[coreboot] Re: Extended IvyBridge CPU configuration
Hi again. There's another patch that fits to the topic that you will probably want to try out: https://review.coreboot.org/c/coreboot/+/42547/ On 12/15/19 3:57 PM, Lars Hochstetter wrote: Hi everyone, I'm looking for an option to configure my Intel IvyBridge CPU (enable / disable Hyperthreading, TurboBoost, set configurable TDP level etc.) using coreboot / nvramcui. My board is a Lenovo Thinkpad T430. So far, "only virtualization" is configurable and can not be enabled / disabled "in flight" but requires a rebuild of coreboot. Is anyone currently working on something similar? Is anything planned in that regard?

So if it doesn't end up crashing in a week or two I'd say it's stable. We'll see. On 6/20/20 1:42 PM, Lars Hochstetter wrote: Update II: All tests passed with and without HT enabled!

I don't know if it's due to coreboot or memtest86+ as memtest86+ v5.01 also took around 4+ hours for all tests with HT enabled. Maybe it is a bug with memtest86+ ?

I'll try to run all tests with and without HT on 4.12 + patchset 15 around the weekend. ___ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org ___ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org ___ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
