After fighting with the divide between implicit and explicit synchronization with Vulkan on Linux for over seven years, we may finally have some closure. We're not to synchronization nirvana quite yet, but this is an important step along the way.

Optical hand tracking for XR has a bit of a reputation - getting training data, training neural nets, and deploying them in real-time, low-latency environments such as XR is every bit as hard as they say it is.

Monado now has initial support for 6DoF ("inside-out") tracking for devices with cameras and an IMU! Three free and open source SLAM/VIO solutions were integrated and adapted to work on XR: Kimera-VIO, ORB-SLAM3, and Basalt.

When developing an application or a library, it is very common to want to run it without installing it, or to install it into a custom prefix rather than on the system. Here's how Meson can help with that.

An incredible amount has changed in Mesa and in the Vulkan ecosystems since we wrote the first Vulkan driver in Mesa for Intel hardware back in 2015. Not only has Vulkan grown, but Mesa has as well.

Every file system used in production has tools to try to recover from system crashes. To provide a better infrastructure for those tools, our kernel team developed FAN_FS_ERROR, a new fanotify event which monitors error notifications.

Over the past 18 months, we have been on a roller-coaster ride developing futex2, a new set of system calls. As part of this effort, the futex_waitv() syscall has now landed in Linux 5.16. But what exactly is futex?

Until now, no Valhall devices (Mali-G57, Mali-G78) ran mainline Linux - whilst this made driver development obviously difficult, there’s no better time to write drivers than before the devices even get into the hands of end users.

My work on Wayland and Weston color management and HDR support has been full of learning new concepts and terms. Many of them are crucial for understanding how color works, and what the values in a pixel actually mean.

It has been just over a year since we first announced our effort to implement a Wayland driver for Wine. Here's a recap of what has been done since then to improve both the functionality and stability of the driver.
