Don't forget to convert the ELF files to binary via: objcopy -O binary s390x/test.elf test.bin For this to work we added: * Initial PSW in lowcore * Switch to 64 bit and z/Arch * SCLP linemode console This is an early version, linemode currently splits lines a bit too often and I still need to polish comments and cleanup code. v2: * Moved cleanup to the front and broadened patch * Split up SCLP patch into interrupt and linemode * Removed unneeded instructions * Improved comments and commit messages Janosch Frank (6): s390x: Cleanup sclp-ascii.c and add sigp order definitions s390x: Make tests bootable from disk s390x: Switch to z/Arch if needed s390x: Add BSS clearing for non ELF boot s390x: Use interrupts in SCLP s390x: Add linemode console lib/s390x/asm/arch_def.h | 19 ++++ lib/s390x/asm/interrupt.h | 2 + lib/s390x/interrupt.c | 12 ++- lib/s390x/io.c | 5 +- lib/s390x/sclp-ascii.c | 68 --------------- lib/s390x/sclp-console.c | 214 ++++++++++++++++++++++++++++++++++++++++++++++ lib/s390x/sclp.c | 42 +++++++++ lib/s390x/sclp.h | 73 +++++++++++++++- s390x/Makefile | 2 +- s390x/cstart64.S | 40 ++++++++- s390x/flat.lds | 10 ++- 11 files changed, 409 insertions(+), 78 deletions(-) delete mode 100644 lib/s390x/sclp-ascii.c create mode 100644 lib/s390x/sclp-console.c
