From stress testing of arecord, we found that period size greater than ~900 will bring pl330 to DYING state and can not recover within 100 iterations. The result is that arecord will stuck and get I/O error, and issue can not be recovered until reboot. This issue does not happen when period size is small. Set constraint of period size to 240 to prevent such issue. With the constraint, there will be no issue after 2000 iterations. We can revert this patch once the root cause is found in rockchip's pl330 implementation.

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.
