From ba02946a903015840ef672ccc9dc8620a7e83de6 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 11 Oct 2007 17:07:34 -0500 Subject: [POWERPC] Fix handling of stfiwx math emulation Its legal for the stfiwx instruction to have RA = 0 as part of its effective address calculation. This is illegal for all other XE form instructions. Add code to compute the proper effective address for stfiwx if RA = 0 rather than treating it as illegal.

It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too.

Since we might have misconfigured firmware or cpus that have a linesize that isnt 128 bytes, I still print it out for those cases. If people would prefer to remove it completely, lets do it.

As a result, we have to always use slbia when switching context. We don't have to worry about changing the slbie's during fault processing, since they should never be replacing one VSID with another using the same ESID. I.e. there's no risk for inserting duplicate entries due to a failed slbie of the old entry. So as long as we clear it out on context switch we should be fine.
