* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2715-1/+15
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* cxgb: replace r273280 with a more comprehensive fix.Navdeep Parhar2015-01-117-32/+57
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon.

| | | | | | | | | | | | | | | | | | | Changes since 7.8.0 (from the official changelog): - Fixed sporadic interrupt generation for associated CQ when processing a local invalidate work request - Changes to core scheduling to avoid starving requests from the host under heavy RDMA Read Request load (e.g. packets to the wire) - Programmed the tp tx resource limiter in function of the traffic (only affects iWarp) - Increased the egress NIC gather list length from 36 to 46 entries MFC after: 1 week Notes: svn path=/head/; revision=220009

* Improve cxgb(4)'s behaviour when faced with temporarily "bouncy" links:Navdeep Parhar2010-07-093-13/+13
| | | | | | | | | | | | | | | | | - Run the adapter's tick at 1Hz and remove link state checks from it. Instead, have each port check its link state. Delay the check so that it takes place slightly after the driver is notified of a change in link state. This is a cheap way to debounce these notifications if many are received in rapid succession. POLL_LINK_1ST_TIME flag can also be eliminated as a side effect of these changes. - Do not reset the PHY when link goes down. - Clear port's link_fault flag if the PHY indicates link is down. - get_link_status_r should leave speed and duplex alone when link is down.

* Multiple fixes related to queue set sizing and resources:Navdeep Parhar2010-03-312-2/+3
| | | | | | | | | | | | | | | | | | | - Only the tunnelq (TXQ_ETH) requires a buf_ring, an ifq, and the watchdog/timer callouts. Do not allocate these for the other tx queues. - Use 16k jumbo clusters only on offload capable cards by default. - Do not allocate a full tx ring for the offload queue if the card is not offload capable. - Slightly better freelist size calculation. - Fix nmbjumbo4 typo, remove unneeded global variables.

* Greatly simplify cxgb by removing almost all of the custom mbuf management logicKip Macy2009-06-191-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - remove mbuf iovec - useful, but adds too much complexity when isolated to the driver - remove driver private caching - insufficient benefit over UMA to justify the added complexity and maintenance overhead - remove separate logic for managing multiple transmit queues, with the new drbr routines the control flow can be made to much more closely resemble legacy drivers - remove dedicated service threads, with per-cpu callouts one can get the same benefit much more simply by registering a callout 1 tick in the future if there are still buffered packets - remove embedded mbuf usage - Jeffr's changes will (I hope) soon be integrated greatly reducing the overhead of using kernel APIs for reference counting clusters - add hysteresis to descriptor coalescing logic - add coalesce threshold sysctls to allow users to decide at run-time between optimizing for forwarding / UDP or optimizing for TCP - add once per second watchdog to effectively close the very rare races occurring from coalescing - incorporate Navdeep's changes to the initialization path required to convert port and adapter locks back to ordinary mutexes (silencing BPF LOR complaints) - enable prefetches in get_packet and tx cleaning Reviewed by: navdeep@ MFC after: 2 weeks Notes: svn path=/head/; revision=194521

* Several small additions to the Chelsio 10G driver.George V. Neville-Neil2008-11-213-2/+19
| | | | | | | | | | | | | | | | 1) Fix a bug in dealing with the Alerus 1006 PHY which prevented the device from ever coming back up once it had been set to down. 2) Add a kernel tunable (hw.cxgb.snd_queue_len) which makes it possible to give the device more than IFQ_MAXLEN entries in its send queue. The default remains 50. 3) Add code to place the card'd identification and serial number into its description (%desc) so that users can tell which card they have installed.
