This sort of testing reminds me of Linus's 100->1000 Hz change

Could we also do that with VMSPLIT?

PAGE_OFFSET was 0xC0000000 would get...")
Mmm.. bad idea. As much as I'd like the default to be 3GB_OPT, that would be a big impact to userspace, and there's no point in breaking everyone's machines when advanced users can just reconfig/recompile to get what they want.
Hm, I wonder if we could have a more fine-grained choice of the boundary? There are also systems around with e.g. 1.25G or 1.5G of main memory.Maybe something like: config VMSPLIT_1G bool "1G/3G user/kernel split" config VMSPLIT_X bool "Manual split" endchoice
... Yes, that looks like a good idea. Cheers - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
