As with an adapter, some aspects of initialisation are done only once in the lifetime of an AFU: for example, allocating memory, or setting up sysfs/debugfs files. However, we may want to be able to do some parts of the initialisation multiple times: for example, in error recovery we want to be able to tear down and then re-map IO memory and IRQs. Therefore, refactor AFU init/teardown as follows. - Create two new functions: 'cxl_configure_afu', and its pair 'cxl_deconfigure_afu'. As with the adapter functions, these (de)configure resources that do not need to last the entire lifetime of the AFU. - Allocating and releasing memory remain the task of 'cxl_alloc_afu' and 'cxl_release_afu'. - Once-only functions that do not involve allocating/releasing memory stay in the overarching 'cxl_init_afu'/'cxl_remove_afu' pair. However, the task of picking an AFU mode and activating it has been broken out. Signed-off-by: Daniel Axtens <dja@axtens.net> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |
