b1992c37 - kbuild: use $(src) instead of $(srctree)/$(src) for source directory

Sat, 27 Apr 2024 14:55:02 +0000

kbuild: use $(src) instead of $(srctree)/$(src) for source directoryKbuild conventionally uses $(obj)/ for generated files, and $(src)/ forchecked-in source files. It is merely a convention without any functionaldifference. In fact, $(obj) and $(src) are exactly the same, as definedin scripts/Makefile.build: src := $(obj)When the kernel is built in a separate output directory, $(src) doesnot accurately reflect the source directory location. While Kbuildresolves this discrepancy by specifying VPATH=$(srctree) to search forsource files, it does not cover all cases. For example, when adding aheader search path for local headers, -I$(srctree)/$(src) is typicallypassed to the compiler.This introduces inconsistency between upstream and downstream Makefilesbecause $(src) is used instead of $(srctree)/$(src) for the latter.To address this inconsistency, this commit changes the semantics of$(src) so that it always points to the directory in the source tree.Going forward, the variables used in Makefiles will have the followingmeanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source treeConsequently, $(srctree)/$(src) in upstream Makefiles need to be replacedwith $(src).Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux-6.15/Documentation/devicetree/bindings/Makefile

604a57ba - dt-bindings: kbuild: Add separate target/dependency for processed-schema.json

Fri, 05 Apr 2024 22:56:03 +0000

dt-bindings: kbuild: Add separate target/dependency for processed-schema.jsonRunning dtbs_check and dt_compatible_check targets really only dependon processed-schema.json, but the dependency is 'dt_binding_check'. Thatwas sort worked around with the CHECK_DT_BINDING variable in order toskip some of the work that 'dt_binding_check' does. It still runs thefull checks of the schemas which is not necessary and adds 10s ofseconds to the build time. That's significant when checking only a fewDTBs and with recent changes that have improved the validation time by6-7x.Add a new target, dt_binding_schema, which just buildsprocessed-schema.json and can be used as the dependency for othertargets. The scripts_dtc dependency isn't needed either as the examplesaren't built for it.Signed-off-by: Rob Herring Tested-by: Conor Dooley Signed-off-by: Masahiro Yamada List of files: /linux-6.15/Documentation/devicetree/bindings/Makefile

Fri, 05 Apr 2024 22:56:02 +0000

dt-bindings: kbuild: Split targets out to separate rulesMasahiro pointed out the use of if_changed_rule is incorrect and commandline changes are not correctly accounted for.To fix this, split up the DT binding validation target,dt_binding_check, into multiple rules for each step: yamllint, schemavalidtion with meta-schema, and building the processed schema.One change in behavior is the yamllint or schema validation will bere-run again when there are warnings present.Reported-by: Masahiro Yamada Link: https://lore.kernel.org/all/20220817152027.16928-1-masahiroy@kernel.org/Signed-off-by: Rob Herring Signed-off-by: Masahiro Yamada List of files: /linux-6.15/Documentation/devicetree/bindings/Makefile

5e3ef454 - dt-bindings: ignore paths outside kernel for DT_SCHEMA_FILES

Wed, 20 Dec 2023 14:55:37 +0000

dt-bindings: ignore paths outside kernel for DT_SCHEMA_FILESIf the location of the kernel sources contains the string that we'refiltering for using DT_SCHEMA_FILES, then all schemas will currently bematched, returned and checked, not just the ones we actually expected.As an example, if the kernel sources happen to be below a directory'google', and DT_SCHEMA_FILES=google, everything is checked. Morecommon examples might be having the sources below people's homedirectories that contain the string st or arm and then searching forthose. The list is endless.Fix this by only matching for schemas below the kernel source'sbindings directory.Note that I opted for the implementation here so as to not having todeal with escaping DT_SCHEMA_FILES, which would have been thealternative if the grep match itself had been updated.Cc: Masahiro Yamada Signed-off-by: André Draszik Link: https://lore.kernel.org/r/20231220145537.2163811-1-andre.draszik@linaro.orgSigned-off-by: Rob Herring List of files: /linux-6.15/Documentation/devicetree/bindings/Makefile

dt-bindings: Drop kernel copy of common reserved-memory bindingsThe common reserved-memory bindings have recently been copied from thekernel tree into dtschema. The preference is to host common, stablebindings in dtschema. As reserved-memory is documented in the DT Spec,it meets the criteria.The v2023.09 version of dtschema is what contains the reserved-memoryschemas we depend on, so bump the minimum version to that.

ef8795f3 - dt-bindings: kbuild: Use DTB files for validation

Thu, 10 Mar 2022 16:05:13 +0000

dt-bindings: kbuild: Use DTB files for validationSwitch the DT validation to use DTB files directly instead of a DTS toYAML conversion.The original motivation for supporting validation on DTB files was toenable running validation on a running system (e.g. 'dt-validate/sys/firmware/fdt') or other cases where the original source DTS is notavailable.The YAML format was not without issues. Using DTBs with the schema typeinformation solves some of those problems. The YAML format relies on theDTS source level information including bracketing of properties, sizedirectives, and phandle tags all of which are lost in a DTB file. Whilestandardizing the bracketing is a good thing, it does cause a lot ofextra warnings and churn to fix them.Another issue has been signed types are not validated correctly as signinformation is not propagated to YAML. Using the schema type informationallows for proper handling of signed types. YAML also can't representthe full range of 64-bit integers as numbers are stored as floats bymost/all parsers.The DTB validation works by decoding property values using the typeinformation in the schemas themselves. The main corner case this doesnot work for is matrix types where neither dimension is fixed. Fornow, checking the dimensions in these cases are skipped.Signed-off-by: Rob Herring Tested-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20220310160513.1708182-3-robh@kernel.org List of files: /linux-6.15/Documentation/devicetree/bindings/Makefile
