The context allocation scheme we use depends upon there being a 1<-->1 mapping from cpu to physical TLB for correctness. Chips like Niagara break this assumption. So what we do is notify all cpus with a cross call when the context version number changes, and if necessary this makes them allocate a valid context for the address space they are running at the time. Stress tested with make -j1024, make -j2048, and make -j4096 kernel builds on a 32-strand, 8 core, T2000 with 16GB of ram. Signed-off-by: David S. Miller <davem@davemloft.net> |
