2011-10-13usb-hid: activate usb tablet / mouse after migration.Gerd Hoffmann
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: Gerd Hoffmann <kraxel@redhat.com>

2011-08-10usb/hid: add hid_pointer_activate, use itGerd Hoffmann
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: Gerd Hoffmann <kraxel@redhat.com>

2011-08-04usb-hid: split hid code to hw/hid.[ch]Gerd Hoffmann
Almost pure code motion. Unstatic hid interface functions and add them to the header file. Some renames. Some code style cleanups. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-08-04usb-hid: add hid_has_events()Gerd Hoffmann
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: Gerd Hoffmann <kraxel@redhat.com>
2011-08-04usb-hid: add event callbackGerd Hoffmann
Add callback for event notification, which allows to un-usbify more functions. Also split separate hid_* functions for reset and release. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-08-04usb-hid: create & use HIDStateGerd Hoffmann
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: Gerd Hoffmann <kraxel@redhat.com>
2011-08-04usb: use iovecs in USBPacketGerd Hoffmann
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: Gerd Hoffmann <kraxel@redhat.com>

2011-06-14The USB tablet should not claim boot protocol support.Kevin O'Connor
The USB tablet advertises that it supports the "boot" protocol. However, its reports aren't "boot" protocol compatible. So, it shouldn't claim that. Signed-off-by: Kevin O'Connor <kevin@koconnor.net> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14Fix USB mouse Set_Protocol behaviorKevin O'Connor
The QEMU USB mouse claims to support the "boot" protocol (bInterfaceSubClass is 1). However, the mouse rejects the Set_Protocol command. The qemu mouse does support the "boot" protocol specification, so a simple fix is to enable the Set_Protocol request.

2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini
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.

2011-01-24usb keyboard: add event event queueGerd Hoffmann
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: Gerd Hoffmann <kraxel@redhat.com>
2011-01-24add event queueing to USB HIDPaolo Bonzini
The polling nature of the USB HID device makes it very hard to double click or drag while on a high-latency VNC connection. This patch, based on work done in the Xen qemu-dm tree by Ian Jackson, fixes this bug by adding an event queue to the device. The event queue associates each movement with the correct button state, and remembers all button presses and releases as well.

2011-01-20usb-hid: modifiers should generate an eventAurelien Jarno

2011-01-16USB keyboard emulation key mapping errorMichael Tokarev
The USB keyboard emulation's translation table in hw/usb-hid.c doesn't match the codes actually sent for the Logo (a.k.a. "Windows") or Menu keys. This results in the guest OS not being able to receive these keys at all when the USB keyboard emulation is being used. In particular, both the keymap in /usr/share/kvm/keymaps/modifiers and the evdev table in x_keymap.c map these keys to 0xdb, 0xdc, and 0xdd, while usb_hid_usage_keys[] seems to be expecting them to be mapped to 0x7d, 0x7e, and 0x7f. The attached patch seems to fix the problem, at least in my (limited) testing. http://bugs.debian.org/578846 http://bugs.debian.org/600593 (cloned from the above against different pkg) https://bugs.launchpad.net/qemu/+bug/584139 Signed-Off-By: Brad Jorsch <anomie@users.sourceforge.net> Signed-Off-By: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-11usb: hid: change serial number to "42".Gerd Hoffmann
It would be nice to have some way to signal our hid devices support remote wakeup. There is a descriptor bit for that of course. Problem with using is one is that older qemu versions used to set the bit even though they did *not* support remote wakeup. Bummer. This patch changes the serial number of our hid devices from "1" to "42" to signal "it is safe to enable remote wakeup". The serial number was choosen because it isn't used for anything and it is available in sysfs so it is easy to match it using udev rules like this: ACTION=="add", SUBSYSTEM=="usb", \ ATTR{product}=="QEMU USB Tablet", ATTR{serial}=="42", \ RUN+="usb_enable_autosuspend %p" Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-01-11usb: move USB_REQ_{GET,SET}_CONFIGURATION handling to common codeGerd Hoffmann
This patch adds fields to the USBDevice struct for the current speed (hard-wired to full speed for now) and current device configuration. Also a init function is added which inializes these fields. This allows USB_REQ_{GET,SET}_CONFIGURATION handling to be moved to common code. For most drivers the conversion is trivial ad they support a single configuration only anyway. One exception is bluetooth where some device-specific setup code runs after get/set configuration. The other is usb-net which actually has two configurations so the the code to check for the active configuration has been adapted. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2010-03-19Rewrite mouse handlers to use QTAILQ and to have an activation functionAnthony Liguori
And convert usb-hid to use it (to avoid regression with bisection) Right now, when we do info mice and we've added a usb tablet, we don't see it until the guest starts using the tablet. We implement this behavior in order to provide a means to delay registration of a mouse handler since we treat the last registered handler as the current handler. This is a usability problem though as we would like to give the user feedback that they've either 1) not added an absolute device 2) there is an absolute device but the guest isn't using it 3) we have an absolute device and it's active. By using QTAILQ and having an explicit activation function that moves the handler to the front of the queue, we can implement the same semantics as before with respect to automatically switching to usb tablet while providing the user with a whole lot more information.

2010-02-19USB HID does not support Set_IdleKevin O'Connor
I found that the QEMU USB keyboard support does not work properly with the Set_Idle command. Once a non-zero value is given to Set_Idle, then the keyboard reports an event on every poll - not based on the time issued in the Set_Idle command. I changed the code (see patch below) and it works for me. I'm not that familiar with the qemu internals, so I'm not sure if this is the best way to implement this feature. -Kevin Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-01-07fix usb-hid SET_IDLE behaviour (Stefano Stabellini)aliguori
the usb-hid spec states that the SET_IDLE request has a 16bit value, where the upper byte specifies the idle rate (currently unimplemented, we handle only the 0 case, meaning infinite duration) and the lower byte specifies the report id (0 means all reports). In our code we do idle = value, while it should be idle = "upper byte", especially if the guest issues a GET_IDLE, we should return only the idle rate while we are returning only the report id. In practice it doesn't make much difference because I have only seen SET_VALUE with both bytes set to 0 so far, but still it is wrong.
