It's a copy of ironlake_set_pipeconf with 2 differences: - There is no BPC field to set. - The interlaced mask is now 2 bits instead of 3. Signed-off-by:

On ironlake_crtc_mode_set, WARN if not using IBX or CPT. On haswell_crtc_mode_set, only run IBX/CPT code on IBX/CPT. I am still not sure whether IBX/CPT will be possible with a Haswell CPU, so leave the code there for now and put a WARN in case we spot it. Signed-off-by:

Previously we were enabling it at mode_set but never disabling. Let's follow the mode set sequence. Signed-off-by:

And the right time is exactly after/before changing PIPE_CONF. See the documentation about the mode set sequence. This code is not inside any encoder-specific callback because DDI_FUNC_CTL is part of the pipe, so it is used by all encoders. Signed-off-by:

Right now, we're trying to enable LCPLL at every mode set, but we're never disabling it. Also, we really don't want to be disabling LCPLL since it requires a very complex disable/enable sequence. This register should really be set by the BIOS and we shouldn't be touching it. Still, let's try to check its value and print some errors in case we find something wrong. We're also adding intel_ddi_get_cdclk_freq which will be used later in other places. Signed-off-by:

By using round_jiffies() we can align the wakeup of our worker to the nearest second in order to batch wakeups and reduce system load, which is useful for unimportant coarse tasks like our retire_requests. v2: round_jiffies_relative() already returns the relative timeout value, so no need to incorrectly perform the subtraction twice. The timer interface still leaves the possibility for the value of jiffies to change be we program the timer. Suggested-by:

There's is another register (a read only, so no harm done) at 0x42020 on Haswell GPUs. Let's just remove the write from the copy&paste that introduced haswell_init_clock_gating(). A note for the interested reader, it does seem we have a duplication of the 0x42020 register definition, hence the removal of 2 writes. That duplication could be the object of a later patch.

Version 2: call intel_set_pipe_timings from both i9xx_crtc_mode_set and ironlake_crtc_mode_set, instead of just ironlake, as requested by Daniel Vetter. The problem caused by calling this function from i9xx_crtc_mode_set too is that now on i9xx we write to PIPESRC before writing to DSPSIZE and DSPPOS. I could not find any evidence in our documentation that this won't work, and the docs actually say the pipe registers should be set before the plane registers. Version 3: don't remove pipeconf bits on i9xx_crtc_mode_set. Signed-off-by:

Eventhough Valleyview display block is derived from Cantiga, VLV supports eDP. So, added eDP checks in i9xx_crtc_mode_set path. v2: use different DPIO_DIVISOR values for VGA, DP and eDP v3: fix DPIO value calculation to use same values for all display interfaces v4: removed unconditional enabling of 6bpc dithering based on comments from Daniel & Jani Nikula. Also changed the display enabling order to force eDP detection first. Signed-off-by:

In valleyview voltageswing, pre-emphasis and lane control registers can be programmed only through the h/w side band fabric. Cleaned up DPLL calculations for Valleyview to support multi display configurations. v2: Based on Daniel's feedbacak, moved crt hotplug detect work around as separate patch. Also moved i9xx_update_pll_dividers to i8xx_update_pll and i9xx_update_pll. Signed-off-by:

If there's no downstream device, DPCD success is good enough. If there's a hotplug-capable downstream device, count the number of connected sinks in DP_SINK_STATUS and return success if it's non-zero. Otherwise, probe DDC and report appropriately. v2: Check DP_SINK_STATUS instead of something unrelated to sink status. Tested-by:

The set_m_n code was spread all over the mode_set function. Version 2: Don't set the DP M/N registers on ironlake_set_m_n. Daniel Vetter has plans to add some encoder-specific callbacks. Also, on this version we don't change the order we're writing the registers, making the code change safer. Signed-off-by:

As noticed by Daniel Vetter, intel_pipe_choose_bpp_dither should already check for invalid bpp values and set a valid value, so remove the recheck inside ironlake_crtc_mode_set and also replace a "default" switch case inside ironlake_set_pipeconf with a BUG(). Signed-off-by:

Manual backmerge of -rc7 to resolve a silent conflict leading to compile failure in drivers/gpu/drm/i915/intel_hdmi.c. This is due to the bugfix in -rc7: commit b98b6016 Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 07:43:22 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug Since this code moved around a lot in -next git put that snippet at the wrong spot. I've tried to fix this by making the conflict explicit by merging a version for next with: commit 3cce574f Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 11:19:00 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally But that failed to solve the entire problem. To avoid pushing out further -nightly branch to our QA where this is broken, do the backmerge and manually add the stuff git adds to -next from the patch in -fixes. Note that this doesn't show up in git's merge diff (and hence is also not handled by git rerere), which adds to the reasons why I'd like to fix this with a verbose backmerge. The git merge diff only shows a bunch of trivial conflicts of the "code changed in lines next to each another" kind. Signed-off-by:
