2011-12-09drm/radeon/kms: add some loop timeouts in pageflip codeAlex Deucher
commit f64964796dedca340608fb1075ab6baad5625851 upstream. Avoid infinite loops waiting for surface updates if a GPU reset happens while waiting for a page flip.

2011-12-09drm/i915: fix CB tuning check for ILK+Jesse Barnes
commit cb0e093162d7b6589c2217a00e2abfef686b32d6 upstream. 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).

commit 340764465aa4a586ca332e61ae64883e5ad6f183 upstream. Since force handling rework of d0d0a225e6ad43314c9aa7ea081f76adc5098ad4 we could end up bouncing connector status btw disconnected and unknown. When connector status change a call to output_poll_changed happen which in turn ask again for detect but with force set.

2011-11-11drm/i915/panel: Always record the backlight level again (but cleverly)Takashi Iwai
commit f52c619a590fa75276c07dfcaf380dee53e4ea4c upstream. The commit 47356eb67285014527a5ab87543ba1fae3d1e10a introduced a mechanism to record the backlight level only at disabling time, but it also introduced a regression. Since intel_lvds_enable() may be called without disabling (e.g. intel_lvds_commit() calls it unconditionally), the backlight gets back to the last recorded value. For example, this happens when you dim the backlight, close the lid and open the lid, then the backlight suddenly goes to the brightest. This patch fixes the bug by recording the backlight level always when changed via intel_panel_set_backlight(). And, intel_panel_{enable|disable}_backlight() call the internal function not to update the recorded level wrongly.

2011-10-03drm/radeon/kms: fix DDIA enable on some rs690 systemsAlex Deucher
commit fdfc61594e6de21c23f955818ef78bcab9bafe40 upstream. DVOOutputControl checks the value of of bios scratch reg 3 on some tables and assumes the encoder is already enabled if the DFP2_ACTIVE bit is set. Clear that bit so the table sets the DDIA enable bit properly.

2011-10-03drm/radeon/kms: Make GPU/CPU page size handling consistent in blit code (v2)Alex Deucher
commit 003cefe0c238e683a29d2207dba945b508cd45b7 upstream. The BO blit code inconsistenly handled the page size. This wasn't an issue on system with 4k pages since the GPU's page size is 4k as well. Switch the driver blit callbacks to take num pages in GPU page units. Fixes lemote mipsel systems using AMD rs780/rs880 chipsets. v2: incorporate suggestions from Michel.

commit 87463ff83bcda210d8f0ae440bd64d1548f852e7 upstream. Apparently this doesn't always work reliably, e.g. at resume time. Just initialize to 0, so the ring is considered empty.
