* drm/i915: take mode config lock around crtc disable at suspendJesse Barnes2013-11-261-0/+2
| | | | | | | | | | | | | | | | | This is just a theoretical issue, but we need to do this to prevent the WARN in pipe_from_connector at suspend time.

* drm/i915: Prefer setting PTE cache age to 3Chris Wilson2013-11-251-2/+4
| | | | | | | | | | | | | | | | | | | | | | | We have conflicting benchmark data that suggest either age 0 or age 3 is better. However, the earlier benchmark on which we based the switch to age 0 (commit 0d8ff15e9a15f2b393e53337a107b7a1e5919b6d Author: Ben Widawsky <benjamin.widawsky@intel.com> Date: Thu Jul 4 11:02:03 2013 -0700 drm/i915/hsw: Set correct Haswell PTE encodings) actually seems to prefer the default PTE encoding as age 3. Presumably, this is in part due to the use of MOCS to override the PTE encodings when appropriate.

* i915: Use 120MHz LVDS SSC clock for gen5/gen6/gen7Duncan Laurie2013-11-151-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had been using a DMI table workaround to select the right frequency for devices, but this is fragile and must be updated with every new platform. Instead the default case when VBT is missing is changed to use 120MHz clock for LVDS SSC for these generations. The docs for 2010-Core, SandyBridge, and IvyBridge all indicate that the reference frequency for LVDS is 120MHz: "2010 Core" http://intellinuxgraphics.org/IHD_OS_Vol3_Part3r2.pdf page 38 Reference Frequency: 120MHz for CRT and LVDS. 100MHz for the FDI.

From a kernel driver pov there's two areas with big changes in Broadwell: - Completely new enumerated interrupt bits. On the plus side it now looks fairly unform and sane. - Completely new pagetable layout. To ensure minimal impact on existing platforms we've refactored both the irq and low-level gtt handling code a lot in anticipation of the bdw push. So now bdw enabling in these areas just plugs in a bunch of vfuncs. Otherwise it's all fairly harmless adjusting of switch cases and if-ladders to shovel bdw into the right blocks. So minimized impact on existing platforms. I've also merged the bdw-stage1 branch into our -nightly integration branch for the past week to make sure we don't break anything. Note that there's still quite a flurry or patches floating around, but I've figured I'll push this out. I plan to keep the bdw fixes separate from my usual -fixes stream so that you can reject them easily in case it still looks like too much churn. Also, bdw is for now hidden behind the preliminary hw enabling module option. So there's no real pressure to get follow-up patches all into 3.13. * tag 'bdw-stage1-2013-11-08-v2' of git://people.freedesktop.org/~danvet/drm-intel: (75 commits) drm/i915: Mask the vblank interrupt on bdw by default drm/i915: Wire up cpu fifo underrun reporting support for bdw drm/i915: Optimize gen8_enable|disable_vblank functions drm/i915: Wire up pipe CRC support for bdw drm/i915: Wire up PCH interrupts for bdw drm/i915: Wire up port A aux channel drm/i915: Fix up the bdw pipe interrupt enable lists drm/i915: Optimize pipe irq handling on bdw drm/i915/bdw: Take render error interrupt out of the mask drm/i915/bdw: Add BDW PCH check first drm/i915: Use hsw_crt_get_config on BDW drm/i915/bdw: Change dp aux timeout to 600us on DDIA drm/i915/bdw: Enable trickle feed on Broadwell drm/i915/bdw: WaSingleSubspanDispatchOnAALinesAndPoints drm/i915/bdw: conservative SBE VUE cache mode drm/i915/bdw: Limit SDE poly depth FIFO to 2 drm/i915/bdw: Sampler power bypass disable ddrm/i915/bdw: Disable centroid pixel perf optimization drm/i915/bdw: BWGTLB clock gate disable drm/i915/bdw: Implement edp PSR workarounds ...

Also stop enabling the port A hotplug event - eDP panels are expected to fire that interupt and we're not really ready to deal with them. This is consistent with how we handle port A on ilk-hsw. The more important bit is that we must delay the enabling of hotplug interrupts until all the encoders are fully set up. But we need irq support earlier than that, hence hotplug interrupts can only be enabled in the ->hpd_irq_setup callback. v2: Drop the _HOTPLUG, it isn't (Ville).

So drop it for now. - CRC error is a special mode of the CRC hardware that we don't use, so again drop it. Real CRC support for bdw will be added later. - All the other error bits are about faults, so rename the #define and adjust the output. v2: Use pipe_name as pointed out by Ville.
