| | | | | | | | | | | | | | | The QCA9565 is a 1x1 2.4GHz 11n chip with integrated on-chip bluetooth.

* Add pipe2() system call.Jilles Tjoelker2013-05-014-0/+21
| | | | | | | | | | | | | | | | The pipe2() function is similar to pipe() but allows setting FD_CLOEXEC and O_NONBLOCK (on both sides) as part of the function. If p points to two writable ints, pipe2(p, 0) is equivalent to pipe(p). If the pointer is not valid, behaviour differs: pipe2() writes into the array from the kernel like socketpair() does, while pipe() writes into the array from an architecture-specific assembler wrapper.

* Add accept4() system call.Jilles Tjoelker2013-05-016-25/+70
| | | | | | | | | | | | | | | | | | The accept4() function, compared to accept(), allows setting the new file descriptor atomically close-on-exec and explicitly controlling the non-blocking status on the new socket. (Note that the latter point means that accept() is not equivalent to any form of accept4().) The linuxulator's accept4 implementation leaves a race window where the new file descriptor is not close-on-exec because it calls sys_accept(). This implementation leaves no such race window (by using falloc() flags). The linuxulator could be fixed and simplified by using the new code. Like accept(), accept4() is async-signal-safe, a cancellation point and permitted in capability mode. Notes: svn path=/head/; revision=250154

More, CPU instructions XSAVE and XSAVEOPT could write the mask without e.g. XFEATURE_ENABLED_SSE, after the VZEROALL. The check prevents the restoration of the otherwise valid FPU save area.

* The Intel PMC architectural events have encodings which are identical toDavide Italiano2013-04-302-25/+49
| | | | | | | | | | | | | | | | | | | | those of some non-architectural core events. This is not a problem in the general case as long as there's an 1:1 mapping between the two, but there are few exceptions. For example, 3CH_01H on Nehalem/Westmere represents both unhalted-reference-cycles and CPU_CLK_UNHALTED.REF_P. CPU_CLK_UNHALTED.REF_P on the aforementioned architectures does not measure reference (i.e. bus) but TSC, so there's the need to disambiguate. In order to avoid the namespace collision rename all the architectural events in a way they cannot be ambigous and refactor the architectural events handling function to reflect this change. While here, per Jim Harris request, rename iap_architectural_event_is_unsupported() to iap_event_is_architectural().

* socket: Make shutdown() wake up a blocked accept().Jilles Tjoelker2013-04-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | A blocking accept (and some other operations) waits on &so->so_timeo. Once it wakes up, it will detect the SBS_CANTRCVMORE bit. The error from accept() is [ECONNABORTED] which is not the nicest one -- the thread calling accept() needs to know out-of-band what is happening. A spurious wakeup on so->so_timeo appears harmless (sleep retried) except when lingering on close (SO_LINGER, and in that case there is no descriptor to call shutdown() on) so this should be fairly safe. A shutdown() already woke up a blocked accept() for TCP sockets, but not for Unix domain sockets. This fix is generic for all domains. This patch was sent to -hackers@ and -net@ on April 5.

* Add a new driver to support the Intel Non-Transparent Bridge(NTB).Carl Delsey2013-04-2910-0/+2904
| | | | | | | | | | | | | | | | | | | | | | | The NTB allows you to connect two systems with this device using a PCI-e link. The driver is made of two modules: - ntb_hw which is a basic hardware abstraction layer for the device. - if_ntb which implements the ntb network device and the communication protocol. The driver is limited at the moment to CPU memcpy instead of using DMA, and only Back-to-Back mode is supported. Also the network device isn't full featured yet. These changes will be coming soon. The DMA change will also bring in the ioat driver from the project branch it is on now. This is an initial port of the GPL/BSD Linux driver contributed by Jon Mason from Intel.
