2016-08-15For some reason the RTL8211E PHY on the Banana Pi responds to both address 0Mark Kettenis
and 1. As a result rgephy(4) attaches twice. Prevent this from happening by passing the PHY address, which is part of the device tree, down from the bus-specific glue to the generic driver code.
2016-08-15Remove IWM_CMD_SYNC, which expands to zero while all the otherStefan Sperling
IWM_CMD_* values are bit flags. The same was done 2 years ago in Linux git commit a10229271946731959b2269370d0492d88cfab23.
2016-08-14u_quad_t -> uint64_tDavid Gwynne
de is amazing(tm). it really should be cut back and simplified a bit.
2016-08-14change some types in bio from u_quad_t to uint64_t, and fix casts inDavid Gwynne
drivers that fill that field in too. quad types are going away.
2016-08-14replace u_quad_t with uint64_t.David Gwynne
guenther is proposing the removal of u_quad_t. uint64_t is more portable. tested on a perc5 and perc6, no functional change.
2016-08-13Add the core of the code for dwge(4), a driver for the Synopsis DesignwareMark Kettenis
GMAC core which is used on the Allwinner A20 SoCs and later SoCs in the Allwinner family. Since this core is very likely to show up the base of other devices, it gets to live here in dev/ic. Ported from NetBSD (where it is named awge(4)) by patrick@. Some further fixes by me. ok deraadt@

2016-08-05Switch pending event clearing to an atomic swap operationMike Belopuhov
Rather than performing an atomic bit clearing for every encountered event bit set we can adjust the code to perform an atomic swap of a single row of the events array and decrease the amount of expensive atomic operations. Same optimization as for Hyper-V. From FreeBSD.

2016-08-03Use atomic operations to manipulate event masking bitsMike Belopuhov
2016-08-03Remove the periodic timer and do rescheduling during Rx completionMike Belopuhov
This change adds a check into the Rx ring completion routine that schedules an interrupt task to be executed immediately after if consumer index has already advanced itself. The benefit of doing this compared to an additional loop after replenishing the ring (as done in FreeBSD for example) is that first of all this goes through the loop in the taskqueue thread with a yeild check to prevent CPU hogging and second is that it triggers Tx completion as well since interrupt handler runs both.
2016-08-03Use an atomic operation to clear pending event bitsMike Belopuhov
Pending event bits are located in a shared memory and are potentially accessed by multiple CPUs running dom0 and the guest VM. It appears that a failure to synchronize changes to this shared memory leads to race conditions resulting in the guest missing out on notifications.

2016-08-01Set SDEV_UMASS on all umass devices, even when they use ATAPI orKenneth R Westerback
UFI command sets. Probe all the LUNs a device reports instead of assuming ATAPI and UFI devices always have 1 LUN. Motivated by the device David Vasek reported as claiming to be ATAPI but wanting to use >1 LUN. Committing quickly to smoke out the inevitable device that works in the exact opposite way.

2016-07-29Add a periodic timer to workaround missing completion eventsMike Belopuhov
2016-07-29Disable receive ring slot accountingMike Belopuhov
In the Netfront case it appears that by having scheduler decide when to run the workload we don't need to involve additional mechanisms to artificially limit resource availability to achieve better performance under heavy load. On the contrary, by performing a single pass through Rx and Tx completion rings and having scheduler decide when to run the next attempt, we limit the amount of time spent in the packet processing and achieve system responsiveness.
2016-07-29Move xen interrupt handlers to dedicated task queuesMike Belopuhov
Handling receive and transmit for multiple networking interfaces in a "shared interrupt" within normal interrupt vector code path introduces too much delay from the hypervisor POV which prevents it from injecting further completion event interrupts for Rx and Tx queues. Additionally, Netfront backend driver includes a mechanism to detect Rx ring stalls and "turn the carrier off" when the guest is not replenishing the ring (e.g. due to missing completion interrupts) that relies on guest waking up periodically and making sure that the Rx ring completion handling is progressing. Having tried both task queue + timeout and interrupts + timeout approaches, it appears that using the task queue is more flexible and provides superior performance under heavy network load.
