2019-03-07build: convert usb.mak to KconfigPaolo Bonzini1-1/+1
Instead of including the same list of devices for each target, let the host controllers select CONFIG_USB and make the devices default to present whenever USB is available. Done with the following script: while read i; do i=${i%=y}; i=${i#CONFIG_} sed -i -e'/^config '$i'$/!b' -en \ -e'a\' -e' default y\' -e' depends on USB' \ `grep -lw $i hw/*/Kconfig` done < default-configs/usb.mak followed by adding "select USB" on the host controllers.

2018-01-26usb: Remove legacy -usbdevice options (host, serial, disk and net)Thomas Huth1-1/+1
The option have been marked as deprecated since QEMU 2.10, and so far nobody complained that the host, serial, disk and net options are urgently required anymore. So let's now get rid at least of this legacy pile, to simplify the usb code quite a bit. This patch removes the usbdevices host, serial, disk and net. These devices use their own complicated parameter parsing mechanisms, so they are just ugly to maintain, without real benefit for the users (the users can use the corresponding "-device" parameters instead which have the same complexity as the "-usbdevice" devices here). Note that the other rather simple -usbdevice options (mouse, tablet, etc.) are not removed yet (the code is really simple here, so it does not hurt much to keep it), as well as the two devices "braille" and "bt" which are easier to use with -usbdevice than with -device.

Boards that do not include an USB controller should not provide USB devices. However, when running "qemu-system-s390x -device help" for example, there's still a usb-hub, usb-kbd, usb-mouse and usb-tablet in the list of "supported" devices.

2014-05-09libcacard: remove libcacard-specific CFLAGS and LIBS from global varsMichael Tokarev1-0/+1

Use the cflags only where really used (for two mentioned files), and libs only where needed. While at it, rename variables to better reflect reality: libcacard_* is really nss_*. This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs (ditto for _cflags). But in order to fix it, some more preparations should be made first. So add a FIXME comment.

2013-01-08usbredir: Add support for buffered bulk input (v2)Hans de Goede1-1/+1
Buffered bulk mode is intended for bulk *input* endpoints, where the data is of a streaming nature (not part of a command-response protocol). These endpoints' input buffer may overflow if data is not read quickly enough. So in buffered bulk mode the usb-host takes care of the submitting and re-submitting of bulk transfers. Buffered bulk mode is necessary for reliable operation with the bulk in endpoints of usb to serial convertors. Unfortunatelty buffered bulk input mode will only work with certain devices, therefor this patch also adds a usb-id table to enable it for devices which need it, while leaving the bulk ep handling for other devices unmodified. Note that the bumping of the required usbredir from 0.5.3 to 0.6 does not mean that we will now need a newer usbredir release then qemu-1.3, .pc files reporting 0.5.3 have only ever existed in usbredir builds directly from git, so qemu-1.3 needs the 0.6 release too. Changes in v2: -Split of quirk handling into quirks.c Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2012-11-01usb: Add packet combining functionsHans de Goede1-1/+1
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).

2012-07-12usb: add usb attached scsi emulationGerd Hoffmann1-0/+1
$subject says all. First cut. It's a pure UAS (usb attached scsi) emulation, without BOT (bulk-only transport) compatibility. If your guest can't handle it use usb-storage instead. The emulation works like any other scsi hba emulation (eps, lsi, virtio, megasas, ...). It provides just the HBA where you can attach scsi devices as you like using '-device'. A single scsi target with up to 256 luns is supported. For now only usb 2.0 transport is supported. This will change in the future though as I plan to use this as playground when codeing up & testing usb 3.0 transport and streams support in the qemu usb core and the xhci emulation. No migration support yet. I'm planning to add usb 3.0 support first as this probably requires saving additional state. Special thanks go to Paolo for bringing the qemu scsi emulation into shape, so this can be added nicely without having to touch a single line of scsi code.
