commit 69ea463021be0d159ab30f96195fb0dd18ee2272 upstream. When using "devm_request_threaded_irq(,,,,IRQF_ONESHOT,,)" in a driver, only the first interrupt is handled, and following interrupts are never delivered (initially reported in [1]). That's because the RISC-V PLIC cannot EOI masked interrupts, as explained in the description of Interrupt Completion in the PLIC spec [2]: <quote> The PLIC signals it has completed executing an interrupt handler by writing the interrupt ID it received from the claim to the claim/complete register. The PLIC does not check whether the completion ID is the same as the last claim ID for that target. If the completion ID does not match an interrupt source that *is currently enabled* for the target, the completion is silently ignored. </quote> Re-enable the interrupt before completion if it has been masked during the handling, and remask it afterwards.

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.
