Subject: [PATCH 0/3] cxl/test: mock fixups and new topology support
Date: Mon, 28 Sep 2026 17:56:15 -0700	[thread overview]
Message-ID: <cover.1790641236.git.alison.schofield@intel.com> (raw)

While working to enhance the cxl-cli cxl-create-region command to handle
out-of-order target lists or no user-supplied target list, I ran into some
basic issues in the existing command that need to be addressed first.
Developing tests for those fixes exposed two bugs and a topology gap in
the cxl_test mock module.

This cxl_test series addresses those issues:

1/3 fixes a DPA skip leak across mock decoder reset.
2/3 skips auto-region setup when no volatile window is active.
3/3 adds two x1 CFMWS windows needed to exercise root decoder selection.

A companion ndctl series will fix the existing cxl-create-region issues
in cxl-cli, clearing the way for out-of-order or automatically generated
target lists.

These changes preserve the existing cxl_test unit test behavior while
enabling new create-region test cases.
