build: allow automatic git submodule updates to be disabled Some people building QEMU use VPATH builds where the source directory is on a read-only volume. In such a case 'scripts/git-submodules.sh update' will always fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line flag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbitrary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still run the 'status' command to determine if a submodule update is needed, but when it does this it'll simply stop and print a message instructing the developer what todo. eg $ ./configure --target-list=x86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

Makefile: Fix in-tree builds when Sphinx is available In commit 27a296fce9821e we switched the qemu-ga manpage over to being built from Sphinx. The makefile rules for this were correct for an out-of-tree build, but break for in-tree builds if Sphinx is present and we're trying to build the documentation. Specifically, because Sphinx refuses to build output files into the same directory as its sources, for an in-tree build we tell it to build into a subdirectory docs/built, and set up a makefile variable MANUAL_BUILDDIR indicating where the docs are going. The makefile rule telling Make how to build qemu-ga.8 correctly used this variable, but the lines adding qemu-ga.8 to the list of DOCS to be built and the 'make install' rune did not. The effect was that for an in-tree build we told Make to build 'docs/interop/qemu-ga.8' but did not provide a specific rule for doing so, which caused Make to fall back to the old rules.make rule for building any "%.8" file. Make tried to invoke texi2pod with a bogus command line, resulting in the error: GEN docs/interop/qemu-ga.8 No filename or title make: *** [rules.mak:394: docs/interop/qemu-ga.8] Fix this by using $(MANUAL_BUILDDIR) when constructing the list of DOCS files we want to build and also in the source file name we install for 'make install'. (Among other things, this broke the Shippable CI builds.)

qemu-nbd: Convert invocation documentation to rST The qemu-nbd documentation is currently in qemu-nbd.texi in Texinfo format, which we present to the user as: * a qemu-nbd manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-nbd manpage * part of the interop/ Sphinx manual This follows the same pattern as commit 27a296fce982 did for the qemu-ga manpage. All the content of the old manpage is retained, except that I have dropped the "This is free software; see the source for copying conditions. There is NO warranty..." text that was in the old AUTHOR section; Sphinx's manpage builder doesn't expect that much text in the AUTHOR section, and since none of our other manpages have it it seems easiest to delete it rather than try to figure out where else in the manpage to put it. The only other textual change is that I have had to give the --nocache option its own description ("Equivalent to --cache=none") because Sphinx doesn't have an equivalent of using item/itemx to share a description between two options. Some minor aspects of the formatting have changed, to suit what is easiest for Sphinx to output. (The most notable is that Sphinx option section option syntax doesn't support '--option foo=bar' with bar underlined rather than bold, so we have to switch to '--option foo=BAR' instead.) The contents of qemu-option-trace.texi are now duplicated in docs/interop/qemu-option-trace.rst.inc, until such time as we complete the conversion of the other files which use it; since it has had only 3 changes in 3 years, this shouldn't be too awkward a burden. (We use .rst.inc because if this file fragment has a .rst extension then Sphinx complains about not seeing it in a toctree.)

qemu-block-drivers: Convert to rST The qemu-block-drivers documentation is currently in docs/qemu-block-drivers.texi in Texinfo format, which we present to the user as: * a qemu-block-drivers manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-block-drivers manpage * part of the system/ Sphinx manual This follows the same pattern we've done for qemu-ga and qemu-nbd. We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.

docs/system: Convert qemu-cpu-models.texi to rST This doc was originally written by Daniel P. Berrangé <berrange@redhat.com>, introduced via commit[1]: 2544e9e4aa (docs: add guidance on configuring CPU models for x86, 2018-06-27). In this patch: - 1-1 conversion of Texinfo to rST, besides a couple of minor tweaks that are too trivial to mention. (Thanks to Stephen Finucane on IRC for the suggestion to use rST "definition lists" instead of bullets in some places.) Further modifications will be done via a separate patch. - rST and related infra changes: manual page generation, Makefile fixes, clean up references to qemu-cpu-models.texi, update year in the copyright notice, etc. [1] https://git.qemu.org/?p=qemu.git;a=commit;h=2544e9e4aa As part of the conversion, we use a more generic 'author' attribution for the manpage than we previously had, as agreed with the original author Dan Berrange.

In that case you'd do $ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*' And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset is used for the trace session The 'qemu-trace-stap' script takes a verbose arg so you can understand what it is running $ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*' Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64' Compiling script 'probe qemu.system.x86_64.log.qio* {}' Running script, <Ctrl>-c to quit ...trace output... It can enable multiple probes at once $ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*' By default it monitors all existing running processes and all future launched proceses. This can be restricted to a specific PID using the --pid arg $ qemu-trace-stap run --pid 2532 qemu-system-x86_64 'qio*' Finally if you can't remember what probes are valid it can tell you $ qemu-trace-stap list qemu-system-x86_64 ahci_check_irq ahci_cmd_done ahci_dma_prepare_buf ahci_dma_prepare_buf_fail ahci_dma_rw_buf ahci_irq_lower ...snip... Or list just those matching a prefix pattern $ qemu-trace-stap list -v qemu-system-x86_64 'qio*' Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64' Listing probes with name 'qemu.system.x86_64.log.qio*' qio_channel_command_abort qio_channel_command_new_pid qio_channel_command_new_spawn qio_channel_command_wait qio_channel_file_new_fd ...snip...

rules.mak: quiet-command: Split command name and args to print The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".

qemu-block-drivers: Convert to rST The qemu-block-drivers documentation is currently in docs/qemu-block-drivers.texi in Texinfo format, which we present to the user as: * a qemu-block-drivers manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-block-drivers manpage * part of the system/ Sphinx manual This follows the same pattern we've done for qemu-ga and qemu-nbd. We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.

docs/system: Convert qemu-cpu-models.texi to rST This doc was originally written by Daniel P. Berrangé <berrange@redhat.com>, introduced via commit[1]: 2544e9e4aa (docs: add guidance on configuring CPU models for x86, 2018-06-27). In this patch: - 1-1 conversion of Texinfo to rST, besides a couple of minor tweaks that are too trivial to mention. (Thanks to Stephen Finucane on IRC for the suggestion to use rST "definition lists" instead of bullets in some places.) Further modifications will be done via a separate patch. - rST and related infra changes: manual page generation, Makefile fixes, clean up references to qemu-cpu-models.texi, update year in the copyright notice, etc. [1] https://git.qemu.org/?p=qemu.git;a=commit;h=2544e9e4aa As part of the conversion, we use a more generic 'author' attribution for the manpage than we previously had, as agreed with the original author Dan Berrange.

Makefile: Fix in-tree builds when Sphinx is available In commit 27a296fce9821e we switched the qemu-ga manpage over to being built from Sphinx. The makefile rules for this were correct for an out-of-tree build, but break for in-tree builds if Sphinx is present and we're trying to build the documentation. Specifically, because Sphinx refuses to build output files into the same directory as its sources, for an in-tree build we tell it to build into a subdirectory docs/built, and set up a makefile variable MANUAL_BUILDDIR indicating where the docs are going. The makefile rule telling Make how to build qemu-ga.8 correctly used this variable, but the lines adding qemu-ga.8 to the list of DOCS to be built and the 'make install' rune did not. The effect was that for an in-tree build we told Make to build 'docs/interop/qemu-ga.8' but did not provide a specific rule for doing so, which caused Make to fall back to the old rules.make rule for building any "%.8" file. Make tried to invoke texi2pod with a bogus command line, resulting in the error: GEN docs/interop/qemu-ga.8 No filename or title make: *** [rules.mak:394: docs/interop/qemu-ga.8] Fix this by using $(MANUAL_BUILDDIR) when constructing the list of DOCS files we want to build and also in the source file name we install for 'make install'. (Among other things, this broke the Shippable CI builds.)

trace: add ability to do simple printf logging via systemtap The dtrace systemtap trace backend for QEMU is very powerful but it is also somewhat unfriendly to users who aren't familiar with systemtap, or who don't need its power right now. stap -e "....some strange script...." The 'log' backend for QEMU by comparison is very crude but incredibly easy to use: $ qemu -d trace:qio* ...some args... 23266@1547735759.137292:qio_channel_socket_new Socket new ioc=0x563a8a39d400 23266@1547735759.137305:qio_task_new Task new task=0x563a891d0570 source=0x563a8a39d400 func=0x563a86f1e6c0 opaque=0x563a89078000 23266@1547735759.137326:qio_task_thread_start Task thread start task=0x563a891d0570 worker=0x563a86f1ce50 opaque=0x563a891d9d90 23273@1547735759.137491:qio_task_thread_run Task thread run task=0x563a891d0570 23273@1547735759.137503:qio_channel_socket_connect_sync Socket connect sync ioc=0x563a8a39d400 addr=0x563a891d9d90 23273@1547735759.138108:qio_channel_socket_connect_fail Socket connect fail ioc=0x563a8a39d400 This commit introduces a way to do simple printf style logging of probe points using systemtap. In particular it creates another set of tapsets, one per emulator: /usr/share/systemtap/tapset/qemu-*-log.stp These pre-define probe functions which simply call printf() on their arguments. The printf() format string is taken from the normal trace-events files, with a little munging to the format specifiers to cope with systemtap's more restrictive syntax. With this you can now do $ stap -e 'probe qemu.system.x86_64.log.qio*{}' 22806@1547735341399856820 qio_channel_socket_new Socket new ioc=0x56135d1d7c00 22806@1547735341399862570 qio_task_new Task new task=0x56135cd66eb0 source=0x56135d1d7c00 func=0x56135af746c0 opaque=0x56135bf06400 22806@1547735341399865943 qio_task_thread_start Task thread start task=0x56135cd66eb0 worker=0x56135af72e50 opaque=0x56135c071d70 22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0 We go one step further though and introduce a 'qemu-trace-stap' tool to make this even easier $ qemu-trace-stap run qemu-system-x86_64 'qio*' 22806@1547735341399856820 qio_channel_socket_new Socket new ioc=0x56135d1d7c00 22806@1547735341399862570 qio_task_new Task new task=0x56135cd66eb0 source=0x56135d1d7c00 func=0x56135af746c0 opaque=0x56135bf06400 22806@1547735341399865943 qio_task_thread_start Task thread start task=0x56135cd66eb0 worker=0x56135af72e50 opaque=0x56135c071d70 22806@1547735341399976816 qio_task_thread_run Task thread run task=0x56135cd66eb0 This tool is clever in that it will automatically change the SYSTEMTAP_TAPSET env variable to point to the directory containing the right set of probes for the QEMU binary path you give it. This is useful if you have QEMU installed in /usr but are trying to test and trace a binary in /home/berrange/usr/qemu-git. In that case you'd do $ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*' And it'll make sure /home/berrange/usr/qemu-git/share/systemtap/tapset is used for the trace session The 'qemu-trace-stap' script takes a verbose arg so you can understand what it is running $ qemu-trace-stap run /home/berrange/usr/qemu-git/bin/qemu-system-x86_64 'qio*' Using tapset dir '/home/berrange/usr/qemu-git/share/systemtap/tapset' for binary '/home/berrange/usr/qemu-git/bin/qemu-system-x86_64' Compiling script 'probe qemu.system.x86_64.log.qio* {}' Running script, <Ctrl>-c to quit ...trace output... It can enable multiple probes at once $ qemu-trace-stap run qemu-system-x86_64 'qio*' 'qcrypto*' 'buffer*' By default it monitors all existing running processes and all future launched proceses. This can be restricted to a specific PID using the --pid arg $ qemu-trace-stap run --pid 2532 qemu-system-x86_64 'qio*' Finally if you can't remember what probes are valid it can tell you $ qemu-trace-stap list qemu-system-x86_64 ahci_check_irq ahci_cmd_done ahci_dma_prepare_buf ahci_dma_prepare_buf_fail ahci_dma_rw_buf ahci_irq_lower ...snip...

qemu-nbd: Convert invocation documentation to rST The qemu-nbd documentation is currently in qemu-nbd.texi in Texinfo format, which we present to the user as: * a qemu-nbd manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-nbd manpage * part of the interop/ Sphinx manual This follows the same pattern as commit 27a296fce982 did for the qemu-ga manpage. All the content of the old manpage is retained, except that I have dropped the "This is free software; see the source for copying conditions. There is NO warranty..." text that was in the old AUTHOR section; Sphinx's manpage builder doesn't expect that much text in the AUTHOR section, and since none of our other manpages have it it seems easiest to delete it rather than try to figure out where else in the manpage to put it. The only other textual change is that I have had to give the --nocache option its own description ("Equivalent to --cache=none") because Sphinx doesn't have an equivalent of using item/itemx to share a description between two options. Some minor aspects of the formatting have changed, to suit what is easiest for Sphinx to output. (The most notable is that Sphinx option section option syntax doesn't support '--option foo=bar' with bar underlined rather than bold, so we have to switch to '--option foo=BAR' instead.) The contents of qemu-option-trace.texi are now duplicated in docs/interop/qemu-option-trace.rst.inc, until such time as we complete the conversion of the other files which use it; since it has had only 3 changes in 3 years, this shouldn't be too awkward a burden. (We use .rst.inc because if this file fragment has a .rst extension then Sphinx complains about not seeing it in a toctree.)

We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.
