Hello, I find with my RS780/SB700 board (ECS A780GM-M3), the initial family 10h AP launch is not reliable. I often see a hang when when all the cores are running in parallel. The parallel execution is apparent if serial logging is enabled, because the characters logged by each core are interleaved. I noticed the AP cores do a few cf8/cfc pci config writes. Could simultaneous access to this shared index/data pair be responsible for the hang? Concerns about such conflicts is why the AMD agesa code does not run cores on the same die in parallel.
Thanks, Scott -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
