Gabor Juhos 1809db75bd interconnect: increase ICC_DYN_ID_START Since commit `d30f83d278` ("interconnect: core: Add dynamic id allocation support"), interconnect node ids greater than or equal to ICC_DYN_ID_START are reserved for dynamic id allocation. Yet the icc_node_create_nolock() function allows to directly use such ids for creating nodes. This can cause problems by executing dynamic id related codepaths even for nodes intended to use static ids. For example, the 'nsscc-ipq9574' driver creates interconnect nodes with static ids starting from 19148. Because these ids belongs to the dynamic id range, the icc_node_add() function replaces the node names unexpectedly. The node names looked like this before the change: # grep nss_cc /sys/kernel/debug/interconnect/interconnect_summary nss_cc_nssnoc_ppe_clk_master 0 0 nss_cc_nssnoc_ppe_clk_slave 0 0 nss_cc_nssnoc_ppe_cfg_clk_master 0 0 ... And those have an unexpected suffix now: # grep nss_cc /sys/kernel/debug/interconnect/interconnect_summary nss_cc_nssnoc_ppe_clk_master@39b00000.clock-controller 0 0 nss_cc_nssnoc_ppe_clk_slave@39b00000.clock-controller 0 0 nss_cc_nssnoc_ppe_cfg_clk_master@39b00000.clock-controller 0 0 ... Increase the value of ICC_DYN_ID_START to avoid this. Also, add sanity check to the icc_node_create_nolock() function to prevent directly creating nodes with ids reserved for dynamic allocation in order to detect these kind of problems.

README

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.
