fpga: region: add compat_id support

2018-07-15T11:55:44+00:00

This patch introduces a compat_id pointer member and sysfs interface
for each fpga region, similar as compat_id for fpga manager, it allows
applications to read the per region compat_id for compatibility
checking before other actions on this fpga-region (e.g. PR).

fpga: mgr: add compat_id support

2018-07-15T11:55:44+00:00

This patch introduces compat_id support to fpga manager, it adds
a fpga_compat_id pointer to fpga manager data structure to allow
fpga manager drivers to save the compatibility id. This compat_id
could be used for compatibility checking before doing partial
reconfiguration to associated fpga regions.

fpga: mgr: add status for fpga-manager

2018-07-15T11:55:44+00:00

This patch adds status sysfs interface for fpga manager, it's a
read only interface which allows user to get fpga manager status,
including full/partial reconfiguration error and other status
information. It adds a status callback to fpga_manager_ops too,
allows each fpga_manager driver to define its own method to
collect latest status from hardware.

The following sysfs file is created:
* /sys/class/fpga_manager//status
  Return status of fpga manager, including reconfiguration errors.

fpga: mgr: add region_id to fpga_image_info

2018-07-15T11:55:44+00:00

This patch adds region_id to fpga_image_info data structure, it
allows driver to pass region id information to fpga-mgr via
fpga_image_info for fpga reconfiguration function.

fpga: region: change api, add fpga_region_create/free

2018-05-25T16:23:56+00:00

Add fpga_region_create/free API functions.

Change fpga_region_register to take FPGA region struct as the only
parameter.  Change fpga_region_unregister to return void.

  struct fpga_region *fpga_region_create(struct device *dev,
                        struct fpga_manager *mgr,
                        int (*get_bridges)(struct fpga_region *));
  void fpga_region_free(struct fpga_region *region);
  int fpga_region_register(struct fpga_region *region);
  void fpga_region_unregister(struct fpga_region *region);

Remove groups storage from struct fpga_region, it's not
needed.  Callers can just "region->dev.groups = groups;"
after calling fpga_region_create.

Update the drivers that call fpga_region_register with the new API.
