Ji Alex,
OK.
As I am going to touch at traces,
- are you OK if I use the new .name field to simply format strings?
DPRINTF("%s(%04x:%02x:%02x.%x) Pin %c\n", __func__, vdev->host.domain,
vdev->host.bus, vdev->host.slot, vdev->host.function,
'A' + vdev->intx.pin);
- Also Alex was suggesting to use trace points. What is your position
about that? Also I am not 100% sure of what it consists in? is it trace
events as documented in docs/tracing.txt
Thanks
Eric
