缓冲池系统会自动生成,这个生成规律是什么?
例如有一个测试时注意工作的
1.配置缓冲池代码
u32BlkSize = 843264;
stVbConf.u32MaxPoolCnt = 64; //整个系统中可容纳的缓存池个数,即是astCommPool[]缓冲池最多64个,
stVbConf.astCommPool[0].u32BlkSize = u32BlkSize;
stVbConf.astCommPool[0].u32BlkCnt = u32ViChnCnt * 16;
HI_MPI_VB_SetConf(&stVbConf);
2.其他代码工作
8个摄像头->VPSS->在VGA上9分屏显示,最后通过数据回写的方式在VGA内容映射到CVBS(SD0)设备上。
VGA配置是VO_OUTPUT_1366x768_60,
在启动找个测试程序时,cat /proc/umap/vb 查看缓冲池情况如下:
# cat /proc/umap/vb

PoolId=1和PoolId=2缓冲池不是我创建的,这是怎么来的?
我猜测是:id=1缓冲池是VGA显示??id=2是CVBS显示使用吗?
好像没文档说明哪些情况下会自动生成缓冲池,那么我配置缓冲池是否需要注意下不要把MPP的内存分配光,留一点给系统?
1.配置缓冲池代码
u32BlkSize = 843264;
stVbConf.u32MaxPoolCnt = 64; //整个系统中可容纳的缓存池个数,即是astCommPool[]缓冲池最多64个,
