From f9c481247f6a2c87439e0ebfa42cd56325db2ac0 Mon Sep 17 00:00:00 2001 From: Katsuhiro Ueno Date: Tue, 27 Apr 2021 11:02:46 +0900 Subject: hw/input/hid: Add support for keys of jp106 keyboard. Add support for the following keys: KATAKANAHIRAGANA, HENKAN, MUHENKAN, RO, and YEN. Before this commit, these keys did not work as expected when a jp106 keyboard was connected to the guest as a usb-kbd device.

We should have checked the level to determine whether the interrupt needs to be delivered. The level check logic was present in early versions of the xhci model, but got dropped later by a rework of interrupt handling under commit 4c4abe7cc903 ("xhci: rework interrupt handling").

Currently QEMU does not clear the IP flag in the MSI / MSI-X mode. This causes subsequent spurious interrupt to be delivered to guests. To solve this, we change the xhci intr_raise() hook routine to have a bool return value that is passed to its caller (the xhci core), with true indicating that IP should be self-cleared.
