hello everyone:
I encounter some troubles when Changing the DVEVM memory map from 64M to 128M(OmapL138 platform,dvsdk_4_02_00_06_omapl138) ,I do this according to the document "Changing the DVEVM memory map"
(http://processors.wiki.ti.com/index.php/Changing_the_DVEVM_memory_map> ):
Platform:OmapL138
DVSDK: (dsplink_1_65_00_02、codec-engine_2_26_02_11)
At first,I use the initial DVEVM memory map :
32M
Linux
0xC0000000 - 0xC1FFFFFF ----------Linux--32M
12 MB
CMEM
0xC2000000 - 0xC2BFFFFF
3 MB
SDRAM (BIOS, Codecs, Applications)
0xC2C00000 - 0xC2EFFFFF
4 KB
DSPLINK (RESET)
0xC2F00000 - 0xC2F0FFFF
1 MB - 4 KB = 1020 KB
DSPLINK (MEM)
0xC2F10000 - 0xC2FFFFFF
16 MB
DDRALGHEAP
0xC3000000 - 0xC3FFFFFF
Test:
I run a application and call Engine_getCpuLoad to get Server's CPU usage in percent.
nearly 70%
Now I want to use the full 128M and I only change the files:
(1)memmap.tci(codecs-omapl138_4_02/packages/ti/sdo/server/cs)
I will change the followings:（below is the initial config）
var mem_ext = [
{
comment: "DDR2: off-chip memory for application code and data",
name: "DDR2",
base: 0xc3200000,
len: 0x00300000,
space: "code/data"
},
{
comment: "RESET_VECTOR: off-chip memory for the reset vector table",
name: "RESET_VECTOR",
base: 0xc3500000,
len: 0x00001000,
space: "code/data"
},
{
comment: "DSPLINK: off-chip memory reserved for DSPLINK code and data",
name: "DSPLINKMEM",
base: 0xc3501000,
len: 0x000FF000,
space: "code/data"
},
{
comment: "DDRALGHEAP: off-chip memory for dynamic algmem allocation",
name: "DDRALGHEAP",
base: 0xc3600000,
len: 0x00A00000,
space: "code/data"
},
];
(2)CFG_OMAPL138GEM_SHMEM.c(dsplink_1_65_00_02/dsplink/config/all)
I will change:
#define RESETCTRLADDR 0xC3E00000
---------------------
Test:
after changing the above files according to my need :
At the condition I call Engine_getCpuLoad to get Server's CPU usage in percent.
nearly 92%
why when I change memory map ,the Server's CPU usage one is 70% and another is 92%(the memory is larger)
and if I still use the 64M of 128M(keeping the same memory as the initial), I only change the address offset(4M) of DSP :
12 MB
CMEM
0xC2000000 - 0xC2BFFFFF
the followings address all add 0x00400000(4M)
3 MB
SDRAM (BIOS, Codecs, Applications)
0xC2C00000 - 0xC2EFFFFF
4 KB
DSPLINK (RESET)
0xC2F00000 - 0xC2F0FFFF
1 MB - 4 KB = 1020 KB
DSPLINK (MEM)
0xC2F10000 - 0xC2FFFFFF
16 MB
DDRALGHEAP
0xC3000000 - 0xC3FFFFFF
and RESETCTRLADDR+4M
but I still get the above result（90%）
I use dsplink_1_65_00_02、codec-engine_2_26_02_11 ,so I the gstreamer cfg file I need not to change.and some steps of the document I passed.
Is there some files I have not change? or?
Why turn out this problem？
Thanks ！
