Hi Deepesh, Thanks for the new version. While it runs correctly on the autobuilder, I'm noting it takes quite a bit of time to run the tests. I'm not really against merging them, I just want: - to make everybody aware of that. - to confirm with you these are some expected timings. Taking some random build in my branch: 2026-03-03 21:20:21,805 - oe-selftest - INFO - clang.LLDSelfTestSystemEmulated.test_lld (subunit.RemotedTestCase) 2026-03-03 21:20:21,805 - oe-selftest - INFO - ... ok 2026-03-03 21:20:21,805 - oe-selftest - INFO - 2: 1/1 18/21 (7205.57s) (0 failed) (clang.LLDSelfTestSystemEmulated.test_lld) ... 2026-03-04 00:56:44,671 - oe-selftest - INFO - clang.ClangSelfTestSystemEmulated.test_clang (subunit.RemotedTestCase) 2026-03-04 00:56:44,671 - oe-selftest - INFO - ... ok 2026-03-04 00:56:44,671 - oe-selftest - INFO - 1: 1/1 20/21 (20188.43s) (0 failed) (clang.ClangSelfTestSystemEmulated.test_clang) 2026-03-04 01:37:34,036 - oe-selftest - INFO - clang.LLVMSelfTestSystemEmulated.test_llvm (subunit.RemotedTestCase) 2026-03-04 01:37:34,036 - oe-selftest - INFO - ... ok 2026-03-04 01:37:34,036 - oe-selftest - INFO - 3: 1/1 21/21 (22637.80s) (0 failed) (clang.LLVMSelfTestSystemEmulated.test_llvm) https://autobuilder.yoctoproject.org/valkyrie/#/builders/5/builds/3230 So first, we only had a few builds so far, maybe we just were a bit unlucky (looking at the test, I believe sstate will not have any impact in later builds). Also we already had some quite long tests in there, but in some builds the test_clang / test_llvm really seems to take a longer time.
