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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
