I thought about something like that, but haven't added it yet.<br />First I just wanted to have something that fbcon can use, so I can easily use it for text output. And fbcon doesn't need the mmap() access, so I didn't really worry about it.<br />I see you have the Phillips compatible controller. My driver is supposed to be able to support both, selectable with a module parameter. But I only have one screen, with an Epson compatible controller, so that's the only way I was able to test it. I doubt that it works with a Phillips controlled variant right now.<br />Maybe someone can give it a try and send some feedback.Zsolthttps://www.blogger.com/profile/10882828214676373214noreply@blogger.comtag:blogger.com,1999:blog-2898895548944600630.post-21206923570655102812009-04-13T11:32:00.000-07:002009-04-13T11:32:00.000-07:00Hi Zsolt.

I have a working version of the driver which supports mmap from a user space, tested with nano-x and minigui.<BR/>http://www.at91.com/samphpbb/viewtopic.php?f=12&t=5103&sid=90a754e99893272129ac0bc08174a401Alexanderhttps://www.blogger.com/profile/10277646449761136625noreply@blogger.com
