-# This is the script I used to use to launch QEMU, emulating
-# Windows 8 with direct physical access to a powerful GPU
-# and the Intel audio controller. This isn't a complete guide,
-# more a collection of tips for any other brave people mad
-# enough to try this. Look up "{VFIO,VGA,GPU,PCI} passthrough"
-# if you want to get proper guidance for this.
-
-# This was working on QEMU 2.12, but note that I'm not updating it anymore.
-
-
-# Create hugepage FS. Don't forget to actually populate it
-# with available RAM using kernel boot arguments or sysctl.
-# The user you run QEMU under (not root!) must be in the kvm group.
-sudo mkdir /dev/hugepages
-sudo mount -t hugetlbfs hugetlbfs /dev/hugepages
-sudo chown root:kvm /dev/hugepages
-sudo chmod 1777 /dev/hugepages # Necessary apparently
-
-
-# The block devices you use for the VM are up to you;
-# mine are at /dev/mapper/win{dows,data}.
-# I recommend refreshing udev after you've created them:
-udevadm trigger

-### USEFUL KERNEL ARGUMENTS
-# intel_iommu=on            : VFIO won't work otherwise. I don't have an AMD CPU,
-#                             but there should be a similar option for that.
-# vfio-pci.ids=XXXX:YYYY,.. : Only available if VFIO is built into the kernel
-#                             (requires custom kernel build). Reserves devices at boot.
-# hugepages=X hugepagesz=Y  : Create X hugepages at boot of size Y ("2M" or "1G").
-# nohugeiomap               : This fixed something, but I can't remember what.
-# intremap=no_x2apic_optout : Some UEFIs don't support the x2apic and disable it.
-#                             This force-enables it. Had no negative consequences for me.
-# pci=pcie_bus_peer2peer    : This was the silver bullet for me, but YMMV.
-# isolcpus=X-Y nohz_full=X-Y rcu_nocbs=X-Y : You MUST use CPU pinning if you add this.
-#                                            X-Y is an inclusive range of CPU cores to
-#                                            to reserve for the vCPUs.

-### MACHINE OPTIONS
-QEMU="-name debug-threads=on -enable-kvm -machine q35,accel=kvm,kernel_irqchip=on,vmport=off,mem-merge=off"
-# -debug-threads=on : name the vCPU threads, useful for CPU pinning.
-# -enable-kvm       : enable KVM acceleration.
-# -machine q35      : emulate the Q35 chipset, which is closer to a modern PC.
-# accel=kvm         : probably identical to -enable-kvm, but just in case.
-# kernel_irqchip=on : emulate an IRQ chip in the kernel instead of in QEMU.
-# vmport=off        : don't emulate a VMWare I/O port.
-# mem-merge=off     : disable KSM, since there is only one VM.
-
-### CPU OPTIONS
-QEMU="$QEMU -cpu host,kvm=off,hv_time,hv_relaxed,hv_spinlocks=0x1fff,hv_vpindex,hv_reset,hv_runtime,hv_crash,hv_vendor_id=NvidiaFix"
-# -cpu host : use the host CPU instead of emulating one.
-# kvm=off   : don't declare self as KVM to the guest, as Windows doesn't care.
-# hv_*      : pretend to be Hyper-V, so Windows can optimize itself for running as a guest.
-# https://www.reddit.com/r/VFIO/comments/479xnx/guests_with_nvidia_gpus_can_enable_hyperv/
-QEMU="$QEMU -smp sockets=1,cores=4,threads=1"
-# -smp ...  : processor layout to emulate.
-
-### RAM OPTIONS
-QEMU="$QEMU -m 12G -mem-path /dev/hugepages -mem-prealloc"
-# -m x          : amount of guest RAM.
-# -mem-path ... : allocate memory from this pool. Can be a file or "hugepages" (mount -t hugetlbfs).
-# -mem-prealloc : allocate all memory from -mem-path at startup rather than on demand.
-
-### EMULATION OPTIONS
-QEMU="$QEMU -vga none -nodefaults -rtc base=utc,clock=host,driftfix=none"
-# -vga none     : don't emulate a graphics card, since we're using a physical one.
-# -nodefaults   : don't emulate any of the default devices.
-# -rtc base=utc : emulate an RTC starting at host's local time.
-# clock=host    : use the host's accurate clock for VM timekeeping.
-# driftfix=none : don't fix Windows' clock drifting, as that involves injecting interrupts.
-QEMU="$QEMU -drive if=pflash,format=raw,file=/usr/share/edk2-ovmf/OVMF_CODE.fd,readonly"
-QEMU="$QEMU -drive if=pflash,format=raw,file=/usr/share/edk2-ovmf/OVMF_VARS.fd"
-# These options enable using the OVMF virtual UEFI instead of SeaBIOS.
-# The exact file locations might vary; this is for Gentoo.
-
-### PCI PASSTHROUGH
-QEMU="$QEMU -device ioh3420,chassis=1,port=1,multifunction=on,bus=pcie.0,addr=1c.0,id=pcie.1"
-# -device ioh3420      : emulate a PCIe I/O hub to attach the GPU to.
-# chassis=1,port=1     : ?
-# bus=pcie.0,addr=1c.0 : place it at 00:1c.0 on the guest.
-# id=pcie.1            : refer to this device as "pcie.1" below.
-QEMU="$QEMU -device vfio-pci,host=04:00.0,multifunction=on,bus=pcie.1,addr=00.0"
-# GPU VGA controller. 
-# multifunction=on     : this device isn't just a VGA controller.
-# bus=pcie.1,addr=00.0 : attach it to the I/O hub as function 0.
-QEMU="$QEMU -device vfio-pci,host=04:00.1,bus=pcie.1,addr=00.1"
-# GPU HDMI audio controller. 
-# bus=pcie.1,addr=00.1 : attach it to the I/O hub as function 1.
-QEMU="$QEMU -device vfio-pci,host=00:1b.0,bus=pcie.0,addr=1b.0"
-# Intel HDA audio controller. 
-# bus=pcie.0,addr=1b.0 : place the device where Intel usually puts its HDA controller.
-
-#QEMU="$QEMU -device intel-iommu,intremap=on"
-# Expose the IOMMU to the guest too. Probably useless in this case.
-
-### USB PASSTHROUGH
-QEMU="$QEMU -usb"
-# Enable USB support.
-QEMU="$QEMU -device usb-host,vendorid=0xXXXX,productid=0xYYYY"
-# If one of these can't be found, it's simply ignored. Use lsusb to find the IDs.
-
-### STORAGE OPTIONS
-QEMU="$QEMU -drive if=ide,format=raw,discard=unmap,detect-zeroes=unmap,file=/dev/mapper/windows"
-QEMU="$QEMU -drive if=ide,format=raw,discard=unmap,detect-zeroes=unmap,file=/dev/mapper/windata"
-# if=ide       : emulate an IDE (SATA) drive. NVMe is possible too, but more of a hassle.
-# format=raw   : talk directly to the drive. Take care: your guest GPT might end up inside a partition.
-# discard=unmap,detect-zeroes=unmap : send discards to the physical device if the guest asks for it.
-# file=x       : backing physical block device.
-
-#QEMU="$QEMU -cdrom ~/Windows.iso"
-# For recovery purposes. I strongly recommend keeping the ISO around.
-
-### NETWORK OPTIONS
-QEMU="$QEMU -netdev user,id=usermode"
-# -netdev user : emulate a user-mode NIC, which is more than fast enough in my experience.
-# id=usermode  : call the interface "usermode"
-QEMU="$QEMU -device e1000,netdev=usermode,mac=88:88:88:88:88:88,bus=pcie.0,addr=19.0"
-# -device e1000        : emulate a gigabit ethernet device.
-# netdev=usermode      : use "usermode" as the host backend.
-# mac=x                : set the MAC address as seen by the guest.
-# bus=pcie.0,addr=19.0 : place the device where Intel usually puts its NIC.
-
-
-# GERONIMO!
-qemu-system-x86_64 $QEMU -daemonize
-# -daemonize : fork once the VM has been initialized.
-
-QEMU_PID=`pidof qemu-system-x86_64`
-echo -e "\033[37;1mQEMU started at PID $QEMU_PID, emulating Windows in Hyper-V mode.\033[m"
-
-sleep 2 # Make sure the VM threads have been spawned.
-
-# Move kernel processes to the housekeeping core (core 0 here).
-#echo 00001 > /sys/bus/workqueue/devices/writeback/cpumask
-#echo 00001 > /sys/bus/workqueue/devices/nvme-wq/cpumask
-
-# Do CPU pinning using "taskset -pc X Y" here,
-# using /proc/$QEMU_PID/task/*/stat to find the thread name.
-# Sorry, my old script for this was so horrible that I don't want to share it.
