- Add support for GET REPORT. Allows OS to get a single input report.
- Add support for SET_IDLE. Allows OS to control when to send input reports
The SET IDLE and the underlying logic change fixes several things:
- The old issue of congestion in some systems.
- The new bug that would not allow setup packets to be received because mode
was set to only send when there are changes.
- Now this starts properly as the old code but allows to be changed by OS on
demand, while continuing servicing setup packets.
The default interrupt moderation on XUSB controller was causing 4.62ms latency, hurting performance tremendously, especially in smaller usb packets (which are the norm).
This change brings it to parity with USB2 controller.
- Rework all timeouts to be more relaxed when doing big data transfers.
- Fix a bug where async transfer would timeout sooner instead of infinite tries.
Both showed up in Arch Linux, because of it's huge latency USB stack latency that can reach 1-2s.
The rework will let every OS work without adding additional wait time in the gadget loops.
