Is the Arm CXL support still out-of-tree? I ask because at the moment docs/system/devices/cxl.rst has some aarch64 virt command lines which don't work, and we've had a bug report about it: https://gitlab.com/qemu-project/qemu/-/issues/1892 Could you submit a patch to correct the documentation, please (either fixing the command line, or just deleting any claims to aarch64 support if it's not upstream) ? thanks -- PMM
