Hi, Support for boot-time loading of Intel microcode updates has landed in the kernel in r337715, and in the sysutils/devcpu-data port as of 1.20. I'd like to solicit some testing of the feature ahead of 12.0.
The port has been modified to install /boot/firmware/intel-ucode.bin. This file contains a copy of every Intel microcode update supplied by the port. Per the pkg-message, one can enable early loading of this file by specifying: cpu_microcode_load="YES" cpu_microcode_name="/boot/firmware/intel-ucode.bin" in loader.conf. The update will be applied upon a subsequent reboot. Testing consists of enabling early loading and verifying that the CPUs report an updated microcode version. If early loading fails, a message is printed to the dmesg. If your system is capable of successful ACPI suspend/resume, it is useful to also verify that the microcode remains updated following a resume. To fetch the current microcode version, use sysutils/x86info: # kldload -n cpuctl && x86info -a | grep Micro Microcode version: 0x0000000000000020 Compare with the version installed by the microcode_update rc script at run-time: # service microcode_update onestart Updating CPU Microcode... Done. # kldload -n cpuctl && x86info -a | grep Micro Microcode version: 0x0000000000000020 If your testing indicates that the boot-time loading method doesn't work, please include the dmesg in your reply. Thanks in advance. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
