* m68k: add Virtual M68k MachineLaurent Vivier2021-03-151-0/+9
| | | | | | | | | | | | | | The machine is based on Goldfish interfaces defined by Google for Android simulator. It uses Goldfish-rtc (timer and RTC), Goldfish-pic (PIC) and Goldfish-tty (for serial port and early tty). The machine is created with 128 virtio-mmio bus, and they can be used to use serial console, GPU, disk, NIC, HID, ...

* hw/m68k/q800: Don't connect two qemu_irqs directly to the same inputPeter Maydell2020-12-121-0/+1
| | | | | | | | | | | | | | | | | The q800 board code connects both of the IRQ outputs of the ESCC to the same pic[3] qemu_irq. Connecting two qemu_irqs outputs directly to the same input is not valid as it produces subtly wrong behaviour (for instance if both the IRQ lines are high, and then one goes low, the PIC input will see this as a high-to-low transition even though the second IRQ line should still be holding it high). This kind of wiring needs an explicitly created OR gate; add one.

* hw/m68k: define Macintosh Quadra 800Laurent Vivier2019-10-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If you want to test the machine, it doesn't yet boot a MacROM, but you can boot a linux kernel from the command line. You can install your own disk using debian-installer with: ./qemu-system-m68k \ -M q800 \ -serial none -serial mon:stdio \ -m 1000M -drive file=m68k.qcow2,format=qcow2 \ -net nic,model=dp83932,addr=09:00:07:12:34:57 \ -append "console=ttyS0 vga=off" \ -kernel vmlinux-4.15.0-2-m68k \ -initrd initrd.gz \ -drive file=debian-9.0-m68k-NETINST-1.iso \ -drive file=m68k.qcow2,format=qcow2 \ -nographic If you use a graphic adapter instead of "-nographic", you can use "-g" to set the size of the display (I use "-g 1600x800x24").

* hw/m68k: add a dummy SWIM floppy controllerLaurent Vivier2019-10-281-0/+1
| | | | | | | | | | | | | | | | | SWIM (Sander-Wozniak Integrated Machine) is the floppy controller of the 680x0 Macintosh. This patch introduces only the basic support: it allows to switch from IWM (Integrated WOZ Machine) mode to the SWIM mode and makes the linux driver happy. It cannot read any floppy image.

* hw/m68k: add VIA supportLaurent Vivier2019-10-281-0/+4
| | | | | | | | | | | | | | | Inside the 680x0 Macintosh, VIA (Versatile Interface Adapter) is used to interface the keyboard, Mouse, and real-time clock. It also provides control line for the floppy disk driver, video interface, sound circuitry and serial interface. This implementation is based on the MOS6522 object.

* m68k: Add serial controller to the NeXTcube machineThomas Huth2019-09-071-0/+1
| | | | | | | | | | | The NeXTcube uses a normal 8530 serial controller, so we can simply use our normal "escc" device here. While we're at it, also add a boot-serial-test for the next-cube machine, now that the serial output works.

* kconfig: introduce kconfig filesPaolo Bonzini2019-03-071-0/+8
The Kconfig files were generated mostly with this script: for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' ` shift if test $# = 1; then cat >> $(dirname $1)/Kconfig << EOF config ${i#CONFIG_} bool EOF git add $(dirname $1)/Kconfig else echo $i $* fi done sed -i '$d' hw/*/Kconfig for i in hw/*; do if test -d $i && ! test -f $i/Kconfig; then touch $i/Kconfig git add $i/Kconfig fi done Whenever a symbol is referenced from multiple subdirectories, the script prints the list of directories that reference the symbol. These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.
