[PATCH 4/4] usb: xhci: add endpoint context tracing when an endpoint is added

The configure endpoint command configures all the endpoints that were flagged to be added or dropped. To know the content of each of the added endpoints we need to add tracing to the .add_endpoint() callback, just after initializing all the context values. Signed-off-by: Mathias Nyman --- drive

[PATCH 1/4] usb: xhci: add Immediate Data Transfer support

From: Nicolas Saenz Julienne Immediate data transfers (IDT) allow the HCD to copy small chunks of data (up to 8bytes) directly into its output transfer TRBs. This avoids the somewhat expensive DMA mappings that are performed by default on most URBs submissions. In the case an URB was suitable fo

[PATCH 0/4] xhci features for usb-next

Hi Greg A few features for usb next, mostly tracing and debugging features, but also support for Immediate Data Transfer for small (up to 8 bytes) data transfers -Mathias Mathias Nyman (3): xhci: add port and bus number to port dynamic debugging xhci: Add tracing for input control context

[PATCH 3/4] xhci: Add tracing for input control context

Add tracing for the add and drop bits in the input control context used in Address device, configure endpoint, evaluate context commands. The add and drop bits tell xHC which enpoints are added and dropped. Signed-off-by: Mathias Nyman --- drivers/usb/host/xhci-trace.h | 25
