2018-03-19Use cpu_create(type) instead of cpu_init(cpu_model)Igor Mammedov
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.

2018-03-12Polish the version strings containing the package versionThomas Huth
Since commit 67a1de0d195a there is no space anymore between the version number and the parentheses when running configure with --with-pkgversion=foo : $ qemu-system-s390x --version QEMU emulator version 2.11.50(foo) But the space is included when building without that option when building from a git checkout: $ qemu-system-s390x --version QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty) The same confusion exists with the "query-version" QMP command. Let's fix this by introducing a proper QEMU_FULL_VERSION definition that includes the space and parentheses, while the QEMU_PKGVERSION should just cleanly contain the package version string itself. Note that this also changes the behavior of the "query-version" QMP command (the space and parentheses are not included there anymore), but that's supposed to be OK since the strings there are not meant to be parsed by other tools.

2017-10-24tcg: introduce regions to split code_gen_bufferEmilio G. Cota
This is groundwork for supporting multiple TCG contexts. The naive solution here is to split code_gen_buffer statically among the TCG threads; this however results in poor utilization if translation needs are different across TCG threads. What we do here is to add an extra layer of indirection, assigning regions that act just like pages do in virtual memory allocation. (BTW if you are wondering about the chosen naming, I did not want to use blocks or pages because those are already heavily used in QEMU). We use a global lock to serialize allocations as well as statistics reporting (we now export the size of the used code_gen_buffer with tcg_code_size()). Note that for the allocator we could just use a counter and atomic_inc; however, that would complicate the gathering of tcg_code_size()-like stats. So given that the region operations are not a fast path, a lock seems the most reasonable choice. The effectiveness of this approach is clear after seeing some numbers. I used the bootup+shutdown of debian-arm with '-tb-size 80' as a benchmark. Note that I'm evaluating this after enabling per-thread TCG (which is done by a subsequent commit). * -smp 1, 1 region (entire buffer): qemu: flush code_size=83885014 nb_tbs=154739 avg_tb_size=357 qemu: flush code_size=83884902 nb_tbs=153136 avg_tb_size=363 qemu: flush code_size=83885014 nb_tbs=152777 avg_tb_size=364 qemu: flush code_size=83884950 nb_tbs=150057 avg_tb_size=373 qemu: flush code_size=83884998 nb_tbs=150234 avg_tb_size=373 qemu: flush code_size=83885014 nb_tbs=154009 avg_tb_size=360 qemu: flush code_size=83885014 nb_tbs=151007 avg_tb_size=370 qemu: flush code_size=83885014 nb_tbs=151816 avg_tb_size=367 That is, 8 flushes. * -smp 8, 32 regions (80/32 MB per region) [i.e. this patch]: qemu: flush code_size=76328008 nb_tbs=141040 avg_tb_size=356 qemu: flush code_size=75366534 nb_tbs=138000 avg_tb_size=361 qemu: flush code_size=76864546 nb_tbs=140653 avg_tb_size=361 qemu: flush code_size=76309084 nb_tbs=135945 avg_tb_size=375 qemu: flush code_size=74581856 nb_tbs=132909 avg_tb_size=375 qemu: flush code_size=73927256 nb_tbs=135616 avg_tb_size=360 qemu: flush code_size=78629426 nb_tbs=142896 avg_tb_size=365 qemu: flush code_size=76667052 nb_tbs=138508 avg_tb_size=368 Again, 8 flushes.

2017-08-08maint: Include bug-reporting info in --help outputEric Blake
These days, many programs are including a bug-reporting address, or better yet, a link to the project web site, at the tail of their --help output. However, we were not very consistent at doing so: only qemu-nbd and qemu-qa mentioned anything, with the latter pointing to an individual person instead of the project. Add a new #define that sets up a uniform string, mentioning both bug reporting instructions and overall project details, and which a downstream vendor could tweak if they want bugs to go to a downstream database. Then use it in all of our binaries which have --help output. The canned text intentionally references http:// instead of https:// because our https website currently causes certificate errors in some browsers. That can be tweaked later once we have resolved the web site issued. Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Daniel P.

2017-07-14qom/cpu: remove host_tid fieldAlex Bennée
This was only used by the gdbstub and even then was only being set for subsequent threads. Rather the continue duplicating the number just make the gdbstub get the information from TaskState structure. Now the tid is correctly reported for all threads the bug I was seeing with "vCont;C04:0;c" packets is fixed as the correct tid is reported to gdb. I moved cpu_gdb_index into the gdbstub to facilitate easy access to the TaskState which is used elsewhere in gdbstub. To prevent BSD failing to build I've included ts_tid into its TaskStruct but not populated it - which was the same state as the old cpu->host_tid. I'll leave it up to the BSD maintainers to actually populate this properly if they want a working gdbstub with user-threads.

2016-06-20log: Fix qemu_set_log_filename() error handlingMarkus Armbruster
When qemu_set_log_filename() detects an invalid file name, it reports an error, closes the log file (if any), and starts logging to stderr (unless daemonized or nothing is being logged). This is wrong. Asking for an invalid log file on the command line should be fatal. Asking for one in the monitor should fail without messing up an existing logfile. Fix by converting qemu_set_log_filename() to Error. Pass it &error_fatal, except for hmp_logfile report errors. This also permits testing without a subprocess, so do that.
