Hi CodeAurora, While going through the whole source code by the GitWeb interface (https://www.codeaurora.org/gitweb/quic/la/), there are so many very obscure terms of MSM/QSD chipset in QAEP (MSM/QSD Android Enablement Project) making people stuck out there, who are trying being aware of exactly what they indicate like me, as below. platform/vendor/qcom/msm7625_ffa.git platform/vendor/qcom/msm7625_surf.git platform/vendor/qcom/msm7627_6x.git platform/vendor/qcom/msm7627_7x_ffa.git platform/vendor/qcom/msm7627_7x_surf.git platform/vendor/qcom/msm7627_ffa.git platform/vendor/qcom/msm7627_surf.git platform/vendor/qcom/msm7627a.git platform/vendor/qcom/msm7630_1x_surf.git platform/vendor/qcom/msm7630_ffa.git platform/vendor/qcom/msm7630_fusion.git platform/vendor/qcom/msm7630_surf.git platform/vendor/qcom/msm8660_csfb.git platform/vendor/qcom/msm8660_surf.git platform/vendor/qcom/msm8960.git platform/vendor/qcom/qsd8250_ffa.git platform/vendor/qcom/qsd8250_surf.git platform/vendor/qcom/qsd8650a_st1x.git Therefore, here are couple of questions come up with: 1> What do FFA, SURF and Fusion for MSM/QSD stand for, individually? 2> What features for FFA, SURF and Fusion for MSM/QSD, separately?
