This allows external drivers to utilise the core of the generic OpenCAPI driver to communicate with specific OpenCAPI hardware. Changelog: V2: - Reorder patches as some required structs that were only available later - Add dev.release implementation for ocxl_file_info to address warning on driver unload (ocxl: Create a clear delineation...) - Set output var irq_id in ocxl_afu_irq_alloc (ocxl: afu_irq only deals...) - Bump copyright year (ocxl: Provide global MMIO accessors..., ocxl: Split pci.c) Alastair D'Silva (7): ocxl: Split pci.c ocxl: Don't pass pci_dev around ocxl: Create a clear delineation between ocxl backend & frontend ocxl: Allow external drivers to use OpenCAPI contexts ocxl: afu_irq only deals with IRQ IDs, not offsets ocxl: move event_fd handling to frontend ocxl: Provide global MMIO accessors for external drivers drivers/misc/ocxl/Makefile | 3 +- drivers/misc/ocxl/afu_irq.c | 97 ++--- drivers/misc/ocxl/context.c | 18 +- drivers/misc/ocxl/core.c | 578 ++++++++++++++++++++++++++++++ drivers/misc/ocxl/file.c | 160 ++++++--- 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, 1390 insertions(+), 703 deletions(-) create mode 100644 drivers/misc/ocxl/core.c create mode 100644 drivers/misc/ocxl/mmio.c -- 2.20.1
