fpga: region: add compat_id support

2018-07-15T11:55:44Z

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

2018-07-15T11:55:44Z

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. Signed-off-by: Wu Hao Acked-by: Alan Tull Signed-off-by: Greg Kroah-Hartman

fpga: mgr: add status for fpga-manager

2018-07-15T11:55:44Z

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

2018-07-15T11:55:44Z

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. Signed-off-by: Wu Hao Acked-by: Moritz Fischer Acked-by: Alan Tull Signed-off-by: Greg Kroah-Hartman

fpga: use SPDX

fpga: region: change api, add fpga_region_create/free

2018-05-25T16:23:56Z

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.

fpga: bridge: change api, don't use drvdata

2018-05-25T16:23:55Z

Change fpga_bridge_register to not set drvdata. This is to support the case where a PCIe device can have more than one bridge. Add API functions to create/free the fpga bridge struct. Change fpga_bridge_register/unregister to take FPGA bridge struct as the only parameter. struct fpga_bridge *fpga_bridge_create(struct device *dev, const char *name, const struct fpga_bridge_ops *br_ops, void *priv); void fpga_bridge_free(struct fpga_bridge *br); int fpga_bridge_register(struct fpga_bridge *br); void fpga_bridge_unregister(struct fpga_bridge *br); Update the drivers that call fpga_bridge_register with the new API.

fpga: manager: change api, don't use drvdata

2018-05-25T16:23:55Z

Change fpga_mgr_register to not set or use drvdata. This supports the case where a PCIe device has more than one manager. Add fpga_mgr_create/free functions. Change fpga_mgr_register and fpga_mgr_unregister functions to take the mgr struct as their only parameter. struct fpga_manager *fpga_mgr_create(struct device *dev, const char *name, const struct fpga_manager_ops *mops, void *priv); void fpga_mgr_free(struct fpga_manager *mgr); int fpga_mgr_register(struct fpga_manager *mgr); void fpga_mgr_unregister(struct fpga_manager *mgr); Update the drivers that call fpga_mgr_register with the new API.

fpga: add attribute groups

2017-11-28T15:30:38Z

Make it easy to add attributes to low level FPGA drivers the right way. Add attribute groups pointers to structures that are used when registering a manager, bridge, or group. When the low level driver registers, set the device attribute group. The attributes are created in device_add. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman
