AMD and Intel (x86) in Linux

  • Linux 5.10 Adding Support For AMD Zen 3 CPU Temperature Monitoring

    The next version of the Linux kernel will allow monitoring temperatures of the upcoming AMD Zen 3 processors. While CPU temperature monitoring support may seem mundane and not newsworthy, what makes this Zen 3 support genuinely interesting is that it's coming pre-launch... This is the first time in the AMD Zen era we are seeing CPU temperature reporting added to the Linux driver pre-launch. Not only is it coming ahead of the CPUs hitting retail channels but the support was added by AMD engineers.

  • FFmpeg Now Supports GPU Inference With Intel's OpenVINO

  • Intel SGX Enclave Support Sent Out For Linux A 38th Time

    For years now Intel Linux developers have been working on getting their Software Guard Extensions (SGX) support and new SGX Enclave driver upstreamed into the kernel. SGX has been around since Skylake but security concerns and other technical reasons have held up this "SGX Foundations" support from being mainlined. There has also been an apparent lack of enthusiasm by non-Intel upstream kernel developers in SGX. This past week saw the 38th revision to the patches in their quest to upstreaming this support for handling the Memory Encryption Engine (MEE) and relates SGX infrastructure. [...] The Intel SGX foundations v38 code can be found via the kernel mailing list. The Linux 5.10 merge window is opening up next month but remains to be seen if it will be queued for this next cycle or further dragged out into 2021.

  • Intel SGX foundations
    Intel(R) SGX is a set of CPU instructions that can be used by applications
    to set aside private regions of code and data. The code outside the enclave
    is disallowed to access the memory inside the enclave by the CPU access
    There is a new hardware unit in the processor called Memory Encryption
    Engine (MEE) starting from the Skylake microacrhitecture. BIOS can define
    one or many MEE regions that can hold enclave data by configuring them with
    PRMRR registers.
    The MEE automatically encrypts the data leaving the processor package to
    the MEE regions. The data is encrypted using a random key whose life-time
    is exactly one power cycle.
    The current implementation requires that the firmware sets
    IA32_SGXLEPUBKEYHASH* MSRs as writable so that ultimately the kernel can
    decide what enclaves it wants run. The implementation does not create
    any bottlenecks to support read-only MSRs later on.
    You can tell if your CPU supports SGX by looking into /proc/cpuinfo:
    	cat /proc/cpuinfo  | grep sgx
