How to do that with CPPI? + * + * - RX queues in "rndis" mode -- one single BD -- handle (a) correctly, but + * (b) loses **BADLY** because nothing (!) happens when that second packet + * fills the buffer, much less when a third one arrives. (Which makes this + * not a "true" RNDIS mode. In the RNDIS protocol short-packet termination + * is optional, and it's fine if peripherals -- not hosts! -- pad messages + * out to end-of-buffer. Standard PCI host controller DMA descriptors + * implement that mode by default ... which is no accident.) + * + * - RX queues in "transparent" mode -- two BDs with 512 bytes each -- have + * converse problems: (b) is handled right, but (a) loses badly.

Those products integrate the Inventra logic + * with other DMA, IRQ, and bus modules, as well as other logic that + * needs to be reflected in this driver. + * + * + * NOTE: the original Mentor code here was pretty much a collection + * of mechanisms that don't seem to have been fully integrated/working + * for *any* Linux kernel version. This version aims at Linux 2.6.now, + * Key open issues include: + * + * - Lack of host-side transaction scheduling, for all transfer types. + * The hardware doesn't do it; instead, software must. + * + * This is not an issue for OTG devices that don't support external + * hubs, but for more "normal" USB hosts it's a user issue that the + * "multipoint" support doesn't scale in the expected ways. That + * includes DaVinci EVM in a common non-OTG mode. + * + * * Control and bulk use dedicated endpoints, and there's as + * yet no mechanism to either (a) reclaim the hardware when + * peripherals are NAKing, which gets complicated with bulk + * endpoints, or (b) use more than a single bulk endpoint in + * each direction. + * + * RESULT: one device may be perceived as blocking another one. + * + * * Interrupt and isochronous will dynamically allocate endpoint + * hardware, but (a) there's no record keeping for bandwidth; + * (b) in the common case that few endpoints are available, there + * is no mechanism to reuse endpoints to talk to multiple devices. + * + * RESULT: At one extreme, bandwidth can be overcommitted in + * some hardware configurations, no faults will be reported. + * At the other extreme, the bandwidth capabilities which do + * exist tend to be severely undercommitted.
