( https://review.coreboot.org/c/coreboot/+/83269?usp=email ) Change subject: cpu/intel/model_206ax: Allow PL1/PL2 configuration ...................................................................... Patch Set 1: (1 comment) Patchset: PS1: Hi! This branch contains some features that I have been using in my T420 and have found them to be useful. In particular, when using the i7-3940XM CPU, which is quite powerful, it is necessary to set power and current limits in order to avoid system instability. I am sharing these patches hoping that they will be useful for other ThinkPad users. -- To view, visit https://review.coreboot.org/c/coreboot/+/83269?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: coreboot Gerrit-Branch: main Gerrit-Change-Id: I064af25ec4805fae755eea52c4c9c6d4386c0aee Gerrit-Change-Number: 83269 Gerrit-PatchSet: 1 Gerrit-Owner: Anastasios Koutian <akoutian2(a)gmail.com> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Reviewer: Patrick Rudolph <patrick.rudolph(a)9elements.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Patrick Rudolph <patrick.rudolph(a)9elements.com> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Comment-Date: Sun, 30 Jun 2024 13:28:46 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No
