imx6

I am working on IMX6QP with yocto rocko / Linux 4.14.24 and I am trying to use the GPU. My yocto configuration file : MACHINE ??= 'imx6qp-tx6-emmc' DL_DIR ?= "${BSPDIR}/downloads" SSTATE_DIR ?= "${BSPDIR}/sstate-cache" DISTRO ?= 'karo-minimal' PACKAGE_CLASSES ?= "package_deb" EXTRA_IMAGE_FEATURES ?= "debug-tweaks" VIRTUAL-RUNTIME_init_manager = "sysvinit" USER_CLASSES ?= "buildstats image-mklibs image-prelink" PATCHRESOLVE = "noop" BB_DISKMON_DIRS ??= "\ STOPTASKS,${TMPDIR},1G,100K \ STOPTASKS,${DL_DIR},1G,100K \ STOPTASKS,${SSTATE_DIR},1G,100K \ STOPTASKS,/tmp,100M,100K \ ABORT,${TMPDIR},100M

Goal: emulate the "sabrelite : Freescale i.MX6 Quad SABRE Lite Board (Cortex A9)" that Qemu specifically supports (doing 'qemu-system-arm -M ?' it shows up). Qemu ver: 2.10.1 (host: fedora-27). I have successfully cross-compiled and built a 4.1.46 Linux kernel (used the imx_v6_v7_defconfig config file) as well as a simple "skeleton" root filesystem (busybox-based). (FYI, I have a similar working setup for the ARM Cortex-A9 Versatile Express platform - I do this using my own home-spun embedded Linux system called SEALS ). Looking at the U-Boot config file used by similar boards, I figured to
