Is Mali-400 MP GPU Technical Overview/Technical Reference Manual document free to get? If it is, but how could I get it?

onion

Hi, all

I have had an access to infocenter.arm.com, but I got nothing but place-holder for Mali-400 MP GPU Technical Overview/TRM.

I wonder if those document is free to get. And what does it take to get them?

Best Regards,

Michael

    Hi Firefly,

    There's nothing public that I'm aware of that describes the actual function/meaning of anything in the kernel code, besides what is released with that code or the comments in it.

    The kernel driver never touches an instance of _mali_io_address, it just passes pointers to instances of them around, so it's not necessary to define the type in the kernel module itself. I think this is either a handle returned by the kernel, or a mechanism to pass something from userspace to the hardware, one or the other.

    Hope this helps,

    Chris
