Subject: [PATCH] intel-dri: Fix initialization if startup happens in interlaced mode [v2]
Date: Mon, 14 Nov 2011 12:21:35 +0100 [thread overview]
Message-ID: <4EC0F9BF.2060402@digadd.de> (raw)
[-- Attachment #1: Type: text/plain, Size: 463 bytes --]
My EFI BIOS starts the graphics card up in my projector's preferred EDID
mode, 1080@60i. The Intel driver does not clear the interlaced bit:
#define PIPECONF_PROGRESSIVE (0 << 21)
#define PIPECONF_INTERLACE_W_FIELD_INDICATION (6 << 21)
#define PIPECONF_INTERLACE_FIELD_0_ONLY (7 << 21)
This patch introduces a new PIPECONF_INTERLACE_MASK define and uses it
to restore progressive mode.
