 |
|
Hi there,
I have followed https://wiki.gentoo.org/wiki/Intel_microcode#New_method_without_initram-fs.2Fdisk section 5 i.e. built-in to the kernel option and I have following setup
| Code: | CONFIG_MICROCODE=y
CONFIG_MICROCODE_INTEL=y
CONFIG_EXTRA_FIRMWARE="amdgpu/topaz_ce.bin amdgpu/topaz_mc.bin amdgpu/topaz_me.bin amdgpu/topaz_mec2.bin amdgpu/topaz_mec.bin amdgpu/topaz_pfp.bin amdgpu/topaz_rlc.bin amdgpu/topaz_sdma1.bin amdgpu/topaz_sdma.bin amdgpu/topaz_smc.bin intel-ucode/06-3d-04"
|
However update doesn't seem to work due to
dmesg | grep microcode
| Code: | [ 0.000000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x25 (or later)
[ 0.808193] microcode: sig=0x306d4, pf=0x40, revision=0x16
[ 0.809562] microcode: Microcode Update Driver: v2.2.
|
Any idea or what more info I should give to solve the problem?
cheers

If the firmware's built in and loading correctly, it should be one of the very first lines in dmesg - look up there. There's a chance it may have scrolled off the top of the buffer by the time you ran grep.
Also the early microcode method won't work on a 32-bit kernel for some reason. I guess Intel doesn't care about old CPUs. |

Thanks for info, indeed I have 32-bit kernel so then I guess I would need to look into some other method.

This should be fixed with a BIOS/Firmware Update for your Motherboard. |

I also can't make my firmware do the early load. Intel suggests
| Code: | | echo 1 > /sys/devices/system/cpu/microcode/reload |
This does work for me.
I have no idea if it is advisable or not |

Yep, I did upgrade BIOS and indeed the message is gone ... however since microcode in BIOS is now identical with the one in sys-firmware/intel-microcode I'm not sure whether it does something or not (cannot is in dmesg it was updated, but maybe it doesn't overwrite when it's not higher version), lets see when more recent is out.
I will try reload parameter as well and keep this thread updated.

| If the BIOS-provided version is now the same number, there's no need to have the kernel do anything. In fact you can go ahead and remove the microcode driver and intel-microcode, you'll only need to add it back if a newer one comes out and there isn't a BIOS update for it. |
