Re: [RFC] [Patch] calgary iommu: Use the first kernel's tce tables in kdump

Hi Muli,

I have tried to work with CCR ,CSR, CSMR, CSAR, CFGRW, GBRERRMregisters but have been unable to make calgary generate an exceptionupon error condition. In alloc_tce_table() , I am setting WRITE_ONLYaccess permission bit to tce entries but it isn't helping. Would youkindly let me know how we can make calgary to generate an exception inerror conditions ?.


Thanks,
Chandru
