2024-02-22hw/input/pckbd: Open-code i8042_setup_a20_line() wrapperPhilippe Mathieu-Daudé
Since the named GPIO lines are a "public" interface to the device, we can directly call qdev_connect_gpio_out_named(), making it consistent with how the other A20 input source (port92) is wired.

2024-02-14hw/virtio: Move vhost-user-input into virtio folderLeo Yan
vhost-user-input is in the input folder. On the other hand, the folder 'hw/virtio' maintains other virtio stubs (e.g. I2C, RNG, GPIO, etc). This patch moves vhost-user-input into the virtio folder for better code organization. No functionality change.

2023-11-02hw/input/stellaris_gamepad: Convert to qemu_input_handler_register()Peter Maydell
Now that we have converted to qdev, we can use the newer qemu_input_handler_register() API rather than the legacy qemu_add_kbd_event_handler(). Since we only have one user, take the opportunity to convert from scancodes to QCodes, rather than using qemu_input_key_value_to_scancode() (which adds an 0xe0 prefix and encodes up/down indication in the scancode, which our old handler function then had to reverse). That lets us drop the old state field which was tracking whether we were halfway through a two-byte scancode.

2023-11-02hw/input/stellaris_gamepad: Remove StellarisGamepadButton structPeter Maydell
Currently for each button on the device we have a StellarisGamepadButton struct which has the irq, keycode and pressed state for it. When we convert to qdev, the qdev property and GPIO APIs are going to require that we have separate arrays for the irqs and keycodes. Convert from array-of-structs to three separate arrays in preparation. This is a migration compatibility break for the stellaris boards (lm3s6965evb, lm3s811evb).

Reportedly, real hardware does not send a key release scancode. So, skip sending a release for these keys.

2022-12-16Replace use of qdev_reset_all() with device_cold_reset()Peter Maydell
The legacy function qdev_reset_all() performs a recursive reset, starting from a qdev. However, it does not permit any of the devices in the tree to use three-phase reset, because device reset goes through the device_legacy_reset() function that only calls the single DeviceClass::reset method. Switch to using the device_cold_reset() function instead. This also performs a recursive reset, where first the children are reset and then finally the parent, but it uses the new (...in 2020...) Resettable mechanism, which supports both the old style single-reset method and also the new 3-phase reset handling. This commit changes the five remaining uses of this function.

2022-07-18lasips2: update VMStateDescription for LASIPS2 deviceMark Cave-Ayland
Since this series has already introduced a migration break for the HPPA B160L machine, we can use this opportunity to improve the VMStateDescription for the LASIPS2 device. Add the new int_status field to the VMStateDescription and remodel the ports as separate VMSTATE_STRUCT instances representing each LASIPS2Port. Once this is done, the migration stream can be updated to include buf and loopback_rbne for each port (which is necessary since the values are accessed across separate IO accesses), and drop the port id as this is hardcoded for each port type.

2022-07-18lasips2: switch to using port-based IRQsMark Cave-Ayland
Now we can implement port-based IRQs by wiring the PS2 device IRQs to the LASI2Port named input gpios rather than directly to the LASIPS2 device, and generate the LASIPS2 output IRQ from the int_status bitmap representing the individual port IRQs instead of the birq boolean. This enables us to remove the separate PS2 keyboard and PS2 mouse named input gpios from the LASIPS2 device and simplify the register implementation to drive the port IRQ using qemu_set_irq() rather than accessing the LASIPS2 device IRQs directly. As a consequence the IRQ level logic in lasips2_set_irq() can also be simplified accordingly. For now this patch ignores adding the int_status bitmap and simply drops the birq boolean from the vmstate_lasips2 VMStateDescription. This is because the migration stream is already missing some required LASIPS2 fields, and as this series already introduces a migration break for the lasips2 device it is easiest to fix this in a follow-up patch.
