If we run qemu with an Hexagon binary compiled to an arch version that is higher than the threshold modeled by qemu, we will get the following error: qemu-hexagon: unable to find CPU model 'unknown' This can be confusing ("Was qemu unable to read the arch version from this binary? Or did it read but does not know such version?"). And running `qemu-hexagon -cpu help` doesn't help either, as it just errors out with no output. This patchset tries to improve this process. https://lore.kernel.org/qemu-devel/cover.1673616964.git.quic_mathbern@quicinc.com/ Matheus Tavares Bernardino (2): Hexagon: list available CPUs with `-cpu help` Hexagon: append eflags to unknown cpu model string linux-user/hexagon/target_elf.h | 7 ++++++- target/hexagon/cpu.h | 3 +++ target/hexagon/cpu.c | 20 ++++++++++++++++++++ 3 files changed, 29 insertions(+), 1 deletion(-)
