Fix nios2-linux-user sigreturn. Enable tests for nios2-linux-user. Remove special handling of SIGSEGV. Check supervisor for eret, bret. Split special registers out of env->regs[]. Clean up interrupt processing. Raise unaligned data and destination exceptions. Set TLBMISC fields correctly on exceptions. Prevent writes to read-only or reserved control fields. Use tcg_constant_tl(). Implement shadow register sets. Implement external interrupt controller interface. Implement vectored interrupt controller. Enable semihosting tests for nios2-softmmu. ---------------------------------------------------------------- Amir Gonnen (5): target/nios2: Check supervisor on eret target/nios2: Add NUM_GP_REGS and NUM_CP_REGS target/nios2: Split out helper for eret instruction hw/intc: Vectored Interrupt Controller (VIC) hw/nios2: Machine with a Vectored Interrupt Controller Richard Henderson (63): linux-user/nios2: Hoist pc advance to the top of EXCP_TRAP linux-user/nios2: Fix clone child return linux-user/nios2: Drop syscall 0 "workaround" linux-user/nios2: Adjust error return linux-user/nios2: Handle special qemu syscall return values linux-user/nios2: Remove do_sigreturn linux-user/nios2: Use QEMU_ESIGRETURN from do_rt_sigreturn tests/tcg/nios2: Re-enable linux-user tests target/nios2: Remove user-only nios2_cpu_do_interrupt target/nios2: Remove nios2_cpu_record_sigsegv target/nios2: Build helper.c for system only linux-user/nios2: Use force_sig_fault for EXCP_DEBUG target/nios2: Stop generating code if gen_check_supervisor fails target/nios2: Split PC out of env->regs[] target/nios2: Fix BRET instruction target/nios2: Do not create TCGv for control registers linux-user/nios2: Only initialize SP and PC in target_cpu_copy_regs target/nios2: Remove cpu_interrupts_enabled target/nios2: Split control registers away from general registers target/nios2: Clean up nios2_cpu_dump_state target/nios2: Use hw/registerfields.h for CR_STATUS fields target/nios2: Use hw/registerfields.h for CR_EXCEPTION fields target/nios2: Use hw/registerfields.h for CR_TLBADDR fields target/nios2: Use hw/registerfields.h for CR_TLBACC fields target/nios2: Rename CR_TLBMISC_WR to CR_TLBMISC_WE target/nios2: Use hw/registerfields.h for CR_TLBMISC fields target/nios2: Move R_FOO and CR_BAR into enumerations target/nios2: Create EXCP_SEMIHOST for semi-hosting target/nios2: Clean up nios2_cpu_do_interrupt target/nios2: Hoist CPU_LOG_INT logging target/nios2: Handle EXCP_UNALIGN and EXCP_UNALIGND target/nios2: Cleanup set of CR_EXCEPTION for do_interrupt target/nios2: Clean up handling of tlbmisc in do_exception target/nios2: Prevent writes to read-only or reserved control fields target/nios2: Implement cpuid target/nios2: Implement CR_STATUS.RSIE target/nios2: Remove CPU_INTERRUPT_NMI target/nios2: Support division error exception target/nios2: Use tcg_constant_tl target/nios2: Split out named structs for [IRJ]_TYPE target/nios2: Split out helpers for gen_i_cmpxx target/nios2: Split out helpers for gen_i_math_logic target/nios2: Split out helpers for gen_r_math_logic target/nios2: Split out helpers for gen_rr_mul_high target/nios2: Split out helpers for gen_rr_shift target/nios2: Introduce dest_gpr target/nios2: Drop CR_STATUS_EH from tb->flags target/nios2: Enable unaligned traps for system mode target/nios2: Create gen_jumpr target/nios2: Hoist set of is_jmp into gen_goto_tb target/nios2: Use gen_goto_tb for DISAS_TOO_MANY target/nios2: Use tcg_gen_lookup_and_goto_ptr target/nios2: Implement Misaligned destination exception target/nios2: Introduce shadow register sets target/nios2: Implement rdprs, wrprs target/nios2: Update helper_eret for shadow registers target/nios2: Implement EIC interrupt processing target/nios2: Advance pc when raising exceptions linux-user/nios2: Handle various SIGILL exceptions hw/nios2: Introduce Nios2MachineState hw/nios2: Move memory regions into Nios2Machine tests/tcg/nios2: Add semihosting multiarch tests tests/tcg/nios2: Add test-shadow-1 configs/targets/nios2-softmmu.mak | 1 + include/hw/intc/nios2_vic.h | 64 +++ linux-user/nios2/target_cpu.h | 1 + target/nios2/cpu.h | 250 +++++++---- target/nios2/helper.h | 5 + tests/tcg/nios2/semicall.h | 28 ++ hw/intc/nios2_vic.c | 313 +++++++++++++ hw/nios2/10m50_devboard.c | 115 +++-- linux-user/elfload.c | 3 +- linux-user/nios2/cpu_loop.c | 96 ++-- linux-user/nios2/signal.c | 25 +- target/nios2/cpu.c | 213 +++++++-- target/nios2/helper.c | 383 +++++++++------- target/nios2/mmu.c | 78 ++-- target/nios2/op_helper.c | 88 ++++ target/nios2/translate.c | 749 ++++++++++++++++++++------------ hw/intc/Kconfig | 3 + hw/intc/meson.build | 1 + hw/nios2/Kconfig | 1 + target/nios2/meson.build | 7 +- tests/tcg/nios2/10m50-ghrd.ld | 66 +++ tests/tcg/nios2/Makefile.softmmu-target | 33 ++ tests/tcg/nios2/Makefile.target | 11 - tests/tcg/nios2/boot.S | 218 ++++++++++ tests/tcg/nios2/intr.S | 31 ++ tests/tcg/nios2/test-shadow-1.S | 40 ++ 26 files changed, 2113 insertions(+), 710 deletions(-) create mode 100644 include/hw/intc/nios2_vic.h create mode 100644 tests/tcg/nios2/semicall.h create mode 100644 hw/intc/nios2_vic.c create mode 100644 tests/tcg/nios2/10m50-ghrd.ld create mode 100644 tests/tcg/nios2/Makefile.softmmu-target delete mode 100644 tests/tcg/nios2/Makefile.target create mode 100644 tests/tcg/nios2/boot.S create mode 100644 tests/tcg/nios2/intr.S create mode 100644 tests/tcg/nios2/test-shadow-1.S
