As the POWER series of processors (at least up +to POWER9) require changes in the hypervisor to work on a new processor +generation, this gives us an opportunity with POWER9 to clean up several +parts of the OPAL API. + +Eventually, when the kernel drops support for POWER8 and before, we can then +remove the associated kernel code too. + + +TODO +---- +Things we still have to do for POWER9: +- remove opal-v2 from compatible string. +- PCI to use async API rather than returning delays +- deprecate/remove v1 APIs where there's a V2 |
