C++ (Cpp) sysInvalidCache Examples

Example #1

File: powerctrl.c Project: LucidOne/Rovio

void pwr_set_clk_profile(int profile)
{
	int i, ticks;
	int old;
	
	if(profile > sizeof(clk_profile)/sizeof(w99702_clk_t)) return;	
	
	cyg_scheduler_lock();
	//HAL_DISABLE_INTERRUPTS(old);
	sysDisableCache();
	sysInvalidCache();
	sysFlushCache(I_D_CACHE);
	sysEnableCache(CACHE_WRITE_BACK);

	
	//outpw(0x3FFF001C, inpw(0x3FFF001C)|0xC);
	//outpw(0x7FF00108, (inpw(0x7FF00108)&(~3))|0x2);

	pwr_set_clk(&clk_profile[profile]);
	
	


	current_clk_profile = profile;	

	//HAL_RESTORE_INTERRUPTS(old);
	cyg_scheduler_unlock();
	
}
