Actually, the matrox card has a resolution set to (if I remember, early in the morning here) 1280x1024x16, with higher modes available!! And clear text!!
Text mode or graphics mode? In graphics mode, this is not surprising (even my rather cheap card can do 1600x1200x32). But since few people use text mode today, most current cards only support pathetic text modes. And to use graphics mode for Linux VC, you need fb.
The fb console. So, yes, graphics mode. Still, that's a lot of data to map.
Well, almost 8 MB. For mmap it's not a problem. (It is a speed problem with fb console text, though, especially when scrolling. That's why I use 8 bpp for text, which is more than enough for curses/CRT anyway.)
Yes I did. But I did not see the msync() call implemented. AFAIK this is how to assure writes from memory to file.
Yes, for files. For memory devices it's not necessary AFAIK. These and read-only files are all I've mapped so far, so I hadn't added it. If you need it, I can probably add it in the next release.
Again, I'm very glad you're on to this. Do what you believe in. You have a fine group of coworkers.
So, do you need msync now or not? If so, please send me some demo/test programs.
And thanks for the exchange. I'll burden you when I have something more. (please, try iwidgets and consider their use for an IDE)
I hope you don't mean me personally. I prefer to use my text mode IDE (PENG) and don't plan to switch. ;-)
