- Judge each TRB has been handled at cdns3_trb_handled, since the DMA pointer may be at the middle of the TD, we can't consider this TD has finished at that time. - Calculate req->actual according to finished TRBs. - Handle short transfer for sg list use case correctly. When the short transfer occurs, we check OUT_SMM at TRB to see if it is the last TRB. Signed-off-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
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.
