* [PATCH v2] scripts/dtc: dt_to_config - kernel config options for a devicetree @ 2016-06-10 23:01 Frank Rowand [not found] ` <575B46CE.6080903-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> 0 siblings, 1 reply; 11+ messages in thread From: Frank Rowand @ 2016-06-10 23:01 UTC (permalink / raw) To: Rob Herring, gaurav.minocha.os-Re5JQEeQqe8AvxtiuMwx3w Cc: grant.likely-QSEj5FYQhm4dnm+yROfE0A, devicetree-u79uwXL29TY76Z2rM5mHXA, geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ, pavel-+ZI9xUNit7I From: Frank Rowand <frank.rowand-mEdOJwZ7QcZBDgjK7y7TUQ@public.gmane.org> Determining which kernel config options need to be enabled for a given devicetree can be a painful process. Create a new tool to find the drivers that may match a devicetree node compatible, find the kernel config options that enable the driver, and optionally report whether the kernel config option is enabled. Signed-off-by: Gaurav Minocha <gaurav.minocha.os-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> Signed-off-by: Frank Rowand <frank.rowand-mEdOJwZ7QcZBDgjK7y7TUQ@public.gmane.org> --- changes from v1 - Add --config-format to create config fragment that can be appended to kernel .config - Add short node path option, default to full node path for --config-format - Add options to use the driver black list, the config white list, and the driver white list (new default is to ignore) - Remove need to hard code config options for hard coded driver. This allowed removal of 8 entries from the hard coded config list. - Remove virt/kvm/arm/.* from driver black list (not needed after commit 503a62862e8f in 4.7-rc1) - Remove fixed-partitions from compatibles white list - Updated the --help message - Remove non-ascii copyright symbol scripts/dtc/dt_to_config | 1213 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 1213 insertions(+) Index: b/scripts/dtc/dt_to_config =================================================================== --- /dev/null +++ b/scripts/dtc/dt_to_config @@ -0,0 +1,1213 @@ +#!/usr/bin/perl + +# Copyright 2016 by Frank Rowand +# Copyright 2016 by Gaurav Minocha +# +# This file is subject to the terms and conditions of the GNU General Public +# License v2. + +use strict 'refs'; +use strict subs; + +use Getopt::Long; + +$VUFX = "160610a"; + +$script_name = $0; +$script_name =~ s|^.*/||; + + +# ----- constants for print_flags() + +# Position in string $pr_flags.

This program must be run in the root directory of a Linux kernel source tree. The default format is a report that is intended to be easily human scannable. An alternate format can be selected by --config-format. This will create output that can easily be edited to create a fragment that can be appended to the existing kernel config file. Each entry consists of multiple lines. The first line reports flags, the node path, compatible value, driver file matching the compatible, configuration options, and current values of the configuration options. For each configuration option, the following lines report the current value and the value that is required for the driver file to be included in the kernel. If a large number of drivers or config options is listed for a node, and the 'H' flag is set consider using --white-list-config and/or --white-list-driver. If the white list option suppresses the correct entry please report that as a bug. CAUTION: This program uses heuristics to guess which driver(s) support each compatible string and which config option(s) enables the driver(s). Do not believe that the reported information is fully correct. This program is intended to aid the process of determining the proper kernel configuration for a device tree, but this is not a fully automated process -- human involvement may still be required! The driver match heuristic used is to search for source files containing the compatible string enclosed in quotes. This program might not be able to find all drivers matching a compatible string. Some makefiles are overly clever. This program was not made complex enough to handle them. If no config option is listed for a driver, look at the makefile for the driver source file. Even if a config option is listed for a driver, some other available config options may not be listed. FLAG values: M multiple compatibles found for this node d driver found for this compatible D multiple drivers found for this compatible c kernel config found for this driver C multiple config options found for this driver E node is not enabled W compatible is white listed H matching driver and/or kernel config is hard coded x kernel config hard coded in Makefile n one or more kernel config file options is not set m one or more kernel config file options is set to 'm' y one or more kernel config file options is set to 'y' F one of more kernel config file options fails to have correct value Upper case letters indicate potential issues or problems. The flag: H matching driver and/or kernel config is hard coded will be set if the config or driver is in the white lists, even if --white-list-config and --white-list-driver are not specified. This is a hint that 1) many of these reported lines are likely to be incorrect, and 2) using those options will reduce the number of drivers and/or config options reported. --white-list-config and --white-list-driver may not be accurate if this program is not well maintained. Use them with appropriate skepticism. Use the --show-lists option to report the values in the list.

Are you in the root directory of a kernel tree? The answer to the first question is no, and I'm not going to add it. If I'm in the kernel root, then the script should know where to find it. Rob P.S. There is this new tool called git and its sub command git-format-patch. It has some nifty features like setting the file mode, so the maintainer doesn't have to. And it enables doing a 3-way merge when applying patches that don't apply cleanly. ;) -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 11+ messages in thread
