No more need to guard the write with a power well check on Haswell now that we have proper pfit state readout: We can simply only clear the pfit if it's actually on. This removes some duplication of knowledge between the haswell pfit disable and pfit state readout code about. While at it extract a little helper for this. Reviewed-by:

Pfit state readout is a bit ugly on gen2/3 due to the intermingling with the lvds state, but alas. Also note that since state is always cleared to zero we can unconditonally compare all the state and completely neglect the actual platform we're running on. v2: Properly check for the pfit power domain on haswell. v3: Don't check pgm_ratios on gen4+, they're auto-computed by the hw. v4: Properly clear the lvds border bits, upset the state checker a bit. v5: Unconditionally read out panel dither settings on gen2/3.

Up to now, we were using a static table to match the clock frequency with a (r2,n2,p) triplet. Despite this table being big, it's by no mean comprehensive and we had to fall back to the closest frequency when the requested TMDS clock wasn't in the table. This patch computes (r2,n2,p) dynamically and get rid of The Big Table. v2: Replace the floating point constant 1e6 by 1000000 Bugzilla: http://bugs.freedesktop.org/show_bug.cgi?id=58497Signed-off-by:

This patch introduce Frame Buffer Compression (FBC) support for IVB, without enabling it by default. It adds a new function gen7_enable_fbc to avoid getting ironlake_enable_fbc messed with many IS_IVYBRIDGE checks. v2: Fixes from Ville. * Fix Plane. FBC is tied to primary plane A in HSW * Fix DPFC initial write to avoid let trash on the register. v3: Checking for bad plane on intel_update_fbc() as Chris suggested. v4: Ville pointed out that according to BSpec FBC_CTL bits 0:3 must be 0. v5: Up to v4 this work was entirely focused on Haswell. However Ville noticed I could reuse the FBC work done for HSW and get FBC for free at Ivybridge. So it makes more sense enable FBC for IVB first. FBC for HSW comming on next patches. We are just not enabling it by default on IVB. v6: Fix confused commit name (by Matt Turner). v7: Remove gtt_offset shift since it is page aligned byte offset (by Ville).

This seems to be an impressive piece of copy&pasta lore. I've checked all docs and on most platforms these bits are all MBZ, with the exception of the SDVO pixel multiplier on gen3. On gen4 that moved to a special DPLL_MD registers. No indication whatsoever that we actually need this for native TV-out support. I suspect this started as a hack when we didn't yet have proper pixel multiplier support in place for SDVO TV, but then got stuck in a life of its own. Just rip it out. Reviewed-by:

Daniel Vetter authored
TV-out uses the same reference clock as everyone else. The only difference seems to be in the slightly different CB tuning limit. Note that PLL_REF_INPUT_TVCLKINBC is a reserved value on ilk+. Also strictly speaking we don't support native TV-out on ilk+, hence all that code is dead. But Bspec still contains some residual mentions of native TV-out on some pch-split platforms, so I've figured it doesn't hurt to keep the code around a bit longer (e.g. in the cb tune function). v2: Improve the commit message as Jani suggested in his review.

We have a very nice infrastructure for this now! Note that the multifunction sdvo support is pretty neatly broken: We completely ignore userspace's request for which connector to wire up with the encoder and just use whatever the last detect callback has seen. Not something I'll fix in this patch, but unfortunately something which is also broken in the DDI code ... v2: Don't call sdvo_tv_clock twice. Reviewed-by:

commit 142e2398 Author: Egbert Eich <eich@suse.de> Date: Thu Apr 11 15:57:57 2013 +0200 drm/i915: Add bit field to record which pins have received HPD events (v3) added a bit field for hotplug event tracking. There ended up being three different v3 of the patch: [1], [2], and [3]. Apparently [1] was the correct one, but some frankenstein combination of the three got committed, which reversed the logic for setting the hotplug bits and misplaced a continue statement, skipping the hotplug irq storm handling altogether. This lead to broken hotplug detection, bisected to commit 321a1b30 Author: Egbert Eich <eich@suse.de> Date: Thu Apr 11 16:00:26 2013 +0200 drm/i915: Only reprobe display on encoder which has received an HPD event (v2) which uses the incorrectly set hotplug event bits.

In the error state function we read the registers without checking if the power well is on, so after doing this we have to clear the FPGA_DBG_RM_NOCLAIM bit to prevent the next I915_WRITE from detecting it and printing an error message. The first version of this patch was checking for the power well state and then avoiding reading registers that were off, but the reviewers requested to just read the registers any way and then later clear the FPGA_DBG_RM_NOCLAIM bit.
