The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=77404ee1e99d502345a1f9356b05c09abfbde831 commit 77404ee1e99d502345a1f9356b05c09abfbde831 Author: Andre Silva <[email protected]> AuthorDate: 2026-07-28 14:48:37 +0000 Commit: Mitchell Horne <[email protected]> CommitDate: 2026-07-28 14:53:33 +0000 x86: add AMD RAPL MSR definitions to specialreg.h specialreg.h is the tree's MSR registry and already carries the Intel RAPL group. Add the AMD RAPL package/core energy and unit MSRs here so the hwpmc RAPL class can reference them without a private driver copy. Use the names Linux's msr-index.h gives these registers.
