Kernel: KVM Protected Memory Extension and MediaTek

Intel Engineer Proposes Software-Based KVM Protected Memory Extension
While modern AMD EPYC CPUs support Secure Encrypted Virtualization (SEV) and Intel more recently has been working on MKTME for similarly offering hardware-backed total memory encryption, an Intel open-source engineer has now proposed a software-based solution for protected memory support for KVM virtualization.
The proposed KVM protected memory extension is a software-based solution for protecting guest memory from unauthorized host access, at least in partial form. This prevents the host kernel from accidentally leaking guest data, host user-space access to guest data, and similar solutions. But unlike Intel MKTME and AMD SEV, this does not provide full protection against the host kernel being compromised or hardware-based attacks.

Many MediaTek Wireless Driver Improvements On Deck For Linux 5.8
There is a lot of wireless (and wired) networking activity each kernel cycle but for the upcoming Linux 5.8 merge window it looks like there will be particularly a lot for MediaTek drivers.
The MediaTek MT76 driver work now queued in wireless-drivers-next ahead of Linux 5.8 has around 14 thousand lines of new code. Among the MediaTek wireless highlights are:
- New device support for MediaTek MT76x0 and MT76x2 hardware.
- MT7615 and MT7663 fixes.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
