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. v2 -> v3: - "s390x/tcg: don't exit the cpu loop in s390_cpu_virt_mem_rw()" -- don't break old KVM - Unfortunately not able to come up with a better solution for "s390x: handle exceptions during s390_cpu_virt_mem_rw() correctly (TCG)" so I assume we'll go with this for now. v1 -> v2: - renamed program_interrupt_ra() to s390_program_interrupt() - introduce and use RA_IGNORED for KVM. - switch to cpu_exit_loop_restore() and don't check if ra is set - "s390x: handle exceptions during s390_cpu_virt_mem_rw() correctly (TCG)" -> split out "s390x/tcg: don't exit the cpu loop in s390_cpu_virt_mem_rw()" - "s390x/tcg: use program_interrupt_ra() in SCLP Service Call" -> moved qemu_mutex_lock_iothread(); further up - "s390x/tcg: drop program_interrupt()" -> move restore to tcg_s390_program_interrupt() via cpu_loop_exit_restore() - smaller requested cleanups David Hildenbrand (16): s390x/tcg: introduce and use s390_program_interrupt() 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: don't exit the cpu loop in s390_cpu_virt_mem_rw() s390x/tcg: io instructions don't need potential_page_fault() s390x/tcg: use s390_program_interrupt() in SCLP Service Call s390x/tcg: use s390_program_interrupt() in DIAG s390x/tcg: use s390_program_interrupt() in per_check_exception() s390x/tcg: use s390_program_interrupt() in SACF s390x/tcg: use s390_program_interrupt() 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 | 5 +- 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 | 113 +++++++++++++++++++------------------------ target/s390x/kvm.c | 43 ++++++++-------- target/s390x/mem_helper.c | 35 +++++--------- target/s390x/misc_helper.c | 52 +++++++------------- target/s390x/mmu_helper.c | 23 +++++++-- target/s390x/translate.c | 27 +---------- 19 files changed, 228 insertions(+), 271 deletions(-) -- 2.14.3
