Please just add the BCMs for your GPU: .bcms = (const struct a6xx_bcm[]) { { .name = "SH0", .buswidth = 16 }, { .name = "MC0", .buswidth = 4 }, { .name = "ACV", .fixed = true, .perfmode = BIT(3), }, { /* sentinel */ } }; You can factor it out since it's common across many a6xx GPUs and &refer to it from the entry for a620 Konrad
