The list of unaffected ones are: 0x1308 //kaveri 0x9840 //Kabini 0xaac0 //bonaire 0xaac8 //hawaii 0xaad8 //tonga Pus all newer asics. Alternatively, the list of older asics that are affected (some of these may not even support MSI64 in the first place): 0x1314 //palm 0x7919 //RS690 0x793b //RS600 0x7969 //RS740 0x960f //RS780 0x9646 //sumo 0x970f //RS880 0x9902 //trinity 0xaa00 //R600 0xaa08 //RV630 0xaa10 //RV610 0xaa18 //RV670 0xaa20 //RV635 0xaa28 //RV620 0xaa30 //RV770 0xaa38 //RV730 0xaa40 //RV710 0xaa48 //RV740 0xaa50 //cypress 0xaa58 //juniper 0xaa60 //redwood 0xaa68 //cedar 0xaa80 //cayman 0xaa88 //barts 0xaa90 //turks 0xaa98 //caicos 0xaaa0 //tahiti 0xaab0 //verde, pitcairn, oland It might be better to only set the msi32 flag on the above affected asics so we don't have to worry about new ones.
