2016-05-07add support for changing the bus width and set the 4-bit mode capabilityJonathan Gray
ok patrick@ kettenis@
2016-05-06Reset the bus width back to 1-bit when resetting the host. Makes imxesdhc(4)Mark Kettenis
work on the cubox-i, whereu-boot leaves the controller in 4-bit mode.
2016-05-06Revert the previous commit. There still are bad interactions between theMark Kettenis
pagedaemon and the buffer cache. requested by deraadt@
2016-05-06Make sure we always update both bits that control the bus width. Also makeMark Kettenis
sure that we reset the bus width (to 1-bit) after powering up the bus. Apparently the register write fails if the bus isn't powered on. Implement the chip callback function and advertise 4-bit bus support. ok stsp@
2016-05-06Round the requested clock frequency down to a support value instead ofMark Kettenis
insisting on an exact match. Add support for a 50 MHz clock. ok stsp@

2016-05-05r1.10 of if_bnx.c effectively removed the limit on the number of segments inJonathan Matthew
the tx dma maps, apparently to allow heavily fragmented packets to be sent. The tx ring accounting in bnx_start assumed that the longest fragment chain we'd see was BNX_MAX_SEGMENTS, so sending a heavily fragmented packet when the ring was already full could cause it to overflow. In the 10 years since r1.10, we've started defragmenting packets if they won't fit in the dma map, so we can limit the maps to BNX_MAX_SEGMENTS again. While we're here, ensure there's always at least one slot on the tx ring free, for consistency between drivers. Fixes packet corruption seen by otto@ ok mpi@ dlg@
2016-05-05Bump up the clock to 25 MHz before trying to read the SCR register of an SDMark Kettenis
card. Data transfers don't seem to work on the Realtek RTS5229 Card Reader if the clock frequency is too low, and reading the SCR requires a data transfer.

value is 0 to match the behaviour when the callbacks are not set. Prevents a divide by zero in wsconsctl(8) reported by Caspar Schutijser. earlier version ok jung@ deraadt@ kettenis@
2016-05-04Use BUS_DMA_OVERRUN to cope with the broken DMA engine of the Davicom DM9102Mark Kettenis
found on some Sun sparc64 machines. This fixes the unrecoverable DMA errors people have been seeing ever since dlg@ made changes to the pool code that changes the memory layout.
2016-05-04Some hardware (such as the onboard dc(4) of the Netra X1) has a broken DMAMark Kettenis
engine that might attempt to read beyond the end of the buffer that was programmed. The IOMMU catches this "DMA overrun" and throws an unrecoverable error at us, at which point we have no choice but to panic. To avoid this implement a BUS_DMA_OVERRUN flag that maps an additional scratch page at the end of the vdma address range. DMA requests will spill over into this page, which just returns zeroes. Thanks to matthieu@ for giving me access to a machine with the problem. ok deraadt@, beck@
2016-05-04Initial support for MSI-X. Only supported on amd64 for now. I have diffs toMark Kettenis
actually use this in em(4) and xhci(4), but I'm not committing those yet because we almost certainly need to save and restore the MSI-X registers during suspend/resume. However, this allows mpi@ to play with multiple-vector support in networking hardware. Requested by mpi@ ok mlarkin@, mikeb@

2016-05-04Add high-speed support for SD cards. In theory this should double theMark Kettenis
transfer rates to and from the card. In practice the improvement will be smaller, but I am seeing serious improvement in the read speeds.
2016-05-04Don't mask pins configured as direct IRQ. Those are tied directly to the APICMark Kettenis
and don't generate a GPIO controller interrupt. Masking them menas devices relying on those APIC interrupts will break. Unbreaks the keyboard on the Asus x205ta, which got broken in rev 1.6.

2016-05-03Stop using a soft-interrupt context to process incoming network packets.Martin Pieuchot
Use a new task that runs holding the KERNEL_LOCK to execute mp-unsafe code. Our current goal is to progressively move input functions to the unlocked task.

2016-05-03implement bus_space_read_raw_X and bus_space_write_raw_XDavid Gwynne
with feedback from kettenis@ fixes building a kernel with xge, which might actually work on these machines now.
2016-05-03Make ip_forward() use the route entry fetched in in_ouraddr() when it isMartin Pieuchot
possible. This reduce the number of lookups to 1 for non-multicast traffic when PF is disable. Tested by Hrvoje Popovski who confirmed that benchmark numbers are now as good as with a single cache entry. ok visa@, bluhm@
2016-05-03Put back a panic() if an incoming packet already has a statekey.Martin Pieuchot
Apparently nobody can hit this condition anymore or people do not report bugs if their kernel do not panic. ok dlg@, sashan@
2016-05-03alias bus_space_{read,write}_raw to the non-raw counterpartsDavid Gwynne
busses are little endian, so the non-raw ops are raw anyway. fixes the kernel build after xge grew the use of the raw ops.

2016-05-02Simplify life for routing table implementations by requiring that rtable_walkJonathan Matthew
callbacks return EAGAIN if they modify the routing table. While we're here, simplify life for rtable_walk callers by moving the loop that restarts the walk on EAGAIN into rtable_walk itself. Flushing cloned routes on interface state changes becomes a bit more inefficient, but this can be improved later. ok mpi@ dlg@
2016-05-02Fix some issues wrt timestamp updating. The tmpfs_read() andMartin Natano
