大家好!
我用的是rdk3.8版本,芯片是8127, 我的DDR是2G的,关于我的config.bld中的内存配置如下:
var LINUX_SIZE = 148*MB
var SR1_SIZE = 100*MB;
var VIDEO_M3_CODE_SIZE = 6*MB;
var VIDEO_M3_DATA_SIZE = 24*MB;
var DSS_M3_CODE_SIZE = 6*MB;
var DSS_M3_DATA_SIZE = 24*MB;
var DSP_CODE_SIZE = 4*MB;
var DSP_DATA_SIZE = 200*MB
var TILER_SIZE = 10*MB; /* Reducing this to fix Vid Frame Alloc failures. Need to fix */ /* MUST be aligned on 128MB boundary */
var SR2_FRAME_BUFFER_SIZE = 465*MB;
var SR0_SIZE = 30*MB;
var HDVPSS_DESC_SIZE = 2*MB;
var HDVPSS_SHARED_SIZE = 2*MB;
var NOTIFY_SHARED_SIZE = 2*MB;
var REMOTE_DEBUG_SIZE = 1*MB;
/* 3rd and 4th 512MB(specific items) */
var LINUX_EXT_SIZE = 512*MB;
var CMEM_SIZE = 512*MB;
当我启动链路后,在开始调用CMEM_alloc()在cmem中申请内存会报错,错误日志如下:
CMEMK Error: ioctl: failed to allocate heap buffer of size 0x330000
CMEMK Error: get_phys: Unable to find phys addr for 0x00000000
CMEMK Error: get_phys: get_user_pages() failed: -14
...
CMEM Debug: alloc: entered w/ size 0x198000, params - type HEAP, flags NONCACHED, align 0x80
CMEM Error: allocHeap: ioctl CMEM_IOCALLOCHEAP failed: -1
CMEM Debug: getPhys: entered w/ addr (nil)
CMEM Error: getPhys: Failed to get physical address of 0
哪位高手能指导下吗?
我的bootargs配置如下:
setenv bootargs 'console=ttyO0,115200n8 lpj=4997120 root=/dev/mtdblock4 rootfstype=jffs2 ro mem=148M mem=512M@0xC0000000 vmalloc=856M vram=20M notifyk.vpssm3_sva=0xbfd00000 cmemk.phys_start=0xE0000000 cmemk.phys_end=0xFFFFFFFF cmemk.allowOverlap=1 earlyprintk'
....另我在调试时发现貌似跟vmalloc这个设置参数有关系,这个值不知道是怎样去计算得到呢?恳请高手指导下.
