[ Upstream commit 0a723ed3baa941ca4f51d87bab00661f41142835 ] Currently, the transfer polling interval is set to 1ms, which is the frame rate of full-speed and low-speed USB. The USB 2.0 specification introduces microframes (125 microseconds) to improve the timing precision of data transfers. Reducing the transfer interval to 1 microframe increases data throughput for high-speed and super-speed USB communication Signed-off-by: Marcello Sylvester Bauer <marcello.bauer@9elements.com> Signed-off-by: Marcello Sylvester Bauer <sylv@sylv.io> Link: https://lore.kernel.org/r/6295dbb84ca76884551df9eb157cce569377a22c.1712843963.git.sylv@sylv.io Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@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.
