hi3536内存问题

海思
 
系统2G的物理内存， mpp_single模式
具体物理内存映射方式  mddrc第0通道管理1GBytes，第1通道管理1GBytes
0x40000000 - 0x60000000 映射到mddrc第0通道（0.5GBytes）
0x60000000 - 0x80000000 映射到mddrc第1通道（0.5GBytes）
0x80000000 - 0xa0000000 映射到mddrc第0通道（0.5GBytes）
0xa0000000 - 0xc0000000 映射到mddrc第1通道（0.5GBytes）

0x40000000 - 0x80000000 分配给内核
0x80000000 - 0xc0000000 分配给mmz
发现mmz只能是用大概0x80000000 - 0xa0000000的地址空间？（0xa0000000 - 0xc0000000管理不到了）

创建4个4k解码通道的时候，会失败（报内存不足的错误），只能创建3个4k！
感觉mddrc可以将内存映射好，mmz应该感觉不到1GBytes的内存是分片的

这个MMZ非常正确， 没有问题， 管理了1G

楼主的问题是 vmap allocation failed， 这个和物理内存没有关系， 是vmalloc的空间不够
其实红字里面已经有解决方法了， 在bootargs 中加 vmalloc=xxxM来解决
