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 v2 to v3:
o Change the functions in cputlb.c to do a full flush. This should
only be a short-term implementation.
Testing:
o Ran scripts/checkpatch.pl: functions in exec-all.h fail,
but I think that's acceptable?
o Built all targets
o Ran test code that executed the new instructions
o Ran "make test"
Rebecca Cran (3):
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
