Linux Sparc V9 code optimazation
To any Sparc guru, This question relates to the effect of instruction alignment on a Sparc's Prefetch/Dispatch unit. Just how exactly does the branch prediction bits for instruction pairs in the I-Cache utilized. I'm trying to figure out the consequences of an odd word fetch into an Instruction cache line with a the fourth instruction being another branch. Please cc me as I am currently not on the mailing list.

Buddy System bitmaps
Hi, For this scenario consider a set of 4 page frames. Frames 0 and 2 are used while frames 1 and 3 are free. The question is would the bitmap for order 1 be a 1 or 0 for this scenario. I am not on the list so please cc me on your response. Thanks in advance.

Minor issue with bootsect.s. The single instance of the lds assembly instruction includes the comment of ! ds:si is source ... seg fs lds si,(bx)! ds:si is source ... Is this comment not in reverse order (i.e should be lds dest,src) Ramil J.Santamaria Toshiba America Information Systems [EMAIL PROTECTED] - 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/
