[LLVMdev] Questions about MachineScheduler
...ll want to plugin your own scheduling strategy, how you interpret the machine model is mostly up to you. What the TargetSchedModel interface does for you is normalize the resources to processor cycles. This is exposed with scaling factors (to avoid division): getResourceFactor, getMicroOpFactor, getLatencyFactor.
So if you have
def HW1 : ProcResource<15>;
def HW2 : ProcResource<3>;
LatencyFactor=15
ResourceFactor(HW1)=1
ResourceFactor(HW2)=5

[LLVMdev] Questions about MachineScheduler
Hi,
I'm working on defining a SchedMachineModel for the Southern Islands
family of GPUs, and I have two questions related to the
MachineScheduler.
1. I have a resource that can process 15 instructions at the same time.
In the TableGen definitions, should I do:
def HWVMEM : ProcResource<15>;
or
let BufferSize = 15 in {
def HWVMEM : ProcResource<1>;
}
2. Southern Islands has
