Ville pointed out that my assumption that no unsupported pixel format can get past the pipe config computation stage to the platform update_plane callbacks is wrong. The reason is that this function still checks the old fb->depth value instead of the new pixel_format. While checking with all the other places that use this I've noticed that intel_framebuffer_init already has all the platform checks we need, so replace those checks with a WARN_ON. Since fb->depth isn't set for YUV pixel formats and since we already can't create an fb with an rgb layout not support on the running platform I /think/ this patch doesn't fix any bug. But it surely looks better! v2: BGR formats are also only gen4+, so add the corresponding WARN_ON, too (Ville).

We've mostly switched over to the new more flexible schema, but there's one check left in the modeset code. Motivated by a question from Ville whether there's really no way an unsupported pixel_format can escape into our platform update_plane callbacks. v2: Ville noticed that the fb->depth check is redudant when we already check fb->pixel_format.

The old code only handled either 6bpc or 8bpc. Since it's easy to do, reorganize the code to be a bit more generic so that it can also handle 10bpc and 12bpc. Note that we still start with 8bpc, so there's no functional change. Also, since we no don't need to compute the 6BPC flag in the mode_valid callback, we can consolidate things a bit. That requires though that the link bw computation is moved up in the compute_config callback.

The procedure has now 3 steps: 1. Compute the bpp that the plane will output, this is done in pipe_config_set_bpp and stored into pipe_config->pipe_bpp. Also, this function clamps the pipe_bpp to whatever limit the EDID of any connected output specifies. 2. Adjust the pipe_bpp in the encoder and crtc functions, according to whatever constraints there are. 3. Decide whether to use dither by comparing the stored plane bpp with computed pipe_bpp. There are a few slight functional changes in this patch: - LVDS connector are now also going through the EDID clamping. But in a 2nd change we now unconditionally force the lvds bpc value - this shouldn't matter in reality when the panel setup is consistent, but better safe than sorry. - HDMI now forces the pipe_bpp to the selected value - I think that's what we actually want, since otherwise at least the pixelclock computations are wrong (I'm not sure whether the port would accept e.g. 10 bpc when in 12bpc mode). Contrary to the old code, we pick the next higher bpc value, since otherwise there's no way to make use of the 12 bpc mode (since the next patch will remove the 12bpc plane format, it doesn't exist). Both of these changes are due to the removal of the pipe_bpp = min(display_bpp, plane_bpp); statement. Another slight change is the reworking of the dp bpc code: - For the mode_valid callback it's sufficient to only check whether the mode would fit at the lowest bpc. - The bandwidth computation code is a bit restructured: It now walks all available bpp values in an outer loop and the codeblock that computes derived values (once a good configuration is found) has been moved out of the for loop maze. This is prep work to allow us to successively fall back on bpc values, and also correctly support bpc values != 8 or 6. v2: Rebased on top of Paulo Zanoni's little refactoring to use more drm dp helper functions. v3: Rebased on top of Jani's eDP bpp fix and Ville's limited color range work. v4: Remove the INTEL_MODE_DP_FORCE_6BPC #define, no longer needed. v5: Remove intel_crtc->bpp, too, and fix up the 12bpc check in the hdmi code. Also fixup the bpp check in intel_dp.c, it'll get reworked in a later patch though again. v6: Fix spelling in a comment. v7: Debug output improvements for the bpp computation. v8: Fixup 6bpc lvds check - dual-link and 8bpc mode are different things! v9: Reinstate the fix to properly ignore the firmware edp bpp ... this was lost in a rebase. v10: Both g4x and vlv lack 12bpc pipes, so don't enforce that we have that. Still unsure whether this is the way to go, but at least 6bpc for a 8bpc hdmi output seems to work. v11: And g4x/vlv also lack 12bpc hdmi support, so only support high depth on DP. Adjust the code. v12: Rebased. v13: Split out the introduction of pipe_config->dither|pipe_bpp, as requested from Jesse Barnes. v14: Split out the special 6BPC handling for DP, as requested by Jesse Barnes.

Only used by the lvds encoder. Note that we shouldn't do the same simple conversion with the FORCE_6BPC flag, since that's much better handled by moving all the pipe_bpc computation around. This requires that we pass the pipe config around to encoders, so that they can set special attributes and set constraints. To do so introduce a new ->compute_config encoder callback, which is called in stead of the drm crtc helper's ->mode_fixup. To avoid massive churn all over the codebase we don't want to convert all existing ->mode_fixup functions. Instead I've opted to convert them on an as-needed basis (mostly to cut down on rebase conflicts and to have more freedom to experiment around while developing the patches).

The i915 driver uses sg lists for memory without backing 'struct page' pages, similarly to other IO memory regions, setting only the DMA address for these. It does this, so that it can program the HW MMU tables in a uniform way both for sg lists with and without backing pages. Without a valid page pointer we can't call nth_page to get the current page in __sg_page_iter_next, so add a helper that relevant users can call separately. Also add a helper to get the DMA address of the current page (idea from Daniel). Convert all places in i915, to use the new API.

From the w/a database: 'To prevent false VT-d type 6 error: The primary display plane must be 256KiB aligned, and require an extra 128 PTEs of padding afterward; The sprites planes must be 128KiB aligned, and require an extra 64 PTEs of padding afterward; The cursors must be 64KiB aligned, and require an extra 2 PTEs of padding afterward.' As we use the same function to pin the primary and sprite planes, we can simply use the more strict requirements for scanouts for both. Instead of using explicit padding PTEs following the scanout objects, we should be able to use the scratch page that is always mapped into the unused PTEs to avoid the VT-d error.

The new init sequence is: 1. irq enabling 2. modeset init 3. hpd setup We need to move around the ibx setup a bit to fix this. Ville Syrjälä pointed out in his review that we can't touch SDEIER after the interrupt handler is set up, since that'll race with Paulo Zanoni's PCH interrupt race fix: commit 44498aea Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Fri Feb 22 17:05:28 2013 -0300 drm/i915: also disable south interrupts when handling them We fix that by unconditionally enabling all interrupts in SDEIER, but masking them as-needed in SDEIMR. Since only the single-threaded setup/teardown (or suspend/resume) code touches that, no further locking is required. While at it also simplify the mask handling - we start out with all interrupts cleared in the postinstall hook, and never enable a hpd interrupt before hpd_irq_setup is called. And finally, for consistency rename the ibx hpd setup function to ibx_hpd_irq_setup. v2: Fix race around SDEIER writes (Ville). v3: Remove the superflous posting read for SDEIER, spotted by Ville. Ville also wondered whether we shouldn't clear SDEIIR, since now SDE interrupts are enabled before we have an irq handler installed.
