The old version device driver can use the reserved memory and OS memory. But the new version can only use OS memory (Mandatory requirements in the driver code). What is the reason why the new version driver gave up reserved memory?
That's a very old GPU, so I'm surprised there even is a new driver. What platform (device / OS) is this for? Generally drivers come from silicon or device providers, rather than from Arm, so this may be a question for others.
hello, I found the driver on this website: utgard-kernel. It is suitable for Linux OS.
