Along the same lines as rewriting the polaris code, this rewrites the fiji code, and reduces the driver size by ~40k. Signed-off-by:

This removes the init path as well, since the init path just did some constant init of some structs. Reviewed-by:

These don't seem to change at runtime, and the initialisers are constant data. This could be improved by not selecting the apu/non-apu path on each pcie read/write access. Signed-off-by:

This isn't safe if we have multiple GPUs plugged in, since there is only one copy of this struct in the bss, just allocate on stack, it's 40/108 bytes which should be safe. Reviewed-by:

When many wavefronts cause VM faults at the same time, it can overwhelm the interrupt handler and cause IH ring overflows before the driver can notify or kill the faulting application. As a workaround I'm introducing limited per-VM fault credit. After that number of VM faults have occurred, further VM faults are filtered out at the prescreen stage of processing. This depends on the PASID in the interrupt packet, so it currently only works for KFD contexts. Signed-off-by:

I've no idea why this is like this, why store 64-bit fields as a string, and then parse the strings, this is just over engineered. Reduce the size of the amdgpu.o by 80k. text data bss dec hex filename 1331332 17982 1008 1350322 149ab2 amdgpu.o 1244668 17982 1008 1263658 13482a amdgpu.o Acked-by:

This is what I'd call slightly overengineered, we waste 40k on storing a value that is write or end, when we could just use the register value to denote end.

This split serves no purpose, and we can make a bunch of functions static now. There are lots of cases of this sort of split in the powerplay code, please start cleaning them up. Ideally the function table is in the same file as all the implementations used in it. Reviewed-by:

This patch provides a guarantee that the first n queues allocated by an application will be on different pipes. Where n is the number of pipes available from the hardware. This helps avoid ring aliasing which can result in work executing in time-sliced mode instead of truly parallel mode. Reviewed-by:
