Subject: [PATCH 0/2] Remove cxl and cxlflash drivers
Date: Tue, 10 Dec 2024 18:27:18 +1100 [thread overview]
Message-ID: <20241210072721.157323-1-ajd@linux.ibm.com> (raw)
This series removes the cxl and cxlflash drivers for IBM CAPI devices.
CAPI devices have been out of production for some time, and we're not
aware of any remaining users who are likely to want a modern kernel.
There's almost certainly some remaining driver bugs and we don't have much
hardware available to properly test the drivers any more. Removing these
drivers will also mean we can get rid of a non-trivial amount of support
code in arch/powerpc.
Thanks to everyone who's worked on these drivers over the last decade.
This series applies on top of [0].
