Hello David,
I have to use Linux kernel version 2.4.1 for my sh architecture.
So I have tried to apply your patchs to it. First I have added to
usb-ohci.c file hcca allocation with pci_alloc_consistent (I don't
know if this is a correct procedure but ,in this way, patchs application
doesn'give any fails).
But for my architecture there is a problem with pci_alloc_consistent:
void *pci_alloc_consistent(struct pci_dev *hwdev, size_t size,
dma_addr_t * dma_handle)
{
void *ret;
int gfp = GFP_ATOMIC;
printk("BUG: pci_alloc_consistent() called - not yet
supported\n");
/* We ALWAYS need DMA memory on the overdrive hardware,
* due to it's extreme wierdness
* Need to flush the cache here as well, since the memory
* can still be seen through the cache!
*/
gfp |= GFP_DMA;
ret = (void *) __get_free_pages(gfp, get_order(size));
if (ret != NULL) {
memset(ret, 0, size);
*dma_handle = virt_to_bus(ret);
}
return ret;
}
When I run I get:
