Re: [PATCH 0/3] hwspinlock: sun6i: Allwinner D1 and T113 support

Hi Wilken,

I observed something like a 4.5x slowdown - around 12 us per take/free on
the C906: the loop with the lock runs at ~14.7 us/iteration, the same loop
without it at ~3.3 us.

So yes, the effect is material.

Greetings,
Indrek
