The keyboard sends reports which have room for up to six + * normal keys and all standard modifier keys. A report always reflects the + * current state of the keyboard and indicates which keys are held down. + * + * Software normally utilizes the keyboard's interrupt endpoint to request + * reports to be sent whenever a state change occurs. However, reports can + * also be sent whenever an interrupt transfer is initiated (the keyboard is + * not "idle") or requested via the control endpoint (polling). + * + * Because turnaround on USB is relatively slow, the keyboard often ends up + * in a situation where new input arrived but there is no URB available + * where a report could be written to. The PDM queue maintained by the + * keyboard driver is utilized to provide buffering and hold incoming events + * until they can be passed along. The USB keyboard can effectively buffer + * up to one event. + * + * If there is a pending event and a new URB becomes available, a report is + * built and the keyboard queue is flushed. This ensures that queued events + * are processed as quickly as possible. + * + * A second interface with its own interrupt endpoint is used to deliver + * additional key events for media and system control keys. This adds + * considerable complexity to the emulated device, but unfortunately the + * keyboard boot interface is fixed and fairly limited. + * + * The second interface is only exposed if the device is configured in + * "extended" mode, with a different USB product ID and different + * descriptors. The "basic" mode should be indistinguishable from the original + * implementation. + * + * There are various options available for reporting media keys. We chose + * a very basic approach which reports system control keys as a bit-field + * (since there are only 3 keys defined) and consumer control keys as just + * a single 16-bit value. + * + * As a consequence, only one consumer control key can be reported as + * pressed at any one time. While this may seem limiting, the usefulness of + * being able to report e.g. volume-up at the same time as volume-down or + * mute is highly questionable. + * + * System control and consumer control keys are reported in a single + * 4-byte report in order to avoid sending multiple separate report types. + * + * There is a slight complication in that both interfaces are configured + * together, but a guest does not necessarily "listen" on both (e.g. EFI). + * Since all events come through a single queue, we can't just push back + * events for the secondary interface because the entire keyboard would be + * blocked. After the device is reset/configured, we drop any events destined + * for the secondary interface until a URB is actually queued on the second + * interrupt endpoint. Once that happens, we assume the guest will be + * receiving data on the second endpoint until the next reset/reconfig. + * + * References: + * + * Device Class Definition for Human Interface Devices (HID), Version 1.11 + * + */ + + +/********************************************************************************************************************************* +* Header Files * +*********************************************************************************************************************************/ +#define LOG_GROUP LOG_GROUP_USB_KBD +#include <VBox/vmm/pdmusb.h> +#include <VBox/log.h> +#include <VBox/err.h> +#include <iprt/assert.h> +#include <iprt/critsect.h> +#include <iprt/mem.h> +#include <iprt/semaphore.h> +#include <iprt/string.h> +#include <iprt/uuid.h> +#include "VBoxDD.h" + + +/********************************************************************************************************************************* +* Defined Constants And Macros * +*********************************************************************************************************************************/ +/** @name USB HID string IDs + * @{ */ +#define USBHID_STR_ID_MANUFACTURER 1 +#define USBHID_STR_ID_PRODUCT 2 +#define USBHID_STR_ID_IF_KBD 3 +#define USBHID_STR_ID_IF_EXT 4 +/** @} */ + +/** @name USB HID specific descriptor types + * @{ */ +#define DT_IF_HID_DESCRIPTOR 0x21 +#define DT_IF_HID_REPORT 0x22 +/** @} */ + +/** @name USB HID vendor and product IDs + * @{ */ +#define VBOX_USB_VENDOR 0x80EE +#define USBHID_PID_BAS_KEYBOARD 0x0010 +#define USBHID_PID_EXT_KEYBOARD 0x0011 +/** @} */ + +/** @name USB HID class specific requests + * @{ */ +#define HID_REQ_GET_REPORT 0x01 +#define HID_REQ_GET_IDLE 0x02 +#define HID_REQ_SET_REPORT 0x09 +#define HID_REQ_SET_IDLE 0x0A +/** @} */ + +/** @name USB HID additional constants + * @{ */ +/** The highest USB usage code reported by the VBox emulated keyboard */ +#define VBOX_USB_MAX_USAGE_CODE 0xE7 +/** The size of an array needed to store all USB usage codes */ +#define VBOX_USB_USAGE_ARRAY_SIZE (VBOX_USB_MAX_USAGE_CODE + 1) +#define USBHID_USAGE_ROLL_OVER 1 +/** The usage code of the first modifier key. */ +#define USBHID_MODIFIER_FIRST 0xE0 +/** The usage code of the last modifier key. */ +#define USBHID_MODIFIER_LAST 0xE7 +/** @} */ + + +/********************************************************************************************************************************* +* Structures and Typedefs * +*********************************************************************************************************************************/ + +/** + * The device mode. + */ +typedef enum USBKBDMODE +{ + /** Basic keyboard only, backward compatible. */ + USBKBDMODE_BASIC = 0, + /** Extended 2nd interface for consumer control and power. */ + USBKBDMODE_EXTENDED, +} USBKBDMODE;
