Hi,
I implemented the mmx fastmemcpy function from the linux kernel sources.
I haven't implemented the fastclear function yet because the kernel only
has a page clear. If I have the time I will rewrite this so it can clear
any memory range.
I have added a configure option --enable-mmx/--disable-mmx to be able to
use plex86 on non-mmx processors although I doubt anyone would want to
run it an old non-mmx processor. For some reason the diff includes all
code that shifted some lines down because of the few lines I added. I
don't know how to avoid this (should be possible).
Freedos boots with this code and I also started my win95 diskimage.
Win95 starts but I didn't wait the full boot. (takes some time you know
;-)
If you have any more of these mini projects please tell.
I tried to copy/past the diff in this mail as text but netscape mail
seems to have a problem with it and only gets the first few lines. I
don't know if attachments come through in this mailing list but the diff
is in an attachment now. If this doesn't work, any ideas?
Greetings,
Martin DvH
