Developing Linux for Android on Qemu allows you to do some things that are not necessarily possible using the stock emulator. For my purposes I need access to a GPU and be able to modify the driver, which is where Virgilrenderer and Qemu comes in handy.

Nowadays, in Google Cloud Engine (GCE), it is possible to attach a local SSD with the NVMe interface to your virtual machine. Unfortunately, you only get a good number of iops (input/output operations per second) if you instantiate a machine with nvme-backports-debian-7-wheezy…

For years the open source Linux OpenGL drivers have been playing catchup to the proprietary drivers and in the case of Intel hardware to the Windows driver. Recently, a major milestone was reached in bridging this gap with the enablement of OpenGL 4.4…

For a long time I believed that echo cancellers had no place inside GStreamer. The theory was that GStreamer was too high level and would never be able to provide accurate enough delay information for any canceller to work.

Up until now, talking in-depth about userspace tracing was deliberately avoided because it merits special treatment, hence this part devoted to it. We'll now look at the why of it, and we'll examine eBPF user tracing in two categories: static and dynamic.

GStreamer's logging system is an incredibly powerful ally when debugging but it can sometimes be a bit daunting to dig through the massive amount of generated logs. I often find myself writing small scripts processing gst logs when debugging.

The second part of this series takes a more in-depth look at the eBPF VM and program studied in the first part. Having this low level knowledge is not mandatory but can be a very useful foundation for the rest of the series.
