Hi Takashi,

Removing FW_LOADER_USER_HELPER_FALLBACK leads to a failure in our HQVDP firmware execution. Indeed, our firmware is not built-in. It is a proprietary firmware uploaded into the file system that's why we need the USER_HELPER_FALLBACK to be able to load it once file system is available.

Hmm most other DRM drivers also require firmware. Whist some allow the firmware to be picked in initrd it's not a strict requirement. So I'm wondering how come there hasn't been (m)any reports, considering that neither one sets USER_HELPER_FALLBACK.

Perhaps they also need it, or something in the sti module is done differently ? Just some food for thought.
