Enable smp with imx8qm(optee: 3.8.0 linux:4.14 arm64 )，bring up all cpus successfuly, but kernel oops with kernel page fault

[chenlifu2015]

hi，experts
I have successfully loaded optee os on imx8qm with android version 9.0，also I have use early avb ta in uboot to implement avb function, but There ara some oops happeded during bootimg loaded,I check the log,and I found that when Linux bring up the secondary CPUs by smp successfully, but sames like some pci setting up are not right, oops with kernel page fault:
call traces are as follows, and When I use trusty os instead of optee os, the kermel works fine:

Hi @chenlifu2015 ,

Perhaps there is a memory conflict between the kernel and OP-TEE (code, data and/or shared memory). Have you checked your DT? Is OP-TEE built with CFG_DT=y?

[chenlifu2015]

hi，jforissier
Thanks for your apply , I have add the optee memory node in relative dtb file. content is as follows,Can you help me check the content? I add those content according to the imx8qm
firmware {
optee {
compatible = "linaro,optee-tz";
method = "smc";
};
};
optee_core: optee_core@FE000000
{
reg = <0 0xFE000000 0 0x01E00000>;
no-map;
};
optee_shm: optee_shm@0xFFE00000
{
reg = <0 0xFFE00000 0 0x00200000>;
no-map;
};
but I got the some oops:

@MrVan, If I have reserved the memory for optee in the function:dram_init. using the following code:
if (!rom_pointer[1])
return 0;
gd->ram_size = gd->ram_size - rom_pointer[1];
After that, is there any necessary to add optee memory node in Linux dts file?

[MrVan]

@chenlifu2015 which U-Boot version are u using? NXP released U-Boot will automatically create optee node

[chenlifu2015]

@MrVan My uboot version is 2018.03-dirty, kernel version is 4.14.98-07190-gbcdaf61-dirty,with the NXP Android 9 SDK,now I have loaded optee os(version 3.8.0) successfully,and also enabled avb early ta so uboot can use avb ta to verify vbmeta.img,my boot sequence is :
spl--->bl31--->optee os--->bl33(u-boot)---->boot.img, but when optee os switch to normal world booting, uboot is successfully loaded, and avb feature is working fine, but when kernel loaded, oops happed, I have reserved the memory for optee in uboot, so there is no way th have memory confilct between kernel and optee os.so I want to know how to solve the kernel oops. because when I use trusty os without optee os, kernel works fine,
