| | | | | | | | Will replace qemu_semihosting_console_{outs,outc}, but we need more plumbing first. Reviewed-by: Luc Michel <lmichel@kalray.eu> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

* semihosting: Pass CPUState to qemu_semihosting_console_incRichard Henderson2022-06-281-1/+1
| | | | | | | | | We don't need CPUArchState, and we do want the CPUState of the thread performing the operation -- use this instead of current_cpu.

* linux-user: Split linux-user internals out of qemu.hPeter Maydell2021-09-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | qemu.h is included in various non-linux-user files (which mostly want the TaskState struct and the functions for doing usermode access to guest addresses like lock_user(), unlock_user(), get_user*(), etc). Split out the parts that are only used in linux-user itself into a new user-internals.h. This leaves qemu.h with basically three things: * the definition of the TaskState struct * the user-access functions and macros * do_brk() all of which are needed by code outside linux-user that includes qemu.h. The addition of all the extra #include lines was done with sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user) (and then undoing the change to fpa11.h).

* semihosting: Move ARM semihosting code to shared directoriesKeith Packard2021-01-181-0/+76
This commit renames two files which provide ARM semihosting support so that they can be shared by other architectures: 1. target/arm/arm-semi.c -> hw/semihosting/common-semi.c 2. linux-user/arm/semihost.c -> linux-user/semihost.c The build system was modified use a new config variable, CONFIG_ARM_COMPATIBLE_SEMIHOSTING, which has been added to the ARM softmmu and linux-user default configs. The contents of the source files has not been changed in this patch.
