From 5e1bdc12bd298a9751da4285b7e93c68b1314332 Mon Sep 17 00:00:00 2001 From: salmonik Date: Tue, 4 Aug 2026 03:06:06 +0200 Subject: v0.5.10: USB HID mouse via polled xHCI (rsnix/src/usb.rs) Polled xHCI driver (mouse-only): controller bring-up, port reset, enable-slot -> address-device -> config-descriptor walk -> HID boot mouse IN endpoint, one outstanding IN TRB drained on poll. Cursor task polls usb first, PS/2 second. New 'usb'/'usb rescan' shell cmds. Verified in QEMU (q35 + OVMF + qemu-xhci + usb-mouse): movement and all three buttons tracked exactly; heap stays clean. Fixes en route: MaxPorts=HCSPARAMS1[31:24]; operational regs CRCR=0x18 DCBAAP=0x30 CONFIG=0x38; pass input-context ptr in Address-Device; Input Control Context DW0=Drop DW1=Add; HID walker bInterfaceClass at +5; async discovery from cursor task. --- rsnix/src/lib.rs | 1 + 1 file changed, 1 insertion(+) (limited to 'rsnix/src/lib.rs') diff --git a/rsnix/src/lib.rs b/rsnix/src/lib.rs index dbb327c..bc2553d 100644 --- a/rsnix/src/lib.rs +++ b/rsnix/src/lib.rs @@ -17,6 +17,7 @@ pub mod pci; pub mod qr; pub mod power; pub mod ps2; +pub mod usb; pub mod rtc; pub mod sched; pub mod serial; -- cgit v1.2.3
