Improve debugging by adding and unifying messages whenever a decoder was added to a port. It is especially useful to get the decoder mapping of the involved CXL host bridge or PCI device. This avoids a complex lookup of the decoder/port/device mappings in sysfs. Example log messages: cxl_acpi ACPI0017:00: decoder0.0 added to root0 cxl_acpi ACPI0017:00: decoder0.1 added to root0 ... pci0000:e0: decoder1.0 added to port1 pci0000:e0: decoder1.1 added to port1 ... cxl_mem mem0: decoder5.0 added to endpoint5 cxl_mem mem0: decoder5.1 added to endpoint5 Signed-off-by: Robert Richter <rrichter@amd.com> Reviewed-by: Gregory Price <gourry@gourry.net> Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Dave Jiang <dave.jiang@intel.com> Reviewed-by: Alison Schofield <alison.schofield@intel.com> Tested-by: Gregory Price <gourry@gourry.net> Acked-by: Dan Williams <dan.j.williams@intel.com> Link: https://patch.msgid.link/20250509150700.2817697-15-rrichter@amd.com Signed-off-by: Dave Jiang <dave.jiang@intel.com> |

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.
