* hppa/tcg: Call probe_write() also for CONFIG_USER_ONLYDavid Hildenbrand2019-09-031-2/+0Star
| | | | | | | | | We now have a variant for CONFIG_USER_ONLY as well.

* sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster2019-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

* target/hppa: Use env_cpu, env_archcpuRichard Henderson2019-06-101-5/+3Star
| | | | | | | | | | | Cleanup in the boilerplate that each target must define. Replace hppa_env_get_cpu with env_archcpu. The combination CPU(hppa_env_get_cpu) should have used ENV_GET_CPU to begin; use env_cpu now.

* cpu: Replace ENV_GET_CPU with env_cpuRichard Henderson2019-06-101-1/+1
| | | | | | | | | Now that we have both ArchCPU and CPUArchState, we can define this generically instead of via macro in each target's cpu.h.

| | | | | | | | | When QEMU is compiled with -O0, these functions are inlined which will cause a wrong restart address generated for the TB.

* target/hppa: fix PSW Q bit behaviour to match hardwareSven Schnelle2019-02-061-5/+9
| | | | | | | | | | | | | | PA-RISC specification says: "Setting the PSW Q-bit, PSW{28}, to 1 with this instruction, if it was not already 1, is an undefined operation." However, at least HP-UX 10.20 sets the Q bit from 0 to 1 with the SSM instruction. Tested this both on HP9000/712 and HP9000/785/C3750, both machines set the Q bit from 0 to 1 without exception. This makes HP-UX 10.20 progress a little bit further.

* target/*/cpu.h: remove softfloat.hAlex Bennée2018-02-211-1/+1
| | | | | | | | | | | | | | | | | As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.

* accel/tcg: add size paremeter in tlb_fill()Laurent Vivier2018-01-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).

This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.
