| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that MI_FLUSH would flush the TLBs in addition to the rest of the caches indicated in the MI_FLUSH command. However starting with Ivybridge, the register defaults to 0x2800 out of reset, meaning that to invalidate the TLB we need to use PIPE_CONTROL. Since we're not doing that yet, go back to the old default so things work. v2: don't forget to actually *clear* the new bit Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Kenneth Graunke <kenneth@whitecape.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CPT pipe select is different from previous generations (using two bits instead of one). All of the paths from intel_disable_pch_ports were not making this distinction. Mode setting with pipe A turned off would then also force all outputs on pipe B to get turned off as the disable code would mistakenly decide that all of these outputs were on pipe A and turn them off.

* | drm/radeon: Allow panel preferred EDID to override BIOS native modeMatthew Garrett2011-08-121-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have two sources of information about panel capabilities on mobile radeon - the BIOS, which gives us a native mode, and the panel's preferred mode. In theory these two will always match, but there's some corner cases where the BIOS hasn't been fully initialised and so the native mode in it ends up with default values. However, if we get a panel with reasonable EDID, it's probably the case that the panel's preferred mode does actually represent the panel capabilities. This patch handles that case by replacing the native mode with the panel's preferred mode if the resolutions don't match. Systems without a valid internal panel EDID will still use the BIOS native mode.

* drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC ↵Thomas Reim2011-08-044-12/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lines (here: Asus M2A-VM HDMI) 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Failing to pin a scanout buffer will most likely lead to a black screen, so if the GPU is wedged, then just let the pin happen and hope that things work out OK.

| | * drm/i915: fix CB tuning check for ILK+Jesse Barnes2011-07-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CB tuning is needed to handle potential process variations that might cause clock jitter for certain PLL settings. However, we were setting it incorrectly since we were using the wrong M value as a check (M1 when we needed to use the whole M value). Fix it up, making my HDMI attached display a little prettier (used to have occasional dots crawl across the display).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writes to the plane control register are buffered in the chip until a write to the DSPADDR (pre-965) or DSPSURF (post-965) register occurs.
