QOM type names containing ',' result in awful UI. We got rid of them in v6.0.0 (commite178113ff6hw: Replace anti-social QOM type names). A few have crept back since: xlnx,cframe-reg xlnx,efuse xlnx,pmc-efuse-cache xlnx,versal-cfu-apb xlnx,versal-cfu-fdro xlnx,versal-cfu-sfr xlnx,versal-crl xlnx,versal-efuse xlnx,zynqmp-efuse These are all device types. They can't be plugged with -device / device_add, except for "xlnx,efuse" (I'm not sure that one is intentional). They *can* be used with -device / device_add to request help. Usability is poor, though: you have to double the comma, like this: $ qemu-system-aarch64 -device xlnx,,pmc-efuse-cache,help They can also be used with -global, where you must *not* double the comma: $ qemu-system-aarch64 -global xlnx,efuse.drive-index=2 Trap for the unwary. "xlnx,efuse", "xlnx,versal-efuse", "xlnx,pmc-efuse-cache", "xlnx-zynqmp-efuse" are from v6.2.0, "xlnx,versal-crl" is from v7.1.0, and the remainder are new. Rename them all to "xlnx-FOO", like commite178113ff6did.
