[PATCH] Documentation: pm: fix duplicate hyperlink target errors

[Swaraj Gaikwad]

Fix reST warnings in
Documentation/admin-guide/pm/intel_pstate.rst caused by missing explicit
hyperlink labels for section titles.

Before this change, the following errors were printed during
`make htmldocs`:

  Documentation/admin-guide/pm/intel_pstate.rst:401:
    ERROR: Indirect hyperlink target (id="id6") refers to target
    "passive mode", which is a duplicate, and cannot be used as a
    unique reference.
  Documentation/admin-guide/pm/intel_pstate.rst:517:
    ERROR: Indirect hyperlink target (id="id9") refers to target
    "active mode", which is a duplicate, and cannot be used as a
    unique reference.
  Documentation/admin-guide/pm/intel_pstate.rst:611:
    ERROR: Indirect hyperlink target (id="id15") refers to target
    "global attributes", which is a duplicate, and cannot be used as
    a unique reference.
  ERROR: Duplicate target name, cannot be used as a unique reference:
  "passive mode", "active mode", "global attributes".

These errors occurred because the sections "Active Mode",
"Active Mode With HWP", "Passive Mode", and "Global Attributes"
did not define explicit hyperlink labels. As a result, Sphinx
auto-generated duplicate anchors when the same titles appeared
multiple times within the document.

Because of this, the generated HTML documentation contained
broken references such as:

  `active mode <Active Mode_>`_
  `passive mode <Passive Mode_>`_
  `global attributes <Global Attributes_>`_

This patch adds explicit hyperlink labels for the affected sections,
ensuring all references are unique and correctly resolved.

After applying this patch, `make htmldocs` completes without
any warnings, and all hyperlinks in intel_pstate.html render properly.

Hmm... I don't see these warnings when I build htmldocs by:

  $ make SPHINXOPTS='-j 1' htmldocs

My environment uses docutils 0.21.2 and Sphinx 8.2.3, though. What are yours?

Applied as 6.19 material, thanks!

Re: [PATCH] Documentation: pm: fix duplicate hyperlink target errors

[Swaraj Gaikwad]

Hi Bagas,

Thanks for reviewing!

Here are the versions from my environment where the warnings appear:

  sphinx-build 8.2.3
  Docutils 0.22.2, Python 3.13.7, on linux)

So it seems the issue shows up with docutils 0.22.2 but not with 0.21.2.

Thanks again for confirming the diff looks good!

Best regards,
Swaraj
