning that the vCPU is runnable. Sample VSE in addition to
the other IRQ lines.
