The branch stable/13 has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=8ca5539ae1e693709553729edd7e34b90d734a85 commit 8ca5539ae1e693709553729edd7e34b90d734a85 Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2023-10-17 07:05:25 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2023-10-24 04:43:56 +0000 x86: Prefer consistent naming for loader tunables The following loader tunables do have corresponding sysctl MIBs but with inconsistent naming. That may be historical reason. Let's prefer consistent naming for them so that it will be easier to maintain. 1. hw.dmar.timeout -> hw.iommu.dmar.timeout 2. hw.lapic_eoi_suppression -> hw.apic.eoi_suppression 3. hw.lapic_tsc_deadline -> hw.apic.timer_tsc_deadline 4. hw.x2apic_enable -> hw.apic.x2apic_mode Those tunables are for field debugging, no need to keep old names for compatibility.
