Subject: [PATCH] intel-dri: Fix initialization if startup happens in interlaced mode
Date: Sun, 13 Nov 2011 22:08:41 +0100 [thread overview]
Message-ID: <4EC031D9.80204@digadd.de> (raw)
[-- Attachment #1: Type: text/plain, Size: 484 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)
Likewise, I suppose that this bit is not set for interlaced modes
either, however interlaced modes are discarded anyway.
