Patch set updated for coreboot: 39f5ba3 Add support to run SMM handler in TSEG instead of ASEG
by Stefan Reinauer 03 Apr '12

03 Apr '12

Stefan Reinauer (stefan.reinauer(a)coreboot.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/842 -gerrit commit 39f5ba3d54bfdceb71f499318224c2aa8276ae43 Author: Stefan Reinauer <reinauer(a)chromium.org> Date: Mon Apr 2 13:24:04 2012 -0700 Add support to run SMM handler in TSEG instead of ASEG Traditionally coreboot's SMM handler runs in ASEG (0xa0000), "behind" the graphics memory. This approach has two issues: - It limits the possible size of the SMM handler (and the number of CPUs supported in a system) - It's not considered a supported path anymore in newer CPUs.
