* Update page fault event according to last specification. * Separate code path for page fault EQ, completion EQ and async EQ. * Move page fault handling work queue from mlx5_ib static variable into mlx5_core page fault EQ. * Allocate memory to store ODP event dynamically as the events arrive, since in atomic context - use mempool. * Make mlx5_ib page fault handler run in process context.

Update PAGE_FAULT_RESUME command layout. Three bit fields describing page fault: rdma, rdma_write, req_res gave 8 possible combinations, while only a few were legal. Now they are interpreted as three-bit type field, where former legal combinations turns into corresponding types and unused were added as new types. Signed-off-by:

In this change we turn mlx5_ib_update_mtt() into generic mlx5_ib_update_xlt() to perfrom HCA translation table modifiactions supporting both atomic and process contexts and not limited by number of modified entries. Using this function we increase preallocated MRs up to 16GB. Signed-off-by:

* Update struct mlx5_wqe_umr_ctrl_seg. * Currenlty UMR send_flags aim only certain use cases: enabled/disable cached MR, modifying XLT for ODP. By making flags independent make UMR more flexible allowing arbitrary manipulations. * Since different UMR formats have different entry sizes UMR request should receive exact size of translation table update instead of number of entries. Rename field npages to xlt_size in struct mlx5_umr_wr and update relevant code accordingly. * Add support of length64 bit. Signed-off-by:

This patch adds the following items to IFC file. 1. MLX5_MKC_ACCESS_MODE_KSM enum value for creating KSM memory keys. KSM access mode used when indirect MKey associated with fixed memory size entries. 2. null_mkey field that is used to indicate non-present KLM/KSM entries, where it causes the device to generate page fault event when trying to access it. 3. struct mlx5_ifc_cmd_hca_cap_bits capability bits indicating related value/field is supported: * fixed_buffer_size - MLX5_MKC_ACCESS_MODE_KSM * umr_extended_translation_offset - translation_offset_42_16 in UMR ctrl segment * null_mkey - null_mkey in QUERY_SPECIAL_CONTEXTS Signed-off-by: -

Clean up the following common code (to post a list of work requests to the send queue of the specified QP) at various places and add a helper function 'mlx5_ib_post_send_wait' to implement the same. - Initialize 'mlx5_ib_umr_context' on stack - Assign "mlx5_umr_wr:wr:wr_cqe to umr_context.cqe - Acquire the semaphore - call ib_post_send with a single ib_send_wr - wait_for_completion() - Check for umr_context.status - Release the semaphore Signed-off-by:

The order of features exposed by private mlx5-abi.h file is CQE zipping, packet pacing and multi-packet WQE. The internal order implemented in mlx5_ib_query_device() is multi-packet WQE, CQE zipping and packet pacing. Such difference hurts code readability, so let's sync, while mlx5-abi.h (exposed to userspace) is the primary order. This commit doesn't change any functionality. Signed-off-by:

Merge tag 'wireless-drivers-next-for-davem-2017-01-02' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for 4.11 The most notable change here is the inclusion of airtime fairness scheduling to ath9k. It prevents slow clients from hogging all the airtime and unfairly slowing down faster clients. Otherwise smaller changes and cleanup. Major changes: ath9k * cleanup eeprom endian handling * add airtime fairness scheduling ath10k * fix issues for new QCA9377 firmware version * support dev_coredump() for firmware crash dump * enable channel 169 on 5 GHz band ==================== Signed-off-by:

For core revision 3.x Address-Aligned Beats is available in two registers. The DT property snps,aal was created for AAL in the DMA bus register, which is a read/write bit. The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode register, which is a read only bit that reflects the value of AAL in the DMA bus register. Since the value of snps,axi_all is never used in the driver, and since the property was created for a bit that is read only, it should be safe to remove the property. Acked-by:

Yuval Mintz says: ==================== qed*: Driver updates The more interesting changes in this series include: - Restructuring of the qede files - qede_main.c has grown big and this series splits it into 3 parts [patches #2 and #3]. - Some significant changes in the API through which RSS indirection table gets configured [#8]. - Support for ndo_set_vf_trust() [#9] which would regulate which VFs are allowed to use promisc/multi-promisc mode. It also contains various minor changes to qed/qede, as well as non-functional changes [#1, #12] to complement other changes. ==================== Signed-off-by: -

During Rx flow driver allocates a replacement buffer each time it consumes an Rx buffer. Failing to do so, it would consume the currently processed buffer and re-post it on the ring. As a result, the Rx ring is always completely full [from driver POV]. We now allow the Rx ring to shorten by doing the re-allocations at the end of the NAPI run. The only limitation is that we still want to make sure each time we reallocate that we'd still have sufficient elements in the Rx ring to guarantee that FW would be able to post additional data and trigger an interrupt.

Today qede requests contexts that would suffice for 64 'whole' combined queues [192 meant for 64 rx, tx and xdp tx queues], but registers netdev and limits the number of queues based on information received by qed. In turn, qed doesn't take context into account when informing qede how many queues it can support. This would lead to a configuration problem in case user tries configuring >64 combined queues to interface [or >96 in case xdp isn't enabled]. Since we don't have a mangement firware that actually provides so many interrupt lines to a single device we're currently safe but that's about to change soon. The new maximum is hence changed: - For RoCE devices, the limit would remain 64. - For non-RoCE devices, the limit might be higher [depending on the actual configuration of the device]. qed would start enforcing that limit in both scenarios.

Since the submission of the qedr driver, there's inconsistency in the licensing of the various qed/qede files - some are GPLv2 and some are dual-license. Since qedr requires dual-license and it's dependent on both, we're updating the licensing of all qed/qede source files. Signed-off-by:

In a few cases the err-variable is not set to a negative error code if a function call in typhoon_init_one() fails and thus 0 is returned instead. It may be better to set err to the appropriate negative error code before returning. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=188841Reported-by:

IP_MULTICAST_IF fails if sk_bound_dev_if is already set and the new index does not match it. e.g., ntpd[15381]: setsockopt IP_MULTICAST_IF 192.168.1.23 fails: Invalid argument Relax the check in setsockopt to allow setting mc_index to an L3 slave if sk_bound_dev_if points to an L3 master. Make a similar change for IPv6. In this case change the device lookup to take the rcu_read_lock avoiding a refcnt. The rcu lock is also needed for the lookup of a potential L3 master device. This really only silences a setsockopt failure since uses of mc_index are secondary to sk_bound_dev_if if it is set. In both cases, if either index is an L3 slave or master, lookups are directed to the same FIB table so relaxing the check at setsockopt time causes no harm. Patch is based on a suggested change by Darwin for a problem noted in their code base. Suggested-by:Darwin Dingel <darwin.dingel@alliedtelesis.co.nz> Signed-off-by:

The addresses of Wlan NIC registers are natural alignment, but some drivers have bugs. These are evident on platforms that need natural alignment to access registers. This change contains the following: 1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI, thus it should use rtl_read_byte(). 2. Register 0x4C7 of 8192ee is single byte.
