* target/sparc: Make sparc_cpu_tlb_fill sysemu onlyRichard Henderson2021-11-021-25/+0Star
| | | | | | | | | | | | | The fallback code in cpu_loop_exit_sigsegv is sufficient for sparc linux-user. This makes all of the code in mmu_helper.c sysemu only, so remove the ifdefs and move the file to sparc_softmmu_ss. Remove the code from cpu_loop that handled TT_DFAULT and TT_TFAULT.

* linux-user: Split linux-user internals out of qemu.hPeter Maydell2021-09-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | qemu.h is included in various non-linux-user files (which mostly want the TaskState struct and the functions for doing usermode access to guest addresses like lock_user(), unlock_user(), get_user*(), etc). Split out the parts that are only used in linux-user itself into a new user-internals.h. This leaves qemu.h with basically three things: * the definition of the TaskState struct * the user-access functions and macros * do_brk() all of which are needed by code outside linux-user that includes qemu.h. The addition of all the extra #include lines was done with sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user) (and then undoing the change to fpa11.h).

* qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster2019-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | 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 *.

* linux-user: Don't call gdb_handlesig() before queue_signal()Peter Maydell2018-11-121-12/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | The CPU main-loop routines for linux-user generally call gdb_handlesig() when they're about to queue a SIGTRAP signal. This is wrong, because queue_signal() will cause us to pend a signal, and process_pending_signals() will then call gdb_handlesig() itself. So the effect is that we notify gdb of the SIGTRAP, and then if gdb says "OK, continue with signal X" we will incorrectly notify gdb of the signal X as well. We don't do this double-notify for anything else, only SIGTRAP. Remove this unnecessary and incorrect code from all the targets except for nios2 (whose main loop is doing something different and broken, and will be handled in a separate patch). This bug only manifests if the user responds to the reported SIGTRAP using "signal SIGFOO" rather than "continue"; since the latter is the overwhelmingly common thing to do after a breakpoint most people won't have hit this.
