Running Mainline Linux on Snapdragon 410

How we support over 25 devices in postmarketOS

<p>The Qualcomm Snapdragon 410 (msm8916) is a SoC that was used in many smartphones and tablets around 2015. It is the most mature "aftermarket" platform postmarketOS can offer at the time of writing. Many of the supported devices are quite usable and have most of the expected features like phone calls and mobile data working.</p> <p>The talk goes over some of the most important challenges that we have faced while supporting those devices and describes the ways in which we have solved them.</p>
Apart from the Linux kernel, we focus on various other tools and projects like lk2nd - a shim bootloader that prepares the environment for booting Linux and hides some device-specific quirks from the kernel. It also unifies the boot and installation process on all devices. We also have other tools and resources to make porting easier. Those include various documentation or even a fully automated display driver generator that helps with the fact that each display requires unique initialization.

<p>The reMarkable 2 is an eInk tablet, based on the i.MX7 SoC. The tablet ships with a fork of the 4.14 kernel and a custom rootFS built with OpenEmbedded. The vendor kernel is based on the NXP vendor kernel with a large collection of rM2 specific patches on top.</p> <p>This talk discusses the process of adding support for the rM2 to the mainline Linux kernel. The talk first discusses the process of understanding the original boot process and then getting access to a download mechanism and ...

<p>I work with Purism SPC on the Librem 5 phone kernel. I regularly post what our team pushes upstream into the mainline kernel at https://puri.sm/posts/author/martin/</p> <p>In this little talk I want to summarize what we've done, describe how we do it and put it into perspective a bit.</p> <p>I'll outline rough future plans and of course encourage to participate in case you own that phone.</p>

<p>OpenMandriva and its predecessors have been in the desktop and server world since the 1990s - now OpenMandriva 4.3 can run on the PinePhone. What did we have to do to get there and what problems have to be solved before it can fully replace that Android phone in my pocket?</p>

<p>The Mobian project was initiated a few days prior to FOSDEM'20, back when the first PinePhones (BraveHeart edition) were arriving in the hands of developers and enthusiasts. From a single-person weekend project aimed at running Debian on one specific device, to one of the major mobile Linux distributions, let's board into a journey through the past, present and future of Mobian!</p>

<p>Most Kobo/Tolino readers offer a well marked console port and often a second UART. If they are not water resistant, they offer an internal µSD card slot containing the whole operating system and bootloader so that sounds like an invitation to do something interesting with them besides just reading books. Especially in prolonged outdoor activities, the display and their low power consumption have their merits. Hardware is quite similar, so you also have chances to get a replacement next ...
