Joe Damato says: ==================== ena: Link IRQs, queues, and NAPI instances This series uses the netdev-genl API to link IRQs and queues to NAPI IDs so that this information is queryable by user apps. This is particularly useful for epoll-based busy polling apps which rely on having access to the NAPI ID. I've tested these commits on an EC2 instance with an ENA NIC configured and have included test output in the commit messages for each patch showing how to query the information. I noted in the implementation that the driver requests an IRQ for management purposes which does not have an associated NAPI. I tried to take this into account in patch 1, but would appreciate if ENA maintainers can verify I did this correctly. v1: https://lore.kernel.org/all/20240930195617.37369-1-jdamato@fastly.com/ ==================== Link: https://patch.msgid.link/20241002001331.65444-1-jdamato@fastly.com Signed-off-by: Jakub Kicinski <kuba@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 reStructuredText 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.
