Read-copy update (RCU) ensures that any update carried out prior to the

beginning of an RCU grace period will be observed by the entirety of any
RCU reader that extends beyond the end of that grace period. Waiting for
grace periods is the purpose of the synchronize_rcu() function, which
waits for all pre-existing readers in a throughput-optimized manner

Outline the major pain points why Linux kernel regressions happen and why resolving some takes a long time as observed by Thorsten during three years of working as the kernel's regression tracker.
The talk among others will describe why some workflow patterns are what frequently leads to regressions -- and why they are also a factor why some subsystems fix regression quickly, while others...

Open-source software is increasingly reused, complicating the process of patching to repair bugs. In the case of Linux, a distinct ecosystem has formed, with Linux mainline serving as the upstream, stable or long-term-support (LTS) systems forked from mainline, and Linux distributions, such as Ubuntu and Android, as downstreams forked from stable or LTS systems for end-user use. Ideally, when...

Power fluctuations are a common challenge in embedded systems, where components like SD cards, eMMCs, and raw NAND flash are widely used for storage. These storage components are vulnerable to data corruption or even permanent damage when power unexpectedly drops. While larger systems, such as servers, often employ solutions like uninterruptible power supplies (UPS) to mitigate this risk, the...

In the context of starting the Nova driver project [1] it was decided to upstream Nova bit by bit and start with only a "stub" driver, in order to break the chicken-egg problem of Rust drivers requiring C API abstractions while upstreaming C API abstractions require at least one user.
As the one driving this project and this first effort, this talk is about sharing my experience from the...

There is a class of physical devices that contain several discrete modules in a single package but which are represented in the kernel as separate entities. An example of such devices is the Qualcomm WCN/QCA family of WLAN/Bluetooth adapter chipsets.
Typically the WLAN and Bluetooth modules will have their own device-tree nodes - one under the PCI bridge (WLAN) and one under the serial node...

The Linux Fundation Techical Advisory Board (TAB) exists to provide advice from the kernel community to the Linux Foundation and holds a seat on the LF's board of directors; it also serves to facilitate interactions both within the community and with outside entities. Over the last year, the TAB has overseen the organization of the
