- Document sysfs "irq" attribute, which contains either the INTx IRQ (the intended behavior) or the first MSI IRQ (historical mistake retained for backwards compatibility) (Barry Song) - Rework "irq" sysfs show function to explicitly fetch first MSI IRQ instead of depending on core to put it in dev->irq, to enable future core cleanup (Barry Song) * pci/msi: PCI/sysfs: Explicitly show first MSI IRQ for 'irq' PCI: Document /sys/bus/pci/devices/.../irq
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.
