Hi, This series introduces a new "blocking" console read function for semihosting and plumbs it in to the ARM semihosting code. The main bit of work is Keith's patch (with a few tweaks by me). The other preparatory patches make sure the PC is updated after semihosting succeeds and a little bit of clean-up.
The following patches need review 01 - target arm remove unused EXCP_SEMIHOST leg 02 - target arm only update pc after semihosting compl 04 - tests tcg add a dumb as bricks semihosting consol Alex Bennée (3): target/arm: remove unused EXCP_SEMIHOST leg target/arm: only update pc after semihosting completes tests/tcg: add a dumb-as-bricks semihosting console test Keith Packard (1): semihosting: add qemu_semihosting_console_inc for SYS_READC include/hw/semihosting/console.h | 16 +++++ include/hw/semihosting/semihost.h | 4 ++ hw/semihosting/console.c | 78 +++++++++++++++++++++++ linux-user/aarch64/cpu_loop.c | 1 + linux-user/arm/cpu_loop.c | 1 + linux-user/arm/semihost.c | 23 +++++++ stubs/semihost.c | 4 ++ target/arm/arm-semi.c | 3 +- target/arm/helper.c | 8 +-- target/arm/m_helper.c | 1 + target/arm/translate-a64.c | 2 +- target/arm/translate.c | 6 +- tests/tcg/aarch64/system/semiconsole.c | 36 +++++++++++ vl.c | 3 + tests/tcg/aarch64/Makefile.softmmu-target | 9 ++- 15 files changed, 182 insertions(+), 13 deletions(-) create mode 100644 tests/tcg/aarch64/system/semiconsole.c -- 2.20.1
