- Allow 'isolated PCI functions' (multi-function devices without a function 0) for LoongArch, similar to s390 and jailhouse (Huacai Chen) - Mask out unrelated bits in PCIE_LNKCAP_SLS2SPEED() and PCIE_LNKCTL2_TLS2SPEED(), which makes them more robust and fixes a WARN_ON_ONCE() in pcie_set_target_speed() (Jiwei Sun) - Read Link Control 2 again when retraining a link after a training failure so we try to increase the link speed (Jiwei Sun) - Allow built-in drivers, not just modular drivers, to use async initial probing (Lukas Wunner) - Support Immediate Readiness even on devices with no PM Capability (Sean Christopherson) * pci/enumeration: PCI: Support Immediate Readiness on devices without PM capabilities PCI: Allow built-in drivers to use async initial probing PCI: Adjust the position of reading the Link Control 2 register PCI: Fix link speed calculation on retrain failure PCI: Extend isolated function probing to LoongArch
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.
