Thanks for doing this Marc! I'm wondering about the need to delineate between what is needed to load and use the cxl-test or nfit-test modules as opposed to what is required to run all the unit tests. I believe my environment, and yours, and most other folks using these environments are doing so in a VM so it's no big deal to load up all the things. Maybe just a gentle separator in the list showing required and optional. I would NOT go so far as to pick apart which ones are needed for which test because that is a slippery slope. If a user is in test running mode they need all the things. > > Link: > https://lore.kernel.org/nvdimm/aed71134-1029-4b88-ab20-8dfa527a7...@linux.intel.com/ > Signed-off-by: Marc Herbert <marc.herb...@linux.intel.com> > --- > README.md | 10 ++++++++++ > 1 file changed, 10 insertions(+) > > diff --git a/README.md b/README.md > index db25a9114402..a37991ccefa2 100644 > --- a/README.md > +++ b/README.md > @@ -69,10 +69,20 @@ loaded.
