2012-09-11tcg/optimize: fix if/else/break coding styleAurelien Jarno

2012-09-11tcg/optimize: swap brcond/setcond arguments when possibleAurelien Jarno
brcond and setcond ops are not commutative, but it's easy to compute the new condition after swapping the arguments. Try to always put the constant argument in second position like for commutative ops, to help backends to generate better code.

2012-09-11xhci: update port handlingGerd Hoffmann
This patch changes the way xhci ports are linked to USBPorts. The fixed 1:1 relationship between xhci ports and USBPorts is gone. Now each USBPort represents a physical plug which has usually two xhci ports assigned: one usb2 and ond usb3 port. usb devices show up at one or the other, depending on whenever they support superspeed or not. This patch also makes the number of usb2 and usb3 ports runtime configurable by adding 'p2' and 'p3' properties. It is allowed to have different numbers of usb2 and usb3 ports. Specifying p2=4,p3=2 will give you an xhci adapter which supports all speeds on physical ports 1+2 and usb2 only on ports 3+4.
2012-09-11xhci: update register layoutGerd Hoffmann
Change the register layout to be a bit more sparse and also not depend on the number of ports. Useful when for making the number of ports runtime-configurable.

2012-09-11xhci: drop bufferingGerd Hoffmann
This patch splits the xhci_xfer_data function into three. The xhci_xfer_data function used to do does two things: (1) copy transfer data between guest memory and a temporary buffer. (2) report transfer results to the guest using events. Now we three functions to handle this: (1) xhci_xfer_map creates a scatter list for the transfer and uses that (instead of the temporary buffer) to build a USBPacket. (2) xhci_xfer_unmap undoes the mapping. (3) xhci_xfer_report sends out events. The patch also fixes reporting of transaction errors which must be reported unconditinally, not only in case the guest asks for it using the ISP flag. [ v2: fix warning ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-09-11xhci: rip out background transfer codeGerd Hoffmann
original xhci code (the one which used libusb directly) used to use 'background transfers' for iso streams. In upstream qemu the iso stream buffering is handled by usb-host & usb-redir, so we will never ever need this. It has been left in as reference, but is dead code anyway. Rip it out.

2012-09-11usb-redir: Ensure our peer has the necessary caps when redirecting to XHCIHans de Goede
In order for redirection to work properly when redirecting to an emulated XHCI controller, the usb-redir-host must support both usb_redir_cap_ep_info_max_packet_size and usb_redir_cap_64bits_ids, reject any devices redirected to an XHCI controller when these are not supported.

2012-09-11usb-redir: Get rid of unused async-struct dev memberHans de Goede
This is a preparation patch for completely getting rid of the async-packet struct in usb-redir, instead relying on the (new) per ep queues in the qemu usb core. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-09-11usb-redir: Get rid of local shadow copy of packet headersHans de Goede
The shadow copy only serves as an extra check (besides the packet-id) to ensure the packet we get back is a reply to the packet we think it is. This check has never triggered in all the time usb-redir is in use now, and since the verified data in the returned packet-header is not used otherwise, removing the check does not open any possibilities for the usbredirhost to confuse us. This is a preparation patch for completely getting rid of the async-packet struct in usb-redir, instead relying on the (new) per ep queues in the qemu usb core.

2012-09-11usb-redir: Don't delay handling of open events to a bottom halfHans de Goede
There is no need for this, and doing so means that a backend trying to write immediately after an open event will see qemu_chr_be_can_write returning 0, which not all backends handle well as there is no wakeup mechanism to detect when the frontend does become writable.

2012-09-11usb-redir: Never return USB_RET_NAK for async handled packetsHans de Goede
USB_RET_NAK is not a valid response for async handled packets (and will trigger an assert as such). Also drop the warning when receiving a status of cancelled for packets not cancelled by qemu itself, this can happen when a device gets unredirected by the usbredir-host while transfers are pending.
