[PATCH v2 0/3] ppc: Check for bad Radix configs

Posted by Leandro Lupori 3 years, 7 months ago

Changes from v1:
- Use proper format defines in logs
- Optimized ppc_radix64_is_valid_level() and added a comment with
  instructions on how to proceed when adding new Radix CPUs with
  different configurations
- Moved calls to ppc_radix64_is_valid_level() outside of
  ppc_radix64_next_level(). This also avoids calling it twice for
  level 0, through ppc_radix64_walk_tree().
- Removed debug ifdefs from PDE/PTE alignment checks

Leandro Lupori (3):
  ppc: Check partition and process table alignment
  target/ppc: Improve Radix xlate level validation
  target/ppc: Check page dir/table base alignment
