Merge tag 'topic/kbl-4.7-fixes-2016-07-18' of git://anongit.freedesktop.org/drm-intel into drm-fixes As promised here's the pile of kbl cherry-picks assembled by Mika&Rodrigo. It's a bit much, but all well-contained to kbl code and been tested for a while in drm-intel-next. Still separate in case too much, but in that case I think we'd need to disable kbl by default again (which would be annoying too) in 4.7. * tag 'topic/kbl-4.7-fixes-2016-07-18' of git://anongit.freedesktop.org/drm-intel: (28 commits) drm/i915/kbl: Introduce the first official DMC for Kabylake. drm/i915: Introduce Kabypoint PCH for Kabylake H/DT. drm/i915/gen9: implement WaConextSwitchWithConcurrentTLBInvalidate drm/i915/gen9: Add WaFbcHighMemBwCorruptionAvoidance drm/i195/fbc: Add WaFbcNukeOnHostModify drm/i915/gen9: Add WaFbcWakeMemOn drm/i915/gen9: Add WaFbcTurnOffFbcWatermark drm/i915/kbl: Add WaClearSlmSpaceAtContextSwitch drm/i915/gen9: Add WaEnableChickenDCPR drm/i915/kbl: Add WaDisableSbeCacheDispatchPortSharing drm/i915/kbl: Add WaDisableGafsUnitClkGating drm/i915/kbl: Add WaForGAMHang drm/i915: Add WaInsertDummyPushConstP for bxt and kbl drm/i915/kbl: Add WaDisableDynamicCreditSharing drm/i915/kbl: Add WaDisableGamClockGating drm/i915/gen9: Enable must set chicken bits in config0 reg drm/i915/kbl: Add WaDisableLSQCROPERFforOCL drm/i915/kbl: Add WaDisableSDEUnitClockGating drm/i915/kbl: Add WaDisableFenceDestinationToSLM for A0 drm/i915/kbl: Add WaEnableGapsTsvCreditFix ...

Version 1.01. This firmware is made for Kabylake platform so it doesn't need the stepping workaround that we had before. v2: Rebased on top of latest nightly with min version required change. v3: With right CSR_VERSION (Patrik).

The i915 driver checks for color management properties changes as part of a plane update. Therefore a color management update must imply a plane update, otherwise we never update the transformation matrixes and degamma/gamma LUTs. v2: add comment about moving the commit of color management registers to an async worker v3: Commit color management register right after vblank v4: Move back color management commit condition together with planes commit v5: Trigger color management commit through the planes commit (Daniel) v6: Make plane change update more readable Fixes: 20a34e78 (drm/i915: Update color management during vblank evasion.)

eDP should be treated as connected even if doesn't have an EDID. In that case we'll use the timings from the VBT. That used to be the case until commit f21a2198 ("drm/i915: Splitting intel_dp_detect") broke things by considering even eDP disconnected if we fail to get an EDID for it. Fix things up again by treating eDP as always connected.

Without this check, the following XFS_I invocations would return bad pointers when used on non-XFS inodes (perhaps pointers into preceding allocator chunks). This could be used by an attacker to trick xfs_swap_extents into performing locking operations on attacker-chosen structures in kernel memory, potentially leading to code execution in the kernel. (I have not investigated how likely this is to be usable for an attack in practice.) Signed-off-by:

Fix a memory leak on probe error of the airspy usb device driver. The problem is triggered when more than 64 usb devices register with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV. The memory leak is caused by the probe function of the airspy driver mishandeling errors and not freeing the corresponding control structures when an error occours registering the device to v4l2 core. A badusb device can emulate 64 of these devices, and then through continual emulated connect/disconnect of the 65th device, cause the kernel to run out of RAM and crash the kernel, thus causing a local DOS vulnerability.

In commit 2c1ea4c7 ("EDAC, sb_edac: Use cpu family/model in driver detection") I broke Knights Landing because I failed to notice that it called a wrapper macro "sbridge_get_all_devices_knl" instead of "sbridge_get_all_devices" like all the other types. Now that we include the processor type in the pci_id_table structure we can skip the wrappers and just have the sbridge_get_all_devices() check the type to decide whether to allow duplicate devices and controllers to have registers spread across buses.

Some Kabylake SKUs are going to use Kabypoint PCH. It is mainly for Halo and DT ones. >From our specs it doesn't seem that KBP brings any change on the display south engine. So let's consider this as a continuation of SunrisePoint, i.e., SPT+. Since it is easy to get confused by a letter change: KBL = Kabylake - CPU/GPU codename. KBP = Kabypoint - PCH codename.

Past evidence with system hangs and hsds tie WaForceEnableNonCoherent and WaDisableHDCInvalidation to WaForceContextSaveRestoreNonCoherent. Documentation states that WaForceContextSaveRestoreNonCoherent would not be needed on skl past E0 but evidence proved otherwise. See commit <510650e8> ("drm/i915/skl: Fix spurious gpu hang with gt3/gt4 revs"). In this scope consider kbl to be skl with a bigger revision than E0 so play it safe and bind these two workarounds to the WaForceContextSaveRestoreNonCoherent, and apply to all gen9. v2: fix comment (Matthew) References: HSD#2134449, HSD#2131413 Signed-off-by:
