Nícolas F. R. A. Prado 643a85190a arm64: dts: mediatek: mt8192: Fix CPUs capacity-dmips-mhz ... [ Upstream commit a4366b5695 ] The capacity-dmips-mhz parameter was miscalculated: this SoC runs the first (Cortex-A55) cluster at a maximum of 2000MHz and the second (Cortex-A76) cluster at a maximum of 2200MHz. In order to calculate the right capacity-dmips-mhz, the following test was performed: 1. CPUFREQ governor was set to 'performance' on both clusters 2. Ran dhrystone with 500000000 iterations for 10 times on each cluster 3. Calculated the mean result for each cluster 4. Calculated DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz 5. Scaled results to 1024: result_c0 = dmips_mhz_c0 / dmips_mhz_c1 * 1024 The mean results for this SoC are: Cluster 0 (LITTLE): 12016411 Dhry/s Cluster 1 (BIG): 31702034 Dhry/s The calculated scaled results are: Cluster 0: 426.953226899238 (rounded to 427) Cluster 1: 1024 Fixes: 48489980e2 ("arm64: dts: Add Mediatek SoC MT8192 and evaluation board dts and Makefile") Signed-off-by: Nícolas F.
