Subject: [PATCH 2/9] OvmfPkg/CloudHv: Replace legacy 8254 PIT with local APIC timer
Date: Mon, 10 Jan 2022 15:25:53 +0100 [thread overview]
Message-ID: <bfdf5dcbc77b0a0f6f3915e4ced04b80f14fb6b6.1641824435.git.sebastien.boeuf@intel.com> (raw)
In-Reply-To: <cover.1641824435.git.sebastien.boeuf@intel.com>
From: Sebastien Boeuf <sebastien.boeuf@intel.com>
Cloud Hypervisor doesn't emulate the legacy 8254 PIT, which is why
instead of relying on it as the timer UEFI services, rely on the
XenTimerDxe implementation. This is not Xen specific, as it simply uses
the local APIC timer triggering interrupts on the vector 32.
