This comment is not accurate since a while, IIUC: Up to q35-2.7: 255 q35-2.8: 288 q35-8.0+: 1024 q35-9.0: 4096 > QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL > VGA BIOS.

Since the Q35's 4096 CPUs change will be stated in the v9.0 release, I doubt we should synchronize the doc update (so I added the "for-v9.0?" tag to throw this question out). Thanks, Zhao
