Hello friends! I using the Khadas VIM3 SBC with Amlogic A311D device. When I resuming after "echo mem > /sys/power/state" my system is very and very slow, more than 5 times slowing. CPU frequensies throght sysfs are similars for before suspend and after resume VIM3 ~ # cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq 1800000 VIM3 ~ # cat /sys/devices/system/cpu/cpufreq/policy2/cpuinfo_cur_freq 2208000 VIM3 ~ # echo mem > /sys/power/state VIM3 ~ # cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq 1800000 VIM3 ~ # cat /sys/devices/system/cpu/cpufreq/policy2/cpuinfo_cur_freq 2208000 VIM3 ~ # However in uart console log I recieve such message: bl30 get wakeup sources! process command 00000006 bl30 enter suspend! Little core clk suspend rate 1800000000 Big core clk suspend rate 24000000 store restore gp0 pll suspend_counter: 1 Enter ddr suspend DMC_DRAM_STAT11: 0x544 ddr suspend time: 2177us alarm=0S process command 00000001 cec ver:2018/04/29 CEC cfg:0x0000 use vddee new table! use vddee new table! exit_reason:0x06 Enter ddr resume DMC_DRAM_STAT3: 0x544 ddr resume time: 3187us store restore gp0 pll cfg15 3b00000 cfg15 63b00000 Little core clk resume rate 1800000000 Big core clk resume rate 50000000 login: timed out after 60 seconds Arch Linux 5.19.0-rc2-ARCH+ (ttyAML0) VIM3 login: I'm not sure, but I think what the "Big core clk resume rate too small for Amlogic A311D and therefore my system is very slow. Is there any way to fix this?
