Other Parts Discussed in Thread: DRA75

Hi expert,

I need to change DRA75 DDR3 size from 1Gbyte to 512Mbyte. I use sdk version is VISION_SDK_02_10_00_00, Linux version 3.14.63, U-Boot 2014.07-00014-g07222a9-dirty (Jun 16 2017 - 16:16:02).

I modify 3 section:

1、modify lisa register, map 512Mbyte to emif1

static const struct dmm_lisa_map_regs lisa_map_dra7_1536MB = {
   .dmm_lisa_map_0 = 0x0,
   .dmm_lisa_map_1 = 0x0,
   .dmm_lisa_map_2 = 0x80500100,
   .dmm_lisa_map_3 = 0xFF020100,
   .is_ma_present   = 0x1
};

2、modify dra7-evm.dts:

    memory {
       device_type = "memory";
       reg = <0x80000000 0x20000000>; /* 512MB */
   };

3、modify uenv.txt mem=512M

when kernel up to starting udev, the log become not normal, as bleow:

Hi,

I have forwarded your question to a kernel expert.
Can you just attach the full log, there might be some clues before the error (if it is too long you can attach it to a post as text file).

Regards,
Yordan

It appears that there is not enough free memory in the system with 512MB memory map - can you please review the memory map requirements to assess if 512MB would suffice. out of the overall memory available in the system some portions are carved out as reserved regions to be accessed from remote cores like the DSP, )IPU etc (firmware loaded to these core, need region of DDR to be carved out for their code, data sections and additionally for IPC mechanism between cores

Also, if CMA memory pool is being used on Linux, some portion of the system memory is also reserved for CMA usage(64MB or so)

Can you attach the complete bootup log information as the memory regions are usually printed as part of the bootup sequence

Hi
from the bootup logs attached, at least 250MB or so is still being carved out for various CMA/reserved mem regions - please review if all of this is completely required - the remaining memory might be too less for running the full system

Hi Srirama,

Thank you for your reply. Follow your advice， I scaled back the size of the reserve，as below:

[    0.000000] Reserved memory: created CMA memory pool at 0x94000000, size 32 MiB
[    0.000000] Reserved memory: initialized node ipu2_cma@95800000, compatible id shared-dma-pool

[    0.000000] Reserved memory: created CMA memory pool at 0x9d000000, size 32 MiB
[    0.000000] Reserved memory: initialized node ipu1_cma@9d000000, compatible id shared-dma-pool
[    0.000000] Reserved memory: created CMA memory pool at 0x9f000000, size 16 MiB

[    0.000000] cma: CMA: reserved 24 MiB at 9b800000

But when it run to starting udev，the log is still not correct, but it's not the same as the previous error.

The full log at this:512_log.txt,

I suspect that the code starting address of DSP and ipu needs to be moved to the low address, but after testing, this address can't be moved, as if it is restricted in any place。I modify the code start address of DSP and ipu at dra7-evm-infoadas.dts, as below:

/* Update the CMA regions for Vision SDK binaries */
&ipu2_cma_pool {
   reg = <0x8C000000 0x2000000>;
};

&dsp1_cma_pool {
   reg = <0x8E000000 0x2000000>;
};

&ipu1_cma_pool {
   reg = <0x90000000 0x2000000>;
};

&dsp2_cma_pool {
   reg = <0x92000000 0x1000000>;
};
I need to add that the usecase I'm using is lvds_vip_multi_cam_3d_srv.

The above question also needs your help to see again, thank you

Hi
Can you please clarify on the intended usecase - have you reviewed if all the concurrent use cases can be fit within 512MB of system memory. The carve out regions being referred to above are mainly used for memory regions allocated for loading code, data , ipc shared memory regions for firmware image loaded to other co-processors in the system. Depending on whether you want to run vision sdk/information adas solution (M4/DSP) and/or Software defined radio(on DSP), you can potentially get rid of unwanted regions.

Overall though if you are using functionality on the co-processor cores , you need to appropriately carve out the required memory regions from Linux. If the co-processor cores are not used, remove the memory region definition and correspondingly ensure that the firmware image is not loaded to the core.

If you want to use the remote cores and still need to cut down on the memory region size, you will have to rebuild the firmware(please confirm first if it can fit and work with the reduced memory allocation) for the new memory map.
