Switch the SPARC target from the old unassigned_access hook to the new do_transaction_failed hook. This will cause the "if transaction failed" code paths added in the previous commits to become active if the access is to an unassigned address. In particular we'll now handle bus errors during page table walks correctly (generating a translation error with the right kind of fault status).

2019-09-17target/sparc: Handle bus errors in mmu_probe()Peter Maydell
Convert the mmu_probe() function to using address_space_ldl() rather than ldl_phys(), so we can explicitly detect memory transaction failures. This makes no practical difference at the moment, because ldl_phys() will return 0 on a transaction failure, and we treat transaction failures and 0 PDEs identically. However the spec says that MMU probe operations are supposed to update the fault status registers, and if we ever implement that we'll want to distinguish the difference. For the moment, just add a TODO comment about the bug.

2019-09-17target/sparc: Correctly handle bus errors in page table walksPeter Maydell
Currently we use the ldl_phys() function to read page table entries. With the unassigned_access hook in place, if these hit an unassigned area of memory then the hook will cause us to wrongly generate an exception with a fault address matching the address of the page table entry. Change to using address_space_ldl() so we can detect and correctly handle bus errors and give them their correct behaviour of causing a translation error with a suitable fault status register. Note that this won't actually take effect until we switch the over to using the do_translation_failed hook.

2019-09-17target/sparc: Check for transaction failures in MXCC stream ASI accessesPeter Maydell
Currently the ld/st_asi helper functions make calls to the ld*_phys() and st*_phys() functions for those ASIs which imply direct accesses to physical addresses. These implicitly rely on the unassigned_access hook to cause them to generate an MMU fault if the access fails. Switch to using the address_space_* functions instead, which return a MemTxResult that we can check. This means that when we switch SPARC over to using the do_transaction_failed hook we'll still get the same MMU faults we did before. This commit converts the ASIs which do MXCC stream source and destination accesses. It's not clear to me whether raising an MMU fault like this is the correct behaviour if we encounter a bus error, but we retain the same behaviour that the old unassigned_access hook would implement.

2019-09-17target/sparc: Factor out the body of sparc_cpu_unassigned_access()Peter Maydell
Currently the SPARC target uses the old-style do_unassigned_access hook. We want to switch it over to do_transaction_failed, but to do this we must first remove all the direct calls in ldst_helper.c to cpu_unassigned_access(). Factor out the body of the hook function's code into a new sparc_raise_mmu_fault() and call it from the hook and from the various places that used to call cpu_unassigned_access(). In passing, this fixes a bug where the code that raised the MMU exception was directly calling GETPC() from a function that was several levels deep in the callstack from the original helper function: the new sparc_raise_mmu_fault() instead takes the return address as an argument. Other than the use of retaddr rather than GETPC() and a comment format fixup, the body of the new function has no changes from that of the old hook function.

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.

In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

2019-05-13Clean up ill-advised or unusual header guardsMarkus Armbruster
Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Done with scripts/clean-header-guards.pl.

2019-05-10tcg: Use CPUClass::tlb_fill in cputlb.cRichard Henderson
We can now use the CPUClass hook instead of a named function. Create a static tlb_fill function to avoid other changes within cputlb.c. This also isolates the asserts within. Remove the named tlb_fill function from all of the targets.

In order to handle TB's that translate to too much code, we need to place the control of the length of the translation in the hands of the code gen master loop.

2019-04-18qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster
CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

2019-04-18target: Clean up how the dump_mmu() printMarkus Armbruster
The various dump_mmu() take an fprintf()-like callback and a FILE * to pass to it, and so do their helper functions. Passing around callback and argument is rather tiresome. Most dump_mmu() are called only by the target's hmp_info_tlb(). These all pass monitor_printf() cast to fprintf_function and the current monitor cast to FILE *. SPARC's dump_mmu() gets also called from target/sparc/ldst_helper.c a few times #ifdef DEBUG_MMU. These calls pass fprintf() and stdout. The type-punning is technically undefined behaviour, but works in practice. Clean up: drop the callback, and call qemu_printf() instead.

2019-04-18target: Simplify how the TARGET_cpu_list() printMarkus Armbruster
The various TARGET_cpu_list() take an fprintf()-like callback and a FILE * to pass to it. Their callers (vl.c's main() via list_cpus(), bsd-user/main.c's main(), linux-user/main.c's main()) all pass fprintf() and stdout. Thus, the flexibility provided by the (rather tiresome) indirection isn't actually used. Drop the callback, and call qemu_printf() instead. Calling printf() would also work, but would make the code unsuitable for monitor context without making it simpler.

We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim.
