It is possible for\none of those regions to be above the dma mask of a device. It is typical\nto allocate iovas with a 32bit mask (despite device\u0027s dma mask possibly\nbeing larger) and cache the result until it exhausts the lower 32bit\naddress space. Freeing the iova range that is \u003e\u003d the last iova in the\nlower 32bit range when there is still an iova above the 32bit range will\ncorrupt the cached iova by pointing it to a region that is above 32bit.\nIf that region is also larger than the device\u0027s dma mask, a subsequent\nallocation will return an unusable iova and cause dma failure.\n\nSimply don\u0027t cache an iova that is above the 32bit caching boundary.\n\nReported-by: Mike Travis \u003ctravis@sgi.com\u003e\nReported-by: Mike Habeck \u003chabeck@sgi.com\u003e\nCc: stable@kernel.org\nAcked-by: Mike Travis \u003ctravis@sgi.com\u003e\nTested-by: Mike Habeck \u003chabeck@sgi.com\u003e\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\n" }, { "commit": "cb452a4040bb051d92e85d6e7eb60c11734c1781", "tree": "ef19298ec70274c9c199fa74a4f08e77cc69080b", "parents": [ "8fcc5372fbac085199d84a880503ed67aba3fe49" ], "author": { "name": "Mike Travis", "email": "travis@sgi.com", "time": "Sat May 28 13:15:03 2011 -0500" }, "committer": { "name": "David Woodhouse", "email": "David.Woodhouse@intel.com", "time": "Wed Jun 01 12:47:36 2011 +0100" }, "message": "intel-iommu: Speed up processing of the identity_mapping function\n\nWhen there are a large count of PCI devices, and the pass through\noption for iommu is set, much time is spent in the identity_mapping\nfunction hunting though the iommu domains to check if a specific\ndevice is \"identity mapped\".\n\nSpeed up the function by checking the cached info to see if\nit\u0027s mapped to the static identity domain.\n\nSigned-off-by: Mike Travis \u003ctravis@sgi.com\u003e\nReviewed-by: Mike Habeck \u003chabeck@sgi.com\u003e\nCc: stable@kernel.org\nSigned-off-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\n" }, { "commit": "8fcc5372fbac085199d84a880503ed67aba3fe49", "tree": "aab84e5ac18fa8028efa49e2cc47a5b97d873916", "parents": [ "9b4554b21ed07e8556405510638171f0c787742a" ], "author": { "name": "Chris Wright", "email": "chrisw@sous-sol.org", "time": "Sat May 28 13:15:02 2011 -0500" }, "committer": { "name": "David Woodhouse", "email": "David.Woodhouse@intel.com", "time": "Wed Jun 01 12:47:34 2011 +0100" }, "message": "intel-iommu: Check for identity mapping candidate using system dma mask\n\nThe identity mapping code appears to make the assumption that if the\ndevices dma_mask is greater than 32bits the device can use identity\nmapping.

That arguably means we shouldn\u0027t be using\nMSI or extended config space, but right now our problems seem to be limited\nto vendors being surprised when ASPM gets enabled on machines when other\nOSs refuse to do so. So, for now, let\u0027s just disable ASPM if the _OSC\nmethod doesn\u0027t exist or refuses to hand over PCIe capability control.]\n\nSigned-off-by: Naga Chumbalkar \u003cnagananda.chumbalkar@hp.com\u003e\nCc: Rafael J.
