Patch set updated for coreboot: cpu/amd: Add CC6 support
by Timothy Pearson 10 Nov '15

Timothy Pearson (tpearson(a)raptorengineeringinc.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11979 -gerrit commit 1098f577622d28dd98895501e835b61416d3a8c5 Author: Timothy Pearson <tpearson(a)raptorengineeringinc.com> Date: Mon Jun 8 19:35:06 2015 -0500 cpu/amd: Add CC6 support This patch adds CC6 power save support to the AMD Family 15h support code. As CC6 is a complex power saving state that relies heavily on CPU, northbridge, and southbridge cooperation, this patch alters significant amounts of code throughout the tree simultaneously. Allowing the CPU to enter CC6 allows the second level of turbo boost to be reached, and also provides significant power savings when the system is idle due to the complete core shutdown.

Patch set updated for coreboot: mainboard/lenovo/t400: Increase backlight frequency to reduce flicker
by Stefan Reinauer 10 Nov '15

10 Nov '15

Stefan Reinauer (stefan.reinauer(a)coreboot.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/9331 -gerrit commit 72fa8545fef467eca98c87f25c4d8ee51bdc486c Author: Timothy Pearson <tpearson(a)raptorengineeringinc.com> Date: Mon Apr 6 22:02:18 2015 -0500 mainboard/lenovo/t400: Increase backlight frequency to reduce flicker TEST: Booted Lenovo T400 with LED backlight and verified the absence of any visible flicker along with proper operation of the brightness control.
