There is already one KMS abstraction layer (libkms.so) in libdrm, maybe it can serve as what we needed.<br><br>Regards,<br>Jammy<br><br><div class="gmail_quote">On Thu, Feb 17, 2011 at 9:08 AM, Clark, Rob <span dir="ltr"><<a href="mailto:rob@ti.com">rob@ti.com</a>></span> wrote:<br>

to propose a solution, but it does seem to me like there is room for<br>
some sort of kms-helper library here to handle more of the boilerplate<br>
xf86-video-* stuff.. I guess I'll have a better picture once I have a<br>
chance to add support for the various multi-monitor configurations.<br>
But certainly would be interested if anyone already has some ideas.<br>
