Subject: [PATCH 0/5] semihosting: Reduce target specific code
Date: Fri,  3 Jan 2025 18:10:32 +0100	[thread overview]
Message-ID: <20250103171037.11265-1-philmd@linaro.org> (raw)

This series makes semihosting config.c and console.c
target agnostic, building them once, removing symbol
collision of the following functions in the single
binary:

 - qemu_semihosting_chardev_init
 - qemu_semihosting_config_options
 - qemu_semihosting_config_opts
 - qemu_semihosting_enable
 - semihosting_arg_fallback
 - semihosting_enabled
 - semihosting_get_argc
 - semihosting_get_target

This function is still problematic, being built for
each target:

 - qemu_semihosting_guestfd_init

Note, it depends on CONFIG_ARM_COMPATIBLE_SEMIHOSTING
which is target specific, so doesn't scale in a
heterogeneous setup like the ZynqMP machine, having
ARM cores with CONFIG_ARM_COMPATIBLE_SEMIHOSTING=y and
MicroBlaze ones with CONFIG_ARM_COMPATIBLE_SEMIHOSTING=n.

I suppose the semihosting API needs rework to consider
the CPUClass? I'll let that investigation for the
maintainer ;)

Regards,

Phil.
