2013-12-10net/cadence_gem: Fix small packet FCS strippingPeter Crosthwaite1-5/+8
The minimum packet size is 64, however this is before FCS stripping occurs. So when FCS stripping the minimum packet size is 60. Fix.

2013-12-06vfio-pci: Fix Nvidia MSI ACK through 0x88000 quirkAlex Williamson1-1/+29
When MSI is enabled on Nvidia GeForce cards the driver seems to acknowledge the interrupt by writing a 0xff byte to the MSI capability ID register using the PCI config space mirror at offset 0x88000 from BAR0. Without this, the device will only fire a single interrupt. VFIO handles the PCI capability ID/next registers as virtual w/o write support, so any write through config space is currently dropped. Add a check for this and allow the write through the BAR window. The registers are read-only anyway. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2013-12-01xen: fix two errors when debug is enabledWei Liu1-1/+2
This patch fixes: 1. build error in xen_pt.c when XEN_PT_LOGGING_ENABLED is defined 2. debug output format string error when DEBUG_XEN is defined In the second case I also have the output info in consistent with the output in mapping function - that is, print start_addr instead of phys_offset.

2013-11-26xhci: Call usb_device_alloc/free_streamsHans de Goede1-0/+117
Note this code is not as KISS as I would like, the reason for this is that the Linux kernel interface wants streams on eps belonging to one interface to be allocated in one call. Things will also work if we do this one ep at a time (as long as all eps support the same amount of streams), but lets stick to the kernel API.

2013-11-26uas: Fix response iu struct definitionHans de Goede1-10/+8
This patch mirrors a patch to the Linux uas kernel driver which I've just submitted. It looks like the qemu uas struct definitions were taken from the Linux kernel driver, and have inherited the same mistake. Besides fixing the response iu struct, the patch also drops the add_info parameter from the usb_uas_queue_response() function, it is always 0 anyways, and expressing 3 zero-bytes as a function argument is a bit hard. Below is the long explanation for this change taken from the kernel commit: The response iu struct before this patch has a size of 7 bytes, which is weird since all other iu-s are explictly padded to a multiple of 4 bytes. Submitting a 7 byte bulk transfer to the status endpoint of a real uasp device when expecting a response iu results in an USB babble error, as the device actually sends 8 bytes. Up on closer reading of the UAS spec: http://www.t10.org/cgi-bin/ac.pl?t=f&f=uas2r00.pdf The reason for this becomes clear, the 2 entries in "Table 17 — RESPONSE IU" are numbered 4 and 6, looking at other iu definitions in the spec, esp. multi-byte fields, this indicates that the ADDITIONAL RESPONSE INFORMATION field is not a 2 byte field as one might assume at a first look, but is a multi-byte field containing 3 bytes. This also aligns with the SCSI Architecture Model 4 spec, which UAS is based on which states in paragraph "7.1 Task management function procedure calls" that the "Additional Response Information" output argument for a Task management function procedure call is 3 bytes. Last but not least I've verified this by sending a logical unit reset task management call with an invalid lun to an actual uasp device, and received back a response-iu with byte 6 being 0, and byte 7 being 9, which is the responce code for an invalid iu, which confirms that the response code is being reported in byte 7 of the response iu rather then in byte 6.
