Update rs-fw API to match changes in FW. Specifically, the TLC_MNG_NOTIF_REQ_CMD command and TLC_MNG_AMSDU_ENABLE_NOTIF notification are removed, the A-MSDU related info is received from FW via the TLC_MNG_UPDATE_NOTIF, and the TLC_MNG_CONFIG_CMD uses version 2 of its data structure. Additionally, constify some arguments in a couple of functions. Signed-off-by: Naftali Goldstein <naftali.goldstein@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

22000 devices rely on this flag to install the key to the right queues. For earlier devices we didn't have a key / queue mapping and the key was sent along with the Tx command for each Tx hence the problem didn't arise.

Avoid a race where two (or more) commands get the same index: 1. T1 calls enqueue_hcmd and the local TFD index is assigned to txq->write_ptr; 2. Context switch 'before incrementing txq->write_ptr'; 3. T2 calls enqueue_hcmd and the local TFD index is assigned to txq->write_ptr; 4. Now the index is set to the same value for both commands of T1 and T2. To prevent this from happening, set the local TFD index inside the critical section (the index is set by global txq write pointer).

When we enable TSO, we can have a lot of packets in the operation mode that will be pushed to the transport no matter what is the queue's fullness state. To cope with that the transport can buffer those packets and add them to the ring later when there is more room. This implementation was missing in the Gen2 devices' code.

Johannes Berg authored
Introduce and use iwl_mvm_cdb_scan_api(), which checks the family. Most of this will go away once the 22000 firmware supports adaptive dwell, after which the V6 scan API won't be used, but the V3 scan *config* API will still need to be distinguished. In any case, this gets rid of the completely bogus has_new_tx_api() checks. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

Try to detect that the AP is not using aggregation even when there's enough traffic to make it worthwhile; if this is the case and U-APSD is enabled then assume the AP is broken (like so many) and doesn't enable aggregation when U-APSD is used. In this case, disconnect from the AP and blacklist U-APSD for a potential new connection to it.

The primary channel is the channel that will be untouched by BT. The secondary channel might be touched by BT. Hence, we want the primary to be the most active channel. To do so, use the TCM infrastructure. Since the BT keeps sending notifications, we can rely on them to trigger the check. Every 10 seconds, we will check what is the most active context and chose the right primary. We need to wait 10 seconds before we modify the settings because frequent changes in these settings can confuse BT.

Pull asm-generic fixes from Arnd Bergmann: "I have one regression fix for a minor build problem after the architecture removal series, plus a rework of the barriers in the readl/writel functions, thanks to work by Sinan Kaya: This started from a discussion on the linuxpcc and rdma mailing lists[1]. To summarize, we decided that architectures are responsible to serialize readl() and writel() accesses on a device MMIO space relative to DMA performed by that device. This series provides a pessimistic implementation of that behavior for asm-generic/io.h, which is in turn used by a number of architectures (h8300, microblaze, nios2, openrisc, s390, sparc, um, unicore32, and xtensa). Some of those presumably need no extra barriers, or something weaker than rmb()/wmb(), and they are advised to override the new default for better performance. For inb()/outb(), the same barriers are used, but architectures might want to add another barrier to outb() here if that can guarantee non-posted behavior (some architectures can, others cannot do that). The readl_relaxed()/writel_relaxed() family of functions retains the existing behavior with no extra barriers" [1] https://lists.ozlabs.org/pipermail/linuxppc-dev/2018-March/170481.html * tag 'asm-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: io: change writeX_relaxed() to remove barriers io: change readX_relaxed() to remove barriers dts: remove cris & metag dts hard link file io: change inX() to have their own IO barrier overrides io: change outX() to have their own IO barrier overrides io: define stronger ordering for the default writeX() implementation io: define stronger ordering for the default readX() implementation io: define several IO & PIO barrier types for the asm-generic version

Pull more power management updates from Rafael Wysocki: "These include one big-ticket item which is the rework of the idle loop in order to prevent CPUs from spending too much time in shallow idle states. It reduces idle power on some systems by 10% or more and may improve performance of workloads in which the idle loop overhead matters. This has been in the works for several weeks and it has been tested and reviewed quite thoroughly. Also included are changes that finalize the cpufreq cleanup moving frequency table validation from drivers to the core, a few fixes and cleanups of cpufreq drivers, a cpuidle documentation update and a PM QoS core update to mark the expected switch fall-throughs in it. Specifics: - Rework the idle loop in order to prevent CPUs from spending too much time in shallow idle states by making it stop the scheduler tick before putting the CPU into an idle state only if the idle duration predicted by the idle governor is long enough. That required the code to be reordered to invoke the idle governor before stopping the tick, among other things (Rafael Wysocki, Frederic Weisbecker, Arnd Bergmann). - Add the missing description of the residency sysfs attribute to the cpuidle documentation (Prashanth Prakash). - Finalize the cpufreq cleanup moving frequency table validation from drivers to the core (Viresh Kumar). - Fix a clock leak regression in the armada-37xx cpufreq driver (Gregory Clement). - Fix the initialization of the CPU performance data structures for shared policies in the CPPC cpufreq driver (Shunyong Yang). - Clean up the ti-cpufreq, intel_pstate and CPPC cpufreq drivers a bit (Viresh Kumar, Rafael Wysocki). - Mark the expected switch fall-throughs in the PM QoS core (Gustavo Silva)" * tag 'pm-4.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (23 commits) tick-sched: avoid a maybe-uninitialized warning cpufreq: Drop cpufreq_table_validate_and_show() cpufreq: SCMI: Don't validate the frequency table twice cpufreq: CPPC: Initialize shared perf capabilities of CPUs cpufreq: armada-37xx: Fix clock leak cpufreq: CPPC: Don't set transition_latency cpufreq: ti-cpufreq: Use builtin_platform_driver() cpufreq: intel_pstate: Do not include debugfs.h PM / QoS: mark expected switch fall-throughs cpuidle: Add definition of residency to sysfs documentation time: hrtimer: Use timerqueue_iterate_next() to get to the next timer nohz: Avoid duplication of code related to got_idle_tick nohz: Gather tick_sched booleans under a common flag field cpuidle: menu: Avoid selecting shallow states with stopped tick cpuidle: menu: Refine idle state selection for running tick sched: idle: Select idle state before stopping the tick time: hrtimer: Introduce hrtimer_next_event_without() time: tick-sched: Split tick_nohz_stop_sched_tick() cpuidle: Return nohz hint from cpuidle_select() jiffies: Introduce USER_TICK_USEC and redefine TICK_USEC ...

Guillaume Nault says: ==================== l2tp: tunnel creation fixes L2TP tunnel creation is racy. We need to make sure that the tunnel returned by l2tp_tunnel_create() isn't going to be freed while the caller is using it. This is done in patch #1, by separating tunnel creation from tunnel registration. With the tunnel registration code in place, we can now check for duplicate tunnels in a race-free way. This is done in patch #2, which incidentally removes the last use of l2tp_tunnel_find(). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Guillaume Nault authored
We can't use l2tp_tunnel_find() to prevent l2tp_nl_cmd_tunnel_create() from creating a duplicate tunnel. A tunnel can be concurrently registered after l2tp_tunnel_find() returns. Therefore, searching for duplicates must be done at registration time. Finally, remove l2tp_tunnel_find() entirely as it isn't use anywhere anymore.
