2021-02-08ice: Add initial support framework for LAGDave Ertman
Add the framework and initial implementation for receiving and processing netdev bonding events. This is only the software support and the implementation of the HW offload for bonding support will be coming at a later time. There are some architectural gaps that need to be closed before that happens. Because this is a software only solution that supports in kernel bonding, SR-IOV is not supported with this implementation.

2021-02-08ice: Remove xsk_buff_pool from VSI structureMichal Swiatkowski
Current implementation of netdev already contains xsk_buff_pools. We no longer have to contain these structures in ice_vsi. Refactor the code to operate on netdev-provided xsk_buff_pools. Move scheduling napi on each queue to a separate function to simplify setup function.

2021-02-08ice: implement new LLDP filter commandDave Ertman
There is an issue with some NVMs where an already existent LLDP filter is blocking the creation of a filter to allow LLDP packets to be redirected to the default VSI for the interface. This is blocking all LLDP functionality based in the kernel when the FW LLDP agent is disabled (e.g. software based DCBx). Implement the new AQ command to allow adding VSI destinations to existent filters on NVM versions that support the new command. The new lldp_fltr_ctrl AQ command supports Rx filters only, so the code flow for adding filters to disable Tx of control frames will remain intact.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2021-02-04 Vlad Buslov says: ================= Implement support for VF tunneling Abstract Currently, mlx5 only supports configuration with tunnel endpoint IP address on uplink representor. Remove implicit and explicit assumptions of tunnel always being terminated on uplink and implement necessary infrastructure for configuring tunnels on VF representors and updating rules on such tunnels according to routing changes.

In order to achieve this for tx, TC implementation marks encap rules with tunnel endpoint on mlx5 VF of same eswitch with MLX5_ESW_DEST_CHAIN_WITH_SRC_PORT_CHANGE flag and adds header modification rule to overwrite packet source port to the value of tunnel VF. Eswitch code is modified to recirculate such packets after source port value is changed, which allows second tx rules to match. For rx path indirect table infrastructure is used to allow fully processing VF tunnel traffic in hardware. To implement such pipeline driver needs to program the hardware after matching on UL rule to overwrite source vport from UL to tunnel VF and recirculate the packet to the root table to allow matching on the rule installed on tunnel VF. For this, indirect table matches all encapsulated traffic by tunnel parameters and all other IP traffic is sent to tunnel VF by the miss rule. Such configuration will cause packet to appear on VF representor instead of VF itself if packet has been matches by indirect table rule based on tunnel parameters but missed on second rule (after recirculation). Handle such case by marking packets processed by indirect table with special 0xFFF value in reg_c1 and extending slow table with additional flow group that matches on reg_c0 (source port value set by indirect tables) and reg_c1 (special 0xFFF mark). When creating offloads fdb tables, install one rule per VF vport to match on recirculated miss packets and redirect them to appropriate VF vport. Routing events In order to support routing changes and migration of tunnel device between different endpoint VFs, implement routing infrastructure and update it with FIB events. Routing entry table is introduced to mlx5 TC. Every rx and tx VF tunnel rule is attached to a routing entry, which is shared for rules of same tunnel. On FIB event the work is scheduled to delete/recreate all rules of affected tunnel. Note: only vxlan tunnel type is supported by this series. =================

2021-02-08Bluetooth: btusb: Some Qualcomm Bluetooth adapters stop workingHui Wang
This issue starts from linux-5.10-rc1, I reproduced this issue on my Dell Inspiron 7447 with BT adapter 0cf3:e005, the kernel will print out: "Bluetooth: hci0: don't support firmware rome 0x31010000", and someone else also reported the similar issue to bugzilla #211571. I found this is a regression introduced by 'commit b40f58b97386 ("Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"), the patch assumed that if high ROM version is not zero, it is an adapter on WCN6855, but many old adapters don't need to load rampatch or nvm, and they have non-zero high ROM version. To fix it, let the driver match the rom_version in the qca_devices_table first, if there is no entry matched, check the high ROM version, if it is not zero, we assume this adapter is ready to work and no need to load rampatch and nvm like previously.

2021-02-08cpufreq: ACPI: Update arch scale-invariance max perf ratio if CPPC is not thereRafael J. Wysocki
If the maximum performance level taken for computing the arch_max_freq_ratio value used in the x86 scale-invariance code is higher than the one corresponding to the cpuinfo.max_freq value coming from the acpi_cpufreq driver, the scale-invariant utilization falls below 100% even if the CPU runs at cpuinfo.max_freq or slightly faster, which causes the schedutil governor to select a frequency below cpuinfo.max_freq. That frequency corresponds to a frequency table entry below the maximum performance level necessary to get to the "boost" range of CPU frequencies which prevents "boost" frequencies from being used in some workloads. While this issue is related to scale-invariance, it may be amplified by commit db865272d9c4 ("cpufreq: Avoid configuring old governors as default with intel_pstate") from the 5.10 development cycle which made it extremely easy to default to schedutil even if the preferred driver is acpi_cpufreq as long as intel_pstate is built too, because the mere presence of the latter effectively removes the ondemand governor from the defaults. Distro kernels are likely to include both intel_pstate and acpi_cpufreq on x86, so their users who cannot use intel_pstate or choose to use acpi_cpufreq may easily be affectecd by this issue. If CPPC is available, it can be used to address this issue by extending the frequency tables created by acpi_cpufreq to cover the entire available frequency range (including "boost" frequencies) for each CPU, but if CPPC is not there, acpi_cpufreq has no idea what the maximum "boost" frequency is and the frequency tables created by it cannot be extended in a meaningful way, so in that case make it ask the arch scale-invariance code to to use the "nominal" performance level for CPU utilization scaling in order to avoid the issue at hand.

2021-02-08cpufreq: ACPI: Extend frequency tables to cover boost frequenciesRafael J. Wysocki
A severe performance regression on AMD EPYC processors when using the schedutil scaling governor was discovered by Phoronix.com and attributed to the following commits: 41ea667227ba ("x86, sched: Calculate frequency invariance for AMD systems") 976df7e5730e ("x86, sched: Use midpoint of max_boost and max_P for frequency invariance on AMD EPYC") The source of the problem is that the maximum performance level taken for computing the arch_max_freq_ratio value used in the x86 scale- invariance code is higher than the one corresponding to the cpuinfo.max_freq value coming from the acpi_cpufreq driver. This effectively causes the scale-invariant utilization to fall below 100% even if the CPU runs at cpuinfo.max_freq or slightly faster, so the schedutil governor selects a frequency below cpuinfo.max_freq then. That frequency corresponds to a frequency table entry below the maximum performance level necessary to get to the "boost" range of CPU frequencies. However, if the cpuinfo.max_freq value coming from acpi_cpufreq was higher, the schedutil governor would select higher frequencies which in turn would allow acpi_cpufreq to set more adequate performance levels and to get to the "boost" range of CPU frequencies more often. This issue affects any systems where acpi_cpufreq is used and the "boost" (or "turbo") frequencies are enabled, not just AMD EPYC. Moreover, commit db865272d9c4 ("cpufreq: Avoid configuring old governors as default with intel_pstate") from the 5.10 development cycle made it extremely easy to default to schedutil even if the preferred driver is acpi_cpufreq as long as intel_pstate is built too, because the mere presence of the latter effectively removes the ondemand governor from the defaults. Distro kernels are likely to include both intel_pstate and acpi_cpufreq on x86, so their users who cannot use intel_pstate or choose to use acpi_cpufreq may easily be affectecd by this issue. To address this issue, extend the frequency table constructed by acpi_cpufreq for each CPU to cover the entire range of available frequencies (including the "boost" ones) if CPPC is available and indicates that "boost" (or "turbo") frequencies are enabled. That causes cpuinfo.max_freq to become the maximum "boost" frequency of the given CPU (instead of the maximum frequency returned by the ACPI _PSS object that corresponds to the "nominal" performance level).

This reverts commit 842067940a3e3fc008a60fee388e000219b32632. For some solutions e.g. sound/soc/intel/catpt, DW DMA is part of a compound device (in that very example, domains: ADSP, SSP0, SSP1, DMA0 and DMA1 are part of a single entity) rather than being a standalone one. Driver for said device may enlist DMA to transfer data during suspend or resume sequences. Manipulating RPM explicitly in dw's DMA request and release channel functions causes suspend() to also invoke resume() for the exact same device. Similar situation occurs for resume() sequence. Effectively renders device dysfunctional after first suspend() attempt. Revert the change to address the problem.

2021-02-06net: ipa: do not cache event ring stateAlex Elder
An event ring's state only needs to be known when it is allocated, reset, or deallocated. We check an event ring's state both before and after performing an event ring control command that changes its state. These are only issued at startup and shutdown, so there is very little value in caching the state. Stop recording a copy of the channel's last known state, and instead fetch the true state from hardware whenever it's needed. In such cases, *do* record the state in a local variable, in case an error message reports it (so the value reported is the value seen).

2021-02-06net: dsa: felix: propagate the LAG offload ops towards the ocelot libVladimir Oltean
The ocelot switch has been supporting LAG offload since its initial commit, however felix could not make use of that, due to lack of a LAG abstraction in DSA. Now that we have that, let's forward DSA's calls towards the ocelot library, who will deal with setting up the bonding.

2021-02-06net: mscc: ocelot: rebalance LAGs on link up/down eventsVladimir Oltean
At present there is an issue when ocelot is offloading a bonding interface, but one of the links of the physical ports goes down. Traffic keeps being hashed towards that destination, and of course gets dropped on egress. Monitor the netdev notifier events emitted by the bonding driver for changes in the physical state of lower interfaces, to determine which ports are active and which ones are no longer. Then extend ocelot_get_bond_mask to return either the configured bonding interfaces, or the active ones, depending on a boolean argument. The code that does rebalancing only needs to do so among the active ports, whereas the bridge forwarding mask and the logical port IDs still need to look at the permanently bonded ports.

2021-02-06net: mscc: ocelot: drop the use of the "lags" arrayVladimir Oltean
We can now simplify the implementation by always using ocelot_get_bond_mask to look up the other ports that are offloading the same bonding interface as us. In ocelot_set_aggr_pgids, the code had a way to uniquely iterate through LAGs. We need to achieve the same behavior by marking each LAG as visited, which we do now by using a temporary 32-bit "visited" bitmask. This is ok and we do not need dynamic memory allocation, because we know that this switch architecture will not have more than 32 ports (the PGID port masks are 32-bit anyway).

2021-02-06net: mscc: ocelot: set up logical port IDs centrallyVladimir Oltean
The setup of logical port IDs is done in two places: from the inconclusively named ocelot_setup_lag and from ocelot_port_lag_leave, a function that also calls ocelot_setup_lag (which apparently does an incomplete setup of the LAG). To improve this situation, we can rename ocelot_setup_lag into ocelot_setup_logical_port_ids, and drop the "lag" argument. It will now set up the logical port IDs of all switch ports, which may be just slightly more inefficient but more maintainable.

2021-02-06net: mscc: ocelot: avoid unneeded "lp" variable in LAG joinVladimir Oltean
The index of the LAG is equal to the logical port ID that all the physical port members have, which is further equal to the index of the first physical port that is a member of the LAG. The code gets a bit carried away with logic like this: if (a == b) c = a; else c = b; which can be simplified, of course, into: c = b; (with a being port, b being lp, c being lag) This further makes the "lp" variable redundant, since we can use "lag" everywhere where "lp" (logical port) was used. So instead of a "c = b" assignment, we can do a complete deletion of b. Only one comment here: if (bond_mask) { lp = __ffs(bond_mask); ocelot->lags[lp] = 0; } lp was clobbered before, because it was used as a temporary variable to hold the new smallest port ID from the bond. Now that we don't have "lp" any longer, we'll just avoid the temporary variable and zeroize the bonding mask directly.

2021-02-06net: mscc: ocelot: set up the bonding mask in a way that avoids a net_deviceVladimir Oltean
Since this code should be called from pure switchdev as well as from DSA, we must find a way to determine the bonding mask not by looking directly at the net_device lowers of the bonding interface, since those could have different private structures. We keep a pointer to the bonding upper interface, if present, in struct ocelot_port. Then the bonding mask becomes the bitwise OR of all ports that have the same bonding upper interface. This adds a duplication of functionality with the current "lags" array, but the duplication will be short-lived, since further patches will remove the latter completely.

Recommended value is 1. ANA::AGGR_CFG.AC_IP6_FLOW_LBL_ENA Use IPv6 flow label when calculating AC. Configure identically for all ports. Recommended value is 1.
