An attempt was made to add capi support for the Mellanox CX4 card, so
that it could operate in "traditional" PCI mode or capi mode. The
project ended up being canceled and a different approach was taken for
CX5. Mellanox never upstreamed any capi support in their CX4 driver.
CX4 was not following exactly the CAIA 1.0 model, so some CX4-specific
code was added. That code is now dead and hasn't been tested for a
while, so it's probably broken anyway. Let's remove it. It has been
agreed with engineers at Mellanox, of course.
No user API is affected. Some (unused) symbols exported by cxl are removed.
Most of the patch set consists of reverts of older patches, with
sometimes very minor tweaking. The last patch aggregates a few changes
where reverting was not possible easily.
Tests run to prevent regressions:
- memcpy tests on POWER8 and POWER9
- Mellanox CX5, which uses a different code path, based on cxllib
- cxlflash tests on POWER8
9 of these commits are missing Signed-off-bys.
git revert -s is a thing :)
