| | | | | | | | | | | | | | | | | | | Add new mlx5ib(4) driver to the kernel source tree which supports Remote DMA over Converged Ethernet, RoCE, for the ConnectX-4 series of PCI express network cards. There is currently no user-space support and this driver only supports kernel side non-routable RoCE V1. The krping kernel module can be used to test this driver. Full user-space support including RoCE V2 will be added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel module will only be built when WITH_OFED=YES is specified. Approved by: re (marius) Sponsored by: Mellanox Technologies Notes: svn path=/stable/10/; revision=323223

| | | | | | | | | | | | | | | | | 1. Move Rx Processing to fp_taskqueue(). With this CPU utilization for processing interrupts drops to around 1% for 100G and under 1% for other speeds. 2. Use sysctls for TRACE_LRO_CNT and TRACE_TSO_PKT_LEN 3. remove unused mtx tx_lock 4. bind taskqueue kernel thread to the appropriate cpu core 5. when tx_ring is full, stop further transmits till at least 1/16th of the Tx Ring is empty. In our case 1K entries. Also if there are rx_pkts to process, put the taskqueue thread to sleep for 100ms, before enabling interrupts. 6. Use rx_pkt_threshold of 128.

| | | | | | | | | | | | | | | | | | | | | | | | | hyperv/vmbus: Reorganize vmbus device tree For GEN1 Hyper-V, vmbus is attached to pcib0, which contains the resources for PCI passthrough and SR-IOV. There is no acpi_syscontainer0 on GEN1 Hyper-V. For GEN2 Hyper-V, vmbus is attached to acpi_syscontainer0, which contains the resources for PCI passthrough and SR-IOV. There is no pcib0 on GEN2 Hyper-V. The ACPI VMBUS device now only holds its _CRS, which is empty as of this commit; its existence is mainly for upward compatibility.

Besides the user data area, i. e. the default partition, eMMC v4.41 and later devices can additionally provide up to: 1 enhanced user data area partition 2 boot partitions 1 RPMB (Replay Protected Memory Block) partition 4 general purpose partitions (optionally with a enhanced or extended attribute) Besides simply subdividing eMMC devices, some Intel NUCs having UEFI code in the boot partitions etc., another use case for the partition support is the activation of pseudo-SLC mode, which manufacturers of eMMC chips typically associate with the enhanced user data area and/ or the enhanced attribute of general purpose partitions. CAVEAT EMPTOR: Partitioning eMMC devices is a one-time operation. o Now that properly issuing CMD6 is crucial (so data isn't written to the wrong partition for example), make a step into the direction of correctly handling the timeout for these commands in the MMC layer. Also, do a SEND_STATUS when CMD6 is invoked with an R1B response as recommended by relevant specifications. o Add an IOCTL interface to mmcsd(4); this is sufficiently compatible with Linux so that the GNU mmc-utils can be ported to and used with FreeBSD (note that due to the remaining deficiencies outlined above SANITIZE operations issued by/with `mmc` currently most likely will fail). These latter have been added to ports as sysutils/mmc-utils. Among others, the `mmc` tool of mmc-utils allows for partitioning eMMC devices (tested working). o For devices following the eMMC specification v4.41 or later, year 0 is 2013 rather than 1997; so correct this for assembling the device ID string properly. o Let mmcsd.ko depend on mmc.ko. Additionally, bump MMC_VERSION as at least for some of the above a matching pair is required. Notes: svn path=/stable/10/; revision=318198

Unlike virtual machine snapshot, it only takes snapshot for the virtual disks, so both filesystem and applications have to aware of it, and cooperate the whole VSS process. This driver exposes two device files to the userland: /dev/hv_fsvss_dev Normally userland programs should _not_ mess with this device file. It is currently used by the hv_vss_daemon(8), which freezes and thaws the filesystem. NOTE: currently only UFS is supported, if the system mounts _any_ other filesystems, the hv_vss_daemon(8) will veto the VSS process. If hv_vss_daemon(8) was disabled, then this device file must be opened, and proper ioctls must be issued to keep the VSS working. /dev/hv_appvss_dev Userland application can opened this device file to receive the VSS freeze notification, hold the VSS for a while (mainly to flush application data to filesystem), release the VSS process, and receive the VSS thaw notification i.e. applications can run again. The VSS will still work, even if this device file is not opened. However, only filesystem consistency is promised, if this device file is not opened or is not operated properly. hv_vss_daemon(8) is started by devd(8) by default. It can be disabled by editting /etc/devd/hyperv.conf.

| | | | | | | | | | | | | | For whatever reason, smapi, smbios, vpd are all under the "bios" directory. smapi is only for i386, so the entire "bios" directory is only built for i386. Break smapi out, and make only it i386-specific. Then, build the "bios" directory for both amd64 and i386.

VF devices use a different register layout than PF devices. Storing the offset in a value in the softc allows code to be shared between the PF and VF drivers. 303860: Reserve an adapter flag IS_VF to mark VF devices vs PF devices. 303880: Track the base absolute ID of ingress and egress queues. Use this to map an absolute queue ID to a logical queue ID in interrupt handlers. For the regular cxgbe/cxl drivers this should be a no-op as the base absolute ID should be zero. VF devices have a non-zero base absolute ID and require this change. While here, export the absolute ID of egress queues via a sysctl. 304168: Make SGE parameter handling more VF-friendly. Add fields to hold the SGE control register and free list buffer sizes to the sge_params structure. Populate these new fields in t4_init_sge_params() for PF devices and change t4_read_chip_settings() to pull these values out of the params structure instead of reading registers directly. This will permit t4_read_chip_settings() to be reused for VF devices which cannot read SGE registers directly. While here, move the call to t4_init_sge_params() to get_params__post_init(). The VF driver will populate the SGE parameters structure via a different method before calling t4_read_chip_settings(). 304169: Update mailbox writes to work with VF devices. - Use alternate register locations for the data and control registers for VFs. - Do a dummy read to force the writes to the mailbox data registers to post before the write to the control register on VFs. - Do not check the PCI-e firmware register for errors on VFs. 304170: Add support for register dumps on VF devices. - Add handling of VF register sets to t4_get_regs_len() and t4_get_regs(). - While here, use t4_get_regs_len() in the ioctl handler for regdump instead of inlining it. 304479: Add structures for VF-specific adapter parameters. While here, mark which parameters are PF-specific and which are VF-specific. 304482: Adjust t4_port_init() to work with VF devices. Specifically, the FW_PORT_CMD may or may not work for a VF (the PF driver can choose whether or not to permit access to this command), so don't attempt to fetch port information on a VF if permission is denied by the PF. 304485: Reorder sysctls so that nodes shared with the VF driver are added first. This permits a single early return for VF devices in the routines that add sysctl nodes. 305548: Don't break out of the m_advance() loop if len drops to zero. If a packet contains the Ethernet header (14 bytes) in the first mbuf and the payload (IP + UDP + data) in the second mbuf, then the attempt to fetch the l3hdr will return a NULL pointer. The first loop iteration will drop len to zero and exit the loop without setting 'p'. However, the desired data is at the start of the second mbuf, so the correct behavior is to loop around and let the conditional set 'p' to m_data of the next mbuf (and leave offset as 0). 305549: Chelsio T4/T5 VF driver. The cxgbev/cxlv driver supports Virtual Function devices for Chelsio T4 and T4 adapters. The VF devices share most of their code with the existing PF4 driver (cxgbe/cxl) and as such the VF device driver currently depends on the PF4 driver. Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf PCI device driver that attaches to the VF device. It then creates child cxgbev/cxlv devices representing ports assigned to the VF. By default, the PF driver assigns a single port to each VF. t4vf_hw.c contains VF-specific routines from the shared code used to fetch VF-specific parameters from the firmware. t4_vf.c contains the VF-specific PCI device driver and includes its own attach routine. VF devices are required to use a different firmware request when transmitting packets (which in turn requires a different CPL message to encapsulate messages). This alternate firmware request does not permit chaining multiple packets in a single message, so each packet results in a firmware request. In addition, the different CPL message requires more detailed information when enabling hardware checksums, so parse_pkt() on VF devices must examine L2 and L3 headers for all packets (not just TSO packets) for VF devices. Finally, L2 checksums on non-UDP/non-TCP packets do not work reliably (the firmware trashes the IPv4 fragment field), so IPv4 checksums for such packets are calculated in software. Most of the other changes in the non-VF-specific code are to expose various variables and functions private to the PF driver so that they can be used by the VF driver. Note that a limited subset of cxgbetool functions are supported on VF devices including register dumps, scheduler classes, and clearing of statistics. In addition, TOE is not supported on VF devices, only for the PF interfaces. Sponsored by: Chelsio Communications Notes: svn path=/stable/10/; revision=309447

Discrete Device Assignment) The feature enables us to pass through physical PCIe devices to FreeBSD VM running on Hyper-V (Windows Server 2016) to get near-native performance with low CPU utilization. The patch implements a PCI bridge driver to support the feature: 1) The pcib driver talks to the host to discover device(s) and presents the device(s) to FreeBSD's pci driver via PCI configuration space (note: to access the configuration space, we don't use the standard I/O port 0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V, which is very similar to the 0xCF8/CFC method). 2) The pcib driver allocates resources for the device(s) and initialize the related BARs, when the device driver's attach method is invoked; 3) The pcib driver talks to the host to create MSI/MSI-X interrupt remapping between the guest and the host; 4) The pcib driver supports device hot add/remove.

As such, I've trimmed the log message of the first update (1.15.28.0). In addition, the M_WAIT macro added in t4_regs.h had to be renamed to CXGBE_M_WAIT to avoid a collision on 10.x that is not present on 11. 295778: cxgbe: catch up with the latest hardware-related definitions. 296249: cxgbe(4): Update T5 and T4 firmwares to 1.15.28.0. 296333: cxgbe(4): First of many changes to reduce diffs with internal shared code: - Rename some CamelCase variables. - s/t4_link_start/t4_link_l1cfg/g - Pull in t4_get_port_type_description. - Move t4_wait_op_done to t4_hw.c. - Flip the order of the RDMA stats. - Remove unsused function t4_iq_start_stop. - Move t4_wait_op_done and t4_wait_op_done_val to t4_hw.c 296383: cxgbe(4): Very basic T6 awareness. This is part of ongoing work to update to the latest internal shared code. - Add a chip_params structure to keep track of hardware constants for all generations of Terminators handled by cxgbe. - Update t4_hw_pci_read_cfg4 to work with T6. - Update the hardware debug sysctls (hidden within dev.<tNnex>.<n>.misc.*) to work with T6. Most of the changes are in the decoders for the CIM logic analyzer and the MPS TCAM. - Acquire the regwin lock around indirect register accesses. 296471: cxgbe(4): Updated register dumps. - Get the list of registers to read during a regdump from the shared code instead of the OS specific code. This follows a similar move internally. The shared code includes the list for T6. - Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register dumps (and catch up with some updates to T4 and T5 register decode). 296478: cxgbe(4): Add a struct sge_params to store per-adapter SGE parameters.

This fixes a conflict with the M_B macro in powerpc's <machine/db_machdep.h> exposed by the recent addition of DDB commands to the cxgbe driver. 299685: cxgbe(4): Update T5 and T4 firmwares to 1.15.37.0. These firmwares were obtained from the "Chelsio T5/T4 Unified Wire v2.12.0.3 for Linux" release.
