2014-06-18drm/i915: dp: fix order of dp aux i2c device cleanupImre Deak
commit 80f65de3c9b8101c1613fa82df500ba6a099a11c upstream. Atm we set the parent of the dp i2c device to be the correspondig connector device. During driver cleanup we first remove the connector device through intel_modeset_cleanup()->drm_sysfs_connector_remove() and only after that the i2c device through the encoder's destroy callback. This order is not supported by the device core and we'll get a warning, see the below bugzilla ticket. The proper order is to remove first any child device and only then the parent device. The first part of the fix changes the i2c device's parent to be the drm device. Its logical owner is not the connector anyway, but the encoder. Since the encoder doesn't have a device object, the next best choice is the drm device. This is the same what we do in the case of the sdvo i2c device and what the nouveau driver does. The second part creates a symlink in the connector's sysfs directory pointing to the i2c device. This is so, that we keep the current ABI, which also makes sense in case someone wants to look up the i2c device belonging to a specific connector.

2014-06-18drm/i915: add unregister callback to connectorImre Deak
commit 4932e2c3c716067f3580e1a9687bed9d751549e3 upstream. Since commit d9255d57147e1dbcebdf6670409c2fa0ac3609e6 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date:   Thu Sep 26 20:05:59 2013 -0300 it became clear that we need to separate the unload sequence into two parts: 1. remove all interfaces through which new operations on some object (crtc, encoder, connector) can be started and make sure all pending operations are completed 2. do the actual tear down of the internal representation of the above objects The above commit achieved this separation for connectors by splitting out the sysfs removal part from the connector's destroy callback and doing this removal before calling drm_mode_config_cleanup() which does the actual tear-down of all the drm objects. Since we'll have to customize the interface removal part for different types of connectors in the upcoming patches, add a new unregister callback and move the interface removal part to it. No functional change.

2014-06-18drm/i915: Only copy back the modified fields to userspace from execbufferChris Wilson
commit 9aab8bff7aa3bee567213ad3c1fdfb217bb980a2 upstream. We only want to modifiy a single field in the userspace view of the execbuffer command buffer, so explicitly change that rather than copy everything back again. This serves two purposes: 1. The single fields are much cheaper to copy (constant size so the copy uses special case code) and much smaller than the whole array. 2. We modify the array for internal use that need to be masked from the user. Note: We need this backported since without it the next bugfix will blow up when userspace recycles batchbuffers and relocations.

2014-06-18drm/i915: Fix unsafe loop iteration over vma whilst unbinding themChris Wilson
This is commit df6f783a4ef6790780a67c491897ac upstream. On non-LLC platforms, when changing the cache level of an object, we may need to unbind it so that prefetching across page boundaries does not cross into a different memory domain.

2014-06-18drm/i915: move power domain init earlier during system resumeImre Deak
This is commit 76c4b250080fff6e4befaa36199424 upstream. During resume the intel hda audio driver depends on the i915 driver reinitializing the audio power domain. Since the order of calling the i915 resume handler wrt. that of the audio driver is not guaranteed, move the power domain reinitialization step to the resume_early handler. This is guaranteed to run before the resume handler of any other driver. The power domain initialization in turn requires us to enable the i915 pci device first, so move that part earlier too. Accordingly disabling of the i915 pci device should happen after the audio suspend handler ran. So move the disabling later from the i915 resume handler to the resume_late handler. v2: - move intel_uncore_sanitize/early_sanitize earlier too, so they don't get reordered wrt. intel_power_domains_init_hw() Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=76152 Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> [danvet: Add cc: stable and loud comments that this is just a hack.] [danvet: Fix "Should it be static?" sparse warning reported by Wu Fengguang's kbuilder.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-06-18drm/i915: Disable self-refresh for untiled fbs on i915gmDaniel Vetter
This is commit 2ab1bc9df01dbc19b55b2271100db7 upstream. Apparently it doesn't work. X-tiled self-refresh works flawlessly otoh. Apparently X still works correctly with linear framebuffers, so might just be an issue with the initial modeset. It's unclear whether this just borked wm setup from our side or a hw restriction, but just disabling gets things going.

2014-06-18drm/i915: restore backlight precision when converting from ACPIAaron Lu
commit 721e82c08c1afd6b47367b0e0c4a62140b0667f3 upstream. When we set backlight on behalf of ACPI opregion, we will convert the backlight value in the 0-255 range defined in opregion to the actual hardware level. Commit 22505b82a2 (drm/i915: avoid brightness overflow when doing scale) is meant to fix the overflow problem when doing the conversion, but it also caused a problem that the converted hardware level doesn't quite represent the intended value: say user wants maximum backlight level(255 in opregion's range), then we will calculate the actual hardware level to be: level = freq / max * level, where freq is the hardware's max backlight level(937 on an user's box), and max and level are all 255. The converted value should be 937 but the above calculation will yield 765. To fix this issue, just use 64 bits to do the calculation to keep the precision and avoid overflow at the same time.

2014-06-18drm/i915: Break encoder->crtc link separately in intel_sanitize_crtc()Egbert Eich
commit 7f1950fbb989e8fc5463b307e062b4529d51c862 upstream. Depending on the SDVO output_flags SDVO may have multiple connectors linking to the same encoder (in intel_connector->encoder->base). Only one of those connectors should be active (ie link to the encoder thru drm_connector->encoder). If intel_connector_break_all_links() is called from intel_sanitize_crtc() we may break the crtc connection of an encoder thru an inactive connector in which case intel_connector_break_all_links() will not be called again for the active connector if this happens to come later in the list due to: if (connector->encoder->base.crtc != &crtc->base) continue; in intel_sanitize_crtc(). This will however leave the drm_connector->encoder linkage for this active connector in place. Subsequently this will cause multiple warnings in intel_connector_check_state() to trigger and the driver will eventually die in drm_encoder_crtc_ok() (because of crtc == NULL). To avoid this remove intel_connector_break_all_links() and move its code to its two calling functions: intel_sanitize_crtc() and intel_sanitize_encoder(). This allows to implement the link breaking more flexibly matching the surrounding code: ie. in intel_sanitize_crtc() we can break the crtc link separatly after the links to the encoders have been broken which avoids above problem. This regression has been introduced in: commit 24929352481f085c5f85d4d4cbc919ddf106d381 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Jul 2 20:28:59 2012 +0200 drm/i915: read out the modeset hw state at load and resume time so goes back to the very beginning of the modeset rework. v2: This patch takes care of the concernes voiced by Chris Wilson and Daniel Vetter that only breaking links if the drm_connector is linked to an encoder may miss some links. v3: move all encoder handling to encoder loop as suggested by Daniel Vetter.

2014-06-18drm/i915: Don't WARN nor handle unexpected hpd interrupts on gmch platformsDaniel Vetter
commit 3ff04a160a891e56cdcee5c198d4c764d1c8c78b upstream. The status bits are unconditionally set, the control bits only enable the actual interrupt generation. Which means if we get some random other interrupts we'll bogusly complain about them. So restrict the WARN to platforms with a sane hotplug interrupt handling scheme. And even more important also don't attempt to process the hpd bit since we've detected a storm already. Instead just clear the bit silently. This WARN has been introduced in commit b8f102e8bf71cacf33326360fdf9dcfd1a63925b Author: Egbert Eich <eich@suse.de> Date: Fri Jul 26 14:14:24 2013 +0200 drm/i915: Add messages useful for HPD storm detection debugging (v2) before that we silently handled the hpd event and so partially defeated the storm detection. v2: Pimp commit message (Jani) Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Egbert Eich <eich@suse.de> Cc: bitlord <bitlord0xff@gmail.com> Reported-by: bitlord <bitlord0xff@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-06-18drm/i915: Don't check gmch state on inherited configsDaniel Vetter
commit 9953599bc02dbc1d3330e6a0bfc6c50e9dffcac6 upstream. ... our current modeset code isn't good enough yet to handle this. The scenario is: 1. BIOS sets up a cloned config with lvds+external screen on the same pipe, e.g. pipe B. 2. We read out that state for pipe B and assign the gmch_pfit state to it. 3. The initial modeset switches the lvds to pipe A but due to lack of atomic modeset we don't recompute the config of pipe B. -> both pipes now claim (in the sw pipe config structure) to use the gmch_pfit, which just won't work.

2014-06-18drm/i915: Allow user modes to exceed DVI 165MHz limitVille Syrjälä
commit 40478455fefdc0bde24ae872c3f88d58a1b0e435 upstream. In commit commit 6375b768a9850b6154478993e5fb566fa4614a9c Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.

2014-06-18drm/i915: Do not dereference pointers from ring buffer in evict eventSteven Rostedt
commit 9297ebf29ad9118edd6c0fedc84f03e35028827d upstream. The TP_printk() should never dereference any pointers, because the ring buffer can be read at some unknown time in the future. If a device no longer exists, it can cause a kernel oops. This also makes this event useless when saving the ring buffer in userspaces tools such as perf and trace-cmd. The i915_gem_evict_vm dereferences the vm pointer which may also not exist when the ring buffer is read sometime in the future.
