Can you explain more about the patch? I wonder what we suppose to do about [640K, 1M). In LinuxBIOS we only set [0xa0000, 0xc0000) and [0xf0000, 0xf0400) to reserved, [0xc0000, 0xf0000) and [0xf0400, 4G) as ram.. with your patch, the 1M above range will not show up on /proc/iomem YH [PATCH] Don't force reserve the 640k-1MB range >From i386 x86-64 inherited code to force reserve the 640k-1MB area. That was needed on some old systems. But we generally trust the e820 map to be correct on 64bit systems and mark all areas that are not memory correctly. This patch will allow to use the real memory in there. Or rather the only way to find out if it's still needed is to try. So far I'm optimistic. http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=dbf9272e863bf4b17ee8e3c66c26682b2061d40d _______________________________________________ fastboot mailing list [email protected] https://lists.osdl.org/mailman/listinfo/fastboot
