修改cma memory size修改cma memory size 要修改CMA(Contiguous Memory Allocator)的内存大小,通常是在Android操作系统中进行的。CMA被用来管理用于DMA(Direct Memory Access)的连续物理内存区域。以下是一般的步骤: 1. 修改内核参数: * 在`/etc/fstab`文件中添加或修改相应的`android,contiguous-memory-region`条目。
标志的使用及公告制度1．标志的使用(1)通过计量认证的质检机构允许在其出具的检验报告上加盖CMA标志，并在标志下加印计量认证证书编号；(2)通过计量认证和审查认可（验收）的质检机构，允许在其出具的检验报告上加盖CMA标志和CAL标志，并分别在两个标志下加印计量认证和审查认可（验收）的证书编号。(3)...

1、经过分析,发现cma=函数调节没用,因为alignment值是0x2000,0000,即512MB对齐,因此size最低也为512MB,内核配置CONFIG_CMA_SIZE_MBYTES=64,但是实际上没用。 2、由于配置了CONFIG_ZONE_DMA32=y,因此cma分配地址的限制是0x10000,0000,即分配CMA的物理地址不能超过4GB 3、综上所述,当前内核配置最低cma分配的大...
Hello I need to increase the size of the CMA on my armbian set up. But I've not found a way to do it. Is there a kernel command line option I need to pass to increase the CMA size, or is this done in the kernel configuration before building? Thanks in ad
variable step-sizeSummary: This paper analyses the selection of the step-size factor in a new variable step-size constant modulus algorithm (CMA) based on mean square error (MSE) and determines the value range of the step-size factor by computer simulation, which establishes the solid ...
