2016-01-20make AUDIO_GETDEV ioctl return the device name (ex "azalia0") ratherratchov1-2/+6
than driver specific strings. ok kettenis
2016-01-20Set segflg member of uio struct with symbolic enum valuestefan1-2/+2
instead of using magic numbers. No binary change. Diff from Martin Natano. ok deraadt@
2016-01-20Don't bump output errors when when tx ring is fullmikeb1-5/+3
Reported by Jonathon Sisson <openbsd at j3z ! org>, thanks!
2016-01-20Set byte order the default encoding in the attach method toratchov1-2/+6
native byte order. No behaviour change, as attach time parameters are just hints, except thay this makes audioctl output nicer if the device was never opened.

2016-01-20add hidmt, a HID-layer driver for multitouch touchpads that conformjcs6-4/+772
to the "Windows Precision Touchpad" standard. when a compatible device is found, hidmt claims all report ids and switches the device into multitouch packet mode. add imt, an i2c-HID driver that sits between ihidev and hidmt

2016-01-19Mask interrupts on boot, masking/unmasking is handled by stop/initmikeb1-1/+2
2016-01-19Fix a few issues in the xnf transmit pathmikeb1-6/+9
A crash reported by Jonathon Sisson is caused by incorrect calculation of available descriptors on the tx ring. While here, split the mbuf chain so that we won't unload the whole thing in the txeof before removing grant table references from transmit descriptors.
2016-01-19Cast evtchn_mask to a char pointer for an isset operationmikeb1-4/+5
When testing evtchn_mask bits we need to treat the array as a bit matrix for an isset macro to test correct bits. Reported by reyk@ some time ago, Wei Liu <wei ! liu2 at citrix !com> figured out how to reproduce the problem. Thanks!

2016-01-18Fixup a hang while performing a read operation on XenStoremikeb1-4/+7
Reyk has reported an issue that turned out to be an incorrect calculation of bytes available for reading. This diff also places missed semaphore releases in the xs_start and makes 'left' a size_t in xs_ring_{get,put}.

2016-01-15Detach emulated network devices if Netfront driver is enabledmikeb4-25/+26
Xen doesn't provide a way for a guest to decide which model of the interface is selected in the VM configuration and therefore there's no simple way for Netfront and emulated devices to co- exist on the same system. Emulated em(4) or re(4) drivers will take over if xnf(4) driver is disabled or not compiled in. Idea and OK reyk

2016-01-14Several fixes for dwiic(4).kettenis2-50/+60
* Properly map bus space; using BUS_SPACE_MAP_PREFATCHABLE is not agood idea as it may lead to reordering or merging of register writes in the store buffer. * Properly implement the iic(4) operations in dwiic_i2c_exec(). * Keep timings set up by the firmware if the SSCN and FMCN methods aren't available. ok jcs@

2016-01-13Change aml_find_node() such that it only walks down the tree and doesn'tkettenis2-14/+14
traverse sideways. This seems to be what all callersexpect it to do, and fixes a bug in dwiic(4) where it would try to access i2c devices on busses they're not attached to. If there is any fallout from this change, the right thing to do is probably to make sure callers pass the right node. While there, change the return type to void, as the return value was useless and none of the callers looked at it. ok mlarkin@

2016-01-13Create rx and tx fragment maps with a page size boundary restrictionmikeb2-4/+8
We need to ensure that rx and tx fragments do not cross page boundary since grant table reference can only point to a complete page. Add a couple of kernel assertions in the dma map loading code to catch these problems early in the future.

2016-01-13Don't confuse the HID descriptor address (which really is an office into thekettenis3-6/+15
register space of the i2c device) with the i2c address. For i2c busses enumerated by ACPI we get the address from the I2C Serial Bus Connection Resource Descriptor returned by the _CRS methide of the i2c device. Pass the HID descriptor address in the ia_size member. ok jcs@
