When switching to 6.8-rc1, this commit was introduced: cb8eb06d50fcf4 x86/virt/tdx: Disable TDX host support when kexec is enabled
Which led to this config to be removed with this commit: ca03be74737277 UBUNTU: [Config] updateconfigs following v6.8-rc1 rebase So this isn't fixed in 6.8 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2046040 Title: enable CONFIG_INTEL_TDX_HOST in linux >= 6.7 for noble Status in linux package in Ubuntu: Fix Released Status in linux source package in Noble: Fix Released Bug description: [Impact] Intel Trust Domain Extensions (TDX) protects guest VMs from malicious host and certain physical attacks. Linux 6.7 introduced the TDX support for the host to run confidential VMs (TDX guests). [Test case] We should probably define with Intel a proper test case to test this feature, since it requires special hardware/firmware support. [Fix] Enable CONFIG_INTEL_TDX_HOST in our generic kernel. [Regression potential] The TDX host support may introduce potential performance regressions, so we should probably do some performance evaluation with vs without CONFIG_INTEL_TDX_HOST enabled.
