vdec_attr.u32FrameBufCnt与vdec_attr.u32StreamBufCnt这两个参数配置有没有啥标准或者参考依据的，测试发现当解码到8192*8192的时候，如果要多通道这两个参数只能设置为1
你好，我是地平线研发。
1. 解码器最大支持8192*8192分辨率
2. u32FrameBufCnt和u32StreamBufCnt有如下配置要求：
a) u32FrameBufCnt 取值范围是 [1，31]，默认值是5
b) u32StreamBufCnt取值范围是[1，65536]，默认值是5
3. 解码到8192*8192的时候，如果要多通道这两个参数只能设置为1。
原因：这个大概率是ion内存分配不出来了，因为图片尺寸很大时候，需要的内存就很大。建议将解码分辨率改小试试。
另外，如果解码分辨率不变，而又想这增加这两个参数，就需要增大ion内存。有两种方式：
a) 尝试修改内核dts
b) uboot方式尝试修改：
i> 接入串口，进入到uboot阶段
ii> setenv ion_size 1024 #这里是修改为1G，可以尝试再增大一些
iii> saveenv
然后重启开发板后，通过命令memstate查看 cma-reserved内存是否增加了。
感谢您的回复，有个问题是在解码jpeg 8192x8192分辨率的图片时，第一次第一帧解码send和get数据耗时比较大，有时候get超时设置30-40s还没有获取到数据，只能设置为-1无限超时，但是后面再次解码就会比较快，大概150ms，请问这个什么原因，解决办法？
你好，帮忙抓些log，给我们分析。在运行程序之前，在终端输入以下的命令，然后将运行的log保持下来。
a) export LOGLEVEL=14 #这句是打开运行的应用debug log
b) echo “file hobot_vpu_dev.c +p” >/sys/kernel/debug/dynamic_debug/control #打开vpu内核调试log
最后，运行过程中，将dmesg的内核log也存一下。
root@x3sdbx3-samsung2G-3200:/userdata# export LOGLEVEL=14

我是读取一张8192x8192的jpeg循环解码50次，前面24次都是超时的，只有后面26次是正常解码的，我现在测试的时候send和get设置的超时时间都说1000ms。
你好，这个应该是cma内存不够引起的。
在终端下输入以下命令：
a) mount -o remount,rw /
b) vi /etc/init.d/load_ko.sh 脚本最前面加入
echo 672 > /sys/class/misc/ion/cma_carveout_size
c) 然后reboot重启。
d) 重启后，输入 cat /sys/class/misc/ion/cma_carveout_size，如果修改成功，下面会显示672
e) 然后开始你的测试，看看能不能成功。
感谢您的回复，我这边会修改后测试，可能要一段时间做稳定性测试才能给出测试结果，想请问下这个修改参数的设置有什么依据范围，或者有没有什么参考文档可以介绍的，修改后对系统有没有什么影响。
另外是否方便告知一下您这边的联系方法，方便比较快捷有效的沟通问题，官方的邮箱基本不怎么回复问题的?
测试发现一个问题，修改这个脚本后发现有的时候reboot重启这个内存值为0，有的时候reboot为672，没有什么规律，不知道是不是没有永久生效
你好，值为0说明设置不成功。
cma要求是连续的物理内存。在linux内核启动过程中，有些内存用过动态申请的位置的随机性，可能造成cma搬移不成功。
672M可能正好是一个临界值，建议设置小一些。
我这边会通知社区的负责人，看后面怎么沟通方便。
pdhat用户您好：问答需要放在社区，虽然慢点，但是不会影响到研发人员的正常工作，研发人员在空余时间登录论坛，回复并解决问题。否则很折腾，很牵扯研发人员的精力。-
为了快速沟通，您可以把问题全面的写出来，保证研发人员可以快速的理解并回复。
@yong.wu，感谢回复，想问下这个设置小于672M是不是会每次重启生效呢，这个设置672m重启有时候没有生效没有规律可能会对系统不稳定的
你好。你设置小一点，应该会每次都会生效的。可以多次修改尝试后确定。
