On top of this, the usage of MODULE_ALIAS makes possible to add a new reset module without being obliged to update the framework. The new implementation relies on the reset module registering its reset function to the vfio-platform driver. The series is available at https://git.linaro.org/people/eric.auger/linux.git/shortlog/refs/heads/v4.3-rc6-rework-v2 Best Regards Eric v1 -> v2: * in vfio_platform_common.c: - move reset lookup at load time and put reset at release: this is to prevent a race between the 2 load module loads - reset_list becomes static - vfio_platform_register/unregister_reset take a const char * as compat - fix node link - remove old combo struct and cleanup proto of vfio_platform_get_reset - add mutex to protect the reset list * in calxeda xgmac reset module - introduce vfio_platform_reset_private.h - use module_vfio_reset_handler macro - do not export vfio_platform_calxedaxgmac_reset symbol anymore - add a pr_info to show the device is reset by vfio reset module Eric Auger (6): vfio: platform: add capability to register a reset function vfio: platform: reset: add vfio_platform_reset_private.h vfio: platform: reset: calxedaxgmac: add reset function registration vfio: platform: add compat in vfio_platform_device vfio: platform: use list of registered reset function vfio: platform: move get/put reset at open/release drivers/vfio/platform/reset/Makefile | 2 +- .../platform/reset/vfio_platform_calxedaxgmac.c | 9 +- .../platform/reset/vfio_platform_reset_private.h | 66 +++++++++ drivers/vfio/platform/vfio_platform_common.c | 151 ++++++++++++++++----- drivers/vfio/platform/vfio_platform_private.h | 15 +- 5 files changed, 201 insertions(+), 42 deletions(-) create mode 100644 drivers/vfio/platform/reset/vfio_platform_reset_private.h -- 1.9.1
