      Make all static TypeInfos const · 8c43a6f0
      Andreas Färber 提交于
      Since 39bffca2 (qdev: register all
      types natively through QEMU Object Model), TypeInfo as used in
      the common, non-iterative pattern is no longer amended with information
      and should therefore be const.
      
      Fix the documented QOM examples:
      
       sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
      
      Since frequently the wrong examples are being copied by contributors of
      new devices, fix all types in the tree:
      
       sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
       sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
      
      This also avoids to piggy-back these changes onto real functional
      changes or other refactorings.

      usb: Don't allow USB_RET_ASYNC for interrupt packets · be41efde
      Hans de Goede 提交于
      It is tempting to use USB_RET_ASYNC for interrupt packets, rather then the
      current NAK + polling approach, but this causes issues for migration, as
      an async completed packet will not getting written back to guest memory until
      the next poll time, and if a migration happens in between it will get lost!
      
      Make an exception for host devices, because:
      1) host-linux actually uses async completion for interrupt endpoints
      2) host devices don't migrate anyways
      
      Ideally we would convert host-linux.c to handle (input) interrupt endpoints in
      a buffered manner like it does for isoc endpoints, keeping multiple urbs
      submitted to ensure the devices timing requirements are met, as well as making
      its interrupt ep handling the same as other usb-devices.

      usb: split packet result into actual_length + status · 9a77a0f5
      Hans de Goede 提交于
      Since with the ehci and xhci controllers a single packet can be larger
      then maxpacketsize, it is possible for the result of a single packet
      to be both having transferred some data as well as the transfer to have
      an error.
      
      An example would be an input transfer from a bulk endpoint successfully
      receiving 1 or more maxpacketsize packets from the device, followed
      by a packet signalling halt.
      
      While already touching all the devices and controllers handle_packet /
      handle_data / handle_control code, also change the return type of
      these functions to void, solely storing the status in the packet. To
      make the code paths for regular versus async packet handling more
      uniform.
      
      This patch unfortunately is somewhat invasive, since makeing the qemu
      usb core deal with this requires changes everywhere. This patch only
      prepares the usb core for this, all the hcd / device changes are done
      in such a way that there are no functional changes.
      
      This patch has been tested with uhci and ehci hcds, together with usb-audio,
      usb-hid and usb-storage devices, as well as with usb-redir redirection
      with a wide variety of real devices.
      
      Note that there is usually no need to directly set packet->actual_length
      form devices handle_data callback, as that is done by usb_packet_copy()

      usb-host: handle guest-issued clear halt · a2498f76
      Gerd Hoffmann 提交于
      Most important here is to update our internal endpoint state so we know
      the endpoint isn't in halted state any more.  Without this usb-host
      tries to clear halt again with the next data transfer submitted.  Doing
      this twice is (a) not correct and (b) confuses some usb devices,
      rendering them non-functional in the guest.

      descriptive.  Host adapters are prefixed with "hch-" now, usb device
      emulations are prefixed with "dev-".  Fixup paths Makefile and include
      paths to make it compile.  No code changes.

      usb: Set USBEndpoint in usb_packet_setup(). · 079d0b7f
      Gerd Hoffmann 提交于
      With the separation of the device lookup (via usb_find_device) and
      packet processing we can lookup device and endpoint before setting up
      the usb packet.  So we can initialize USBPacket->ep early and keep it
      valid for the whole lifecycle of the USBPacket.  Also the devaddr and
      devep fields are not needed any more.

      usb: kill handle_packet callback · 7f74a56b
      Gerd Hoffmann 提交于
      All drivers except usb-hub use usb_generic_handle_packet.  The only
      reason the usb hub has its own function is that it used to be called
      with packets which are intended for downstream devices.  With the new,
      separate device lookup step this doesn't happen any more, so the need
      for a different handle_packet callback is gone.
      
      So we can kill the handle_packet callback and just call
      usb_generic_handle_packet directly.  The special hub handling in
      usb_handle_packet() can go away for the same reason.

      qdev: register all types natively through QEMU Object Model · 39bffca2
      Anthony Liguori 提交于
      This was done in a mostly automated fashion.  I did it in three steps and then
      rebased it into a single step which avoids repeatedly touching every file in
      the tree.
      
      The first step was a sed-based addition of the parent type to the subclass
      registration functions.
      
      The second step was another sed-based removal of subclass registration functions
      while also adding virtual functions from the base class into a class_init
      function as appropriate.
      
      Finally, a python script was used to convert the DeviceInfo structures and
      qdev_register_subclass functions to TypeInfo structures, class_init functions,
      and type_register_static calls.
      
      We are almost fully converted to QOM after this commit.
