2012-11-01combined-packet: Add a workaround for Linux usbfs + live migrationHans de Goede1-2/+5
Older versions (anything but the latest) of Linux usbfs + libusb(x), will submit larger (bulk) transfers split into multiple 16k submissions, which means that rather then all tds getting linked into the queue in one atomic operarion they get linked in a bunch at a time, which could cause problems if: 1) We scan the queue while libusb is in the middle of submitting a split bulk transfer 2) While this bulk transfer is pending we migrate to another host. The problem is that after 2, the new host will rescan the queue and combine the packets in one large transfer, where as 1) has caused the original host to see them as 2 transfers. This patch fixes this by stopping combinging if we detect a 16k transfer with its int_req flag set. This should not adversely effect performance for other cases as: 1) Linux never sets the interrupt flag on packets other then the last 2) Windows does set the in_req flag on each td, but will submit large transfers in 20k tds thus never triggering the check Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-11-01usb: Add packet combining functionsHans de Goede4-1/+194
Currently we only do pipelining for output endpoints, since to properly support short-not-ok semantics we can only have one outstanding input packet. Since the ehci and uhci controllers have a limited per td packet size guests will split large input transfers to into multiple packets, and since we don't pipeline these, this comes with a serious performance penalty. This patch adds helper functions to (re-)combine packets which belong to 1 transfer at the guest device-driver level into 1 large transger. This can be used by (redirection) usb-devices to enable pipelining for input endpoints. This patch will combine packets together until a transfer terminating packet is encountered. A terminating packet is a packet which meets one or more of the following conditions: 1) The packet size is *not* a multiple of the endpoint max packet size 2) The packet does *not* have its short-not-ok flag set 3) The packet has its interrupt-on-complete flag set The short-not-ok flag of the combined packet is that of the terminating packet. Multiple combined packets may be submitted to the device, if the combined packets do not have their short-not-ok flag set, enabling true pipelining. If a combined packet does have its short-not-ok flag set the queue will wait with submitting further packets to the device until that packet has completed. Once enabled in the usb-redir and ehci code, this improves the speed (MB/s) of a Linux guest reading from a USB mass storage device by a factor of 1.2 - 1.5. And the main reason why I started working on this, when reading from a pl2303 USB<->serial converter, it combines the previous 4 packets submitted per device-driver level read into 1 big read, reducing the number of packets / sec by a factor 4, and it allows to have multiple reads outstanding. This allows for much better latency tolerance without the pl2303's internal buffer overflowing (which was happening at 115200 bps, without serial flow control).

2012-11-01uhci: Don't crash on device disconnectHans de Goede1-0/+5
My recent uhci cleanup series has introduced a regression, where qemu sometimes crashes on a device disconnect. The problem is that the uhci code never checked for a device not / no longer existing, instead it was relying on usb_handle_packet accepting a NULL device. But since we now pass usb_handle_packet q->ep->dev, rather then just a local dev variable, we crash as q->ep == NULL due to the device no longer existing. This patch fixes this. Note that this patch also improves over the old behavior were we would: 1) create a queue for the device 2) create an async for the packet 3) have usb_handle_packet fail 4) destroy the async 5) wait for the queue to be idle for 32 frames 6) destroy the queue Which was rather sub-optimal.

2012-10-29s390: sclp ascii console supportHeinz Graalfs2-1/+307
This code adds console support by implementing SCLP's ASCII Console Data event. This is the same console as LPARs ASCII console or z/VMs sysascii. The console can be specified manually with something like -chardev stdio,id=charconsole0 -device sclpconsole,chardev=charconsole0,id=console0 Newer kernels will autodetect that console and prefer that over virtio console. When data is received from the character layer it creates a service interrupt to trigger a Read Event Data command from the guest that will pick up the received character byte-stream. When characters are echo'ed by the linux guest a Write Event Data occurs which is forwarded by the Event Facility to the console that supports a corresponding mask value. Console resizing is not supported. The character layer byte-stream is buffered using a fixed size iov buffer.

2012-10-29s390: sclp signal quiesce supportHeinz Graalfs3-0/+131
This implements the sclp signal quiesce event via the SCLP Event Facility. This allows to gracefully shutdown a guest by using system_powerdown notifiers. It creates a service interrupt that will trigger a Read Event Data command from the guest. This code will then add an event that is interpreted by linux guests as ctrl-alt-del.

2012-10-29s390: sclp event supportHeinz Graalfs6-2/+579
Several SCLP features are considered to be events. Those events don't provide SCLP commands on their own, instead they are all based on Read Event Data, Write Event Data, Write Event Mask and the service interrupt. Follow-on patches will provide SCLP's Signal Quiesce (via system_powerdown) and the ASCII console. Further down the road the sclp line mode console and configuration change events (e.g. cpu hotplug) can be implemented.

This adds a more generic infrastructure for handling Service-Call requests on s390. Currently we only support a small subset of Read SCP Info directly in target-s390x.
