From: Alastair D'Silva <alast...@d-silva.org> This series reworks the OpenCAPI driver to split frontend (driver interactions) from backend (hardware interactions).
This allows external drivers to utilise the core of the generic OpenCAPI driver to communicate with specific OpenCAPI hardware. Alastair D'Silva (7): ocxl: Provide global MMIO accessors for external drivers ocxl: Allow external drivers to use OpenCAPI contexts ocxl: Split pci.c ocxl: Don't pass pci_dev around ocxl: Create a clear delineation between ocxl backend & frontend ocxl: afu_irq only deals with IRQ IDs, not offsets ocxl: move event_fd handling to frontend drivers/misc/ocxl/Makefile | 3 +- drivers/misc/ocxl/afu_irq.c | 94 ++--- drivers/misc/ocxl/context.c | 18 +- drivers/misc/ocxl/core.c | 578 ++++++++++++++++++++++++++++++ drivers/misc/ocxl/file.c | 157 +++++--- drivers/misc/ocxl/mmio.c | 234 ++++++++++++ drivers/misc/ocxl/ocxl_internal.h | 49 +-- drivers/misc/ocxl/pci.c | 562 ++--------------------------- drivers/misc/ocxl/sysfs.c | 58 +-- drivers/misc/ocxl/trace.h | 12 +- include/misc/ocxl.h | 322 ++++++++++++++++- 11 files changed, 1382 insertions(+), 705 deletions(-) create mode 100644 drivers/misc/ocxl/core.c create mode 100644 drivers/misc/ocxl/mmio.c -- 2.20.1
