-<p>Triple-booting two versions of macOS and Asahi Linux with the built-in boot picker</p></figcaption></figure><h2 id=more-kernel-drivers>More kernel drivers</h2><p>Sven has been dutifully working on the Linux driver for <a href=/docs/Glossary#d>DART</a>, the M1’s IOMMU (I/O Memory Management Unit). This driver is required to make all kinds of hardware work, like PCIe, USB, DCP, and more. It has just been accepted by upstream and is now on its way to Linux 5.15!</p><p>With this driver in, we can now make USB and PCIe work with minimal additional patches and drivers. There are various other dependencies (GPIO for miscellaneous things, I²C for proper USB-PD support, SPI for touchpad/keyboard support on the laptops, and NVMe support patches) that are spread around in various trees that people have been working on. Next we’ll direct our focus towards polishing these simpler drivers and putting together a clean, working reference tree that we can use to continue development and provide new developers with a stable foundation. With the current state of things, it’s already possible to use Asahi Linux as a development machine with a (non-accelerated) GUI, although things are still rough around the edges. Upstreaming these changes will require a bit more time, as there are some bureaucratic yaks to be shaved around how to properly implement these (technically simple) drivers, but things shouldn’t take too long!</p><p>And once that’s on the way… it’s time to tackle the GPU kernel driver! Things are about to get exciting :-)</p><div class=post-bottom>marcan · <span class=publishdate>2021-08-14</span></div></div></div></section><script>document.addEventListener("DOMContentLoaded",function(){document.referrer.match("//news.ycombinator.com")&&(document.body.ariaHidden=!0,document.body.innerHTML="<style>.hnsucks { background-color: #ff6600; padding: 20px; color: #000;}.hnsucks p { margin-bottom: 20px; font-family: Verdana, Geneva, sans-serif; font-weight: revert; max-width: 60em; margin-left: auto; margin-right: auto; font-size: 1.25em;}.hnsucks a { text-decoration: underline;}</style><div class='hnsucks'><p>Hi! It looks like you might have come from Hacker News.</p><p>Asahi Linux developers are frequent targets of abuse on Hacker News.

Unfortunately, when a comment is flagged and killed, its child subthread is not. That preserves the 'clean' image of the website, but the reduced moderation activity enables abuse to continue.

HN uniquely has a high page rank and low moderation, making it a prime target for <a href='https://en.wikipedia.org/wiki/Kiwi_Farms'>bad actors</a> to poison search results with abuse, bigotry, and nastiness.
