2022-09-04hw/openrisc: Add PCI bus support to virtStafford Horne
This is mostly borrowed from xtensa and riscv as examples. The create_pcie_irq_map swizzle function is almost and exact copy but here we use a single cell interrupt, possibly we can make this generic. Signed-off-by: Stafford Horne <shorne@gmail.com>
2022-09-04hw/openrisc: Add the OpenRISC virtual machineStafford Horne
This patch adds the OpenRISC virtual machine 'virt' for OpenRISC. This platform allows for a convenient CI platform for toolchain, software ports and the OpenRISC linux kernel port. Much of this has been sourced from the m68k and riscv virt platforms. The platform provides: - OpenRISC SMP with up to 4 cpus - A virtio bus with up to 8 devices - Standard ns16550a serial - Goldfish RTC - SiFive TEST device for poweroff and reboot - Generated Device Tree to automatically configure the guest kernel Signed-off-by: Stafford Horne <shorne@gmail.com>
2020-12-15hw/openrisc/openrisc_sim: Use IRQ splitter when connecting IRQ to multiple CPUsPeter Maydell
openrisc_sim_net_init() attempts to connect the IRQ line from the ethernet device to both CPUs in an SMP configuration by simply caling sysbus_connect_irq() for it twice. This doesn't work, because the second connection simply overrides the first. Fix this by creating a TYPE_SPLIT_IRQ to split the IRQ in the SMP case.

2019-03-07kconfig: introduce kconfig filesPaolo Bonzini
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.
