Subject: [PATCH v5 0/6] CXL core reorganization
Date: Mon, 02 Aug 2021 10:29:33 -0700 [thread overview]
Message-ID: <162792537312.368511.15862521152871631343.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
Changes since v4 [1]:
- Fix ARCH=um compile errors reported by 0day caused by header
filename collisions with "mem.h", moved to "cxlmem.h"
- Improve kdoc note for @fops attribute of 'struct
cdevm_file_operations' (Jonathan)
- Include core.h in memdev.c to fix "no prior declaration" warnings
(kbuild robot)
- Collect reviewed-by's from Jonathan

Original Cover from Ben:
The main motivation of the patch series is to establish the cxl_core driver in
its own directory and modularize it. Specifically, the patch series aims to
achieve three things:
1. Move existing core functionality to a new directory.
2. Split existing core functionality into multiple files.
3. Migrate memdev functionality into core.
#1 is trivially accomplished with git mv. The file itself is renamed back to
bus.c since the goal is to break up core functionality into multiple files, and
so the name core.c doesn't make sense in that context.
#2 is also trivially accomplished via cut/paste.
#3 is slightly invasive in that it has certain functional changes to improve the
existing interfaces and make them more generic. The rest of the change is
cut/paste. This is also the only part of the series which has runtime functional
change in that some interfaces are removed from cxl_pci, moved into cxl_core,
and exported for other drivers to use.
