Here are the results. For the series: Tested-by: Koichiro Den <[email protected]> * I don't see a significant difference between Before and After, but I don't think that is an issue at all. Most of the differences look like normal run-to-run variation. * Each full fio test set was run three times in alternating order (B-A-B-A-B-A), with runtime=30s and ramp_time=5s. eDMA: - Testbed: * Endpoint: RK3588 (Rock 5B) controller IP version: v5.60a ll_max: 170 - Summary by group (BW delta %) all n=26 mean= -2.3 median= +0.2 min= -28.0 max= +11.7 read n=14 mean= -3.2 median= +0.2 min= -17.3 max= +3.1 write n=11 mean= -1.5 median= -0.2 min= -28.0 max= +11.7 qd32 n=16 mean= +0.5 median= +0.3 min= -3.8 max= +3.1 q1 n= 9 mean= -7.6 median= -6.7 min= -28.0 max= +11.7 small 4K n= 6 mean= -4.0 median= +1.1 min= -28.0 max= +3.1 large >=128K n=20 mean= -1.8 median= +0.1 min= -17.3 max= +11.7 - Before mean -> After mean (MiB/s) Case Before After Delta --------------------------- ----------------- ----------------- ------ Rnd read 4KB q1 1j 33.4 (sd 10.1) 32.0 (sd 10.9) -4.0% Rnd read 4KB q32 1j 196.0 (sd 28.6) 202.0 (sd 29.5) +3.1% Rnd read 4KB q32 4j 196.7 (sd 29.2) 202.0 (sd 25.1) +2.7% Rnd read 128KB q1 1j 497.7 (sd 12.2) 420.7 (sd 181.3) -15.5% Rnd read 128KB q32 1j 2248.0 (sd 6.6) 2277.3 (sd 34.2) +1.3% Rnd read 128KB q32 4j 2381.3 (sd 2.5) 2386.3 (sd 17.9) +0.2% Rnd read 512KB q1 1j 627.3 (sd 15.2) 585.3 (sd 78.2) -6.7% Rnd read 512KB q32 1j 2376.0 (sd 5.2) 2381.3 (sd 21.4) +0.2% Rnd read 512KB q32 4j 2379.7 (sd 6.7) 2386.7 (sd 17.6) +0.3% Rnd write 4KB q1 1j 28.1 (sd 4.1) 20.2 (sd 10.1) -28.0% Rnd write 4KB q32 1j 120.3 (sd 6.1) 122.0 (sd 6.2) +1.4% Rnd write 4KB q32 4j 124.7 (sd 3.8) 125.7 (sd 4.6) +0.8% Rnd write 128KB q1 1j 318.7 (sd 44.7) 327.0 (sd 4.4) +2.6% Rnd write 128KB q32 1j 1080.0 (sd 20.2) 1077.3 (sd 37.6) -0.2% Rnd write 128KB q32 4j 1069.7 (sd 20.3) 1056.0 (sd 46.2) -1.3% Seq read 128KB q1 1j 486.3 (sd 138.3) 402.3 (sd 38.0) -17.3% Seq read 128KB q32 1j 2245.3 (sd 3.5) 2258.7 (sd 26.3) +0.6% Seq read 512KB q1 1j 662.0 (sd 29.2) 594.3 (sd 13.7) -10.2% Seq read 512KB q32 1j 2375.7 (sd 7.4) 2382.0 (sd 22.9) +0.3% Seq read 1MB q32 1j 2380.7 (sd 4.7) 2385.3 (sd 19.3) +0.2% Seq write 128KB q1 1j 342.0 (sd 58.9) 382.0 (sd 101.1) +11.7% Seq write 128KB q32 1j 1080.3 (sd 48.8) 1070.7 (sd 37.0) -0.9% Seq write 512KB q1 1j 509.7 (sd 35.4) 502.7 (sd 39.2) -1.4% Seq write 512KB q32 1j 1043.3 (sd 56.7) 1074.0 (sd 47.8) +2.9% Seq write 1MB q32 1j 989.3 (sd 23.0) 952.0 (sd 57.4) -3.8% Rnd rdwr 4K..1MB q8 4j 841.3 (sd 15.1) 841.7 (sd 12.9) +0.0% HDMA: - Testbed: * Endpoint: SpacemiT K3 controller IP version: v6.30a ll_max: 170 - Summary by group (BW delta %) all n=26 mean= +1.1 median= -0.6 min= -4.4 max= +9.5 read n=14 mean= +2.1 median= +0.7 min= -2.5 max= +9.5 write n=11 mean= -0.1 median= -0.8 min= -4.4 max= +4.7 qd32 n=16 mean= +0.6 median= -0.8 min= -2.5 max= +9.5 q1 n= 9 mean= +2.0 median= +4.4 min= -4.4 max= +7.9 small 4K n= 6 mean= +4.8 median= +4.5 min= +0.2 max= +9.5 large >=128K n=20 mean= -0.0 median= -0.9 min= -4.4 max= +7.9 - Before mean -> After mean (MiB/s) Case Before After Delta --------------------------- ----------------- ----------------- ------ Rnd read 4KB q1 1j 66.3 (sd 5.8) 69.4 (sd 7.0) +4.6% Rnd read 4KB q32 1j 300.3 (sd 45.5) 329.0 (sd 21.7) +9.5% Rnd read 4KB q32 4j 312.0 (sd 51.1) 341.7 (sd 3.1) +9.5% Rnd read 128KB q1 1j 705.7 (sd 34.8) 736.7 (sd 51.6) +4.4% Rnd read 128KB q32 1j 1507.7 (sd 25.6) 1486.3 (sd 5.9) -1.4% Rnd read 128KB q32 4j 1549.7 (sd 7.0) 1534.3 (sd 16.9) -1.0% Rnd read 512KB q1 1j 848.7 (sd 9.5) 858.0 (sd 15.5) +1.1% Rnd read 512KB q32 1j 1530.0 (sd 27.0) 1536.0 (sd 14.8) +0.4% Rnd read 512KB q32 4j 1519.0 (sd 66.7) 1544.3 (sd 15.0) +1.7% Rnd write 4KB q1 1j 64.0 (sd 6.2) 66.9 (sd 2.2) +4.5% Rnd write 4KB q32 1j 199.3 (sd 7.1) 199.7 (sd 2.9) +0.2% Rnd write 4KB q32 4j 199.7 (sd 7.6) 200.3 (sd 3.2) +0.3% Rnd write 128KB q1 1j 558.3 (sd 18.3) 533.7 (sd 5.0) -4.4% Rnd write 128KB q32 1j 1248.0 (sd 21.3) 1237.3 (sd 7.5) -0.9% Rnd write 128KB q32 4j 1248.7 (sd 23.0) 1238.0 (sd 6.1) -0.9% Seq read 128KB q1 1j 640.7 (sd 60.1) 691.3 (sd 9.0) +7.9% Seq read 128KB q32 1j 1507.7 (sd 24.2) 1488.3 (sd 5.1) -1.3% Seq read 512KB q1 1j 866.7 (sd 45.8) 847.0 (sd 32.2) -2.3% Seq read 512KB q32 1j 1532.3 (sd 31.7) 1516.7 (sd 40.3) -1.0% Seq read 1MB q32 1j 1550.7 (sd 7.2) 1512.0 (sd 32.9) -2.5% Seq write 128KB q1 1j 514.0 (sd 34.7) 538.0 (sd 15.1) +4.7% Seq write 128KB q32 1j 1248.0 (sd 22.1) 1237.0 (sd 7.8) -0.9% Seq write 512KB q1 1j 755.7 (sd 30.0) 739.3 (sd 2.1) -2.2% Seq write 512KB q32 1j 1248.7 (sd 22.6) 1238.3 (sd 6.7) -0.8% Seq write 1MB q32 1j 1248.0 (sd 22.5) 1238.3 (sd 7.6) -0.8% Rnd rdwr 4K..1MB q8 4j 869.0 (sd 8.9) 865.3 (sd 1.5) -0.4% Best regards, Koichiro > > Best regards, > Koichiro > > > > > Rebase and compile test only now. > > > > Verma, Devendra: > > Can you help check if block non-ll mode?
