Your loadmodules.sh shows you giving 12MB to CMEM (although the insmod line
appears to be commented out). This amount will satisfy your specified needs of
My memory req are like
pool fitting a size 4147200
pool fitting a size 8294400
although enough for only one of each. However, you are partitioning the 12MB
with too many pools/buffers to allow your allocations to succeed. Try
specifying:
pools=1x8294400,1x4147200
If you need more than just those two buffers, you will need to give less memory
to Linux and more to CMEM. Linux kernel memory is specified on the boot
command. With your given loadmodules.sh, you would need to be specifying
mem=116M at a maximum, and to give more to CMEM you would need to specify less
than 116M.

Hi,
Since i am new to linux can u let me know how i can exchange memory with linux .
My loadmodules.sh script looks like
#!/bin/sh
# 12MB
# insmod cmemk.ko phys_start=0x87400000 phys_end=0x88000000
pools=1x2097152,2x1529856,7x829440,1x524288,1x108680,1x81920,2x8192,6x4096
./mapdmaq
insmod dm350mmap.ko
rm -f /dev/dm350mmap
mknod /dev/dm350mmap c `awk "\\$2==\"dm350mmap\" {print \\$1}" /proc/devices` 0
My memory req are like
pool fitting a size 4147200
pool fitting a size 8294400
Regard's
