2024-02-27hw/core: Add ResetContainer which holds objects implementing ResettablePeter Maydell
Implement a ResetContainer. This is a subclass of Object, and it implements the Resettable interface. The container holds a list of arbitrary other objects which implement Resettable, and when the container is reset, all the objects it contains are also reset. This will allow us to have a 3-phase-reset equivalent of the old qemu_register_reset() API: we will have a single "simulation reset" top level ResetContainer, and objects in it are the equivalent of the old QEMUResetHandler functions. The qemu_register_reset() API manages its list of callbacks using a QTAILQ, but here we use a GPtrArray for our list of Resettable children: we expect the "remove" operation (which will need to do an iteration through the list) to be fairly uncommon, and we get simpler code with fewer memory allocations. Since there is currently no listed owner in MAINTAINERS for the existing reset-related source files, create a new section for them, and add these new files there also.

2023-06-20meson: Replace softmmu_ss -> system_ssPhilippe Mathieu-Daudé
We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation. Mechanical change doing: $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230613133347.82210-10-philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-05-16hw/core: Move machine-qmp-cmds.c into the target independent source setThomas Huth
The only target specific code that is left in here are two spots that use TARGET_NAME. Change them to use the new target_name() wrapper function instead, so we can move the file into the common softmmu_ss source set. That way we only have to compile this file once, and not for each target anymore. Message-Id: <20230424160434.331175-4-thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
2023-04-20hw/core: Move numa.c into the target independent source setThomas Huth
There is nothing that depends on target specific macros in this file, so we can move it to the common source set to avoid that we have to compile this file multiple times (one time for each target).

2021-11-01hw/core/machine: Split out the smp parsing codeYanan Wang
We are going to introduce an unit test for the parser smp_parse() in hw/core/machine.c, but now machine.c is only built in softmmu. In order to solve the build dependency on the smp parsing code and avoid building unrelated stuff for the unit tests, move the tested code from machine.c into a separate file, i.e., machine-smp.c and build it in common field.

2021-03-10hw/core: implement a guest-loader to support static hypervisor guestsAlex Bennée
Hypervisors, especially type-1 ones, need the firmware/bootcode to put their initial guest somewhere in memory and pass the information to it via platform data. The guest-loader is modelled after the generic loader for exactly this sort of purpose: $QEMU $ARGS -kernel ~/xen.git/xen/xen \ -append "dom0_mem=1G,max:1G loglvl=all guest_loglvl=all" \ -device guest-loader,addr=0x42000000,kernel=Image,bootargs="root=/dev/sda2 ro console=hvc0 earlyprintk=xen" \ -device guest-loader,addr=0x47000000,initrd=rootfs.cpio Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210303173642.3805-5-alex.bennee@linaro.org>
