2018-10-05drm/i915: Redefine some Whiskey Lake SKUsRodrigo Vivi
commit 'b9be78531d27 ("drm/i915/whl: Introducing Whiskey Lake platform")' introduced WHL by moving some of CFL IDs here and using the Spec information of "U43" for most of IDs what appeared to be GT3. However when propagating the change to Mesa, Lionel noticed that based on number of execution unities the classification here seems at least strange. So, let's move for now with the information we trust more: the number of EUs. So we are able to propagate this change across the stack without getting stuck forever.

With armada the last bigger driver that realistically needed these to convert from legacy kms to atomic is converted. These helpers have been broken more often than not the past 2 years, and as this little patch series shows, tricked a bunch of people into using the wrong helpers for their functions.

2018-10-05media: cec: fix the Signal Free Time calculationHans Verkuil
The calculation of the Signal Free Time in the framework was not correct. If a message was received, then the next transmit should be considered a New Initiator and use a shorter SFT value. This was not done with the result that if both sides where continually sending messages, they both could use the same SFT value and one side could deny the other side access to the bus. Note that this fix does not take the corner case into account where a receive is in progress when you call adap_transmit.

2018-10-05media: cec: add new tx/rx status bits to detect aborts/timeoutsHans Verkuil
If the HDMI cable is disconnected or the CEC adapter is manually unconfigured, then all pending transmits and wait-for-replies are aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED). If due to (usually) a driver bug a transmit never ends (i.e. the transmit_done was never called by the driver), then when this times out the message is marked with CEC_TX_STATUS_TIMEOUT. This should not happen and is an indication of a driver bug. Without a separate status bit for this it was impossible to detect this from userspace. The 'transmit timed out' kernel message is now a warning, so this should be more prominent in the kernel log as well.

2018-10-05net_sched: convert idrinfo->lock from spinlock to a mutexCong Wang
In commit ec3ed293e766 ("net_sched: change tcf_del_walker() to take idrinfo->lock") we move fl_hw_destroy_tmplt() to a workqueue to avoid blocking with the spinlock held. Unfortunately, this causes a lot of troubles here: 1. tcf_chain_destroy() could be called right after we queue the work but before the work runs. This is a use-after-free. 2. The chain refcnt is already 0, we can't even just hold it again. We can check refcnt==1 but it is ugly. 3. The chain with refcnt 0 is still visible in its block, which means it could be still found and used! 4. The block has a refcnt too, we can't hold it without introducing a proper API either. We can make it working but the end result is ugly. Instead of wasting time on reviewing it, let's just convert the troubling spinlock to a mutex, which allows us to use non-atomic allocations too.

quality field is currently documented as being 'per mill'. In fact the math involved is: add_hwgenerator_randomness((void *)rng_fillbuf, rc, rc * current_quality * 8 >> 10); thus the actual definition is "bits of entropy per 1024 bits of input". The current documentation seems to have confused multiple people in the past, let's fix the documentation to match code. An alternative is to change core to match driver expectations, replacing rc * current_quality * 8 >> 10 with rc * current_quality / 1000 but that has performance costs, so probably isn't a good option.

This traffic scheduler allows traffic classes states (transmission allowed/not allowed, in the simplest case) to be scheduled, according to a pre-generated time sequence. This is the basis of the IEEE 802.1Qbv specification. Example configuration: tc qdisc replace dev enp3s0 parent root handle 100 taprio \ num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \ queues 1@0 1@1 2@2 \ base-time 1528743495910289987 \ sched-entry S 01 300000 \ sched-entry S 02 300000 \ sched-entry S 04 300000 \ clockid CLOCK_TAI The configuration format is similar to mqprio. The main difference is the presence of a schedule, built by multiple "sched-entry" definitions, each entry has the following format: sched-entry <CMD> <GATE MASK> <INTERVAL> The only supported <CMD> is "S", which means "SetGateStates", following the IEEE 802.1Qbv-2015 definition (Table 8-6). <GATE MASK> is a bitmask where each bit is a associated with a traffic class, so bit 0 (the least significant bit) being "on" means that traffic class 0 is "active" for that schedule entry. <INTERVAL> is a time duration in nanoseconds that specifies for how long that state defined by <CMD> and <GATE MASK> should be held before moving to the next entry. This schedule is circular, that is, after the last entry is executed it starts from the first one, indefinitely. The other parameters can be defined as follows: - base-time: specifies the instant when the schedule starts, if 'base-time' is a time in the past, the schedule will start at base-time + (N * cycle-time) where N is the smallest integer so the resulting time is greater than "now", and "cycle-time" is the sum of all the intervals of the entries in the schedule; - clockid: specifies the reference clock to be used; The parameters should be similar to what the IEEE 802.1Q family of specification defines.

2018-10-04cgroup: Fix dom_cgrp propagation when enabling threaded modeTejun Heo
A cgroup which is already a threaded domain may be converted into a threaded cgroup if the prerequisite conditions are met. When this happens, all threaded descendant should also have their ->dom_cgrp updated to the new threaded domain cgroup. Unfortunately, this propagation was missing leading to the following failure. # cd /sys/fs/cgroup/unified # cat cgroup.subtree_control # show that no controllers are enabled # mkdir -p mycgrp/a/b/c # echo threaded > mycgrp/a/b/cgroup.type At this point, the hierarchy looks as follows: mycgrp [d] a [dt] b [t] c [inv] Now let's make node "a" threaded (and thus "mycgrp" s made "domain threaded"): # echo threaded > mycgrp/a/cgroup.type By this point, we now have a hierarchy that looks as follows: mycgrp [dt] a [t] b [t] c [inv] But, when we try to convert the node "c" from "domain invalid" to "threaded", we get ENOTSUP on the write(): # echo threaded > mycgrp/a/b/c/cgroup.type sh: echo: write error: Operation not supported This patch fixes the problem by * Moving the opencoded ->dom_cgrp save and restoration in cgroup_enable_threaded() into cgroup_{save|restore}_control() so that mulitple cgroups can be handled. * Updating all threaded descendants' ->dom_cgrp to point to the new dom_cgrp when enabling threaded mode.

2018-10-04media: v4l: fwnode: Update V4L2 fwnode endpoint parsing documentationSakari Ailus
The semantics of v4l2_fwnode_endpoint_parse() and v4l2_fwnode_endpoint_alloc_parse() have changed slightly: they now take the bus type from the user as well as a default configuration for the bus that shall reflect the DT binding defaults. Document this.

2018-10-04media: v4l: fwnode: Initialise the V4L2 fwnode endpoints to zeroSakari Ailus
Initialise the V4L2 fwnode endpoints to zero in all drivers using v4l2_fwnode_endpoint_parse(). This prepares for setting default endpoint flags as well as the bus type. Setting bus type to zero will continue to guess the bus among the guessable set (parallel, Bt.656 and CSI-2 D-PHY).
