I have quite some patches on my queue for 2.12. (booting Fedora 26/27 guests, floating interrupts, machine checks, missing instructions ...)
So let's start slowly :) This series gets rid of program_interrupt() and potential_page_fault(). We now always properly restore the cpu state when injecting/delivering a program interrupt. So there is no need to update the state via potential_page_fault() anymore. In addition, handling for program interrupts comming via s390_cpu_virt_mem_rw() was missing something for the TCG case. Also fixed. David Hildenbrand (15): s390x/tcg: introduce and use program_interrupt_ra() s390x/tcg: get rid of runtime_exception() s390x/tcg: rip out dead tpi code s390x/ioinst: pass the retaddr to all IO instructions s390x/pci: pass the retaddr to all PCI instructions s390x/diag: pass the retaddr into handle_diag_308() s390x: handle exceptions during s390_cpu_virt_mem_rw() correctly (TCG) s390x/tcg: io instructions don't need potential_page_fault() s390x/tcg: use program_interrupt_ra() in SCLP Service Call s390x/tcg: use program_interrupt_ra() in DIAG s390x/tcg: use program_interrupt_ra() in per_check_exception() s390x/tcg: use program_interrupt_ra() in SACF s390x/tcg: use program_interrupt_ra() in STSI s390x/tcg: drop program_interrupt() s390x/tcg: drop potential_page_fault() hw/s390x/css.c | 6 --- hw/s390x/s390-pci-inst.c | 90 ++++++++++++++++++---------------- hw/s390x/s390-pci-inst.h | 16 ++++--- include/hw/s390x/css.h | 1 - target/s390x/cc_helper.c | 2 +- target/s390x/cpu.h | 4 +- target/s390x/crypto_helper.c | 7 +-- target/s390x/diag.c | 14 +++--- target/s390x/excp_helper.c | 5 +- target/s390x/fpu_helper.c | 2 +- target/s390x/int_helper.c | 14 +++--- target/s390x/internal.h | 35 +++++++------- target/s390x/interrupt.c | 9 +++- target/s390x/ioinst.c | 112 ++++++++++++++++++++----------------------- target/s390x/kvm.c | 42 ++++++++-------- target/s390x/mem_helper.c | 35 +++++--------- target/s390x/misc_helper.c | 50 +++++++------------ target/s390x/mmu_helper.c | 19 +++++++- target/s390x/translate.c | 27 +---------- 19 files changed, 226 insertions(+), 264 deletions(-) -- 2.14.3
