+meta-mixins-lts - wrynose/go
+============================
+
+"Mixin" layer for adding latest Go toolchain versions into the Yocto Project LTS.
+
+At the time Wrynose was released in April 2026, Go 1.26 was the latest version
+and officially Wrynose supports only that. This thin special-purpose mixin
+layer is meant to address this issue by backporting Go recipes from the master
+branch of openembedded-core.
+
+Dependencies
+------------
+
+This layer depends on:
+
+- URI: git://github.com/openembedded/openembedded-core.git  
+  layers: meta  
+  branch: wrynose
+
+Contributing
+------------
+
+The patches can be backported from openembedded-core with:
+
+ git -C ../openembedded-core format-patch --stdout -1 origin/master meta/recipes-devtools/go | \
+ git am --signoff -p4 --directory=recipes-devtools/go
+
+The yocto-patches mailinglist (yocto-patches@lists.yoctoproject.org) is used
+for questions, comments and patch review. It is subscriber only, so please
+register before posting.
+
+Send pull requests to yocto-patches@lists.yoctoproject.org with
+'[meta-lts-mixins][wrynose/go]' in the subject.
+
+When sending single patches, please use something like:
+git send-email -M -1 --to=yocto-patches@lists.yoctoproject.org --subject-prefix='meta-lts-mixins][wrynose/go][PATCH'

+
+Quality Assurance
+-----------------
+
+QA tests are using original openembedded-core testsuites.
+Current plan is to backport QA test changes to openembedded-core wrynose branch.
+When that is no longer possible, changes will picked here.
+
+Automated tests to verify go toolchain functionality are being executed with following configurations and commands:
+
+* OEQA runtime
+
+    ```
+    IMAGE_INSTALL:append = " cgo-helloworld go-helloworld packagegroup-go-sdk-target"
+    IMAGE_CLASSES += "testimage"
+    TEST_SUITES:append = " go go_mixin"
+    ```
+
+    ```
+    bitbake core-image-ptest-go && bitbake core-image-ptest-go:do_testimage
+    ```
+
+* OEQA SDK
+
+    ```
+    IMAGE_CLASSES += "testimage"
+    SDK_TOOLCHAIN_LANGS = "go"
+    TESTSDK_SUITES = "go"
+    ```
+
+    ```
+    bitbake core-image-minimal:do_populate_sdk && bitbake core-image-minimal:do_testsdk
+    ```
+
+* OEQA selftest
+
+    ```
+    SANITY_TESTED_DISTROS = ""
+    ```
+
+    ```
+    oe-selftest -r gotoolchain -j $(grep -c ^processor /proc/cpuinfo)
+    ```
