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 scrubbed...
