Insert a padding between data and the stored_xfer_buffer pointer to ensure they are not on the same cache line. Otherwise, the stored_xfer_buffer gets corrupted for IN URBs on non-cache-coherent systems. (In my case: Lantiq xRX200 MIPS) Fixes: 3bc04e28a030 ("usb: dwc2: host: Get aligned DMA in a more supported way") Fixes: 56406e017a88 ("usb: dwc2: Fix DMA alignment to start at allocated boundary") Cc: <stable@vger.kernel.org> Tested-by: Douglas Anderson <dianders@chromium.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Acked-by: Minas Harutyunyan <hminas@synopsys.com> Signed-off-by: Martin Schiller <ms@dev.tdt.de> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
