Thank you for your reply! My pc has the PASID capability, See the attachment.
ok. BTW. A heads up: you are looping the mailing list, so you'd better use the plain text format and avoid including pictures if it can be expressed by text.
" I don't think the AMD iommu driver has supported the set_dev_pasid callback for the non-SVA domains." ------ xuemei : So if I want to use the PASID to test PCIE ATS request messages,could you give some suggestions ? usr SVA domain can solve thie issue ?
You should not mix ATS with PASID, ATS does not rely on PASID. You should be able to test ATS without PASID. ATS is a performance feature, so if you want to test it in system level, you need a benchmark to do it. Or you can test it in pci transaction level, you would need tools for it then. It's up to you. -- Regards, Yi Liu
