* x86: Remove the calgary IOMMU driverChristoph Hellwig2019-11-151-57/+0
| | | | | | | | | | | The calgary IOMMU was only used on high-end IBM systems in the early x86_64 age and has no known users left. Remove it to avoid having to touch it for pending changes to the DMA API.

| | | | | | | | | | | | | | | | | | The cal_chipset_ops structures are never modified, so declare them as const. Done with the help of Coccinelle.

* x86, iommu: Make all IOMMU's detection routines return a value.Konrad Rzeszutek Wilk2010-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | We return 1 if the IOMMU has been detected. Zero or an error number if we failed to find it. This is in preperation of using the IOMMU_INIT so that we can detect whether an IOMMU is present. I have not tested this for regression on Calgary, nor on AMD Vi chipsets as I don't have that hardware. CC: Muli Ben-Yehuda <muli@il.ibm.com> CC: "Jon D. Mason" <jdmason@kudzu.us> CC: "Darrick J.

* x86: Calgary: Convert detect_calgary() to use iommu_init hookFUJITA Tomonori2009-11-101-2/+0
| | | | | | | | | | | | | | | | | This changes detect_calgary() to set init_calgary() to iommu_init hook if detect_calgary() finds the Calgary IOMMU. We can kill the code to check if we found the IOMMU in init_calgary() since detect_calgary() sets init_calgary() only when it found the IOMMU.
