| | | | | | | | | | | | | | | 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

* In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson2015-01-061-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.

| | | | | | | | | | | | | | | | | | | | | | | | | | | take advantage of it instead of duplicating it. This reduces the size of the i386 GENERIC kernel by about 4k. The only potential in-tree user left unconverted is xe(4), which generally should be changed to use miibus(4) instead of implementing PHY handling on its own, as otherwise it makes not much sense to add a dependency on miibus(4)/mii_bitbang(4) to xe(4) just for the MII bitbang'ing code. The common MII bitbang'ing code also is useful in the embedded space for using GPIO pins to implement MII access. - Based on lessons learnt with dc(4) (see r185750), add bus barriers to the MII bitbang read and write functions of the other drivers converted in order to ensure the intended ordering. Given that register access via an index register as well as register bank/window switching is subject to the same problem, also add bus barriers to the respective functions of smc(4), tl(4) and xl(4). - Sprinkle some const.

| | | | | | | | | | | | | | | | | | | | | | | | CPU for too long period than necessary. Additively, interfaces are kept polled (in the tick) even if no more packets are available. In order to avoid such situations a new generic mechanism can be implemented in proactive way, keeping track of the time spent on any packet and fragmenting the time for any tick, stopping the processing as soon as possible. In order to implement such mechanism, the polling handler needs to change, returning the number of packets processed. While the intended logic is not part of this patch, the polling KPI is broken by this commit, adding an int return value and the new flag IFCAP_POLLING_NOCOUNT (which will signal that the return value is meaningless for the installed handler and checking should be skipped). Bump __FreeBSD_version in order to signal such situation. Reviewed by: emaste Sponsored by: Sandvine Incorporated Notes: svn path=/head/; revision=193096

* Switch to using a normal mutex instead of a spin mutex.Benno Rice2008-06-112-22/+30
| | | | | | | | | | | | | | We still use the interrupt filter due to performance problems that show up if we don't. The main problem seen is that, due to the interrupt being edge triggered, we occasionally miss interrupts which leads us to not notice that we can transmit more packets. Using the new approach, which just schedules a task on a taskqueue, we are guaranteed to have the task run even if the interrupt arrived while we were already executing. If we were to use an ithread the system would mask the interrupt while the handler is run and we'd miss interrupts. Notes: svn path=/head/; revision=179719

* This is a rewritten driver for the SMSC LAN91C111. It's based in part on theBenno Rice2008-06-063-0/+1660
sn(4) driver and also looking at newer drivers. The reason for the rewrite is to support MII and to try and resolve some performance issues found when trying to use the sn(4) driver on the Gumstix network boards. For reference, the SMSC LAN91C111 is a non-PCI ethernet part whose lineage dates back to Ye Olde Days of ISA. It seems to get some use in the embedded space these days on parts lacking on-board MACs or on-board PCI controllers, such as the XScale PXA line of ARM CPUs. This also includes a driver for the SMSC LAN83C183 10/100 PHY. Man page to follow. Notes: svn path=/head/; revision=179592
