Previously when running perf trace timehist --state, when recording processes in the zombie state the process name would not be decoded properly and appears with just the PID: 1140057.412177 [0006] Mutter Input Th[3139/3104] 0.956 0.019 0.041 S 1140057.412222 [0012] :1248612[1248612] 0.000 0.000 0.332 Z 1140057.412275 [0004] <idle> 0.052 0.052 0.953 I 1140057.412284 [0008] <idle> 0.070 0.070 0.932 I 1140057.412333 [0004] KMS thread[3126/3104] 0.953 0.112 0.058 S Now some extra processing has been added to decode the process name: 1140057.412177 [0006] Mutter Input Th[3139/3104] 0.956 0.019 0.041 S 1140057.412222 [0012] sleep[1248612] 0.000 0.000 0.332 Z 1140057.412275 [0004] <idle> 0.052 0.052 0.953 I 1140057.412284 [0008] <idle> 0.070 0.070 0.932 I 1140057.412333 [0004] KMS thread[3126/3104] 0.953 0.112 0.058 S Signed-off-by: Anubhav Shelat <ashelat@redhat.com> Link: https://lore.kernel.org/r/20250716203914.45772-2-ashelat@redhat.com Signed-off-by: Namhyung Kim <namhyung@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
