2024-10-03hw/char: Extract serial-mmBernhard Beschow1-5/+5
hw/char/serial currently contains the implementation of both TYPE_SERIAL and TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's move the latter into its own module which makes the dependencies more obvious and the code more tidy. The includes and the dependencies have been converted mechanically except in the hw/char directories which were updated manually. The result was compile-tested. Now, only hw/char makes direct use of TYPE_SERIAL: # grep -r -e "select SERIAL" | grep -v SERIAL_ hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL # grep -r -e "/serial\\.h" include/hw/char/serial-mm.h:#include "hw/char/serial.h" hw/char/serial-pci-multi.c:#include "hw/char/serial.h" hw/char/serial.c:#include "hw/char/serial.h" hw/char/serial-isa.c:#include "hw/char/serial.h" hw/char/serial-pci.c:#include "hw/char/serial.h" Tested-by: Andrew Jeffery <andrew@codeconstruct.com.au> Reviewed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Bernhard Beschow <shentey@gmail.com> Link: https://lore.kernel.org/r/20240905073832.16222-4-shentey@gmail.com Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2024-05-10kconfig: express dependency of individual boards on libfdtPaolo Bonzini1-1/+2
Now that boards are enabled by default and the "CONFIG_FOO=y" entries are gone from configs/devices/, there cannot be any more a conflicts between the default contents of configs/devices/ and a failed "depends on" clause. With this change, each individual board or target can express whether it needs FDT. It can then include the common code in the build via "select DEVICE_TREE", which will also as tell meson to link with libfdt. This allows building non-microvm x86 emulators without having libfdt available. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-05-03mips: switch boards to "default y"Paolo Bonzini1-0/+12
Some targets use "default y" for boards to filter out those that require TCG. For consistency we are switching all other targets to do the same. Continue with MIPS. No changes to generated config-devices.mak file. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-03-08mips: do not list individual devices from configs/Paolo Bonzini1-1/+19
Add new "select" and "imply" directives if needed. The resulting config-devices.mak files are the same as before. Builds without default devices will become much smaller than before, and qtests fail (as expected, though suboptimal) for mips64-softmmu because most tests do not use -nodefaults, so remove it from build-without-defaults Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-01-04hw/mips: Add Loongson-3 machine supportHuacai Chen1-0/+12
Add Loongson-3 based machine support, it use liointc as the interrupt controler and use GPEX as the pci controller. Currently it can work with both TCG and KVM. As the machine model is not based on any exiting physical hardware, the name of the machine is "loongson3-virt". It may be superseded in future by a real machine model. If this happens, then a regular deprecation procedure shall occur for "loongson3-virt" machine. We now already have a full functional Linux kernel (based on Linux-5.4.x LTS) here: https://github.com/chenhuacai/linux Of course the upstream kernel is also usable (the kvm host side and guest side have both been upstream in Linux-5.9): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git How to use QEMU/Loongson-3? 1, Download kernel source from the above URL; 2, Build a kernel with arch/mips/configs/loongson3_defconfig; 3, Boot a Loongson-3A4000 host with this kernel (for KVM mode); 4, Build QEMU-master with this patchset; 5, modprobe kvm (only necessary for KVM mode); 6, Use QEMU with TCG: qemu-system-mips64el -M loongson3-virt,accel=tcg -cpu Loongson-3A1000 -kernel <path_to_kernel> -append ... Use QEMU with KVM: qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel <path_to_kernel> -append ... The "-cpu" parameter is optional here and QEMU will use the correct type for TCG/KVM automatically.

Currently, isa-superio.c is always compiled as soon as CONFIG_ISA_BUS is enabled. But there are also machines that have an ISA BUS without any of the superio chips attached to it, so we should not compile isa-superio.c in case we only compile a QEMU for such a machine. Thus add a proper CONFIG_ISA_SUPERIO switch so that this file only gets compiled when we really, really need it.
