Hi,
This is a bundle of fixes based on discoveries that were made in the
last week or so:
- what we call "named features" are actually real extensions, which are
considered to be ratified by the profile spec that defines them. This
means that we need to add riscv,isa strings for them. More info can be
found on the commit msg of patch 2;
- the design behind 'svade' and 'svadu' is wrong. 'svade' does not mean
'we do not have svadu'. In fact they can coexist. Patch 5 gives more
details about it.
After this series, 'svade' is promoted to a regular extension and all
the named features QEMU implements are now being displayed in riscv,isa.
Andrew Jones (3):
target/riscv: Reset henvcfg to zero
target/riscv: Gate hardware A/D PTE bit updating
target/riscv: Promote svade to a normal extension
Daniel Henrique Barboza (3):
target/riscv/tcg: set 'mmu' with 'satp' in cpu_set_profile()
target/riscv: add riscv,isa to named features
target/riscv: add remaining named features
