2015-12-14Add initial 802.11n support to the iwm(4) driver.stsp3-128/+495
Adds support for HT MCS 0-7 (theoretical limit 65 Mbit/s) and the reception of A-MSDU and A-MPDU aggregated frames. None of the optional 11n features are supported for now. MIMO, 40Mhz channels, short guard interval, etc. are left for future work. And we're not sending A-MSDU or A-MPDU frames yet either. Tested with various 11a/b/g/n access points. With some APs I'm seeing a noticable increase in throughput, especially on 5Ghz. Also, fix automatic rate selection by using the current Tx rate selected by AMRR as the upper bound for the firmware's rate table and updating the firmware's table whenever AMRR switches Tx rate, rather than setting the table just once after association and ignoring AMRR updates. ok mpi@ krw@ (earlier version), ok jasper@

2015-12-12x2APIC is currently enabled on HV guests only, not on bare metal, toreyk1-1/+8
speedup interrupt handling on virtual machines. Unfortunately it is broken on Xen 4.2 or older, so use the early pvbus detection to drop the advertised x2APIC CPU feature. Xen has fixed this in late 2013, but the problem still shows up in "the Cloud" (it doesn't seem to affect others as they either use legacy APIC or Xen IPIs).

2015-12-12Identify hypervisors before configuring other children of the mainbusreyk5-42/+72
(bios, CPU, interrupt handlers, pvbus). This splits the pvbus attach function into two parts: pvbus_identify() to scan the CPUID registers for supported hypervisors and pvbus_attach() to attach the bus, print information, and configure the children. This will be needed for Xen and KVM, as discussed with mikeb@ and sf@ OK mlarkin@

Do not set the "Port Number", "Hub Address" and "Split Completion Mask" fields in Isochronous Queue Heads for high-speed devices.

2015-12-09Correct the response string lengthmikeb1-6/+13
Apparently length values returned by XenStore depend on which operation has been requested: for instance XS_READ will always return an strlen() result without accounting for the trailing NUL character, however XS_LIST will return length that includes it. While staying within our data buffer limit (xsm_dlen) we can readjust the length of the resulting string accordingly.

2015-12-09rework the if_start mpsafe serialisation so it can serialise arbitrary workdlg1-7/+7
work is represented by struct task. the start routine is now wrapped by a task which is serialised by the infrastructure. if_start_barrier has been renamed to ifq_barrier and is now implemented as a task that gets serialised with the start routine. this also adds an ifq_restart() function. it serialises a call to ifq_clr_oactive and calls the start routine again. it exists to avoid a race that kettenis@ identified in between when a start routine discovers theres no space left on a ring, and when it calls ifq_set_oactive. if the txeof side of the driver empties the ring and calls ifq_clr_oactive in between the above calls in start, the queue will be marked oactive and the stack will never call the start routine again. by serialising the ifq_set_oactive call in the start routine and ifq_clr_oactive calls we avoid that race. tested on various nics ok mpi@

2015-12-08Driver for XenStore, the configuration storagemikeb4-1/+840
XenStore provides a hierarchical storage for Xen configuration in a style of an OpenFirmware. Itself it's an interrupt driven producer/consumer interface with two 1kb rings for input and output. It's required in order to do virtual device discovery and device configuration (fetch MAC address, various parameters). With input from and OK mlarkin, reyk

2015-12-08When iwm(4) moves to AUTH state it asks the firmware for a "time event" tostsp3-46/+53
prevent it from moving off-channel during association. The firmware issues interrupts at beginning and end of the time event. The driver tried detecting the beginning with a tsleep() in the newstate task followed by a wakeup() from the interrupt handler. However, sometimes the newstate task did not get scheduled until the time event had already passed, and association was aborted. In rare cases the newstate task would even sleep forever and the iwm(4) interface would stop working until reboot. Fix these issues by issuing the time event and continuing association without checking for a "go" from the firmware. Our kernel does not provide the scheduling guarantees required for such precise synchronization so association is more likely to fail with the additional check than without. ok mpi@ tedu@
