MTRR settings works on other core i5 machine :) (Announce)

Hi,
I had received an email from Bruno who tested my VESATEST on his core i5 680 with following result:
640 x 480 Video mode Transfer rate 112 Bank switched 39 MB/s 4112 Linear frame buffer 35 MB/s 112 Bank switch MTRR WC set 2920 MB/s 4112 Linear frame buffer MTTR WC set 250 MB/s
It's weird that BS mode is such faster than LFB mode but performance is still good compared to my poor core i5 750 system from HP. So it seems that HP BIOS is kinda retarded and didn't fully initialized the CPU/integrated MCH.

Hmmm, you didn't specify what switches to use / were used, so I don't have the same results as you. Oh well, hopefully what I did give is enough for something. (Feel free to suggest the appropriate test for me, otherwise I'm hopeless / clueless!)

If you downloaded vesatest.zip package from my site, you can find test640.bat script that will run sequentiually 4 tests in 640x480 BS/LFB without and with MTRRs set. That was exactly that Bruno reported. In your case you ran BS without MTRR set so such poor result could be expected...

Oops, I almost forgot about (re)testing this for you! :-(

MTRR settings works on other core i5 machine :)

Thx.
I found there's a bug in calculating MTRR mask in some cases of LFB size is not exactly power of 2. Mask is then slightly out of range and this cause that performance in LFB mode is so poor. In BS mode it's used fixed range MTRR so it works. I have it on my (loong) todo list to fix it...
