- I posted a few times about the work I have available on ftp.
- The virtual memory patches are in the directory /pub/philip/toBruce at
- ftp.cs.vu.nl. I created this directory to send some versions to Bruce Evans,
- but everybody can use it now. Note that this version is more than 1 year old,
- it is the first version that got out, and it is based on Minix 1.6.15
-
- % How far are they gone? Where can I get them?
- %Can someone please mail me or post more details about this.
-
- The version I wrote last year implemented virtual address spaces but no paging
- to disk. When I wrote that version I had a 12M machine so there was no reason
- to assume that you could run out of memory. But at the moment I have 4M
- machine, which does run out of memory so I decided to implement paging.
- I rewrote the 386 dependent part and included paging to a disk partition
- (at_wini and floppy at the moment). This version is almost stable (I am working
- on swapoff, locking for raw disk I/O and performance improvements). After that
- I can try to create some diffs. These diffs will be incomplete, for the wrong
- assembler, and therefore for hackers only.
-
- %Normally every Minix-386 user should be interested or already using them.
-
- According to our ftp logs, many people ftp the current vm version that is
- online, but I never heard of someone who tried to get it running.
-
- %And there are also the patches for swapping(and more features) done by Michael
- %Convey, which are still in beta testing. He send me the patches as a beta
- %tester. I will try to get them running under Minix-386. Are there other
- %Minix-386 users trying the same?
-
- After both VM and paging are stable, it might be worthwhile to merge the
- machine independent parts. If you want to prepare yourself to running a paging
- vm system, it might be a good idea to get the current (non paging) version
- running.
