The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.

* arm/{bcm2835,fsl-imx25,fsl-imx6}: Fix realize error API violationsMarkus Armbruster2020-07-021-7/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. bcm2835_peripherals_realize(), fsl_imx25_realize() and fsl_imx6_realize() are wrong that way: they pass &err to object_property_set_uint() and object_property_set_bool() without checking it, and then to sysbus_realize(). Harmless, because the former can't actually fail here. Fix by passing &error_abort instead.

* fsl_imx*: Migrate ROM contentsPeter Maydell2017-07-241-2/+2
| | | | | | | | | | | | | | | | | | | | | The fsl-imx* boards accidentally forgot to register the ROM memory regions for migration. This used to require a manual step of calling vmstate_register_ram(), but following commits 1cfe48c1ce21..b08199c6fbea194 we can use memory_region_init_rom() to have it do the migration for us. This is a migration break, but the migration code currently does not handle the case of having two RAM regions which were not registered for migration, and so prior to this commit a migration load would always fail with: "qemu-system-arm: Length mismatch: 0x4000 in != 0x18000: Invalid argument" NB: migration appears at this point to be broken for this board anyway -- it succeeds but the destination hangs; probably some device in the system does not yet support migration.

| | | | | | | | | | | | | | | | | | | | | | | | | | In various Freescale SOCs, the GPT timers can be configured to select its input clock. Depending on the SOC the set of available input clocks may vary. The actual single GPT definition was no good enough and because of it booting the sabrelite board with a i.MX6DL device tree would fail because of an incorrect input clock definition for the i.MX6DL SOC. This patch fixes the i.MX6DL boot failure by adding the ability to define a different set of input clocks depending on the considered SOC. A different class has been defined for i.MX25, i.MX31 and i.MX6 each with its specific set of input clocks. The patch has been tested by booting KZM, i.MX25 PDK, i.MX6Q sabrelite and i.MX6DL sabrelite.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

This breaks at least device-list-properties, because qmp_device_list_properties() needs to create a device to find its properties. Broken in commit f4eb32b "qmp: show QOM properties in device-list-properties", v2.1. Example reproducer: $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } } qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed. Aborted (core dumped) [Exit 134 (SIGABRT)] Unfortunately, I can't fix the problems in these devices right now. Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet to mark them: * Hang during cleanup (didn't debug, so I can't say why): "realview_pci", "versatile_pci". * Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic", "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such CPUs * Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu", "host-powerpc64-cpu", "host-embedded-powerpc-cpu", "host-powerpc-cpu" (the powerpc ones can't currently reach the assertion, because the CPUs are only registered when KVM is enabled, but the assertion is arguably in the wrong place all the same) Make qmp_device_list_properties() fail cleanly when the device is so marked. This improves device-list-properties from "crashes, hangs or leaves dangling pointers behind" to "fails". Not a complete fix, just a better-than-nothing work-around. In the above reproducer, device-list-properties now fails with "Can't list properties of device 'pxa2xx-pcmcia'". This also protects -device FOO,help, which uses the same machinery since commit ef52358 "qdev-monitor: include QOM properties in -device FOO, help output", v2.2.
