2016-07-18drm/i915/kbl: Introduce the first official DMC for Kabylake.Rodrigo Vivi1-11/+19
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).

2016-07-18drm/i915: add missing condition for committing planes on crtcLionel Landwerlin1-0/+6
The i915 driver checks for color management properties changes as part of a plane update.

2016-07-18s390/cio/chp : Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-9/+2
The workqueue "chp_wq" is involved in performing pending configure tasks for channel paths. It has a single work item(&cfg_work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference.

2016-07-16net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndataFlorian Fainelli1-4/+5
The label lio_xmit_failed is used 3 times through liquidio_xmit() but it always makes a call to dma_unmap_single() using potentially uninitialized variables from "ndata" variable. Out of the 3 gotos, 2 run after ndata has been initialized, and had a prior dma_map_single() call. Fix this by adding a new error label: lio_xmit_dma_failed which does this dma_unmap_single() and then processed with the lio_xmit_failed fallthrough.

phy-sun4i-usb now has proper dr_mode handling, it always registers an extcon, and sends a notify with the mode (even when in peripheral- / host-only mode) at least once. So we can simply the sunxi musb glue by always registering its extcon notifier and relying on sunxi_musb_work() to enable vbus when in host-only mode.

2016-07-15mlxsw: spectrum: Prevent invalid ingress buffer mappingIdo Schimmel3-3/+19
Packets entering the switch are mapped to a Switch Priority (SP) according to their PCP value (untagged frames are mapped to SP 0). The packets are classified to a priority group (PG) buffer in the port's headroom according to their SP. The switch maintains another mapping (SP to IEEE priority), which is used to generate PFC frames for lossless PGs. This mapping is initialized to IEEE = SP % 8. Therefore, when mapping SP 'x' to PG 'y' we create a situation in which an IEEE priority is mapped to two different PGs: IEEE 'x' ---> SP 'x' ---> PG 'y' IEEE 'x' ---> SP 'x + 8' ---> PG '0' (default) Which is invalid, as a flow can use only one PG buffer. Fix this by mapping both SP 'x' and 'x + 8' to the same PG buffer.

Paolo Abeni fixes a bug by returning the actual work done, capped to weight - 1, since the core doesn't allow to return the full budget when the driver modifies the NAPI status. Guilherme Piccoli fixes an issue where the q_vector initialization routine sets the affinity _mask of a q_vector based on v_idx value. This means a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value.

2016-07-16media: fix airspy usb probe error pathJames Patrick-Evans1-2/+1
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.

This patch enables a workaround for a mid thread preemption issue where a hardware timing problem can prevent the context restore from happening, leading to a hang. v2: move to gen9_init_workarounds (Arun) v3: move to start of gen9_init_workarounds (Arun) Signed-off-by: Tim Gore <[email protected]> Reviewed-by: Arun Siluvery <[email protected]> Signed-off-by: Tvrtko Ursulin <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit a8ab5ed5e1bf856eceaab5579236de6f92822b9f) Signed-off-by: Mika Kuoppala <[email protected]>

Bspec states that we need to set nuke on modify all to prevent screen corruption with fbc on skl and kbl. v2: proper workaround name References: HSD#2227109, HSDES#1404569388 Cc: Ville Syrjälä <[email protected]> Signed-off-by: Mika Kuoppala <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 031cd8c85aefad31e7af91eba7bc4735a6dfcc79) Signed-off-by: Mika Kuoppala <[email protected]>
2016-07-15drm/i915/gen9: Add WaFbcWakeMemOnMika Kuoppala2-2/+5
Set bit 8 in 0x43224 to prevent screen corruption and system hangs on high memory bandwidth conditions. The same wa also suggest setting bit 31 on ARB_CTL. According to another workaround we gain better idle power savings when FBC is enabled. v2: use correct workaround name v3: split out overlapping wa for corruption avoidance (Ville) References: HSD#2137218, HSD#2227171, HSD#2136579, BSID#883 Cc: Paulo Zanoni <[email protected]> Cc: Ville Syrjälä <[email protected]> Signed-off-by: Mika Kuoppala <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 303d4ea522e8672a1b62d968a5b6764929adc292) Signed-off-by: Mika Kuoppala <[email protected]>
