H A D | TESTING | 1 This document contains some hints to test the function of the VCHIQ driver 6 Testing the VCHIQ driver requires a Raspberry Pi with one of the following SoC: 14 There are no specific requirements to the VideoCore firmware to get VCHIQ 26 Just use bcm2835_defconfig which already has VCHIQ enabled. 30 Use the multi_v7_defconfig as a base and then enable all VCHIQ options. 34 Use the defconfig as a base and then enable all VCHIQ options. 40 Check the driver is probed and /dev/vchiq is created
