SubjectRe: PCI DMA to small buffers on cache-incoherent arch
From

If I understand both Davids correctly this is the solution.
Buffers for dma must be allocated seperately using a special allocation
function which is given the device so it can allocate correctly.
David B wants a bus specific pointer to a function in the generic
driver structure, right ?

Eventually it could be exactly that, via the generic driver struct.

For now it can be a usb specific thing, and when the generic device
stuff is ready we just go:

#define usb_pool_alloc(...) dev_pool_alloc(...)

without having to touch any of the driver call sites.
