我有一块技嘉 b365m 主板，配有最新的 BIOS F3a 和酷睿 i5-9600k。我已在 BIOS 中将英特尔 sgx 设置为“已启用”，但在 ubuntu 中，isgx 驱动程序intel_sgx: CPU does not support SGX1 instructions在dmesg输出中一直显示。我使用英特尔的 sgx 软件启用应用程序https://github.com/intel/sgx-software-enable获取 SGX 的状态。虽然它说
Intel SGX is explicitly disabled, and your BIOS does not
support the "software enable" option. Check your BIOS for an
explicit option to enable Intel SGX.
这太奇怪了！然后我在 bios 中将 SGX 设置为“软件控制”，在操作系统中，isgx 驱动程序显示
intel_sgx: SGX is not enabled。我使用 SGX 软件启用应用程序来启用 SGX，它显示成功。但是当我重新启动计算机并进入操作系统时，奇怪的事情再次发生：isgx 显示intel_sgx: CPU does not support SGX1 instructions。但 SGX 启用应用程序的输出变为：
The software enable has been performed on this system and
Intel SGX will be enabled after the system is rebooted.
然后我再次重新启动，但事情并没有改变。isgx 驱动程序仍然说：
intel_sgx: CPU does not support SGX1 instructions
SGX 应用程序的输出仍然是
The software enable has been performed on this system and
Intel SGX will be enabled after the system is rebooted.
为什么事情会发展到这个地步？https://ark.intel.com/content/www/us/en/ark.html很明显9600k支持SGX。这可能是ubuntu和bios不兼容的问题吗？输出cpuid|grep SGX：
