| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix for mlx4en(4) to properly call m_defrag(). The m_defrag() function can only defrag mbuf chains which have a valid mbuf packet header. In r291699 when the mlx4en(4) driver was converted into using BUSDMA(9), the call to m_defrag() was moved after the part of the transmit routine which strips the header from the mbuf chain. This effectivly disabled the mbuf defrag mechanism and such packets simply got dropped. This patch removes the stripping of mbufs from a chain and loads all mbufs using busdma. If busdma finds there are no segments, unload the DMA map and free the mbuf right away, because that means all data in the mbuf has been inlined in the TX ring. Else proceed as usual. Add a per-ring rounter for the number of defrag attempts and make sure the oversized_packets counter gets zeroed while at it. The counters are per-ring to avoid excessive cache misses in the TX path.

| | | | | | | | | | | | | | | | | | | | | | | | | | mlx4: Use the CQ quota for SRIOV when creating completion EQs When creating EQs to handle CQ completion events for the PF or for VFs, we create enough EQE entries to handle completions for the max number of CQs that can use that EQ. When SRIOV is activated, the max number of CQs a VF (or the PF) can obtain is its CQ quota (determined by the Hypervisor resource tracker). Therefore, when creating an EQ, the number of EQE entries that the VF should request for that EQ is the CQ quota value (and not the total number of CQs available in the firmware). Under SRIOV, the PF, also must use its CQ quota, because the resource tracker also controls how many CQs the PF can obtain. Using the firmware total CQs instead of the CQ quota when creating EQs resulted wasting MTT entries, due to allocating more EQEs than were needed.

| | | | | | | | | | | | | | | | | | | | | | | | | Flexible and asymmetric allocation of EQs and MSI-X vectors for PF/VFs. Previously, the mlx4 driver queried the firmware in order to get the number of supported EQs. Under SRIOV, since this was done before the driver notified the firmware how many VFs it actually needs, the firmware had to take into account a worst case scenario and always allocated four EQs per VF, where one was used for events while the others were used for completions. Now, when the firmware supports the asymmetric allocation scheme, denoted by exposing num_sys_eqs > 0 (--> MLX4_DEV_CAP_FLAG2_SYS_EQS), we use the QUERY_FUNC command to query the firmware before enabling SRIOV. Thus we can get more EQs and MSI-X vectors per function. Moreover, when running in the new firmware/driver mode, the limitation that the number of EQs should be a power of two is lifted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change mlx4 QP allocation scheme. When using Blue-Flame, BF, the QPN overrides the VLAN, CV, and SV fields in the WQE. Thus, BF may only be used for QPNs with bits 6,7 unset. The current ethernet driver code reserves a TX QP range with 256b alignment. This is wrong because if there are more than 64 TX QPs in use, QPNs >= base + 65 will have bits 6/7 set. This problem is not specific for the Ethernet driver, any entity that tries to reserve more than 64 BF-enabled QPs should fail. Also, using ranges is not necessary here and is wasteful. The new mechanism introduced here will support reservation for "Eth QPs eligible for BF" for all drivers: bare-metal, multi-PF, and VFs (when hypervisors support WC in VMs). The flow we use is: 1. In mlx4_en, allocate Tx QPs one by one instead of a range allocation, and request "BF enabled QPs" if BF is supported for the function 2. In the ALLOC_RES FW command, change param1 to: a. param1[23:0] - number of QPs b. param1[31-24] - flags controlling QPs reservation Bit 31 refers to Eth blueflame supported QPs. Those QPs must have bits 6 and 7 unset in order to be used in Ethernet. Bits 24-30 of the flags are currently reserved. When a function tries to allocate a QP, it states the required attributes for this QP. Those attributes are considered "best-effort". If an attribute, such as Ethernet BF enabled QP, is a must-have attribute, the function has to check that attribute is supported before trying to do the allocation. In a lower layer of the code, mlx4_qp_reserve_range masks out the bits which are unsupported. If SRIOV is used, the PF validates those attributes and masks out unsupported attributes as well. In order to notify VFs which attributes are supported, the VF uses QUERY_FUNC_CAP command. This command's mailbox is filled by the PF, which notifies which QP allocation attributes it supports.

| | | | | | | | | | | | | | | | | Initialize vm_page_prot to VM_MEMATTR_DEFAULT instead of 0. If a driver's Linux mmap callback passed vm_page_prot through unchanged, then linux_dev_mmap_single() would try to apply whatever VM_MEMATTR_xxx value 0 is to the mapping. On x86, VM_MEMATTR_DEFAULT is the PAT value for write-back (WB) which is 6, while 0 maps to the PAT value for uncacheable (UC). Thus, any mmap request that did not explicitly set page_prot was tried to map memory as UC triggering the warning in sg_pager_getpages().

| | | | | | | | | | | | | | | | | | Currently the Linux character device mmap handling only supports mmap operations that map a single page that has an associated vm_page_t. This does not permit mapping larger regions (such as a PCI memory BAR) and it does not permit mapping addresses beyond the top of RAM (such as a 64-bit BAR located above the top of RAM). Instead of using a single OBJT_DEVICE object and passing the physaddr via the offset as a hack, create a new sglist and OBJT_SG object for each mmap request.
