10.5, however, requires the later PMU attached to the VIA. 10.3 and 10.4 need to run the emulated mac99 with an emulated CUDA chip onboard, or the OS is unable to detect the real-time clock. The OSes differ on what they prefer for the VIA.
#CUDA EMULATOR MAC MAC OS X#
While QEMU spawns more than four threads, encompassing two cores (i.e., 0-7) has no noticeable performance benefit and can sometimes unsettle Mac OS X by making timing loops unpredictable.įor the -M option, we will specify mac99 and kvm.
This binds all of QEMU's threads to a single core (recall that the T2 Sforza cores are SMT-4, and each appear as logical CPUs, so everything must run on a single core this way). We'll go with 10.4 for our example substitute for your OS of choice where relevant. In addition, we also need to make sure that the emulator stays within a single core for better performance (you will get random system stalls if it moves over to another core and throughput will be generally impaired), so we need to set affinities appropriately. Each OS does better currently with certain combinations of emulated CPU and hardware features.
#CUDA EMULATOR MAC INSTALL#
Let's begin by constructing the command line to boot your emulated Mac from disc and install the OS. I use Netatalk, since I'm more accustomed to AppleTalk and it enables my T2 to serve files over AFP to the other classic Macs here, and it also will work fine with Mac OS 9 if you want to use that at some point. Sudo ip tuntap add dev tap0 mode tap user įor filesharing you could set up either Samba or Netatalk. I'll briefly discuss booting OS 9 with TCG at the end.īefore starting, since we will use tun/tap networking, make sure the interface is up before booting.
#CUDA EMULATOR MAC HOW TO#
I will discuss Leopard relatively little other than how to get you started in it most of the rest applies to Leopard that applies to Tiger. Having followed the instructions in that article, you've got your kernel in hash table mode, you've got the KVM-PR kernel module loaded (and patched it if necessary), you installed (or built) QEMU, and you have a blank QEMU disk image ready to go.įor this part, we will assume you have chosen 10.3 Panther, 10.4 Tiger or 10.5 Leopard to install. In the first part of this article we talked about getting your Talos II prepped to emulate a Power Mac using KVMPPC, the kernel virtualization facility in Linux.
