Thomas, Any comment on the series? The changes aren't that comprehensive, so it would be great to merge it in before the 5.10 merge window is opened. -Sergey On Sun, Sep 20, 2020 at 02:00:08PM +0300, Serge Semin wrote: > It has been discovered that on our MIPS P5600-based CPU the IO accessors >

[PATCH 0/2] mips: Introduce some IO-accessors optimizations

2020-09-20 Thread Serge Semin
It has been discovered that on our MIPS P5600-based CPU the IO accessors aren't that rapid as they could be even taking into account a relatively slow AXI2APB bridge embedded into the system interconnect. Turned out we can introduce two types of optimizations. First we can remove the execution
