2018-04-26hw/arm/fsl-imx*: Don't create "null" chardevs for serial devicesPeter Maydell
Following commit 12051d82f004024, UART devices should handle being passed a NULL pointer chardev, so we don't need to create "null" backends in board code. Remove the code that does this and updates serial_hds[]. (fsl-imx7.c was already written this way.)

2017-11-07hw/arm: Mark the "fsl,imx31" device with user_creatable = falseThomas Huth
QEMU currently crashes when the user tries to instantiate the fsl,imx31 device manually: $ aarch64-softmmu/qemu-system-aarch64 -M kzm -device fsl,,imx31 ** ERROR:/home/thuth/devel/qemu/tcg/tcg.c:538:tcg_register_thread: assertion failed: (n < max_cpus) Aborted (core dumped) The kzm board (which is the one that uses this CPU type) only supports one CPU, and the realize function of the "fsl,imx31" device also uses serial_hds[] directly, so this device clearly can not be instantiated twice and thus we should mark it with user_creatable = false.

2017-07-24fsl_imx*: Migrate ROM contentsPeter Maydell
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.

2016-07-07i.MX: split the GPT timer implementation into per SOC definitionsJean-Christophe Dubois
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.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
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. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-10-09qdev: Protect device-list-properties against broken devicesMarkus Armbruster
Several devices don't survive object_unref(object_new(T)): they crash or hang during cleanup, or they leave dangling pointers behind. 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.
