From a557cdb3d6d001f7735d0f2c9d4a2f0c71912eed Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 5 Jan 2011 15:29:25 -0200 Subject: [PATCH 20/48] spice: add tablet support RH-Author: Gerd Hoffmann Message-id: <1294241382-17988-22-git-send-email-kraxel@redhat.com> Patchwork-id: 15750 O-Subject: [RHEL-6 kvm PATCH 21/38] spice: add tablet support Bugzilla: 642131 634153 615947 632458 631832 647865 RH-Acked-by: Uri Lublin RH-Acked-by: Alon Levy RH-Acked-by: Hans de Goede Add support for the spice tablet interface. The tablet interface will be registered (and then used by the spice client) as soon as a absolute pointing device is available and used by the guest, i.e. you'll have to configure your guest with '-usbdevice tablet'. upstream: 869564a9c0f78b1972e1ac51e69cb2016af3b060 Signed-off-by: Gerd Hoffmann --- ui/spice-display.c | 2 +- ui/spice-input.c | 94 ++++++++++++++++++++++++++++++++++++++++++++++++---- 2 files changed, 88 insertions(+), 8 deletions(-) Signed-off-by: Luiz Capitulino --- ui/spice-display.c | 2 +- ui/spice-input.c | 94 ++++++++++++++++++++++++++++++++++++++++++++++++---- 2 files changed, 88 insertions(+), 8 deletions(-) diff --git a/ui/spice-display.c b/ui/spice-display.c index 0bc230e..6702dfd 100644 --- a/ui/spice-display.c +++ b/ui/spice-display.c @@ -180,7 +180,7 @@ void qemu_spice_create_host_primary(SimpleSpiceDisplay *ssd) surface.width = ds_get_width(ssd->ds); surface.height = ds_get_height(ssd->ds); surface.stride = -surface.width * 4; - surface.mouse_mode = 0; + surface.mouse_mode = true; surface.flags = 0; surface.type = 0; surface.mem = (intptr_t)ssd->buf; diff --git a/ui/spice-input.c b/ui/spice-input.c index 91cf18d..37c8578 100644 --- a/ui/spice-input.c +++ b/ui/spice-input.c @@ -17,6 +17,7 @@ #include #include +#include #include #include @@ -76,9 +77,13 @@ static void kbd_leds(void *opaque, int ledstate) /* mouse bits */ -typedef struct QemuSpiceMouse { - SpiceMouseInstance sin; -} QemuSpiceMouse; +typedef struct QemuSpicePointer { + SpiceMouseInstance mouse; + SpiceTabletInstance tablet; + int width, height, x, y; + Notifier mouse_mode; + bool absolute; +} QemuSpicePointer; static int map_buttons(int spice_buttons) { @@ -121,17 +126,92 @@ static const SpiceMouseInterface mouse_interface = { .buttons = mouse_buttons, }; +static void tablet_set_logical_size(SpiceTabletInstance* sin, int width, int height) +{ + QemuSpicePointer *pointer = container_of(sin, QemuSpicePointer, tablet); + + if (height < 16) { + height = 16; + } + if (width < 16) { + width = 16; + } + pointer->width = width; + pointer->height = height; +} + +static void tablet_position(SpiceTabletInstance* sin, int x, int y, + uint32_t buttons_state) +{ + QemuSpicePointer *pointer = container_of(sin, QemuSpicePointer, tablet); + + pointer->x = x * 0x7FFF / (pointer->width - 1); + pointer->y = y * 0x7FFF / (pointer->height - 1); + kbd_mouse_event(pointer->x, pointer->y, 0, map_buttons(buttons_state)); +} + + +static void tablet_wheel(SpiceTabletInstance* sin, int wheel, + uint32_t buttons_state) +{ + QemuSpicePointer *pointer = container_of(sin, QemuSpicePointer, tablet); + + kbd_mouse_event(pointer->x, pointer->y, wheel, map_buttons(buttons_state)); +} + +static void tablet_buttons(SpiceTabletInstance *sin, + uint32_t buttons_state) +{ + QemuSpicePointer *pointer = container_of(sin, QemuSpicePointer, tablet); + + kbd_mouse_event(pointer->x, pointer->y, 0, map_buttons(buttons_state)); +} + +static const SpiceTabletInterface tablet_interface = { + .base.type = SPICE_INTERFACE_TABLET, + .base.description = "tablet", + .base.major_version = SPICE_INTERFACE_TABLET_MAJOR, + .base.minor_version = SPICE_INTERFACE_TABLET_MINOR, + .set_logical_size = tablet_set_logical_size, + .position = tablet_position, + .wheel = tablet_wheel, + .buttons = tablet_buttons, +}; + +static void mouse_mode_notifier(Notifier *notifier) +{ + QemuSpicePointer *pointer = container_of(notifier, QemuSpicePointer, mouse_mode); + bool is_absolute = kbd_mouse_is_absolute(); + + if (pointer->absolute == is_absolute) { + return; + } + + if (is_absolute) { + qemu_spice_add_interface(&pointer->tablet.base); + } else { + spice_server_remove_interface(&pointer->tablet.base); + } + pointer->absolute = is_absolute; +} + void qemu_spice_input_init(void) { QemuSpiceKbd *kbd; - QemuSpiceMouse *mouse; + QemuSpicePointer *pointer; kbd = qemu_mallocz(sizeof(*kbd)); kbd->sin.base.sif = &kbd_interface.base; qemu_spice_add_interface(&kbd->sin.base); qemu_add_led_event_handler(kbd_leds, kbd); - mouse = qemu_mallocz(sizeof(*mouse)); - mouse->sin.base.sif = &mouse_interface.base; - qemu_spice_add_interface(&mouse->sin.base); + pointer = qemu_mallocz(sizeof(*pointer)); + pointer->mouse.base.sif = &mouse_interface.base; + pointer->tablet.base.sif = &tablet_interface.base; + qemu_spice_add_interface(&pointer->mouse.base); + + pointer->absolute = false; + pointer->mouse_mode.notify = mouse_mode_notifier; + qemu_add_mouse_mode_change_notifier(&pointer->mouse_mode); + mouse_mode_notifier(&pointer->mouse_mode); } -- 1.7.4.rc1.16.gd2f15e
