| | | | | | | | | | | | | | | | | nvgpu_mem_rd*() functions were implemented per OS. They also used nvgpu_pramin_access_batched() and implemented a big portion of logic for using PRAMIN in OS specific code. Make the implementation for the functions generic. Move all PRAMIN logic to PRAMIN and simplify the interface provided by PRAMIN.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_submit_channel_gpfifo the gpfifo entries can come from a kernel buffer or from userspace. To simplify the logic in gk20a_submit_append_gpfifo, extract out a function that copies the entries directly from userspace to the gpu memory for performance, and another function that copies from a kernel buffer to the gpu memory. The latter is used for kernel submits and when the gpfifo pipe exists which would mean that the gpfifo memory is in vidmem and is thus not directly accessible with a kernel virtual pointer. While this function is being changed a lot, also rename it to start with nvgpu_ instead of gk20a_. Additionally, simplify pushbuffer debug tracing by always using the kernel memory for the prints. Tracing when the gpfifo memory has been allocated in vidmem is no longer supported; sysmem is almost always used in practice anyway.
