The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=83b003fbe965869124706b4a80b212734152356d commit 83b003fbe965869124706b4a80b212734152356d Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2023-10-04 16:28:28 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2023-10-04 16:53:17 +0000 bhyve: Build the HPET ACPI table on amd64 only There is no HPET on arm64 and vm_get_hpet_capabilities() is not implemented there. Move the vm_get_hpet_capabilities() call into build_hpet(): I cannot see a downside, and doing so eliminates a global variable and reduces the amount of code that needs to be conditionally compiled. No functional change intended.
