jsheard: I haven't listened to this podcast yet so I don't know if this comes up, but a particularly scary part of running a custom OS on Apple Silicon machines is that the internal speakers temperature is regulated in software. The Asahi devs have had to painstakingly reverse engineer and reimplement the safety DSP that macOS uses on each device, and add some safety margin, because if they get it wrong they could literally destroy the speakers (and IIRC at least one of their own MacBooks did have its speakers sacrificed along the way).<p>I wonder if there will be a similar issue with the displays when Asahi gets around to supporting HDR on machines equipped with FALD mini-LED backlights (or XDR, as Apple calls it). HDR displays usually regulate their brightness to keep the panel from getting too hot, and if Apple does that in software too then Asahi will need to replicate it.
jsheard: 我还没有;我还没有听这个播客,所以我没有;我不知道是否会出现这种情况,但在Apple Silicon机器上运行自定义操作系统的一个特别可怕的部分是,内部扬声器的温度是由软件调节的。朝日开发人员不得不煞费苦心地对macOS在每台设备上使用的安全DSP进行逆向工程和重新实现,并增加一些安全裕度,因为如果他们弄错了,他们可能会破坏扬声器(IIRC至少有一台自己的MacBook在这一过程中牺牲了扬声器)<p> 我想知道,当朝日在配备FALD迷你LED背光(或苹果公司称之为XDR)的机器上支持HDR时,显示器是否会出现类似的问题。HDR显示器通常会调节亮度,以防止面板过热,如果苹果也在软件中这样做,那么朝日将需要复制它。
unit149: Reverse engineering the first bit of Apple's flagship M1 CPU, which was implemented in the original iPhone released back in '08, through an ARM-based architectural analysis, and integrating it into Linux kernel system calls is an extreme measure. This reduplication of the original dump, checking its hex value, then altering it to see if the application is functional. Doing x,y, and z, then seeing if it works inside VM hypervisor-space.<p><a href="https://softwareengineeringdaily.com/wp-content/uploads/2024/10/SED1754-Asahi-Linux.txt" rel="nofollow">https://softwareengineeringdaily.com/wp-content/uploads/2024...</a>
unit149: 对Apple的第一部分进行逆向工程;其旗舰产品M1 CPU在年月发布的原始iPhone中实现;08,通过基于ARM的架构分析,并将其集成到Linux内核系统调用中是一种极端的措施。重复原始转储,检查其十六进制值,然后更改它以查看应用程序是否正常工作。执行x、y和z,然后查看它是否在VM管理程序空间内工作<p> <a href=“https:/;softwareengineeringdaly.com&#wp-content/上传� SED1754 Asahi Linux.txt”rel=“nofollow”>https:/;softwareengineeringdaly.com;wp内容;上传;2024年</a>
chubs: What would be possible if everyone interested in Linux-on-macOS chipped in $5 each month? I wonder if this could fund a big enough team to make this super-polished.
chubs: 如果每个对macOS上的Linux感兴趣的人每月都能赚到5美元,那会有什么可能?我想知道这是否可以资助一个足够大的团队来制作这个超级精美的作品。
AI_beffr: its insane to me that people are working so hard on reverse engineering apple silicon. like, the diagrams are right there in cupertino. it just seems like such a waste. its like during some kind of economic depression there are people starving and struggling while a bunch of food and resources are just sitting around not being used. existential grid-lock.
AI_beffr: 在我看来,人们如此努力地对苹果硅进行逆向工程,这太疯狂了。就像,图表就在库比蒂诺。这看起来真是浪费。这就像在某种经济萧条时期,人们挨饿挣扎,而一堆食物和资源却闲置着,没有得到利用。存在网格锁。
SG-: the negative comments in this thread are frankly disappointing especially for a place called "hacker news". like Linux doesn't have roots in reverse engineering and continued reverse engineering and people here constantly "advocating" for open source drivers from likes of Nvidia instead of the close source binary blobs.<p>yet here someone makes great effort and most comments are negative Nancy's asking why it's being done or bringing up support issues with newer hardware revisions from a 1-3 person outfit that everyone said would be impossible to do.
SG-: 坦率地说,这条帖子中的负面评论令人失望,尤其是对于一个名为";黑客新闻”;。就像Linux一样;没有逆向工程的根基,也没有持续的逆向工程,这里的人不断";倡导";用于Nvidia等开源驱动程序,而不是闭源二进制blob<p> 然而,这里有人付出了巨大的努力,大多数评论都是负面的;她问为什么;一个1-3人的团队正在完成或提出新硬件版本的支持问题,每个人都说这是不可能的。
