Patch merged into coreboot/master: 7756fe7 x86: Minimize work done with the caches disabled in mtrr functions.
by gerrit＠coreboot.org Sept. 24, 2014

Sept. 24, 2014

the following patch was just integrated into master: commit 7756fe70eb568e1429e244306be9401357cefa43 Author: Gabe Black <gabeblack(a)google.com> Date: Tue Feb 25 01:40:34 2014 -0800 x86: Minimize work done with the caches disabled in mtrr functions. The code in src/cpu/x86/mtrr/mtrr.c disables caching in a few places when changing mtrr settings. While I can't find anything that says that's actually required, I can believe it's necessary. With that said, other code around the wrmsr instructions which actually modify the settings should be able to run with caching enabled with no ill effects. This is particularly true for two calls to printk, one in the fixed mtrr code and one in the variable, which could result in an arbitrary amount of work being done without caching. When changing the implementation of the cbmem console, these two printks caused a significant regression in boot performance on link of about 70ms which is about 10% of total firmware boot time. When the window where the cache is disabled is minimized, both this and the new implementation were about 30ms faster than the original boot time. For the variable MTRRs, we now store what we want to set the MSRs to and then write them all at once at the end of commit_var_mtrrs(). This way we don't have some set and some not, but we still minimize the time we spend with the caches disabled.

New patch to review for coreboot: 84378b1 google/panther: Be safe about invalid thermal readings
by Isaac Christensen Sept. 24, 2014

Sept. 24, 2014

Isaac Christensen (isaac.christensen(a)se-eng.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/6962 -gerrit commit 84378b19a334ae81e49e103d1721477275066da4 Author: Stefan Reinauer <reinauer(a)chromium.org> Date: Mon Mar 3 15:08:10 2014 -0800 google/panther: Be safe about invalid thermal readings In case we get an invalid thermal reading, let's run the fan at full speed rather than at low speed. This might impact the user experiance slightly in cases where the bad reading does not happen while the system is hot, but it will increase stability in the cases where the system is actually overheating. Also, set the critical temperature below tjmax, because otherwise thermal shutdown by the OS will never be triggered.
