Re: Another plex86 technical thing

[Ramon van Handel]

This morning (yes, in bed ;)) I was thinking about the two options for
caching SBE-pages, and I got rather confused.  For each code page, we have
an "original" and a "scanned" code page.. (in addition to another page
which has SBE info in it).  It's the "scanned" page that is mapped at the
corresponding physical
address, right ?

Let us pretend that we map pages r/w, and check for the dirty bit.  If I'm
not confused, then the page needs to be rescanned if it turns out the
"scanned" page is dirty.  However, how are we ever going to figure out WHAT
the modifications are to the code page ?  After all, the modifications were
written to the "scanned" page, and we're rescanning from the "original"
code page !!

I have a feeling I'm confusing things terribly, will anybody help me out ?
