Our ehci code does not implement wakeup support, so claiming support for it with usb-tablet in USB-2 mode causes all tablet events to get lost. http://bugzilla.redhat.com/show_bug.cgi?id=929068Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> (cherry picked from commit aa1c9e97) Signed-off-by: NMichael Roth <mdroth@linux.vnet.ibm.com>

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.

Our ehci code has is capable of significantly lowering the wakeup rate for the hcd emulation while the device is idle. It is possible to add similar code ot the uhci emulation, but that simply is not there atm, and there is no reason why a (virtual) usb-tablet can not be a USB-2 device. Making usb-hid devices connect to the emulated ehci controller instead of the emulated uhci controller on vms which have both lowers the cpuload for a fully idle vm from 20% to 2-3% (on my laptop). An alternative implementation to using a property to select the tablet type, would be simply making it a new device type, ie usb-tablet2, but the downside of that is that this will require libvirt changes to be available through libvirt at all, and then management tools changes to become the default for new vms, where as using a property will automatically get any pc-1.3 type vms the lower cpuload.

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() Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

QEMU exposes its version to the guest's hardware and in some cases that is wrong (e.g. Windows prints messages about driver updates when you switch the QEMU version). There is a new field now on the struct QEmuMachine, hw_version, which may contain the version that the specific machine should report. If that field is set, then that machine will report that version to the guest. Signed-off-by: NCrístian Viana <vianac@linux.vnet.ibm.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Devices must specify which endpoint has data to transfer now. The plan is to use the usb_wakeup() not only for remove wakeup support, but for "data ready" signaling in general, so we can move away from constant polling to event driven usb device emulation.

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.

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.

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. Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

qemu uses the ps/2 mouse by default. The usb tablet (or mouse) is activated as soon as qemu sees some guest activity on the device, i.e. polling for HID events. That used to work fine for both fresh boot and migration. Remote wakeup support changed the picture though: There will be no polling after migration in case the guest suspended the usb bus, waiting for wakeup events. Result is that the ps/2 mouse stays active. Fix this by activating the usb tablet / mouse in post_load() in case the guest enabled remote wakeup. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

HID reorganziation broke the usb tablet in windows xp. The reason is that xp activates idle before it starts polling, which creates a chicken-and-egg issue: We don't call hid_pointer_poll because there are no pending events. We don't get any events because the activation code in hid_pointer_poll is never executed and thus all pointer events are routed to the PS/2 mouse by qemu. Fix this by creating a hid_pointer_activate function and call it from usb-hid when the guest sets the idle state. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Add hid_has_events function, use it to figure whenever there are pending events instead of checking and updating USBHIDState->changed. Setting ->changed to 1 on init is removed, that should have absolutely no effect as the initial state of ->idle is 0 so we report hid state anyway until the guest configures some idle time. Also should clear ->idle on reset. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

First step in separating out the HID emulation code from usb-hid, so it can be reused without creating a dummy usb device like bluetooth does. This creates a HIDState struct, moves the non-usbish fields from USBHIDStruct there. Renames non-usbish structs, defines and functions from usb* to hid*. Adapts the code to that. Also cleans up a bunch of code style issues along the way. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Zap data pointer from USBPacket, add a QEMUIOVector instead. Add a bunch of helper functions to manage USBPacket data. Switch over users to the new interface. Note that USBPacket->len was used for two purposes: First to pass in the buffer size and second to return the number of transfered bytes or the status code on async transfers. There is a new result variable for the latter. A new status code was added to catch uninitialized result. Nobody creates iovecs with more than one element (yet). Some users are (temporarely) limited to iovecs with a single element to keep the patch size as small as possible. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

This patch adds a event queue to the usb keyboard. This makes sure the guest will see all key events even if they come in bursts. With this patch applied sending Ctrl-Alt-Del using vncviewer's F8 menu works. Also with autosuspend enabled the first keypress on a suspended keyboard takes a little longer to be delivered to the guest because the usb bus must be resumed first. Without event queue this easily gets lost. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>
