Framebuffer double buffering (via FBIOPAN_DISPLAY)
<div dir='auto'>I am not familiar with that setting, but I have really struggled to find documentation on dealing with the framebuffer. Referring to this guide, "http://betteros.org/tut/graphics1.php#doublebuffer", I attempted to set the mmap allocation size to double, but it caused the mmap to fail. I no longer believe that it is a driver issue, though, because I just tried it again on a dell laptop with Intel HD Graphics 4400 to the same failure.</div><div...

Framebuffer double buffering (via FBIOPAN_DISPLAY)
Does NOUVEAU support mmaping a double-sized Framebuffer? When attempting to run, where fd refers to "/dev/fb0": mmap(ptr, screensize * 2, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); I get back an invalid argument error. This doesn't happen if I only request a single screensize. Is this a limitation of the driver? -------------- next part -------------- An HTML attachment was
