Hi all, I'm working on a fam10 tree for supermicro h8dmr. I'm using CBFS.
It boots, but I'm struggling with some extreme slowness during boot. In particular, the memset function in src/lib/memset.c takes *minutes* to clear 1.2MB of ram. A little further CBFS does a memcpy which takes another 20 or 30 seconds: Stage: load fallback/coreboot_ram @ 2097152/1245184 bytes, enter @ 200000 ....LOOOOOONG pause.... Stage: after memset on-stack variables at 00ffbec8 and 00ffbed4 cbfs_decompress: algo: 0 cbfs_decompress: uncompressed ....another lengthy pause.... cbfs_decompress: memcpy from 0xffbecc to 0xffbed0 for 0x2d304 bytes done Stage: done loading. The first, lengthly pause is new; it is apparently caused by something introduced between r4368 and r4440. The second pause was there already in r4368. I understand this may have something to do with MTRRs - looking at the logs it seems MTRRs are not set up until well after CBFS has dealt with coreboot_ram. This box has 32GB of ram, in case that makes a difference. Any suggestions? Thanks, Ward. -- Ward Vandewege <w...@gnu.org> -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
