OP-TEE 3.5.0 was released when I worked on this version of the pathes. This is the first release where virtualization support is available. This release includes both original virtualization patches and new SMC that retrevies number of threads from OP-TEE. Many thanks to both OP-TEE and Xen communities for reviewing and helping with my changes to the both projects. Global changes from v4: - Substantial rework of OP-TEE mediator. Now it tries to return meaningful error codes back to the guest. - OP-TEE mediator does not use struct cpu_user_regs as a storage for parameters and return values when calling OP-TEE. This makes it compatbile with requirement from SMCCC. - tee=native option replaced with tee=optee - Authorship and s-o-b tag reset to my EPAM mail address Overall changes from v3: - Patch "arm: add tee_enabled flag to xen_arch_domainconfig" was squashed into "xen/arm: add generic TEE mediator framework" - I implemented more elaborate error repoting to a guest. Now guest will get meaningful error codes instead of generic ARM_SMCCC_ERR_UNKNOWN_FUNCTION. Per-patch changes are described in corresponding emails. Changes from v2: - Use domain flags insted of domctl interface to enable optee for guests - Remove patch "libxc: add xc_dom_tee_enable(...) function" because of previous change - Mediator now stores own context in arch part of struct domain, so I removed patch "optee: add domain contexts" Per-patch changes are described in corresponding emails. ==== v2: This is v2 of patch series for OP-TEE mediator support in XEN. Changes from v1: - Added domctl interface, so now xl decides what domain should work with TEE - Removed XSM support due to change described above - Patch with OP-TEE mediator was splited to 7 separate patches - Removed patch with call_smccc() function. Now this series depend on Julien Grall's series "xen/arm: SMCCC fixup and improvement" [3] ===== v1: This is follow for patch series [1]. There was lots of discussions for that series and I tried to address all of them in this new patchset. Currently, I had a working solution for OP-TEE virtualization and it is being upstreamed right now ([2]). So, I think it is a good time to introduce support in XEN as well. This series include generic TEE mediator framework and full-scale OP-TEE mediator which is working with mentioned chages in OP-TEE. So, multiple domains can work simultaneously with OP-TEE. I added XSM support, so now it is possible to control which domains can work with TEEs. Also I changed way how TEE discovery is done. Now it is very generic and should support any platform.
