# HG changeset patch # User Andrew Cooper <andrew.cooper3@citrix.com> # Date 1327758145 0 # Node ID ac9f32525376922fdf5b9efac7a1fe0ff866cc76 # Parent f8c2cf24a26cc6cdaaad9140e4b1dfc54f07bab3 vesa: flush lfb after zeroing If Xen is going to relinquish the VGA console, flush the linear frame buffer after zeroing it in vesa_endboot(). Failing to do so in some circumstances leads to the actual linear framebuffer on the graphics card still containing the output of the Xen boot console can lead to ugly graphics output when dom0 is setting up the graphics card for its own use. While the patch is quite large, it is mostly just code motion to prevent having to forward declare lfb_flush(). The only functional change to vesa_endboot() is to insert a call to lbf_flush().
