The imx6 cpufreq driver reads the "speed grading" fuses in order to determine what are the operating frequencies that will be populated, so what you see is the normal behavior. On a different topic: I remember you have been trying Etnaviv with linux-fslc. One suggestion I could give you regarding performance is to drop the CONFIG_PROVE_LOCKING=y option from imx_v6_v7_deffconfig. Hope this helps. -- _______________________________________________ meta-freescale mailing list meta-freescale@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-freescale
