* qapi: Extract PCI commands to 'pci.json'Philippe Mathieu-Daudé2020-09-291-1/+1
| | | | | | | | | | | | | | | | | | Only qemu-system-FOO and qemu-storage-daemon provide QMP monitors, therefore such declarations and definitions are irrelevant for user-mode emulation. Extracting the PCI commands to their own schema reduces the size of the qapi-misc* headers generated, and pulls less QAPI-generated code into user-mode.

* pci-stub: add more MSI functionsPaolo Bonzini2019-12-171-0/+27
| | | | | | | | | On x86, KVM needs some function from the PCI subsystem in order to set up interrupt routes. Provide some stubs to support x86 machines that lack PCI. Reviewed-by: Sergio Lopez <slp@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* hw/pci/pci-stub: Add msi_enabled() and msi_notify() to the pci stubsThomas Huth2019-05-131-0/+11
| | | | | | | | | | | | | | Some machines have an AHCI adapter, but no PCI. To be able to compile hw/ide/ahci.c without CONFIG_PCI, we still need the two functions msi_enabled() and msi_notify() for linking. This is required for the new Kconfig-like build system, if a user wants to compile a QEMU binary with just one machine that has AHCI, but no PCI, like the ARM "cubieboard" for example.

* qapi: Empty out qapi-schema.jsonMarkus Armbruster2018-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day. Adding a type to qapi/migration.json now recompiles some 120 instead of 2300 out of 5100 objects.

* Include qapi/error.h exactly where neededMarkus Armbruster2018-02-091-0/+1
| | | | | | | | | | | | | | This cleanup makes the number of objects depending on qapi/error.h drop from 1910 (out of 4743) to 1612 in my "build everything" tree. While there, separate #include from file comment with a blank line, and drop a useless comment on why qemu/osdep.h is included first.

* kvm: remove hard dependency on pciCornelia Huck2017-08-301-0/+14
| | | | | | | | | | | | | | | The msi routing code in kvm calls some pci functions: provide some stubs to enable builds without pci. Also, to make this more obvious, guard them via a pci_available boolean (which also can be reused in other places).

* hw/pci: define msi_nonbroken in pci-stubPhilippe Mathieu-Daudé2017-07-111-0/+3
| | | | | | | | | | | | | The kludged field 'msi_nonbroken' is declared in "hw/pci/msi.h" and defined in hw/pci/msi.c. When using an ARM config with CONFIG_PCI disabled, hw/pci/msi.c is not included. Without being PCI-related, the files hw/intc/arm_gicv[23*].c do access this field (to enable the kludge if PCI is enabled). The final link fails since hw/pci/msi.c is not included. Defining this field in pci-stub is safe enough for configs without CONFIG_PCI. Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

* qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster2015-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

* monitor: Use trad. command interface for HMP pcie_aer_inject_errorMarkus Armbruster2015-06-021-13/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | All QMP commands use the "new" handler interface (mhandler.cmd_new). Most HMP commands still use the traditional interface (mhandler.cmd), but a few use the "new" one. Complicates handle_user_command() for no gain, so I'm converting these to the traditional interface. pcie_aer_inject_error's implementation is split into the hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The former is a peculiar crossbreed between HMP and QMP handler. On success, it works like a QMP handler: store QDict through ret_data parameter, return 0. Printing the QDict is left to pcie_aer_inject_error_print(). On failure, it works more like an HMP handler: print error to monitor, return negative number. To convert to the traditional interface, turn pcie_aer_inject_error_print() into a command handler wrapping around hmp_pcie_aer_inject_error(). By convention, this command handler should be called hmp_pcie_aer_inject_error(), so rename the existing hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

* hmp: Name HMP command handler functions hmp_COMMAND()Markus Armbruster2015-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Some are called do_COMMAND() (old ones, usually), some hmp_COMMAND(), and sometimes COMMAND pointlessly differs in spelling. Normalize to hmp_COMMAND(), where COMMAND is exactly the command name with '-' replaced by '_'. Exceptions: * do_device_add() and client_migrate_info() *not* renamed to hmp_device_add(), hmp_client_migrate_info(), because they're also QMP handlers. They still need to be converted to QAPI. * do_memory_dump(), do_physical_memory_dump(), do_ioport_read(), do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(), hmp_i(), hmp_o(), because those names are too cryptic for my taste. * do_info_help() renamed to hmp_info_help() instead of hmp_info(), because it only covers help.
