/proc/cpuinfo on the three Qualcomm MSM platforms I have convenient gives: The Hardware string on the last one is my device tree work, it's on an MSM8660 FLUID (http://www.bsquare.com/snapdragon-mobile-development-platform.aspx) ---------------------------------------------------------------------- Processor : ARMv7 Processor rev 1 (v7l) processor : 0 BogoMIPS : 13.53 processor : 1 BogoMIPS : 13.53 Features : swp half thumb fastmult vfp edsp neon vfpv3 CPU implementer : 0x51 CPU architecture: 7 CPU variant : 0x0 CPU part : 0x04d CPU revision : 1 Hardware : QCT MSM8960 CDP Revision : 0000 Serial : 0000000000000000 ---------------------------------------------------------------------- Processor : ARMv7 Processor rev 1 (v7l) BogoMIPS : 191.69 Features : swp half thumb fastmult vfp edsp neon vfpv3 CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc05 CPU revision : 1 Hardware : QCT MSM9615 CDP Revision : 0000 Serial : 0000000000000000 ---------------------------------------------------------------------- Processor : ARMv7 Processor rev 2 (v7l) processor : 0 BogoMIPS : 501.35 processor : 1 BogoMIPS : 209.30 Features : swp half thumb fastmult vfp edsp neon tls CPU implementer : 0x51 CPU architecture: 7 CPU variant : 0x0 CPU part : 0x02d CPU revision : 2 Hardware : Qualcomm MSM (Flattened Device Tree) Revision : 0000 Serial : 0000000000000000 ---------------------------------------------------------------------- -- Sent by an employee of the Qualcomm Innovation Center, Inc.
