## QAT20-38022
| Title | CY – Edwards and Montgomery curves not supported in PKE operations |
|---------------|:-------------------------------------------------------------------|
| Reference # | QAT20-38022 |
| Description | On some platforms the function cpaCyQueryCapabilities() will report the ecEdMontSupported capability as FALSE and operations using those curves will fail. This case can arise when qatlib is running in a guest and the QAT kernel driver on the host is not a standard Linux in-tree kernel driver. For example, it can occur with some Linux out-of-tree, VMware® ESXi and Windows® QAT kernel drivers. |
| Implication | PKE operations using those elliptic curves will fail. |
| Resolution | There are three ways to resolve this: (a) If host OS is Linux, use the QAT driver which comes with any standard Linux kernel, i.e. the in-tree driver. (b) Apply [this patch](https://github.com/intel/qatlib/commit/e72bf1b27adafd58efbbf643a752a9ffdcfeb5a3) to your qatlib source code and rebuild and re-install the library. (c) Install an updated QAT kernel driver on the host, which reports a fix for this issue in its release notes. |
| Affected OS | Linux, VMware®, Windows® |
| Driver/Module | CPM-IA – Only applies to QAT GEN4 devices. |
