Hello,
i've this very simple module to test the Resource-Manager.
It just calls ix_rm_init() on module_init() and ix_rm_term()
on module_cleanup().
#include <linux/module.h>
#include <linux/version.h>
#include <linux/kernel.h>
#include <linux/init.h>
#include <linux/types.h>
#include <linux/slab.h>
#include <linux/proc_fs.h>
#include <linux/vmalloc.h>
#include <ix_ossl.h>
#include <ix_rm.h>
#define DBG_ERR KERN_ERR
#define DBG_WARN KERN_WARNING
#define DBG_INFO KERN_INFO
#define DEFAULT_LVL DBG_WARN
#define DBG_LOG(lvl,str,args...) printk(lvl""str, ##args)
#define DBG_MSG(str,args...) DBG_LOG(DEFAULT_LVL, str,##args)
int init_module(void) {
ix_error err;
DBG_MSG("Initializing RM ...\n");
err = ix_rm_init(0);
if(err != IX_SUCCESS) {
DBG_MSG("RM Initialization FAILED.\n");
return err;
}
return 0;
}
void cleanup_module(void) {
ix_error err;
err = ix_rm_term();
if (err != IX_SUCCESS) {
DBG_MSG("RM Termination FAILED.\n");
}
}
If i load this module it bails out with the following message:
Initializing RM ...

Im using the MontaVista-Preview-Kit 3.0 with a kernel-2.4.21-rmk1-ds3.
All the XScale-Support-Libs are loaded.

Has anyone an idea what is wrong?
