* Use symlinks for kernel modules rather than hardlinksAlan Somers2019-04-201-1/+1
| | | | | | | | | | | | | | When aliasing a kernel module to a different name (ie if_igb for if_em), it's better to use symlinks than hard links. kldxref will omit entries for the links, ensuring that the loaded module has the correct name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | up to 2 rx/tx queues for the 82574. Program the 82574 to enable 5 msix vectors, assign 1 to each rx queue, 1 to each tx queue and 1 to the link handler. Inspired by DragonFlyBSD, enable some RSS logic for handling tx queue handling/processing. Move multiqueue handler functions so that they line up better in a diff review to if_igb.c Always enqueue tx work to be done in em_mq_start, if unable to acquire the TX lock, then this will be processed in the background later by the taskqueue. Remove mbuf argument from em_start_mq_locked() as the work is always enqueued. (stolen from igb) Setup TARC, TXDCTL and RXDCTL registers for better performance and stability in multiqueue and singlequeue implementations. Handle Intel errata 3 and generic multiqueue behavior with the initialization of TARC(0) and TARC(1) Bind interrupt threads to cpus in order. (stolen from igb) Add 2 new DDB functions, one to display the queue(s) and their settings and one to reset the adapter. Primarily used for debugging. In the multiqueue configuration, bump RXD and TXD ring size to max for the adapter (4096). Setup an RDTR of 64 and an RADV of 128 in multiqueue configuration to cut down on the number of interrupts. RADV was arbitrarily set to 2x RDTR and can be adjusted as needed. Cleanup the display in top a bit to make it clearer where the taskqueue threads are running and what they should be doing. Ensure that both queues are processed by em_local_timer() by writing them both to the IMS register to generate soft interrupts. Ensure that an soft interrupt is generated when em_msix_link() is run so that any races between assertion of the link/status interrupt and a rx/tx interrupt are handled. Document existing tuneables: hw.em.eee_setting, hw.em.msix, hw.em.smart_pwr_down, hw.em.sbp Document use of hw.em.num_queues and the new kernel option EM_MULTIQUEUE Thanks to Intel for their continued support of FreeBSD.

* Update to igb and em:Jack F Vogel2010-03-291-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | em revision 7.0.0: - Using driver devclass, seperate legacy (pre-pcie) code into a seperate source file. This will at least help protect against regression issues. It compiles along with em, and is transparent to end use, devices in each appear to be 'emX'. When using em in a modular form this also allows the legacy stuff to be defined out. - Add tx and rx rings as in igb, in the 82574 this becomes actual multiqueue for the first time (2 queues) while in other PCIE adapters its just make code cleaner. - Add RX mbuf handling logic that matches igb, this will eliminate packet drops due to temporary mbuf shortage. igb revision 1.9.3: - Following the ixgbe code, use a new approach in what was called 'get_buf', the routine now has been made independent of rxeof, it now does the update to the engine TDT register, this design allows temporary mbuf resources to become non-critical, not requiring a packet to be discarded, instead it just returns and does not increment the tail pointer. - With the above change it was also unnecessary to keep 'spare' maps around, since we do not have the discard issue. - Performance tweaks and improvements to the code also.

| | | | | | | | | | | | | | | | | | | | | | | | | | | PR 122839 is fixed in both em and in igb Second, the issue on building modules since the static kernel build changes is now resolved. I was not able to get the fancier directory hierarchy working, but this works, both em and igb build as modules now. Third, there is now support in em for two new NICs, Hartwell (or 82574) is a low cost PCIE dual port adapter that has MSIX, for this release it uses 3 vectors only, RX, TX, and LINK. In the next release I will add a second TX and RX queue. Also, there is support here for ICH10, the followon to ICH9. Both of these are early releases, general availability will follow soon. Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support, I have implemented this in a provisional way so that early adopters may try and comment on the functionality. The IOCTL structure may change. This feature is off by default, you need to edit the Makefile and add the EM_TIMESYNC define to get the code. Enjoy all!! Notes: svn path=/head/; revision=178523

Advanced features for virtualization and performance will be in this driver. Also, both drivers now have shared code that is up to the latest we have released. Some stylistic changes as well.
