Hi David!
Differences in this version:
In patch 1:
- itd_complete() split into 3 functions, assures schedule is updated
before ITD is recycled and lets
- updates to ehci->periodic_sched happen per urb again
- SITD handling unchanged. Didn't find anything to improve.
New patches 2 & 3
- Reduce dma-memory usage by slimming struct ehci_itd.
On x86_64 patch 1 makes ehci_itd grow 1 32byte alignment step,
patch 2 & 3 let ehci_itd take 1 32byte alignment less each.
kind regards,
Karsten
