Hello, I've encountered a problem with very slow reading speed from memory allocated by pru kernel driver uio_pruss comparing to reading from usual address spaces. Here is an performance tests on my Beagle Bone black:
Average memcpy from pru DDR start address to application virtual address (300 kB of data): 10.4781ms Average cv::Mat.copyTo (300 kB of data): 11.0681ms Average memcpy from one virtual address to another (300 kB of data): 0.510001ms Kernel version is 4.4.12-bone11 Can somebody explain the issue? May be I should have used new pru rpmesg rproc driver? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
