Vineet Gupta 1355ea2e60 ARC: mm: tlb flush optim: elide repeated uTLB invalidate in loop ... The unconditional full TLB flush (on say ASID rollover) iterates over each entry and uses TLBWrite to zero it out. TLBWrite by design also invalidates the uTLBs thus we end up invalidating it as many times as numbe rof entries (512 or 1k) Optimize this by using a weaker TLBWriteNI cmd in loop, which doesn't tinker with uTLBs and an explicit one time IVUTLB, outside the loop to invalidate them all once. And given the optimiztion, the IVUTLB is now needed on MMUv4 too where the uTLBs and JTLBs are otherwise coherent given the TLBInsertEntry / TLBDeleteEntry commands Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2019-10-28 12:12:32 -07:00
