Amazon Exploring MM-Local Memory Allocations To Help With Current/Future Speculation Attacks
Amazon Exploring MM-Local Memory Allocations To Help With Current/Future Speculation Attacks
23 June 09:42 AM EDT - Linux Security - MM-Local Memory Allocations - 3 Comments

Back in 2019 after various speculation-based CPU vulnerabilities began coming to light, Amazon engineers proposed process-local memory allocations for hiding KVM secrets. They were striving for an alternative mitigation for vulnerabilities like L1TF by essentially providing some memory regions for kernel allocations out of view/access from other kernel code. Amazon engineers this week laid out a new proposal after five years of ongoing Linux kernel improvements for MM-local memory allocations for dealing with current and future speculation-based cross-process attacks.

With some Linux users not liking the recently showcased new Linux "Blue Screen of Death" for kernel panics, Red Hat engineer Javier Martinez Canillas who has been one of those involved in the new DRM Panic infrastructure showed that it can also be a "black screen of death" if so desired.

Intel Lunar Lake Workload Hints & Power Floor Patches Posted For Linux
21 June 07:02 AM EDT - Intel - Intel Lunar Lake - Add A Comment

Intel software engineers have been upstreaming the Lunar Lake support for Linux a number of months already and the basics appear in good shape, aside from the Xe2 graphics enablement being an ongoing matter. Much of the rest of the core functionality has appeared to be in good shape ahead of Lunar Lake laptops launching in Q3, but it seems there have been a few missing power management related bits.

Qualcomm Cloud AI 100 "AIC100" Firmware Upstreamed
20 June 03:57 PM EDT - Hardware - Qualcomm AIC100 - 1 Comment

While not talked about as much as the likes of the Intel Gaudi accelerators with their upstream Habana Labs kernel driver or the AMD Instinct MI300 series with their open-source upstream support too, back in 2022 Qualcomm did post an open-source kernel driver for their Cloud AI accelerator. That was followed by an open-source compiler and user-space stack and in turn the QAIC driver was upstreamed into the accelerator (accel) subsystem last year with Linux 6.4.

Intel Linux NPU Driver v1.5 Released - Now Validated On Arrow Lake & Lunar Lake
20 June 01:15 PM EDT - Intel - Intel Linux NPU Driver 1.5 - 3 Comments

Intel on Wednesday released version 1.5 of their Linux NPU driver, their user-space driver component for Linux systems in enabling the neural processing unit found with Core Ultra "Meteor Lake" processors and newer. This goes along with their upstream IVPU kernel accelerator driver for allowing a full open-source solution for AI workloads with the likes of OpenVINO.

Raspberry Pi 5 Kernel Graphics Driver Support Will Hopefully Be Upstreamed Soon
20 June 12:36 PM EDT - Raspberry Pi - Raspberry Pi 5 Kernel Driver - 16 Comments

While the Raspberry Pi 5 debuted last September, the mainline Linux kernel support for this popular single board computer continues to lag behind the state of Raspberry Pi's downstream kernel. SUSE has been working to upstream various Raspberry Pi 5 driver support while now Raspberry Pi engineers have also begun the trek toward upstreaming their kernel graphics driver support.

Intel Introduces New Gaudi "2D" Product Support To Their Linux Driver
20 June 06:30 AM EDT - Intel - Gaudi2-D - 1 Comment

It was just a few months back that Intel introduced a Gaudi "2C" variant of Gaudi2 to their open-source Linux driver. This variant might be for some export model or otherwise a hyperscaler/customer-specific revision or something along those lines. Now appearing within new Habana Labs driver patches for the upcoming Linux 6.11 kernel are patches for a new Gaudi 2D variant.
