[PATCH v6 0/4] target/arm: Add support for FEAT_TLBIOS and FEAT_TLBIRANGE

Posted by Rebecca Cran 3 years ago

ARMv8.4 adds the mandatory FEAT_TLBIOS and FEAT_TLBIRANGE. 
They provides TLBI maintenance instructions that extend to the Outer
Shareable domain and that apply to a range of input addresses.

Changes from v5 to v6:

Fixed wrapping of functions in exec-all.h to avoid exceeding the
80 character limit. checkpatch.pl now passes.

Rebecca Cran (4):
  accel/tcg: Add TLB invalidation support for ranges of addresses
  target/arm: Add support for FEAT_TLBIRANGE
  target/arm: Add support for FEAT_TLBIOS
  target/arm: set ID_AA64ISAR0.TLB to 2 for max AARCH64 CPU type
