TuxSH	114cdc5aa4	thermosphere: use barriers and caches properly. Cache code refactoring - set/way cache ops create losses of coherency, do not broadcast and are only meant to be used on boot, period. Cache ops by VA are the only way to do data cache maintenance. Fix a bug where the L2 cache was evicted by each core. It shouldn't have. - Cleaning dcache to PoU and invalidating icache to PoU, by VA is sufficient for self-modifying code - Since we operate within a single cluster and don't do DMA, we almost always operate within the inner shareability domain (commit untested on real hw)	2020-02-04 19:12:21 +00:00

thermosphere: use barriers and caches *properly*. Cache code refactoring

- set/way cache ops create losses of coherency, do not broadcast and are only meant to be used on boot, period.

Cache ops by VA are **the only way** to do data cache maintenance.

Fix a bug where the L2 cache was evicted by each core. It shouldn't have.

- Cleaning dcache to PoU and invalidating icache to PoU, by VA is sufficient for self-modifying code

- Since we operate within a single cluster and don't do DMA, we almost always operate within the inner shareability domain
