artful: rfi-flush: Switch to new linear fallback flush |
rfi-flush: Switch to new linear fallback flush |
|
2018-05-08 10:09:14 |
Juerg Haefliger |
description |
Change flush from congruence-first with dependencies to linear with
no dependencies, which increases flush performance by 8x on P8, and
3x on P9 (as measured with null syscall loop, which will have the
flush area in the L2).
The flush also becomes simpler and more adaptable to different cache
geometries. |
[Impact]
Change flush from congruence-first with dependencies to linear with
no dependencies, which increases flush performance by 8x on P8, and
3x on P9 (as measured with null syscall loop, which will have the
flush area in the L2).
The flush also becomes simpler and more adaptable to different cache
geometries.
[Test Case]
TBD.
[Regression Potential]
The risk is deemed low since the changes are confined to POWER only and the provided test kernels have been tested by IBM. |

[Impact]
Change flush method from "congruence-first with dependencies" to "linear with no dependencies", which increases flush performance by 8x on P8, and
3x on P9. Measured with null syscall loop, which will have the flush area in the L2 cache.
The flush also becomes simpler and more adaptable to different cache
geometries.
[Test Case]
TBD.
