swiotlb detection should be memory hotplug aware ?
Hi, Reviving a 4 month old thread. I am still waiting for any clues on this question below. 2. Instead of checking the max_pfn value in pci_swiotlb_detect, check for max_hotpluggable_pfn (or some such) value. Though I don't see such a value readily available. I could parse the SRAT and get hotplug ... 28 Jul 2010 10:45

mm: iommu: An API to unify IOMMU, CPU and device memory management
Russell- If a driver wants to allow a device to access memory (and cache coherency is off/not present for device addesses), the driver needs to remap that memory as non-cacheable. Suppose there exists a chunk of physically-contiguous memory (say, memory reserved for device use) that happened to be already mapped... 21 Jul 2010 14:43
