* MFC r305360:Dimitry Andric2016-09-071-1/+1
| | | | | | | | | | | | | | | | | | With clang 3.9.0, compiling cxgb results in the following warning: sys/dev/cxgb/cxgb_sge.c:2873:44: error: implicit conversion from 'int' to 'char' changes value from 128 to -128 [-Werror,-Wconstant-conversion] *mtod(m, char *) = CPL_ASYNC_NOTIF; ~ ^~~~~~~~~~~~~~~ This is because CPL_ASYNC_NOTIF is 0x80, so the plain char argument is wrapped to a negative value.

* MFC r276959:Navdeep Parhar2015-01-188-33/+59
| | | | | | | | | | | | | | | | cxgb: replace r273280 with a more comprehensive fix. Poll for link state when the link is down, even for interrupt capable PHYs. Allow PHYs to report a dubious "partial" link. If this state is seen 3 consecutive times (each check is ~1s apart) then reset the PHY. This is a workaround for a situation where repeatedly toggling the link from the peer gets the AEL2005 PHY into a state where it never establishes a PCS block lock even when everything is in order.

Build tested with make universe. r237263: - Updated TOE support in the kernel. ... r237563: Fix clang warning when compiling iw_cxgb. r239511: Correctly handle the case where an inp has already been dropped by the time the TOE driver reports that an active open failed. toe_connect_failed is supposed to handle this but it should be provided the inpcb instead of the tcpcb which may no longer be around. r243603: Make sure that tcp_timer_activate() correctly sees TCP_OFFLOAD (or not). r245915: Heed SO_NO_OFFLOAD. r245916: Teach toe_4tuple_check() to deal with IPv6 4-tuples too. r245919: Add TCP_OFFLOAD hook in syncache_respond for IPv6 too, just like the one that exists for IPv4. r245921: There is no need to call into the TOE driver twice in pru_rcvd (tod_rcvd and then tod_output right after that). r245922: Avoid NULL dereference in nd6_storelladdr when no mbuf is provided. It is called this way from a couple of places in the OFED code. (toecore calls it too but that's going to change shortly). r245924: Move lle_event to if_llatbl.h lle_event replaced arp_update_event after the ARP rewrite and ended up in if_ether.h simply because arp_update_event used to be there too. IPv6 neighbor discovery is going to grow lle_event support and this is a good time to move it to if_llatbl.h. The two in-tree consumers of this event - OFED and toecore - are not affected. r245925: Generate lle_event in the IPv6 neighbor discovery code too. r245932: Teach toe_l2_resolve to resolve IPv6 destinations too. r245934: Add checks for SO_NO_OFFLOAD in a couple of places that I missed earlier in r245915.

Improve other error messages while here. - Select special FPGA specific configuration profile when appropriate. r249382: There is no need for elaborate queries and error checking when trying to set FW4MSG_ENCAP. r249383: Get rid of a couple of stray \n's. r249385: cxgbe/tom: Slight simplification of code that calculates options2. r249391: Auto-reduce the holdoff timers that are greater than the maximum value allowed by the hardware. r249392: Cosmetic change (s/wrwc/wcwr/;s/WRWC/WCWR/). r249393: Add pciids of the T5 based cards. The ones that I haven't tested with cxgbe(4) are disabled for now. This will change. r249627: cxgbe/tom: Update the CLIP table on the chip when there are changes to the list of IPv6 addresses on the system. The table is used for TOE+IPv6 only. r249629: cxgbe(4): Refuse to install T5 firmwares on a T4 card (and vice versa). r250090: cxgbe(4): Some updates to shared code. r250092: - Provide accurate ifmedia information so that 40G ports/transceivers are displayed properly in ifconfig, etc. - Use the same number of tx and rx queues for a 40G port as for a 10G port. r250093: Attach to the T580 (2 x 40G) card. r250117: Fix DDP breakage introduced in r248925. Bitwise OR has higher precedence than ternary conditional. r250218: cxgbe/tom: Do not use M_PROTO1 to mark rx zero-copy mbufs as special. All the M_PROTOn flags are clobbered when an mbuf is appended to the socket buffer. r250221: cxgbe: Switch to a better way to install firmware. r250614: Deal correctly with 40G ports that don't have any transceiver plugged in. Do not claim that they have unknown tranceivers. r251213: cxgbe(4): Some more debug sysctls. These work on both T4 and T5 based cards. r251317: cxgbe(4): t4fw_cfg must be explicitly loaded if the driver is being loaded via loader.conf. r251358: cxgbe(4): Provide accurate hit count for filters on T5 cards. The location within the TCB and the size have both changed. r251434: cxgbe(4): Never install a firmware if hw.cxgbe.fw_install is 0. r251518: cxgbe/tom: Fix bad signed/unsigned mixup in the stid allocator. This fixes a panic when allocating a mixture of IPv6 and IPv4 stids. r251638: cxgbe/tom: Allow caller to select the queue (control or data) used to send the CPL_SET_TCB_FIELD request in t4_set_tcb_field(). r252312: Update T5 register ranges. This is so that regdump skips over registers with read side-effects. r252469: Add a sysctl to get the number of filters available. sysctl dev.t4nex.<N>.nfilters sysctl dev.t5nex.<N>.nfilters r252470: Count the number of hits for a filter by default. r250697: Add dependencies on the firmware, which allows the loading of the cxgb and cxgbe modules.

Note that TCP_OFFLOAD is not enabled in 9 yet and so some of these MFCs don't really affect functionality. But they do help future MFCs (related to TCP_OFFLOAD or not) by minimizing diffs with the driver in head. r245243: cxgbe(4): updates to the configuration file that controls how hardware resources are partitioned. - Reduce the number of virtual interfaces reserved for PF4. This leaves spare room in the source MAC table and allows the driver to setup filters that rewrite the source MAC address. - Reduce the number of filters and use the freed up space for the CLIP (Compressed Local IPv6 addresses) table. This is a prerequisite for IPv6 TOE support which will follow separately in a series of commits. r245274: cxgbe(4): Add functions to help synchronize "slow" operations (those not on the fast data path) and use them instead of frobbing the adapter lock and busy flag directly. Other changes made while reworking all slow operations: - Wait for the reply to a filter request (add/delete). This guarantees that the operation is complete by the time the ioctl returns. - Tidy up the tid_info structure. - Do not allow the tx queue size to be set to something that's not a power of 2. r245276: Overhaul the stid allocator so that it can be used for IPv6 servers too. The entry for an IPv6 server in the TCAM takes up the equivalent of two ordinary stids and must be properly aligned too. r245434: cxgbe(4): Updates to the hardware L2 table management code. - Add full support for IPv6 addresses. - Read the size of the L2 table during attach. Do not assume that PCIe physical function 4 of the card has all of the table to itself. - Use FNV instead of Jenkins to hash L3 addresses and drop the private copy of jhash.h from the driver. r245441: cxgbe/tom: Miscellaneous updates for TOE+IPv6 support (more to follow). - Teach find_best_mtu_idx() to deal with IPv6 endpoints. - Install correct protosw in offloaded TCP/IPv6 sockets when DDP is enabled. - Move set_tcp_ddp_ulp_mode to t4_tom.c so that t4_tom.h can be included without having to drag in t4_msg.h too. This was bothering the iWARP driver for some reason. r245448: cxgbe/tom: Basic CLIP table management. This is the Compressed Local IPv6 table on the chip. To save space, the chip uses an index into this table instead of a full IPv6 address in some of its hardware data structures. For now the driver fills this table with all the local IPv6 addresses that it sees at the time the table is initialized. I'll improve this later so that the table is updated whenever new IPv6 addresses are configured or existing ones deleted. r245467: cxgbe/tom: Add support for fully offloaded TCP/IPv6 connections (active open). r245468: cxgbe/tom: Add support for fully offloaded TCP/IPv6 connections (passive open). r245517: cxgbe: Fix the for_each_foo macros -- the last argument should not share its name with any member of struct sge. r245518: cxgbe: Do a more thorough job in the CLEAR_STATS ioctl. r245520: Allow "ivlan" (inner VLAN) to be used as an alias for "vlan" when specifying match criteria. "vlan" continues to be valid here, and it continues to be valid when deleting, rewriting, inserting, or stacking an 802.1q tag to a matching packet. r245567: cxgbe: Make the for_each macros safer to use by turning them into a single statement each. r245933: cxgbe/tom: List IFCAP_TOE6 as supported now that all the required pieces are in place. You still have to enable it explicitly, after loading the t4_tom KLD. r245935: Add a couple of missing error codes. Treat CPL_ERR_KEEPALV_NEG_ADVICE as negative advice and not a fatal error. r245936: Force the 404-BT card (4 x 1G) to use the "uwire" configuration file. r245937: Install an extra hold on the newly allocated synq entry so that it cannot be freed while do_pass_accept_req is running. This closes a race where do_pass_establish on another CPU (the driver chose a different queue for the new tid) expands the synq entry into a full PCB and then releases the only hold on it, all while do_pass_accept_req is still running. r246093: Provide a statistic to track the number of drops in each of the port's txq's buf_ring. The aggregate for all the queues of a port is already provided in ifnet->if_snd.ifq_drops. r246385: Busy-wait when cold. r246575: Do not hold locks around hardware context reads. r247062: cxgbe(4): Assume that CSUM_TSO in the transmit path implies CSUM_IP and CSUM_TCP too. They are all set explicitly by the kernel usually. r247122: cxgbe(4): Add sysctls to extract debug information from the chip: dev.t4nex.X.misc.cim_la logic analyzer dump dev.t4nex.X.misc.cim_qcfg queue configuration dev.t4nex.X.misc.cim_ibq_xxx inbound queues dev.t4nex.X.misc.cim_obq_xxx outbound queues r247289: cxgbe(4): Update firmware to 1.8.4.0. r247291: cxgbe(4): Ask the card's firmware to pad up tiny CPLs by encapsulating them in a firmware message if it is able to do so. This works out better for one of the FIFOs in the chip. r247347: cxgbe(4): Consider all the API versions of the interfaces exported by the firmware (instead of just the main firmware version) when evaluating firmware compatibility. Document the new "hw.cxgbe.fw_install" knob being introduced here. This should fix kern/173584 too. Setting hw.cxgbe.fw_install=2 will mostly do what was requested in the PR but it's a bit more intelligent in that it won't reinstall the same firmware repeatedly if the knob is left set. r247355: cxgbe(4): Report unusual out of band errors from the firmware. r241733 (by ed@): Prefer __containerof() over __member2struct(). The former works better with qualifiers, but also properly type checks the input pointer. Notes: svn path=/stable/9/; revision=247434

Initialize such freelists with correct values. This wasn't a problem for common MTUs (1500 and 9000) as the buffers (2048 and 9216 in size) happened to have enough spare room. I ran into it when playing around with unusual MTUs. r239336: Allow for a different handler for each type of firmware message. r239338: Add a routine (t4_set_tcb_field) to update arbitrary parts of a hardware TCB. Filters are programmed by modifying the TCB too (via a different routine) and the reply to any TCB update is delivered via a CPL_SET_TCB_RPL. Figure out whether the reply is for a filter-write or something else and route it appropriately. r239339: Make room for DDP page pods in the default configuration profile. While here, bump up the L2 table's size to 4K entries. r239341: Initialize various DDP parameters in the main cxgbe(4) driver: - Setup multiple DDP page sizes. When the driver attempts DDP it will try to combine physically contiguous pages into regions of these sizes. - Set the indicate size such that the payload carried in the indicate can be copied in the header mbuf (and the 16K rx buffer can be recycled). - Set DDP threshold to the max payload that the chip will coalesce and deliver to the driver (this is ~16K by default, which is also why the offload rx queue is backed by 16K buffers). If the chip is able to coalesce up to the max it's allowed to, it's a good sign that the peer is transmitting in bulk without any TCP PSH. r239344: Support for TCP DDP (Direct Data Placement) in the T4 TOE module. Basically, this is automatic rx zero copy when feasible. TCP payload is DMA'd directly into the userspace buffer described by the uio submitted in soreceive by an application. - Works with sockets that are being handled by the TCP offload engine of a T4 chip (you need t4_tom.ko module loaded after cxgbe, and an "ifconfig +toe" on the cxgbe interface). - Does not require any modification to the application. - Not enabled by default. Use hw.t4nex.<X>.toe.ddp="1" to enable it. r239514: Minor cleanup: use bitwise ops instead of pointless wrappers around setbit/clrbit. r239527: Cannot hold a mutex around vm_fault_quick_hold_pages, so don't. Tweak some comments while here. r239528: Avoid a NULL pointer dereference. r239544: Deal with the case where a syncache entry added by the TOE driver is evicted from the syncache but a later syncache_expand succeeds because of syncookies. The TOE driver has to resort to more direct means to install its hooks in the socket in this case. Notes: svn path=/stable/9/; revision=240169

| | | | | | | | | | | | | | | | | | | | | | | | r231317 Add IPv6 TSO (including TSO+VLAN) support to cxgb(4). r235963 (bz@) Allow LRO to work on IPv6 as well. Fix the module Makefile to at least properly inlcude opt_inet6.h and allow builds without INET or INET6. r234831 Make sure that the firmware version is available in dev.t4nex.X.firmware_version even if the driver fails to attach properly. At least it'll be easy to tell what we're dealing with. r234833: Change the default to not use packet counters to generate rx interrupts. Rely solely on the timer based mechanism.
