If anyone has any objections, please let me know. ------------------ From: Lucas Stach [ Upstream commit 1006d1f7c03d92b28c252333836635df8e165401 ] While the FE is an important part of the GPU, which needs to be idle after reset, all other modules should be idle after a proper reset. Check all present modules for being idle to determine whether the reset was successful.
