Subject: [PATCH v7 0/4] Add support for FEAT_TLBIOS and FEAT_TLBIRANGE
Date: Wed, 14 Apr 2021 14:32:27 -0600	[thread overview]
Message-ID: <20210414203231.824-1-rebecca@nuviainc.com> (raw)

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 v6 to v7:

o Fixed the tlbi_aa64_rvae1_write the tlbi_aa64_rvae1is_write functions
  to pass the correct value into functions which use an ARMMMUIdx.

o Fixed comments in helper.c which referred to non-existent instructions.

Testing:

o Booted Linux 5.11 - verified the previous assert failure in qemu is
  resolved.
o Ran checkpatch.pl.

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
