For us would be better if we manage to use it through the driver. Until now, from this thread I think there are two scenarios: When there's a device, through ufs-bsg: - ufs-utils: using the current ufs_bsg interface will have the capability to cover most of the scenarios that I can think of and will be the standard way to interact with the ufs driver. During bring up/debug without link to device: - My proposal is to create a debugFS interface: uic-cmd/ ├── dme-get ├── dme-set ├── dme-enable ├── dme-reset └── ... test-feature/ ├── PA_tf └── ... error-dump/ ├── UECPA ├── UECDL └── ... ... I kindly request the ecosystem feedback. Thanks, Pedro
