[Linux-fbdev-users] radeonfb FBIO_WAITFORVSYNC

[Andrew H. <a....@ca...>]

Hi,

Sorry if this is a noob boob, but are there any patches
that will add FBIO_WAITFORVSYNC functionality to ioctl
in radeon_base.c?

I'm hoping to use the framebuffer in an embedded pc and
need as much mapped video ram as possible with the
ability to pan on a vsync. Would I be better off looking
at another manufacturer? It seemed that the Radeons give
a good Mb per buck ratio.

I got myself a 9250 128Mb PCI and so far found that I
can map all the memory to user space; but only after
I've started X on the device first and then closed it
down again. Otherwise I get "Found 0k...videoram" in
dmesg?

Any advice would be greatly appreciated?

Cheers, Andy.
