The existing version of SMM loader uses a 64K code/data +segment and only a limited number of CPU threads can fit into one segment +(because of save state, STM, other features, etc). This loader extends beyond +the 64K segment to accomodate additional CPUs and in theory allows as many +CPU threads as possible limited only by SMRAM space and not by 64K. By default +this loader version is disabled. Please see cpu/x86/Kconfig for more info. + ### Add significant changes here |
