* Instead of passing the flags as part of a struct that's supposed to bepatrick2020-03-211-2/+1

* Switch USB to use non-coherent buffers for data transfers. Sincepatrick2020-03-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the import in '99 all buffers allocated using usb_allocmem() have been mapped COHERENT. On some ARM SoCs, where the USB controller is not coherent with the caches, this means the buffers were mapped uncached. This drastically reduces the performance, especially on reads. We already added cache syncs before and after USB transfers, but so far those have essentially been no-ops. Since other drivers make use of the same allocation code, and those haven't been proven to have correct syncs, we can't just remove the COHERENT flag. This splits the allocation into coherent and non-coherent blocks. All drivers who call usb_allocmem() themselves now pass a flag to show they require coherent blocks. Onced verified that they also work fine without coherent, or once they have been refactored, we can remove this again. On a ure(4) connected to an i.MX8MQ, the receive performance is 10x as fast as before. The Raspberry Pi's ethernet receive speed doubled.

* Simplify/refactor the way vendor/product/serial informations arelandry2018-05-011-3/+1
| | | | | | | | | | | | | | | | | | gathered from usb devices. Cache them early in usbd_new_device() instead of querying the device several times (the content wont change anyway) and uselessly generating usb traffic (which could conflict with other access..) The heuristic stays the same, first look in the device descriptor, then try to match against usb_known_vendors/usb_known_products, then fallback to use the idVendor/idProduct codes. Remove the now useless 'usedev' parameter from usbd_fill_deviceinfo(). Tested from bsd & bsd.rd. suggested by and ok mpi@
