ARM Cortex-A17
The ARM Cortex-A17 is a 32-bit processor core implementing the ARMv7-A architecture, licensed by ARM Holdings. Providing up to four cache-coherent cores, it serves as the successor to the Cortex-A9 and replaces the previous ARM Cortex-A12 specifications. ARM claims that the Cortex-A17 core provides 60% higher performance than the Cortex-A9 core, while reducing the power consumption by 20% under the same workload. ARM renamed Cortex-A12 to a variant of Cortex-A17 since the second revision of the A12 core in early 2014, because these two were indistinguishable in  performance and all features available in the A17 were used as upgrades in the A12. New features of the Cortex-A17 specification, not found in the Cortex-A9 specification, are all improvements from the third-generation ARM Cortex-A, which also includes the Cortex-A7 and Cortex-A15: Modern Linux kernel implementations will report and support the above features thus :
