yes, this started as 8i from russ. it was renamed to realemu after i made it into a fileserver providing /dev/realmode and /dev/realmodemem. this way i dont have to reimplement aux/vga's vesa code and it can be used as drop in replacement. (just start it before running aux/vga)
mkfile is fixed now. will install itself into /$objtype/bin/aux/realemu and install realemu (8) manpage. impovement on the manpage is welcome as my english is not so good :) aux/vga doesnt need to be changed for realemu. the thing that needs change is the kernel vgavesa driver to use the file /dev/realmode instead file instead of calling realmode() directly. this works with both, realemu and the original #P/realmode file. so it does not break anything. the patch: /n/sources/patch/vesa-softscreen-resize also fixes some some softscreen related mode switching bugs in devvga.c and screen.c that are unrelated to realemu. (it would crash with #P/realmode too) i forgot to submit the patch to allow writing the vga framebuffer (0xA0000-0xBFFFF) with #P/realmodemem: /n/sources/patch/realmodemem-vgamem this makes switch switch back to textmode work properly in realemu. /n/sources/patch/vesa-depth32 still, aux/vga does the channel string generation wrong for 32 bit depth modes on vesa, but this is a separate patch and has no connection to realemu. /n/sources/patch/devdraw-initscreenimage-from-isr fixes kernel panic. -- cinap
--- Begin Message ---> for everyone running realemu, please try with the new version to > see if i broke something. Why TARG=qi in the mkfile (I would have guessed 8i, but I could be wrong)? and I think the error: term% mk install cp 8.out $BIN/qi rc: null list in concatenation mk: cp 8.out $BIN/qi : exit status=rc 9367: error comes from not defining BIN? Also, there's usgae: ./8.out [-Dpt] [-s srvname] [-m mountpoint] ;-) but I'll gladly submit a man page if you throw a couple of guidelines in my direction. That said, I haven't tried it yet. I'm a little concerned about aux/vga being altered to expect the emulation in /dev/realmode* and what it may do if it's not there, which probably merely shows how limited my understanding is. I would like to see this type of change find its way into the distribution permanently, I'll certainly help if I can. ++L
