We want to compute this earlier. To avoid a big complicated patch, this patch here just does the big search&replace and still calls the old functions at the same places. Reviewed-by:

Now that we have a useful struct for this, let's use it. Some neat pointer-chasing required, but it's all there already. v2: Rebased on top of the added Haswell limited color range support. Reviewed-by:

This is used way too often in the enable/disable paths. And will be even more useful in the future. Note that correct semantics of this change highly depend upon correct updating of intel_crtc->config: Like with all other modeset state, we need to call ->disable with the old config, but ->mode_set and ->enable with the new config. v2: Do not yet use the flag in the ->disable callbacks - atm we don't yet have support for the information stored in the pipe_config in the hw state readout code, so this will be wrong at boot-up/resume. v3: Rebased on top of the hdmi/dp ddi encoder merging. v4: Fixup stupid rebase error which lead to a NULL vfunc deref. v5: On haswell the VGA port is on the PCH! v6: s/IS_HASWELL/HAS_DDI/, spotted by Paulo Zanoni. Also add a missing parameter name in a function declaration. v7: Don't forget to git add ... Reviewed-by:

Completely unused by now. Separate patch in case I've missed a place somewhere which dereferences the helper vtable but actually shouldn't do so. v2: Resolve rebase conflict with Egbert Eich's hpd infrastructure rework. Reviewed-by:

Used by SDVO (and hopefully, eventually HDMI, if we ever get around to fixing up the low dotclock CEA modes ...). This required adding a new encoder->mode_set callback to be able to pass around the intel_crtc_config. Reviewed-by:

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). Reviewed-by:

To make decent modeset state checking possible (e.g. for the check mode with atomic modesetting) we want to have the full pipe configuration and state checks done before we touch the hw. To ensure that all the little bits&pieces that are now moved to the pipe_config handle this correctly, move its computation to the right spot now, before we touch the hw in the disable_pipes step.

Currently only containing the requested and the adjusted mode. And only crtc callbacks are converted somewhat to it, encoders will be done on a as-needed basis (simply too much churn in one patch otherwise). Future patches will add tons more useful stuff to this struct, starting with the very simple. v2: Store the pipe_config in the intel_crtc, so that the ->mode-set, ->enable and also ->disable have easy access to it. v3: Store the pipe config in the right crtc ... v4: Rebased. v5: Fixup an OOPS when trying to kfree an ERR_PTR. v6: Used drm_moode_copy and some other small cleanups as suggested by Ville Syrjälä. v7: drm_mode_copy preserves the mode id of the destination, so no need to clear it again (Ville). v8: Break a long line spotted by Paulo.

The backlight device .get_brightness callback is supposed to return the actual brightness by querying the hardware, not the cached value. See Documentation/ABI/stable/sysfs-class-backlight. The callback is there to support the actual_brightness sysfs file. With the backlight_level and backlight device brightness now in sync, one can reliably get the cached value through the brightness sysfs file. Signed-off-by:

A single point of truth would be better than two, but achieving that would require more abstractions for CONFIG_BACKLIGHT_CLASS_DEVICE=n with not a whole lot of real benefits. Take the short route and just keep the backlight levels in sync. In particular, update backlight device brightness on opregion brightness changes. Signed-off-by:

Now with Egbert Eich's hpd infrastructure rework merged this is dead simple. And we need this to make output detection work on SDVO - with the cleaned-up drm polling helpers outputs which claim to have hpd support are no longer polled. Now SDVO claims to do that, but it's not actually wired up. So just do it. Reviewed-by:

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. Signed-off-by:

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.

After "Convert HPD interrupts to make use of HPD pin assignment in encoders." This function is now basically the same as i915_hpd_irq_setup(). Consolidating both functions in one requires one more check for I915_HAS_HOTPLUG(dev) in the i965 code path and one more check for IS_G4X(dev) in the i915 code path. These are considered harmless.

This fixes a regression introduced in commit e5868a31 Author: Egbert Eich <eich@suse.de> Date: Thu Feb 28 04:17:12 2013 -0500 DRM/i915: Convert HPD interrupts to make use of HPD pin assignment in encode Due to the irq setup rework in 3.9, see commit 20afbda2 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Dec 11 14:05:07 2012 +0100 drm/i915: Fixup hpd irq register setup ordering Egbert Eich's hpd rework blows up on pch-split platforms - it walks the encoder list before that has been set up completely. 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. But the master interrupt control bit in DEIER is still cleared, so we should be fine.
