8e5e2c391059eaa0280a32b951e3ab1fac278364 - intel: add hfsts debug-probe driver for Intel ME/HECI firmware status

Mon, 14 Sep 2026 00:05:01 +0200

intel: add hfsts debug-probe driver for Intel ME/HECI firmware statusAdd an amd64-only, Intel-only diagnostic driver that reads ME HostFirmware Status registers from PCI configuration space without mapping the messaging BAR.Select the HFS register count per device generation, decode sparseHFS1 state, mode, and error fields, and expose raw and summarizedstatus via sysctl. Register an ISA-side hfstsfd probe for supportedRCBA/FD2 generations so firmware-hidden HECI functions can be diagnosed.Reviewed by: kbowling, adrianDifferential Revision: https://reviews.freebsd.org/D58863 List of files: /freebsd/sys/amd64/conf/NOTES

Tue, 23 Apr 2024 23:11:24 +0200

sys: add conf/std.debug, generic debugging optionsThe new sys/conf/std.debug contains the list of debugging optionsenabled by default in -CURRENT, so they don't need to be listedindividually in every kernel config.The enabled options are the set of all debug options which were enabledfor the GENERIC kernel on any platform. This means some architecturesnow have debugging options enabled in GENERIC which weren't previouslyenabled:- amd64: [1]- arm64: [2]- arm: [2]. [3]- i386: [1], [2]- powerpc: [1], [2], [3]- riscv: [2][1] ALT_BREAK_TO_DEBUGGER is now enabled.[2] BUF_TRACKING, FULL_BUF_TRACKING, and QUEUE_MACRO_DEBUG_TRASH are now enabled.[3] DEADLKRES is now enabled.While here, move the documentation for the (commented out) K*SAN optionsfor amd64 from GENERIC to NOTES.Reviewed by: impPull Request: https://github.com/freebsd/freebsd-src/pull/1124 List of files: /freebsd/sys/amd64/conf/NOTES
