The branch main has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=12cce5994b92f8235f379d660ccb28da8e69f55b commit 12cce5994b92f8235f379d660ccb28da8e69f55b Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2023-10-17 07:05:25 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2023-10-21 01:31:58 +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.
