Greg KH Recommends Avoiding Alder Lake Laptops - Intel Webcam Linux Driver Long Ways Out
Greg KH Recommends Avoiding Alder Lake Laptops - Intel Webcam Linux Driver Long Ways Out

Greg Kroah-Hartman as the Linux kernel's stable maintainer and effectively Linus Torvalds' second-in-command has suggested avoiding Intel Alder Lake laptops. While much of the Alder Lake laptop support for Linux is in good shape, the exception is around web cameras. These newer laptops with Intel's latest web-camera tech are not currently supported by the mainline kernel and require proprietary software for use. Some platforms like Ubuntu and ChromeOS are picking up these blobs for now while a proper open-source, upstream solution is likely months -- or likely about one year -- away.

Intel Xeon Platinum 8380 Performance Is Looking Great For Linux 6.0

Not only is the AMD EPYC performance looking real good for Linux 6.0, but many of the scheduler changes and common kernel improvements also carry over well for Intel's Xeon Platinum 8380 "Ice Lake" server processors too. For your viewing pleasure this weekend are some initial benchmarks looking at Linux 5.19 stable compared to Linux 6.0 Git as we approach the end of the merge window.

Intel Preps HWMON Support For Linux Driver To Expose Power / Voltage / Energy Reporting
Intel Preps HWMON Support For Linux Driver To Expose Power / Voltage / Energy Reporting

While much of the Intel Arc Graphics "Alchemist" (DG2) support appears squared away for Linux 6.0 besides the support still being hidden behind the flag requiring i915.force_probe= to actually enable the experimental support, there still are various DG2 discrete GPU features being tackled by the open-source Intel kernel graphics drivers. One of those "extras" still working its way to the kernel is HWMON subsystem integration to be able to expose power / voltage / energy reporting.

Intel Firmware Engineers Make An Important Power Improvement For Sapphire Rapids
Intel Firmware Engineers Make An Important Power Improvement For Sapphire Rapids

Earlier this year I wrote about the Intel Idle driver support being prepared for Xeon "Sapphire Rapids" CPUs but a limitation with these forthcoming Xeon Scalable processors was that C1 and C1E c-states handling are now mutually exclusive. Unlike earlier Xeon processors, C1 and C1E states couldn't be enabled at the same time. Fortunately, via new Intel firmware they have managed to overcome this limitation.

Intel GSC Support Continues To Get Squared Away For DG2/Alchemist
Intel GSC Support Continues To Get Squared Away For DG2/Alchemist

While much of Intel's Arc Graphics DG2/Alchemist enablement appears to be in decent shape for Linux 5.20 with the small BAR support expected to land, the compute support being exposed to user-space in 5.19, etc, one of the few remaining pieces is the GSC support. The Intel GSC is their new Graphics System Controller found with their discrete GPU and used for security-related operations.

Intel GuC Firmware Fix Submitted For Linux 5.19

Sent in on Friday night were this week's batch of Direct Rendering Manager (DRM) driver fixes for Linux 5.19-rc8 due out on Sunday. While usually the late-stage changes tend to be not too eventful, this pull does carry some extra interest since it does fix the Intel GuC firmware breakage I wrote about last week that ended up breaking Alder Lake P graphics on Linux 5.19 unless also upgrading the firmware version.

Intel Working On New Hardware-Based Prevention For Spectre-BHI Attacks
Intel Working On New Hardware-Based Prevention For Spectre-BHI Attacks

While Retbleed was grabbing the headlines last week and attention of kernel developers, an Intel engineer sent out a new patch series adding Linux kernel support for "BHI_DIS" as a new hardware-based mitigation that appears to be coming with future Intel CPUs for better fending off Spectre-BHI (Branch History Injection) that was disclosed back in March. But initial indications are this new hardware-based prevention may be even more costly for performance and is not being enabled by default.

Oh GuC: Intel ADL-P Graphics On Linux 5.19 Will Break Unless You Also Upgrade Firmware
Oh GuC: Intel ADL-P Graphics On Linux 5.19 Will Break Unless You Also Upgrade Firmware

As a public service announcement for those who already have bought an Alder Lake P laptop or thinking of getting one, with kernel upgrades you need to be cautious/aware now of breaking accelerated graphics support due to versioned firmware requirements around the GuC micro-controller. While I am surprised Linus Torvalds allows this or wonder if he even is aware of it given his past statements on Linux kernel updates not breaking user-space, the Intel GuC firmware handling being versioned and not supporting backwards compatibility can throw a wrench into your upgrade experience like with the upcoming Linux 5.19 kernel.
