Subject: [PATCH] xen/x86: fix build with CONFIG_HVM=n and -Og
Date: Thu, 13 Feb 2025 13:50:54 -0500 [thread overview]
Message-ID: <20250213185055.711703-1-stewart.hildebrand@amd.com> (raw)
When building with CONFIG_HVM=n and -Og, we encounter:
prelink.o: in function `pit_set_gate':
xen/xen/arch/x86/emul-i8254.c:195: undefined reference to `destroy_periodic_time'
Add an IS_ENABLED(CONFIG_HVM) check to assist with dead code
elimination.
Fixes: 14f42af3f52d ("x86/vPIT: account for "counter stopped" time")
Signed-off-by: Stewart Hildebrand <stewart.hildebrand@amd.com>
