Linux/AM3352: Processor is working very slow

Rohit Kotak
Intellectual 760 points

Part Number: AM3352
Other Parts Discussed in Thread: AM3359, AM3358

Tool/software: Linux

Hi,

I am using AM3352BZCEA30 based custom board with linux. It seems that it is working very slow. Is there any method to check weather PLL is generating proper (300MHz) frequency or not?

Following are the logs from linux:

root@myboard:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
300000
root@myboard:~#
root@myboard:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
300000

Do I need to configure anything for PLL to generate this frequency?

Regards,

Rohit

    Hi Rohit,

    You can verify DPLL settings with the omapconf tool:

    github.com/.../wiki

    # ./omapconf dump dpll [<dpll>]
    # ./omapconf show dpll [cfg]

    www.ti.com/.../sprac74a.pdf
    3.3.3.2OMAPCONF

    Check also below pointers:

    Hi Pavel,

    The omapconf application helped me a lot to debug many of the MPU registers. Thank you.

    Hi Pavel,

    We are upgrading one product based on AM3352BZCEA30 and our new board seems very slow than the older one. We have upgraded Linux kernel from 3.2 to 4.9 and also we have some more peripherals. AM3352BZCEA30 is same on both the boards.

    we are using below Unix Benchmark utility:
    github.com/.../unixbench-4.1.0

    Below are the logs which shows that our new board is working very slow in comparison of older one:

    --- On old board---
    # ./hanoi 10
    COUNT|43849|1|lps
    # ./dhry2 10
    COUNT|3042003|1|lps

    ---On new board---
    # ./hanoi 10
    COUNT|24627|1|lps
    # ./dhry2 10
    COUNT|1803435|1|lps

    The new board is working on 300MHz:
    # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
    300000

    What are the possible reasons for this bad performance and Is there any way to improve the performance of the board?

    Regards,
    Rohit

    Rohit,

    Do you use kernel 4.9.69 that comes with AM335x PSDK Linux v4.03?

    If yes, I would suggest you to run the benchmark test described in the below user guide and compare the result between two boards:

    software-dl.ti.com/.../Release_Specific_Performance_Guide.html

    software-dl.ti.com/.../Foundational_Components_Kernel_LTP-DDT_Validation.html

    You can also check if using performance governor will make better result:

    www.ti.com/.../sprac74a.pdf - 3.2.1 Dynamic Voltage and Frequency Scaling

    Check also if DDR3 and L3/L4 frequency is the same between 3.2 and 4.9 kernel versions.

    Hi Pavel,

    I found that readout number of BogoMIPS is not as per the frequency on new board:

    root@myboard:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
    300000

    root@myboard:~# cat /proc/cpuinfo
    processor : 0
    model name : ARMv7 Processor rev 2 (v7l)
    BogoMIPS : 149.29
    Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpd32
    CPU implementer : 0x41
    CPU architecture: 7
    CPU variant : 0x3
    CPU part : 0xc08
    CPU revision : 2

    Hardware : Generic AM33XX (Flattened Device Tree)
    Revision : 0000
    Serial : 0000000000000000

    while on older board the value is correct:

    root@4486C1030667:~# cat /proc/cpuinfo
    Processor : ARMv7 Processor rev 2 (v7l)
    BogoMIPS : 298.59

    Revision : 0000
    Serial : 0000000000000000
    root@4486C1030667:~#

    Is this value of BogoMIPS in new board is causing the problem? Why this value differs though we have same processor (AM3352BZCEA30)?

    Rohit,

    Do you use kernel 4.9.69 that comes with AM335x PSDK Linux v4.03?

    When I test PSDK v5.02 (kernel 4.14.79) on AM335x Starter Kit board, BogoMIPS value corresponds to frequency in MHz

    The BogoMIPS value in CPU info should be approximately your clock speed in MHz.

    Hi Pavel,

    I am using yocto build system to build the kernel and recipe fetches the kernel from branch: ti-linux-4.9.y, commit-id: 1e8dbd6794e3c2c32c68d77fcf994c3d0aa1260a

    Yes I understood that BogoMIPS shows approximate value of the clock speed in MHz. Also I found below logs related to OPP using omapconf utility:

    You might get/fetch some kernel that is under development and not ready for release. I would suggest you to get kernel from TI PSDK, as these are official, tested and validated on TI platforms.

    The latest kernel is v4.14.79 and can be get by two methods:

    1. Directly from the PSDK bin file, ti-processor-sdk-linux-am335x-evm-05.02.00.10/board-support/linux-4.14.79+gitAUTOINC+bde58ab01e-gbde58ab01e/

    2. Fetch through Yocto:


    The kernel git repository, branch and commit id can be found below:
    Based on Version: 4.14.79
    URL: git://git.ti.com/processor-sdk/processor-sdk-linux.git
    Branch: processor-sdk-linux-4.14.y
    Commit ID: bde58ab01e3651529680af3eeea7e4d37cb94d40
    If you need to stay with kernel 4.9 you can get it from PSDK 4.x (i.e. 4.03):

    ti-processor-sdk-linux-am335x-evm-04.03.00.05/board-support/linux-4.9.69/

    Or fetch with yocto:

     

    The kernel git repository, branch and commit id can be found below:

    Based on Version: 4.9.69
    URL: git://git.ti.com/processor-sdk/processor-sdk-linux.git
    Branch: processor-sdk-linux-04.03.00

    Hi Pavel,

    I am able to get aprox 300 BogoMIPS using ti-processor-sdk-linux-am335x-evm-05.02.00.10/board-support/linux-4.14.79+gitAUTOINC+bde58ab01e-gbde58ab01e/

    But, facing same issue (BogoMIPS :149.29) with,

    Rohit,

    I tried the pre-built kernel of ti-processor-sdk-linux-am335x-evm-04.03.00.05 and it works fine on AM335x SK board. By default MPU freq is 720MHz, and I am able to switch to 300MHz and BogoMIPS values is fine.

    Notes:
      (1) Module is disabled, rate may not be relevant.

    What is the value you have in CM_CLKSEL_DPLL_MPU/0x44E0042C register? For 720MHz I have 0x00001E00, for 300Mhz I have 0x00001901.

    Yes Pavel, It is working on evmsk for me also but not working with my custom board.

    AM3352BZCEA30 part is used in my custom board while evmsk uses ZCZ package of AM3358 processor.

    Rohit,

    What is your main OSC frequency? On AM335x SK board we have 24MHz.

    Can you also make register dump and compare below registers values between kernel 4.9.69 and 4.14.79, are the values the same?

    CM_AUTOIDLE_DPLL_MPU
    CM_IDLEST_DPLL_MPU
    CM_SSC_DELTAMSTEP_DPLL_MPU
    CM_SSC_MODFREQDIV_DPLL_MPU
    CM_CLKSEL_DPLL_MPU
    CM_CLKMODE_DPLL_MPU
    CM_DIV_M2_DPLL_MPU

    PLL_CLKINPULOW_CTRL

    CM_MPU_CLKSTCTRL
    CM_MPU_CLKCTRL

    Can you also provide me full boot up log from console for kernel 4.9.69, you can put it in txt file and attach here in the forum.

    You can also run the below commands and put the result in this txt file:

    root@am335x-evm:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
    root@am335x-evm:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

    Hi Pavel,

    Please find attached logs (working and not working) where after removing below line from am33xx.dtsi file (in 4.9 kernel source), I am able to get about 300 bogoMIPS with 4.9 kernel:

           ti,syscon-efuse = <&scm_conf 0x7fc 0x1fff 0>;

    With above line, we are able to get bogoMIPS about 300 in starting of boot process but some how it is updated and to 150 afterwords  (which you can find in attached not working logs). While after removing these lines, bogoMIPS is not updated to 150  (which you can find in attached working logs).

    Can you please help me to understand what correct values I should use for ti,syscon-efuse for part (AM3352BZCEA30) which is used in my custom board ?

    Rohit,

    I see you are using kernel 4.9.126, not 4.9.69 that is officially tested and supported. I can suggest you to align to 4.9.69 kernel (that comes with PSDK Linux) as much as you can. You can debug your kernel why below messages appears:

    cpufreq: cpufreq_online: CPU0: Running at unlisted freq: 600000 KHz
    cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP for freq 600000000 (-34)
    cpufreq: cpufreq_online: CPU0: Unlisted initial frequency changed to: 300000 KHz



    ti,syscon-efuse value should be correct for your custom board, there is no other specific value for your custom board. This line is pointing to AM335x Control Module register/bits EFUSE_SMA[12:0] arm_mpu_max_freq. See below pointers:

    AM335x TRM, sections

    1.2.12 Added EFUSE_SMA Register for Help Identifying Different Device Variants

    Hi Pavel,

    I tried with the kernel 4.9.69 (from ti-processor-sdk-linux-am335x-evm-04.03.00.05) but facing same issue. I found the workaround for now is "disable CONFIG_CPUFREQ_DT".

    Regards,

    Rohit
