linux-toradex.git/Documentation/admin-guide/tainted-kernels.rst, branch v5.16-rc5 Linux kernel for Apalis and Colibri modules docs: Update documentation to reflect what TAINT_CPU_OUT_OF_SPEC means 2020-12-08T17:53:58+00:00 Mathieu Chouquet-Stringer me@mathieu.digital 2020-12-02T15:32:43+00:00 547f574fd9d5e3925d47fd44decbf6ab6df94b0e Here's a patch updating the meaning of TAINT_CPU_OUT_OF_SPEC after Borislav introduced changes in a7e1f67ed29f and upcoming patches in tip. TAINT_CPU_OUT_OF_SPEC now means a bit more what it implies as the flag isn't set just because of a CPU misconfiguration or mismatch. Historically it was for SMP kernel oops on an officially SMP incapable processor but now it also covers CPUs whose MSRs have been incorrectly poked at from userspace, drivers being used on non supported architectures, broken firmware, mismatched CPUs, ... Update documentation and script to reflect that.

Here's a patch updating the meaning of TAINT_CPU_OUT_OF_SPEC after
Borislav introduced changes in a7e1f67ed29f and upcoming patches in tip.

TAINT_CPU_OUT_OF_SPEC now means a bit more what it implies as the
flag isn't set just because of a CPU misconfiguration or mismatch.
Historically it was for SMP kernel oops on an officially SMP incapable
processor but now it also covers CPUs whose MSRs have been incorrectly
poked at from userspace, drivers being used on non supported
architectures, broken firmware, mismatched CPUs, ...

Update documentation and script to reflect that.

docs: Revamp tainted-kernels.rst to make it more comprehensible 2019-01-08T23:33:47+00:00 Thorsten Leemhuis linux@leemhuis.info 2019-01-08T19:40:07+00:00 896dd323abbf6a9980d8aca2656b6c4bf5352c3b Add a section about decoding /proc/sys/kernel/tainted, create a more understandable intro and a hopefully explain better the tainted flags in bugs, oops or panics messages. Only thing missing then is a table that quickly describes the various bits and taint flags before going into more detail, so add that as well. That table is partly based on a section from Documentation/sysctl/kernel.txt, but a bit more compact. To avoid confusion I added the shortened version to kernel.txt; the same table is used in three different places now: ./tools/debugging/kernel-chktaint, Documentation/admin-guide/tainted-kernels.rst and Documentation/sysctl/kernel.txt During review of v1 (see above) a number of existing issues with the text were raised, like outdated usages as well as incomplete or missing descriptions.
