2018-10-06Merge branch 'mscc-ocelot-add-support-for-SerDes-muxing-configuration'David S. Miller17-180/+559
Quentin Schulz says: ==================== mscc: ocelot: add support for SerDes muxing configuration The Ocelot switch has currently an hardcoded SerDes muxing that suits only a particular use case. Any other board setup will fail to work. To prepare for upcoming boards' support that do not have the same muxing, create a PHY driver that will handle all possible cases. A SerDes can work in SGMII, QSGMII or PCIe and is also muxed to use a given port depending on the selected mode or board design. The SerDes configuration is in the middle of an address space (HSIO) that is used to configure some parts in the MAC controller driver, that is why we need to use a syscon so that we can write to the same address space from different drivers safely using regmap. This breaks backward compatibility but it's fine because there's only one board at the moment that is using what's modified in this patch series. This will break git bisect. Even though this patch series is about SerDes __muxing__ configuration, the DT node is named serdes for the simple reason that I couldn't find any mention to SerDes anywhere else from the address space handled by this driver. v4: - add reviewed-by, - format the patch series with -M for identifying renamed files, - add parent info in DT binding of the SerDes IP, - move to macros SERDES[16]G(X) instead of multiple SERDES[16]G_[012345] constants, - move to SERDES[16]G_MAX being the last VALID macro of a type, so migrate to <= conditions instead of < when iterating, - create a SERDES_MUX_SGMII and SERDES_MUX_QSGMII macro so the muxing configurations are a tad more readable, - use a bunch of unsigned int instead of int, - return -EOPNOTSUPP for SERDES6G/PCIe until it's supported, - simplify condition when there is an error code returned by devm_of_phy_get, v3: - add Paul Burton's Acked-By on MIPS patches so that the patch series can be merged in the net tree in its entirety, v2: - use a switch case for setting the phy_mode in the SerDes driver as suggested by Andrew, - stop replacing the value of the error pointer in the SerDes driver, - use a dev_dbg for the deferring of the probe in the SerDes driver, - use constants in the Device Tree to select the SerDes macro in use with a port, - adapt the SerDes driver to use those constants, - add a header file in include/dt-bindings for the constants, - fix space/tab issue, ==================== Signed-off-by: David S.

2018-10-06net: mscc: ocelot: make use of SerDes PHYs for handling their configurationQuentin Schulz5-12/+63
Previously, the SerDes muxing was hardcoded to a given mode in the MAC controller driver. Now, the SerDes muxing is configured within the Device Tree and is enforced in the MAC controller driver so we can have a lot of different SerDes configurations. Make use of the SerDes PHYs in the MAC controller to set up the SerDes according to the SerDes<->switch port mapping and the communication mode with the Ethernet PHY.

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.

2018-10-04tc: Add support for configuring the taprio schedulerVinicius Costa Gomes4-0/+1020
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.

2018-10-04bnxt_en: Use ignore_ari devlink parameterVasundhara Volam2-0/+7
This patch adds support for ignore_ari generic permanent mode devlink parameter. This parameter is disabled by default. It can be enabled using devlink param commands. ignore_ari - If enabled, device ignores ARI(Alternate Routing ID) capability, even when platforms has the support and creates same number of partitions when platform does not support ARI capability.

msix_vec_per_pf_min - This param sets the number of minimal MSIX vectors required for the device initialization. This value is set in the device which limits MSIX vectors per PF.

2018-10-04qed: Avoid implicit enum conversion in qed_ooo_submit_tx_buffersNathan Chancellor1-1/+12
Clang warns when one enumerated type is implicitly converted to another. drivers/net/ethernet/qlogic/qed/qed_ll2.c:799:32: warning: implicit conversion from enumeration type 'enum core_tx_dest' to different enumeration type 'enum qed_ll2_tx_dest' [-Wenum-conversion] tx_pkt.tx_dest = p_ll2_conn->tx_dest; ~ ~~~~~~~~~~~~^~~~~~~ 1 warning generated. Fix this by using a switch statement to convert between the enumerated values since they are not 1 to 1, which matches how the rest of the driver handles this conversion.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2018-10-03 mlx5 core driver and ethernet netdev updates, please note there is a small devlink releated update to allow extack argument to eswitch operations. From Eli Britstein, 1) devlink: Add extack argument to the eswitch related operations 2) net/mlx5e: E-Switch, return extack messages for failures in the e-switch devlink callbacks 3) net/mlx5e: Add extack messages for TC offload failures From Eran Ben Elisha, 4) mlx5e: Add counter for aRFS rule insertion failures From Feras Daoud 5) Fast teardown support for mlx5 device This change introduces the enhanced version of the "Force teardown" that allows SW to perform teardown in a faster way without the need to reclaim all the FW pages. Fast teardown provides the following advantages: 1- Fix a FW race condition that could cause command timeout 2- Avoid moving to polling mode 3- Close the vport to prevent PCI ACK to be sent without been scatter to memory ==================== Signed-off-by: David S.
