Re: Firmware Loading every boot?

[Jeshwanth Kumar N K <jeshkumar555@xxxxxxxxx>]

Hi Arun,

Thanks for the reply :)

Which means all the firmware available in /lib/firmware loads to device when device attached? (I mean to volatile memory of device)

I have one more doubt/assumption in this.

What I feel is, dynamically loading firmware is because of loading the firmware for specific platform. i.e. Windows and Linux firmware (for same device) are different, Windows loads firmware which is created for Windows, and Linux loads firmware created for Linux systems.

Please let me know whether my assumption is right :)

Hello List,

I came to know that, linux loads firmware for my dma everytime it boots.
But I don't understand, why it is required to load everytime it boots, don't dma holds which is loaded previously.

Might be because it is loaded in to some volatile memory like DDR, which does not persist during reboots.

Thanks,

Arun

 

AFAIK, firmware is a program which runs in devices.

Please correct me if I am wrong. 

Thanks :)
