What? No, no no.
You must not use pa() on immap addresses. All you did was convert
a proper address to some bogus one, you are writing over some other
part of memory that is eventually going to cause a failure. The immap
addresses are identity mapped virtual to physical.
There isn't any performance problem with this driver if your hardware
is working properly. I cant' believe this change would have done
anything except eventually causing the system to fail.
What kernel are you using?
Thanks.
