| |
I have written a driver which, in part, facilitates the usb bulk transfer of raw image data. It works fine for small (CIF, QCIF) images, but for larger images, kmalloc will not allocate enough memory.
I copied the rvmalloc code from the cpia2 driver and used it in place of kmalloc. The memory allocates fine, but usb_bulk_msg now times out when using the pointer to the rvmalloc'd memory. I have been unable to find an instance of an existing driver using rvmalloc in conjunction with usb_bulk_msg.
Thanks in advance for any advice. Please reply via email - I am not subscribed to the mailing list.
