Radeon in kernel in risc-v

Hello,
I add some debug information to the radeon-source-code of linux-kernel,then I rebuild kernel and update kernel(the compiled driver is called A, and the original driver is called B )
①If I  add the radeon/CAICOS_xx.bin to CONFIG_EXTRA_FIRMWARE in.config file ,during kernel startup, the radeon driver executed is B, and the display-monitor can be bright。
①If kept CONFIG_EXTRA_FIRMWARE  empty ,during kernel startup, the radeon driver executed is A, and the display-monitor is not bright。

 

why?
