Back in January "iGPU Leak" was disclosed as CVE-2019-14615 as an information leakage vulnerability affecting Intel's graphics architecture leading to both register and local memory leaks. While Intel "Gen9" graphics were patched right away on the disclosure date and Gen8 Broadwell graphics were already mitigated, Gen7/Gen7.5 graphics took longer... In fact, not until the Linux 5.7 release this spring is there the mitigation for iGPU Leak...

It's been a while since having news on Redox OS as the Rustlang-written open-source operating system. But it turns out that's been due to Jeremy Soller being busy working on Pkgar as a new package management format for the operating system...

Over the past year we have seen a steady flow of Intel Tiger Lake "Gen12" graphics enablement for the Linux kernel, their first generation also adopting the Xe Graphics branding as part of their discrete GPU initiative. With the Linux 5.7 kernel this spring will be the first release where the Gen12 graphics support is there by default as a sign of stability...

Any regular Phoronix reader should already be quite familiar with SVT-AV1 and the other open-source Scalable Video Technology encoders considering how much we have been benchmarking them -- months before even before they were officially announced. Netflix, which has been working on SVT-AV1 in conjunction with Intel, has an interesting write-up for some weekend reading on the state of this open-source AV1 encoder/decoder...

Currently the Linux kernel SECCOMP secure computing mode force-enables Spectre protections, which comes with obvious performance implications. When force-enabled, however, processes can't opt-out of the protection if they are not at risk to the likes of Spectre V4 "Speculative Store Bypass" issues. But a simple change being proposed would let such processes opt out if desired...

One of the most frequent critiques of Intel's Clear Linux distribution has been its lackluster support in dealing with proprietary/third-party packages like the Google Chrome web browser and Valve's Steam gaming client. Since last summer, Clear Linux has been working on their third-party packaging support with their unique "bundles" system, but not much has been heard on the matter since...

Feature work of Direct Rendering Manager (DRM) graphics driver work for Linux 5.7 is winding down now that Linux 5.6 is almost to its sixth release candidate this weekend, but sent in this week by AMD were a few more AMDGPU items though mostly amounting to fixes for their graphics driver...

In addition to WebAssembly's growing presence outside of the web browser thanks to various desktop run-times and interesting use-cases, WebAssembly is also popping up in other areas. Google has been working on WebAssembly support for extensions within network proxies typically reserved for C/C++ or the likes of Lua scripts...

On Tuesday the Load Value Injection (LVI) attack was disclosed by Intel and security researchers as a new class of transient-execution attacks and could lead to injecting data into a victim program and in turn stealing data, including from within SGX enclaves. While Intel has publicly stated they don't believe the LVI attack to be practical, one of their open-source compiler wizards did go ahead and add mitigation options to the GNU Assembler as part of the GCC toolchain. Here are benchmarks showing the performance impact of enabling those new LVI mitigation options and the significant impact they can cause on run-time performance in real-world workloads.

We've known that Intel's P-State Linux CPU frequency scaling driver in general can be a bit quirky and especially so when dealing with Intel integrated graphics where the iGPU and CPU share the same power envelope. This has been shown with examples like using the "powersave" governor to boost iGPU performance while discrete graphics owners are generally best off switching over to the "performance" governor. As the latest though on helping the iGPU front with P-State, there is a new patch series talking up big gains in performance and power efficiency...

Load Value Injection (LVI) is being disclosed today as a new class of transient-execution attacks and the researchers claim can defeat all existing mitigations around Meltdown, Foreshadow, Zombieload, RIDL and Fallout. The researchers say LVI can affect virtually any access to memory and compiler-based mitigations can be expensive...

With the Linux 5.7 kernel this spring there is going to be a new exFAT file-system drive developed by Samsung as outlined last week. While that is being added to the formal file-system area of the kernel rather than staging so both could co-exist for a transition period, already with Linux 5.7 will be the removal of the existing staging driver...
