2021-09-10bsd-user: Update mapping to handle reserved and starting conditionsWarner Losh1-1/+42
Update the reserved base based on what platform we're on, as well as the start of the mmap range. Update routines that find va ranges to interact with the reserved ranges as well as properly align the mapping (this is especially important for targets whose page size does not match the host's). Loop where appropriate when the initial address space offered by mmap does not meet the contraints. This has 18e80c55bb6 from linux-user folded in to the upstream bsd-user code as well.

2021-09-10bsd-user: Add '-0 argv0' option to bsd-user/main.cColin Percival1-0/+6
Previously it was impossible to emulate a program with a file name different from its argv[0]. With this change, you can run qemu -0 fakename realname args which runs the program "realname" with an argv of "fakename args".

2021-05-20Merge remote-tracking branch 'remotes/bsdimp/tags/pull-bsd-user-20210511' ↵Peter Maydell1-201/+89
into staging pull-bsd-user-20210511 is the next round of cleanups to bsd-user in merging the bsd-user fork into qemu. It contains a number of style commits, as well as 3 commits that start to change things: Some unused files are deleted, building the sparc and sparc64 targets are removed, and a structure is renamed. The next set of pull requests will start to execute the following plan: 1. Move existing code around to have a structure similar to the bsd-user fork. 2. Incrementally merge groups of system calls, focused on making x86 work. 3. Once the groups of system calls are all merged, additional platforms will be added back. 4. Concurrently, as changes are requested as part of the merge happen, those changes will be merged into the fork. An experimental merge to tip of master is under test and is what will be updated. 5. Eventually, there will be no diference, and the bsd-user fork will only be a staging area for cutting-edge features prior to upstreaming into qemu mainline. The bsd-user code in qemu has a lot of style issues. This cleans up a number in the files touched. However, the checkpatch.pl detects some incremental issues in the commits. The following are expected, but are corrected in later hashes in this branch. MAINTAINERS does not need to be updated, since all the files added or deleted are covered under existing regexp in MAINTAINERS.

2021-02-16exec: Use cpu_untagged_addr in g2h; split out g2h_untaggedRichard Henderson1-2/+2
Use g2h_untagged in contexts that have no cpu, e.g. the binary loaders that operate before the primary cpu is created. As a colollary, target_mmap and friends must use untagged addresses, since they are used by the loaders. Use g2h_untagged on values returned from target_mmap, as the kernel never applies a tag itself. Use g2h_untagged on all pc values. The only current user of tags, aarch64, removes tags from code addresses upon branch, so "pc" is always untagged. Use g2h with the cpu context on hand wherever possible. Use g2h_untagged in lock_user, which will be updated soon.

2019-06-11qemu-common: Move tcg_enabled() etc. to sysemu/tcg.hMarkus Armbruster1-0/+2
Other accelerators have their own headers: sysemu/hax.h, sysemu/hvf.h, sysemu/kvm.h, sysemu/whpx.h. Only tcg_enabled() & friends sit in qemu-common.h. This necessitates inclusion of qemu-common.h into headers, which is against the rules spelled out in qemu-common.h's file comment. Move tcg_enabled() & friends into their own header sysemu/tcg.h, and adjust #include directives.

2019-04-18qom/cpu: Simplify how CPUClass:cpu_dump_state() printsMarkus Armbruster1-1/+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 *.

2019-04-18target: Simplify how the TARGET_cpu_list() printMarkus Armbruster1-1/+1
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.

2019-04-17log: Make glib logging go through QEMUChristophe Fergeau1-0/+2
This commit adds a error_init() helper which calls g_log_set_default_handler() so that glib logs (g_log, g_warning, ...) are handled similarly to other QEMU logs. This means they will get a timestamp if timestamps are enabled, and they will go through the HMP monitor if one is configured. This commit also adds a call to error_init() to the binaries installed by QEMU. Since error_init() also calls error_set_progname(), this means that *-linux-user, *-bsd-user and qemu-pr-helper messages output with error_report, info_report, ... will slightly change: they will be prefixed by the binary name. glib debug messages are enabled through G_MESSAGES_DEBUG similarly to the glib default log handler. At the moment, this change will mostly impact SPICE logging if your spice version is >= 0.14.1. With older spice versions, this is not going to work as expected, but will not have any ill effect, so this call is not conditional on the SPICE version.

2018-03-19Use cpu_create(type) instead of cpu_init(cpu_model)Igor Mammedov1-1/+3
With all targets defining CPU_RESOLVING_TYPE, refactor cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model) so that callers won't have to know internal resolving cpu type. Place it in exec.c so it could be called from both target independed vl.c and *-user/main.c. That allows us to stop abusing cpu type from MachineClass::default_cpu_type as resolver class in vl.c which were confusing part of cpu_parse_cpu_model(). Also with new parse_cpu_model(), the last users of cpu_init() in null-machine.c and bsd/linux-user targets could be switched to cpu_create() API and cpu_init() API will be removed by follow up patch. With no longer users left remove MachineState::cpu_model field, new code should use MachineState::cpu_type instead and leave cpu_model parsing to generic code in vl.c.
