Hi, Denny, The way system test verify edma working is through Crypto performance test which shows the edma interrupt (edma_ccint) increases after the test. The logs are shown below. The generic dmatest is not used and has been removed from top level build. I submitted a jira for it. cat /proc/interrupts CPU0 CPU1 17: 0 0 CBAR 32 Level gp_timer 18: 0 0 GIC-0 29 Level arch_timer 19: 841795 2172460 GIC-0 30 Level arch_timer 22: 0 0 CBAR 4 Level l3-dbg-irq 23: 0 0 WUGEN 10 Level l3-app-irq 25: 1 0 CBAR 232 Level dra7xx-pcie-main 26: 0 0 CBAR 233 Level dra7-pcie-msi 27: 1 0 CBAR 121 Level talert 29: 0 0 CBAR 8 Level omap-dma-engine 32: 1 0 CBAR 361 Level 43300000.edma_ccint 34: 0 0 CBAR 359 Level 43300000.edma_ccerrint root@am57xx-evm:/test# modprobe tcrypt mode=500 sec=1 [80169.707808] [80169.707808] testing speed of async ecb(aes) (ecb-aes-omap) encryption [80169.715773] test 0 (128 bit key, 16 byte blocks): 630707 operations in 1 seconds (10091312 bytes) [80170.722281] test 1 (128 bit key, 64 byte blocks): 331086 operations in 1 seconds (21189504 bytes) [80171.722252] test 2 (128 bit key, 256 byte blocks): 12278 operations in 1 seconds (3143168 bytes) [80172.722120] test 3 (128 bit key, 1024 byte blocks): 7571 operations in 1 seconds (7752704 bytes) [80173.722070] test 4 (128 bit key, 8192 byte blocks): 3628 operations in 1 seconds (29720576 bytes) [80174.722281] test 5 (192 bit key, 16 byte blocks): 598873 operations in 1 seconds (9581968 bytes) [80175.722155] test 6 (192 bit key, 64 byte blocks): 303737 operations in 1 seconds (19439168 bytes) [80176.722243] test 7 (192 bit key, 256 byte blocks): 14753 operations in 1 seconds (3776768 bytes) [80177.722106] test 8 (192 bit key, 1024 byte blocks): 7323 operations in 1 seconds (7498752 bytes) [80178.722058] test 9 (192 bit key, 8192 byte blocks): 2960 operations in 1 seconds (24248320 bytes) [80179.722328] test 10 (256 bit key, 16 byte blocks): 580537 operations in 1 seconds (9288592 bytes) [80180.722168] test 11 (256 bit key, 64 byte blocks): 279123 operations in 1 seconds (17863872 bytes) [80181.722241] test 12 (256 bit key, 256 byte blocks): 8371 operations in 1 seconds (2142976 bytes) [80182.721983] test 13 (256 bit key, 1024 byte blocks): 7175 operations in 1 seconds (7347200 bytes) [80183.721995] test 14 (256 bit key, 8192 byte blocks): 3253 operations in 1 seconds (26648576 bytes) [80184.722237] [80184.722237] testing speed of async ecb(aes) (ecb-aes-omap) decryption (more logs omitted) root@am57xx-evm:/test# cat /proc/interrupts CPU0 CPU1 17: 0 0 CBAR 32 Level gp_timer 18: 0 0 GIC-0 29 Level arch_timer 19: 847049 2178678 GIC-0 30 Level arch_timer 22: 0 0 CBAR 4 Level l3-dbg-irq 23: 0 0 WUGEN 10 Level l3-app-irq 25: 1 0 CBAR 232 Level dra7xx-pcie-main 26: 0 0 CBAR 233 Level dra7-pcie-msi 27: 1 0 CBAR 121 Level talert 29: 0 0 CBAR 8 Level omap-dma-engine 32: 437509 0 CBAR 361 Level 43300000.edma_ccint 34: 0 0 CBAR 359 Level 43300000.edma_ccerrint
