2015-11-24fix tx ring accounting in myx_start.dlg1-20/+24
turns out i was calculating the number of packets (not descriptors) on the tx ring, and then using that as the free space for descriptors.

stack, is currently set to 25%. With 25% battery left, a typical modern laptop will have at least one hour runtime left. It is an arbitrary value, and other APM power layers in the kernel set CRITICAL to something like 5% or 10%, so set it to 10% for now. OK mlarkin@

2015-11-21The drm irq stuff isn't actually used on OpenBSD. Using the PCI devicekettenis2-7/+3
interrupt line register as the irq number doesn't really work as the contents of that register might be 0, and the code has checks for non-zero irq numbers in places. Insteadmake drm_dev_to_irq() return -1, which is an obviously bogus, but non-zero value. This should fix inteldrm(4) on recent Apple hardware.

2015-11-20shuffle struct ifqueue so in flight mbufs are protected by a mutex.dlg60-273/+317
the code is refactored so the IFQ macros call newly implemented ifq functions. the ifq code is split so each discipline (priq and hfsc in our case) is an opaque set of operations that the common ifq code can call. the common code does the locking, accounting (ifq_len manipulation), and freeing of the mbuf if the disciplines enqueue function rejects it. theyre kind of like bufqs in the block layer with their fifo and nscan disciplines. the new api also supports atomic switching of disciplines at runtime. the hfsc setup in pf_ioctl.c has been tweaked to build a complete hfsc_if structure which it attaches to the send queue in a single operation, rather than attaching to the interface up front and building up a list of queues. the send queue is now mutexed, which raises the expectation that packets can be enqueued or purged on one cpu while another cpu is dequeueing them in a driver for transmission. a lot of drivers use IFQ_POLL to peek at an mbuf and attempt to fit it on the ring before committing to it with a later IFQ_DEQUEUE operation. if the mbuf gets freed in between the POLL and DEQUEUE operations, fireworks will ensue. to avoid this, the ifq api introduces ifq_deq_begin, ifq_deq_rollback, and ifq_deq_commit. ifq_deq_begin allows a driver to take the ifq mutex and get a reference to the mbuf they wish to try and tx. if there's space, they can ifq_deq_commit it to remove the mbuf and release the mutex. if there's no space, ifq_deq_rollback simply releases the mutex. this api was developed to make updating the drivers using IFQ_POLL easy, instead of having to do significant semantic changes to avoid POLL that we cannot test on all the hardware. the common code has been tested pretty hard, and all the driver modifications are straightforward except for de(4). if that breaks it can be dealt with later. ok mpi@ jmatthew@

myx_start calculates the free space by reading the consumer index and doing some maths, which lets us avoid the interlocked cpu ops.

2015-11-16rework vge_start to avoid IFQ_POLLdlg1-54/+34
firstly, this checks for space in the tx ring before looking at the send queue. if there's no space, then IFF_OACTIVE is set and break. if there's space use IFQ_DEQUEUE to pull a packet off. if we fail to encapsulate it, it gets dropped. encap has been changed so the dmamaps the mbufs are loaded into are created with 7 segments instead of 32. this means we detect when the packet would overflow the tx descriptor at dmamap load time, rather than after we've looped over the segments writing them into the descriptor. we now use m_defrag to defrag the mbuf instead of allocating a new one and using m_copydata. now if we have any encap error on the first mbuf, we no longer set IFF_OACTIVE and wait for an interrupt that never comes to clear it. testing and (excellent) code review by richard proctor
