Try running ``./tools/testing/kunit/kunit.py run`` with the ``--raw_output`` + parameter. This might show details or error messages hidden by the kunit_tool + parser. +2. Instead of running ``kunit.py run``, try running ``kunit.py config``, + ``kunit.py build``, and ``kunit.py exec`` independently. This can help track + down where an issue is occurring. (If you think the parser is at fault, you + can run it manually against stdin or a file with ``kunit.py parse``.) +3. Running the UML kernel directly can often reveal issues or error messages + kunit_tool ignores. This should be as simple as running ``./vmlinux`` after + building the UML kernel (e.g., by using ``kunit.py build``). Note that UML + has some unusual requirements (such as the host having a tmpfs filesystem + mounted), and has had issues in the past when built statically and the host + has KASLR enabled. (On older host kernels, you may need to run ``setarch + `uname -m` -R ./vmlinux`` to disable KASLR.) +4. Make sure the kernel .config has ``CONFIG_KUNIT=y`` and at least one test + (e.g. ``CONFIG_KUNIT_EXAMPLE_TEST=y``). kunit_tool will keep its .config + around, so you can see what config was used after running ``kunit.py run``. + It also preserves any config changes you might make, so you can + enable/disable things with ``make ARCH=um menuconfig`` or similar, and then + re-run kunit_tool. +5. Try to run ``make ARCH=um defconfig`` before running ``kunit.py run``. This + may help clean up any residual config items which could be causing problems. +6. Finally, try running KUnit outside UML. KUnit and KUnit tests can run be + built into any kernel, or can be built as a module and loaded at runtime. + Doing so should allow you to determine if UML is causing the issue you're + seeing. When tests are built-in, they will execute when the kernel boots, and + modules will automatically execute associated tests when loaded. Test results + can be collected from ``/sys/kernel/debug/kunit/<test suite>/results``, and + can be parsed with ``kunit.py parse``. For more details, see "KUnit on + non-UML architectures" in :doc:`usage`. + +If none of the above tricks help, you are always welcome to email any issues to +kunit-dev@googlegroups.com. diff --git a/Documentation/devicetree/bindings/Makefile b/Documentation/devicetree/bindings/Makefile index a63898954068..91c4d00e96d3 100644 --- a/Documentation/devicetree/bindings/Makefile +++ b/Documentation/devicetree/bindings/Makefile @@ -2,7 +2,6 @@ DT_DOC_CHECKER ?= dt-doc-validate DT_EXTRACT_EX ?= dt-extract-example DT_MK_SCHEMA ?= dt-mk-schema -DT_MK_SCHEMA_USERONLY_FLAG := $(if $(DT_SCHEMA_FILES), -u) DT_SCHEMA_MIN_VERSION = 2020.5 @@ -35,21 +34,40 @@ quiet_cmd_mk_schema = SCHEMA $@ DT_DOCS = $(shell $(find_cmd) | sed -e 's|^$(srctree)/||') -DT_SCHEMA_FILES ?= $(DT_DOCS) - -extra-$(CHECK_DT_BINDING) += $(patsubst $(src)/%.yaml,%.example.dts, $(DT_SCHEMA_FILES)) -extra-$(CHECK_DT_BINDING) += $(patsubst $(src)/%.yaml,%.example.dt.yaml, $(DT_SCHEMA_FILES)) -extra-$(CHECK_DT_BINDING) += processed-schema-examples.yaml - override DTC_FLAGS := \ -Wno-avoid_unnecessary_addr_size \ - -Wno-graph_child_address + -Wno-graph_child_address \ + -Wno-interrupt_provider $(obj)/processed-schema-examples.yaml: $(DT_DOCS) check_dtschema_version FORCE $(call if_changed,mk_schema) -$(obj)/processed-schema.yaml: DT_MK_SCHEMA_FLAGS := $(DT_MK_SCHEMA_USERONLY_FLAG) +ifeq ($(DT_SCHEMA_FILES),) + +# Unless DT_SCHEMA_FILES is specified, use the full schema for dtbs_check too. +# Just copy processed-schema-examples.yaml + +$(obj)/processed-schema.yaml: $(obj)/processed-schema-examples.yaml FORCE + $(call if_changed,copy) + +DT_SCHEMA_FILES = $(DT_DOCS) + +else + +# If DT_SCHEMA_FILES is specified, use it for processed-schema.yaml + +$(obj)/processed-schema.yaml: DT_MK_SCHEMA_FLAGS := -u $(obj)/processed-schema.yaml: $(DT_SCHEMA_FILES) check_dtschema_version FORCE $(call if_changed,mk_schema) -extra-y += processed-schema.yaml +endif + +extra-$(CHECK_DT_BINDING) += $(patsubst $(src)/%.yaml,%.example.dts, $(DT_SCHEMA_FILES)) +extra-$(CHECK_DT_BINDING) += $(patsubst $(src)/%.yaml,%.example.dt.yaml, $(DT_SCHEMA_FILES)) +extra-$(CHECK_DT_BINDING) += processed-schema-examples.yaml +extra-$(CHECK_DTBS) += processed-schema.yaml + +# Hack: avoid 'Argument list too long' error for 'make clean'.
