2008-05-20 04:45:31     a problem about kmalloc()

I use kmallo( ) to  apply about 3K memory in init function of my driver module,  compilation is ok, But when insmod this driver module, the system show:

 

fpga: Unknown symbol _malloc_sizes

insmod: cannot insert 'fpga.ko': Unknown symbol in module (-1): No such file or directory.

 

why? is it kmallo( ) can not apply so large memory ?

Didn't you see any warning when you build the module?

 

You can check "cat /proc/kallsyms | grep malloc_sizes " also "objdump" your module and compare the result.
