* hw/boards: Rename no_sdcard -> auto_create_sdcardPhilippe Mathieu-Daudé2025-02-161-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invert the 'no_sdcard' logic, renaming it as the more explicit "auto_create_sdcard". Machines are supposed to create a SD Card drive when this flag is set. In many cases it doesn't make much sense (as boards don't expose SD Card host controller), but this is patch only aims to expose that nonsense; so no logical change intended (mechanical patch using gsed). Most of the changes are: - mc->no_sdcard = ON_OFF_AUTO_OFF; + mc->auto_create_sdcard = true; Except in . hw/core/null-machine.c . hw/arm/xilinx_zynq.c . hw/s390x/s390-virtio-ccw.c where the disabled option is manually removed (since default): - mc->no_sdcard = ON_OFF_AUTO_ON; + mc->auto_create_sdcard = false; - mc->auto_create_sdcard = false; and in system/vl.c we change the 'default_sdcard' type to boolean.

* hw/core/null-machine: Do not initialize unused chardev backendsPhilippe Mathieu-Daudé2020-07-101-0/+5
| | | | | | | | | | | | | | | | | The MachineClass uses an inverted logic (inherited from the PC machines [*]) to create the chardev backends for the default devices (see commits 998bbd74b9d..aa40fc9c964 and ac33f8fad14). As the none-machine doesn't have any hardware device, it is pointless to initialize chardev backends. Fix by setting the 'no_defaults' bits in its MachineClass.

| | | | | | | | | | | | | | | memory_region_allocate_system_memory() API is going away, so replace it with memdev allocated MemoryRegion. The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region.

* Include hw/hw.h exactly where neededMarkus Armbruster2019-08-161-1/+0
| | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

* hw/core: Move null-machine into the common-obj listThomas Huth2018-10-241-1/+1
| | | | | | | | | | | | | The null-machine code used to be target specific since it used the target-specific cpu_init() function in the past. But in the recent commit 2278b93941d42c30e2950 ("Use cpu_create(type) instead of cpu_init(cpu_model)") this has been change, so that the code now uses the common cpu_create() function instead. Thus we can put the null-machine into the common-obj list so that it is compiled only once for all targets, to save some compilation time.

* Use cpu_create(type) instead of cpu_init(cpu_model)Igor Mammedov2018-03-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hw/core/null-machine: Print error message when using the -kernel parameterThomas Huth2017-04-201-0/+6
| | | | | | | | | | | | | | | | If the user currently tries to use the -kernel parameter, simply nothing happens, and the user might get confused that there is nothing loaded to memory, but also no error message has been issued. Since there is no real generic way to load a kernel on all CPU types (but on some targets, the generic loader can be used instead), issue an appropriate error message here now to avoid the possible confusion.

* hw/core/null-machine: Add the possibility to instantiate a CPU and RAMThomas Huth2017-01-231-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | Sometimes it is useful to have just a machine with CPU and RAM, without any further hardware in it, e.g. if you just want to do some instruction debugging for TCG with a remote GDB attached to QEMU, or run some embedded code with the "-semihosting" QEMU parameter. qemu-system-m68k already features a "dummy" machine, and xtensa a "sim" machine for exactly this purpose. All target architectures have nowadays also a "none" machine, which would be a perfect match for this, too - but it currently does not allow to add CPU and RAM yet. Thus let's add these possibilities in a generic way to the "none" machine, too, so that we hopefully do not need additional "dummy" machines in the future anymore (and maybe can also get rid of the already existing "dummy"/"sim" machines one day). Note that the default behaviour of the "none" machine is not changed, i.e. no CPU and no RAM is instantiated by default. You have explicitely got to specify the CPU model with "-cpu" and the amount of RAM with "-m" to get these new features.

* hw: Clean up bogus default boot orderMarkus Armbruster2013-08-281-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.
