The thunderx ethernet driver fails to build on architectures that do not have an atomic readq() and writeq() function for 64-bit PCI bus access: drivers/net/ethernet/cavium/thunder/thunder_bgx.c: In function 'bgx_reg_read': include/asm-generic/io.h:195:23: error: implicit declaration of function 'readq' [-Werror=implicit-function-declaration] It seems impossible to get this driver to work on most 32-bit hardware, so it's better to add an explicit dependency, in order to let us keep building 'allmodconfig' kernels on all architectures. As the driver is meant for the internal hardware on an arm64 SoC, this is not a problem for usability. Allowing the build on all 64-bit architectures rather than just CONFIG_ARM64 on the other hand means that we get the benefit of build testing on x86. Signed-off-by:

When freeing a CQ, we need to make sure there are no asynchronous events (on the ASYNC EQ) that could relate to this CQ before freeing it. This is done by introducing synchronize_irq. Signed-off-by:

Now that EQs management is in the sole responsibility of mlx4_core, the IRQ affinity hints configuration should be in its hands as well. request_irq is called only once by the first consumer (maybe mlx4_ib), so mlx4_en passes the affinity mask too late. We also need to request vectors according to the cores we want to run on. mlx4_core distribution of IRQs to cores is straight forward, EQ(i)->IRQ will set affinity hint to core i. Consumers need to request EQ vectors, according to their cores considerations (NUMA). Signed-off-by:

Matan Barak authored
Previously, mlx4_en allocated EQs and used them exclusively. This affected RoCE performance, as applications which are events sensitive were limited to use only the legacy EQs. Change that by introducing an EQ pool. This pool is managed by mlx4_core. EQs are assigned to ports (when there are limited number of EQs, multiple ports could be assigned to the same EQs). An exception to this rule is the ASYNC EQ which handles various events. Legacy EQs are completely removed as all EQs could be shared. When a consumer (mlx4_ib/mlx4_en) requests an EQ, it asks for EQ serving on a specific port. The core driver calculates which EQ should be assigned to that request. Because IRQs are shared between IB and Ethernet modules, their names only include the PCI device BDF address. Signed-off-by:

In SRIOV, when simple (i.e - Ethernet L2 only) flow steering rules are created, always create them at MLX4_DOMAIN_NIC priority (instead of the real priority the function created them at).

Amir Vadai says: ==================== net/mlx5: ConnectX-4 100G Ethernet driver This patchset extends the mlx5_core driver to support Ethernet functionality. The Ethernet functionality in the mlx5 driver is integrated into the core driver and not as separated driver. The IB functionality remains in the mlx5_ib driver as before. This functionality will enable the Ethernet capability of Mellanox's new famility of cards - ConnectX-4. Due to the fact that backword compatability is being kept, existing Connect-IB cards that are using this driver are fully working with the modified driver, and no issues with current deployments should be seen. Like the ConnectX-3 cards, ConnectX-4 is a VPI (Virtual Port Interface - every port can be configured as Infiniband or Ethernet) card. Unlike previous generations, the ConnectX-4 has a separate PCI function per port. The current code has a limitation that Infiniband and Ethernet port types are mutually exclusive. When the driver is compiled with Ethernet support, the Infiniband functionality is disabled and vice versa. To control that we added the CONFIG_MLX5_CORE_EN config directive which is 'n' by default, but can be changed by the user. This limitation is short-lived and would be addressed soon. As part of this patchset, mlx5_ifc.h was heavily modified [1]. This file is now generated automatically from the device specification document. Since this patch is too big for the mail server, it might be missing in the mailing list, but could be pulled from an external git repository [2]. irq name selection is done at driver initialization and doesn't contain the interface name as part of the irq name. irq_balancer will still work thanks to an improvement introduced by Neil Horman [3] to use sysfs instead of /proc/interrupts. Patchset was applied on top of commit ed2dfd90 ("tcp/dccp: warn user for preferred ip_local_port_range") [1] - Patch 4/11 ("net/mlx5_core: HW data structs/types definitions preparation for mlx5 ehternet driver") [2] - http://git.openfabrics.org/?p=~amirv/linux.git;a=shortlog;h=refs/heads/mlx5e_v1 [3] - kernel: da8d1c8b PCI/sysfs: add per pci device msi[x] irq listing (v5) irq_balancer: 32a7757 Complete rework of how we detect and classify irqs Thanks to Achiad, Saeed, Yevheny, Or and the whole team for making this happen, Amir Changes from V4: - Removed Patch 3/12: net/mlx5_core: Add EQ renaming mechanism - Patch 12/12: net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionality - irq name is created on driver initialization, therefore it won't contain the network interface name in it. This won't effect irq_balancer thanks to patches introduced by Neil Horman to use sysfs instead of /proc/interrupts. Changes from V3: - PATCH 8/11: net/mlx5_core: Set/Query port MTU commands - Return value directly - no need for err. Changes from V2: - Improved changelogs and cover-letter - Added CONFIG_MLX5_EN to disable/enable the Ethernet functionality - Moved en.h and wq.[ch] into the patch with data-path related code Changes from V1: - Added patch 1/12 ("net/mlx5_core,mlx5_ib: Do not use vmap() on coherent memory") Changes from V0: - Removed V0 Patch 1/11 ("net/mlx5_core: Virtually extend work/completion queue buffers by one page") due to misuse of DMA API.

This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver extends the existing mlx5 driver with Ethernet functionality. This patch contains the driver entry points but does not include transmit and receive (see the previous patch in the series) routines. It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the Ethernet functionality. Currently, Kconfig is programmed to make Ethernet and Infiniband functionality mutally exclusive. Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND being selected. Signed-off-by:

en_[rt]x.c contains the data path related code specific to tx or rx. en_txrx.c contains data path code which is common for both the rx and tx, this is mainly napi related code. Below are the objects that are being used by the hardware and the driver in the data path: Channel - one channel per IRQ. Every channel object contains: RQ - describes the rx queue TIR - One TIR (Transport Interface Receive) object per flow type. TIR contains attributes for a type of rx flow (e.g IPv4, IPv6 etc). A flow is defined in the Flow Table. Currently TIR describes the RSS hash parameters if exists and LRO attributes. SQ - describes the a tx queue. There is one SQ (Send Queue) per TC (traffic class). TIS - There is one TIS (Transport Interface Send) per TC. It describes the TC and may later be extended to describe more transport properties. Both RQ and SQ inherit from the object WQ (work queue). This common code to describe the layout of CQE's WQE's in memory is in the files wq.[cj] For every channel there is one NAPI context that is used for RX and for TX. Driver is using netdev_alloc_skb() to allocate skb's. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-05-28 This series contains updates to ethtool, ixgbe, i40e and i40evf. John adds helper routines for ethtool to pass VF to rx_flow_spec. Since the ring_cookie is 64 bits wide which is much larger than what could be used for actual queue index values, provide helper routines to pack a VF index into the cookie. Then John provides a ixgbe patch to allow flow director to use the entire queue space. Neerav provides a i40e patch to collect XOFF Rx stats, where it was not being collected before. Anjali provides ATR support for tunneled packets, as well as stats to count tunnel ATR hits. Cleaned up PF struct members which are unnecessary, since we can use the stat index macro directly. Cleaned up flow director ATR/SB messages to a higher debug level since they are not useful unless silicon validation is happening. Greg provides a patch to disable offline diagnostics if VFs are enabled since ethtool offline diagnostic tests are not designed (out of scope) to disable VF functions for testing and re-enable afterward. Also cleans up TODO comment that is no longer needed. Vasu provides a fix an FCoE EOF case where i40e_fcoe_ctxt_eof() maybe called before i40e_fcoe_eof_is_supported() is called. Jesse adds skb->xmit_more support for i40evf. Then provides a performance enhancement for i40evf by inlining some functions which provides a 15% gain in small packet performance. Also cleans up the use of time_stamp since it is no longer used to determine if there is a tx_hang and was a part of a previous tx_hang design which is no longer used. ==================== Signed-off-by:

The current algorithm for deciding on the number of VRSS channels is not optimal since we open up the min of number of CPUs online and the number of VRSS channels the host is offering. So on a 32 VCPU guest we could potentially open 32 VRSS subchannels. Experimentation has shown that it is best to limit the number of VRSS channels to the number of CPUs within a NUMA node. Here is the new algorithm for deciding on the number of sub-channels we would open up: 1) Pick the minimum of what the host is offering and what the driver in the guest is specifying as the default value. 2) Pick the minimum of (1) and the numbers of CPUs in the NUMA node the primary channel is bound to.

These are not useful unless SV is happening as there is a FD flush counter that tracks this. Change-ID: If2655b5a29687247d03a51d35f69854bbeb711ce Signed-off-by:

Because i40e_fcoe_ctxt_eof should never be called without i40e_fcoe_eof_is_supported being called first, the EOF in fcoe_ctxt_eof should always be valid and therefore we do not need to print an error if it is not valid. However, a WARN ON to easily catch any calls to i40e_fcoe_ctxt_eof that aren't preceded with a call to i40e_fcoe_eof_is_supported is helpful.
