[Libdlo] udlfb 0.4.0

[Bernie Thompson]

This is a new release of the DisplayLink kernel framebuffer driver, udlfb.

udlfb was accepted into the Linux kernel staging tree of 2.6 a few
months ago. It needs some work to add key features and get it promoted
out of the staging tree. Roberto De Iorio, the author of udlfb and
displaylink-mod, is focusing on X server work, and is happy with this
work happening in parallel to move udlfb forward.

This first release intentionally adds no fundamentally new features.
It only gets udlfb up to sync with the displaylink-mod branch (up to
Roberto’s last 0.3 release in July 2009) that has been in use the past
few months. With this update, displaylink-mod users should be able to
switch to this version of udlfb transparently.

Bug reports are very welcome, especially regressions or problems that
would stand in the way of moving this driver forward out of staging
(comments on the post are fine for bug reports).  This is a
development release, but it should be stable for daily use.

New in 0.4.0 (since 0.2.3 currently in the Linux kernel staging tree)

   * Add dynamic modeset support (from displaylink-mod 0.3 and libdlo)
         o udlfb uses EDID to find the monitor’s preferred mode
         o udlfb no longer has fixed mode tables – it’s able to set
any mode (within the capabilities of the chip) dynamically, from the
standard VESA timing characteristics of the mode
   * Fix teardown synchronization issues (from displaylink-mod 0.3)
   * Other minor changes related to probe/modeset (from displaylink-mod 0.3)
   * Functionally identical to displaylink-mod 0.3
   * Retains basic layout of udlfb to make diffs more transparent and
understandable
