semihosting/uaccess: Avoid including 'cpu.h'

2024-04-26T13:31:37Z

"semihosting/uaccess.h" only requires the following headers: - "exec/cpu-defs.h" for target_ulong, - "exec/cpu-common.h" for cpu_memory_rw_debug() - "exec/tswap.h" for tswap32() and tswap64(). Include them instead of the huge "cpu.h". Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Richard Henderson Message-Id: <42c6471e-8383-45e0-85ee-e20ca32ecbad@linaro.org>

semihosting: Rename softmmu_FOO_user() -> uaccess_FOO_user()

2023-10-07T17:02:59Z

Add a check in 'softmmu-uaccess.h' that the header is only include in system emulation, and rename it as 'uaccess.h'. Rename the API methods: - softmmu_[un]lock_user*() -> uaccess_[un]lock_user*() - softmmu_strlen_user() -> uaccess_strlen_user(). Update a pair of comments.

semihosting: Allow optional use of semihosting from userspace

2022-09-13T16:18:21Z

Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.
