Hi,

I have a problem with MSI Interrupt. C6678 read the Message Address(0xFEEFF00C) and Message Data(0X000049A0) from register,and translate the Message Address to DSP pci space region 0 0x606ff00c,the OB_OFFSET_INDEX0 = 0xFE800000,and write the Message data to 0x606ff00c.The Host listen the interrupt by windriver ,but the windriver can not receive the interrupt.I do not known how to solve this problem.
