Multiple Frame buffer /dev/fb1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear Gorup,

I want to inquire about the vesafb driver, which provides only one
device node that is /dev/fb0.
I am trying to develop a qt UI for this i need to have another
framebuffer /dev/fb1, how can i add one more fb, should i use
framebuffer_alloc function to allocate a new frame buffer. Do you have
any patch for providing two frame buffers in case of vesafb driver. I
have tried on net and i failed to find any suitable patch for the
same.
