2011-08-04drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC Lines (here: Asus M2A-VM HDMI)Thomas Reim4-12/+80
Some integrated ATI Radeon chipset implementations with add-on HDMI card (e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even when the add-on card is not plugged in or HDMI is disabled in BIOS setup. In this case, drm_get_edid() and drm_edid_block_valid() periodically dump data and kernel errors into system log files and onto terminals. For these connectors DDC probing is extended by a check for a correct EDID header. Only in case a valid EDID header is also found, the (HDMI or DVI) connector will be used by the Radeon driver. This prevents the kernel driver from useless flooding of logs and terminal sessions with EDID dumps and error messages. This patch adds a flag 'requires_extended_probe' to the radeon_connector structure. In function radeon_connector_needs_extended_probe() this flag can be set on a chipset family/vendor/connector type specific basis. In addition, function radeon_ddc_probe() has been adapted to perform extended DDC probing if required by the connector's flag. Requires function drm_edid_header_is_valid() in DRM module provided by [PATCH] drm: Separate EDID Header Check from EDID Block Check.

Display port pipe selection on CPT is not done with a bit in the output register, rather it is controlled by a couple of bits in the separate transcoder register which indicate which display port output is connected to the transcoder. This patch replaces the simplistic macro DP_PIPE_ENABLED with the rather more complicated function dp_pipe_enabled which checks the output register to see if that is enabled, and then goes on to either check the output register pipe selection bit (on non-CPT) or the transcoder DP selection bits (on CPT).
