Did you find this sped things up? No.. I am working for that.. Speed is good when sha256 is prepared in update_purgatory..just a sec.. while it is 2 min during verification.. one diff is that purgatory is using byte copy in memcpy while kexec had generic memcpy which has byte/word/page copy features. But, Most likely speed is low because dcache is disabled. So I am working to enable d-cache and identity mapped mmu table for crashdump regions in purgatory. ~Pratyush > > Acked-by: Geoff Levand <geoff at infradead.org> > > > _______________________________________________ > kexec mailing list > kexec at lists.infradead.org > http://lists.infradead.org/mailman/listinfo/kexec >
