responded to query about save state size being hard coded.
1 comment:
Patch Set #3, Line 1056: * value of 0x400 for this value.
Where?
Patrick Rudolph noted in a previous comment: "It looks like coreboot assumes 0x400 as safe value for save state. It's hard-coded everywhere in assembly."
For starters, I found this value (0x400) at the beginning of smmrelocate.S. I will, over time, look further as the STM smm descriptor is at a defined location in the smm save state.
At the moment, the STM support code works on a Purism librem 15v4 which is a 4-core Kabylake. For other platforms and cores > 4, this is an issue that has to be worked out.
