Ich muss mir unbedingt merken, dass die langsame Reaktion auf IPIs, die in QEMU KVM nicht über Hypercalls ausgelöst werden, die Performance katastrophal beeinträchtigen kann, wenn ich das nächste Mal einen Kernel mit QEMU als Zielsystem schreibe. Mir graut es davor, herauszufinden, ob QEMU MTTCG ähnlich betroffen ist, da es im Mainline-QEMU keine solche Hypercalls gibt.

I need to make a mental note of the fact that slow responsiveness to IPIs not issued via hypercall in qemu KVM can pathologically degrade performance for the next time I'm writing a kernel using qemu as a target system. I'm terrified of finding out whether qemu MTTCG is similarly affected, because it has no such hypercalls in mainline qemu.

Virtualisation on Apple silicon Macs is different

🔓 Two years after launch Black Myth: Wukong lost its main shield: hacker voices38 reportedly bypassed Denuvo and a full CRACK has appeared online.

Researcher Maurice Hoyman earlier claimed a bypass «without a hypervisor» but didn't publish files; now the full crack is circulating thanks to the Hypervisor method. Wukong joins Resident Evil Requiem and Doom: The Dark Ages, another sign that modern DRM is brittle.
