Hey all.
I was looking through prescan, I put in a little monprint for instructions
being prescanned, figuring that speeding up the prescan is probably the
easiest way for me to wring out some speed, I noted that some instructions
are prescanned up to 160 times before even finishing Uncompressing Linux.
It seems to me that caching the metadata on about three pages would be
pretty much optimal -- from the log, it looks like it tends to alternate
between two pages fairly often, and sometimes three.
I expected to find that this effected largely the BIOS, but was proven wrong
-- the most scanned parts of the BIOS are C0000:E6-FE at 24 scans.
And also, it doesn't look like a large change in methodology. I'm not
certian, however, about doing the mappings properly -- the meta cache is a
nexus structure, if I'm reading the code right.
