From 20456d6a3d18970988eedc1ab84ccde13d1ce900 Mon Sep 17 00:00:00 2001 From: Thomas Hellström Date: Wed, 15 Dec 2004 21:59:25 +0000 Subject: Unichrome DRI: Updated the driver to the new VIA security mechanisms in DRM. All command submissions now passes through DRM ioctls. If the DRM AGP ring-buffer is not enabled, it will use a DRM mechanism for submitting commands to the hardware via a PCI bus mechanism. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removed all direct write accesses to the hardware. Among other things the VQ was previously turned off for the PCI path, apparently for Tuxracer. That seemed unneeded and was removed. No visible impact on Tuxracer. Abstracted all buffer blit operations in via_ioctl.c. The blitter context is now reprogrammed before each blitting operation. Updated driver date and drm version requirement.
