2017-01-27Introduce DEVICE_CATEGORY_CPU for CPU devicesThomas Huth
Now that CPUs show up in the help text of "-device ?", we should group them into an appropriate category.

2016-05-19explicitly include qom/cpu.hPaolo Bonzini
exec/cpu-all.h includes qom/cpu.h. Explicit inclusion will keep things working when cpu.h will not be included indirectly almost everywhere (either directly or through qemu-common.h). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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>
2016-03-04hw/intc/arm_gic.c: Implement GICv2 GICC_DIRPeter Maydell
The GICv2 introduces a new CPU interface register GICC_DIR, which allows an OS to split the "priority drop" and "deactivate interrupt" parts of interrupt completion. Implement this register. (Note that the register is at offset 0x1000 in the CPU interface, which means it is on a different 4K page from all the other registers.)

2013-07-15hw/cpu/a15mpcore: Correct default value for num-irqPeter Maydell
The a15mpcore device claims that its default value for num-irq is the number of interrupts used by the A15MP in the vexpress-a15 board. However that chip has 128 external interrupts, not 64. Since there is only one A15 based model in QEMU currently, we can fix this by simply changing the default value. This error was causing recent (3.10) Linux kernels to print warnings/backtraces when the number of interrupts reported by the GIC was smaller than an interrupt number they wanted to use.
