Haiku Archive

Have you ever want to follow along as someone ports an entire operating system to a new architecture? Well, now you can! Haiku developer X512 is porting the Haiku operating system to RISC-V, and is posting regularly in a long and detailed ongoing thread on the Haiku discussion forum, detailing his successes and struggles along the way. He’s already quite far along: Most things are working, system is quite stable. Now applications crash show error dialog instead of KDL. Also after removing no more needed workarounds (fully allocate stack memory instead of allocating on demand by page fault handler) memory usage was reduced. It’s fun and informative to read the whole thread from the beginning until today, and see the progress unfold as if you’re sitting right next to X512.

When I first got my 133MHz BeBox (not new, sadly), it had “only” 32MB of memory and it had four more SIMM slots to fill. While Be only officially supported 256MB of RAM, I was blissfully ignorant of that, bought an additional 256MB of memory in four equally sized 72-pin SIMMs and installed it for 288MB of RAM. (It can actually take up to 1GB, I later learned.) Nice, I said! And then SheepShaver never worked again. This is basically OSNews catnip.

Another month, another Haiku activity report. January was a busy month for OSNews’ favourite operating system project, with a lot of love sent the way of the various ports to other architectures. Work has been done on the ARM and RISC-V ports, but also on platforms you might not expect in this day and age: SPARC and PowerPC. While some may question putting any effort into these alternative platforms at all, that’s a shortsighted position – work on other platforms often aides in uncovering and fixing bugs in the code for your main platform. It also prevents code from becoming more platform-dependent than it needs to be. Amid the long list of other improvements, the one that stands out is merging support for SD/MMC cards. The SD/MMC drivers are merged. It is now possible to read and write SD and SDHC cards using controllers compatible with the SDHCI specification. This is one of those things that will make it easier to transfer files to and from your Haiku installation.

A number of patches worked on for Haiku OS back for Mesa 20.x were freshened up and with some extra tweaking and code cleaning those patches have now been merged for Mesa 21.0. This includes factoring out a lot of the OpenGL legacy dispatch code and a lot of cleanups around the Softpipe driver handling. With Mesa 21.0-devel as of today, it’s at least enough where Mesa Git can now be built on Haiku OS and yield working OpenGL rendering with the LLVMpipe software. Neat, and a testament to Haiku being in a far better state than many people seem to think.

For a long time I have been maintaining the build of the Rust compiler and development tools on Haiku. For this purpose, I maintain a separate tree with the Rust source, with some patches and specific build instructions. My ultimate end goal is to have Rust build on Haiku from the original source, without any specific patches or workarounds. Instead we are in the situation where we cannot build rust on Haiku itself (instead we need to cross-compile it), and we need a customization to be able to run the Rust compiler (rustc) and package manager (cargo) on Haiku. This summer my goal would be to find out the underlying issue, and fix it so that the patch will no longer be necessary in the future. Let’s go! There seems to be quite a bit of excitement around the Rust programming language, so it makes sense for Haiku to jump on the bandwagon as well.

The July activity report from the Haiku project is out, and there’s a lot of stuff in there. My favourite highlight: kallisti5 continued work on the ARM architecture, specifically the ARM64 EFI bootloader. EFI CPU code was refactored to be architecture-specific, allowing CPU init code to be properly called, further progressing the EFI bootloader, which is now building and running. I love the progress on ARM, since ARM seems to have a bright future – Haiku needs to be there.

Did you ever wonder what BeIA really was? A lot of people talked about BeIA back in the days Be, Inc. was still developing its OS for internet appliances, but after Be, Inc. closed its doors, BeIA vanished as well. A thread over on the Haiku discussion forums – which began as a talking point for how Haiku could recreate a BeIA style concept – turned in to a treasure trove of BeIA information, including examples of BeIA running and an overview of some of the process of building BeIA distributions. This video shows it all in action, including BeIA running under emulation. There’s also a wonderful video shot in Be, Inc’s offices where a Hungarian UG member gets a tour and shown BeIA hardware, with terrible framerate and resolution, but well worth checking out.

After the release of the second beta a few weeks ago, Haiku continues its steady pace of improvements and fixes. A few highlights from the work done since the beta release: Korli also worked on improving support for modern x86 CPUs, including the xsave instruction, and enabling use of AVX which requires saving more CPU registers during context switches. A new version of HaikuWebKit has finally been released after help from KapiX and X512 to fix the remaining bugs. It uses a lot less memory, crashes less often, and has better support for modern website. There is ongoing work for further updates and improvements. There’s a lot more in there, so if you have beta 2 running, be sure to update it.

The big news first: a timeline has been set for Beta 2! If all goes well, it will be released by the end of May. Of course, this means everyone has been scrambling for last minute changes this month instead of stabilizing everything. We are now in “soft freeze”, and the branch will be created on Friday. Yes, an actual almost release date for Haiku’s second beta release.

You’re likely familiar with the old tale about how Steve Jobs was ousted from Apple and started his own company, NeXT. Apple then bought NeXT and their technologies and brought Jobs back as CEO once again. However, Jobs’ path wasn’t unique, and the history of computing since then could’ve gone a whole lot different. In 1990, Jean-Louis Gassée, who replaced Jobs in Apple as the head of Macintosh development, was also fired from the company. He then also formed his own computer company with the help of another ex-Apple employee, Steve Sakoman. They called it Be Inc, and their goal was to create a more modern operating system from scratch based on the object-oriented design of C++, using proprietary hardware that could allow for greater media capabilities unseen in personal computers at the time. Not much new information in here for the regular OSNews reader – and these articles get published about once a year – but it’s always nice to see the best operating system of all time get some love.

Another month two months have passed, so time for another monthly Haiku update. The biggest improvement this time around: PulkoMandy revisited once again the intel_extreme driver to identify the remaining regressions introduced when adding sandy Bridge support. We believe all problems have been identified and solved, so, if you have an intel graphics card, please test a recent nightly and report on what happens. There’s also a ton of non-x86 commits this time around.

Another month, another Haiku activity report – this time for September. It’s another big one, but if I had to pick one thing to highlight, it’d be this one: Some initial work for ARM64 was completed by kallisti5. This includes setting up the Haikuports package declarations, writing the early boot files, and in general getting the buildsystem going. Jaroslaw Pelczar also contributed several further patches (some of these still undergoing review), providing the initial interrupt handling support, and various stubs to let things compile kallisti5 did some work on 32bit ARM as well, cleaning up some of the code to better match other platforms and preparing the reuse of EFI for ARM and ARM64 (as u-boot now implements an EFI interface, which would make things much simpler for our ARM boot process if we manage to use it). Haiku has been working on ARM support for a while now, and while it may seem like a weird niche distraction for such a small project, it actually makes good, future-proofing sense to spend work hours in this area. ARM is definitely growing in the laptop space, and it makes sense to prepare Haiku for a future wherein ARM laptops are readily available. On top of that, adding support for architectures other than your main one aides in finding difficult to spot bugs, ensures architecture-independent code, and in general is just a fun thing to do for a specific kind of person.

Now that Haiku has entered the beta phase, and after the work over the past year or so spent fixing the majority of known kernel crashes and other general instabilities, it is high time we start paying more attention to the whole system’s performance. Despite how “snappy” Haiku seems, most of its internals are really not so well optimized. This shows when running operations of any real intensity (disk, memory, or CPU.) While the new thread scheduler a few years ago removed some of the thread-related bottlenecks, in practice this just shifted the load to other bottlenecks. So, let’s take an overview of this past month’s (and some earlier month’s) changes, to see how one optimizes an operating system. Haiku always feels very fast and snappy, but in reality, many of us have that perception because we tend to not really use Haiku as much as we use Windows or Linux. I’m really glad the Haiku team acknowledges this, and is looking to address low-level performance issues that may not look sexy in a changelog, but that are oh so crucial for the overall feel of the operating system.

Speaking of Travis Geiselbrecht – Haiku has another activity report. He also started benchmarking the uses of the allocator and found various opportunities to save memory, and use dedicated object caches instead of the generic malloc allocator, helping reduce memory fragmentation. The first patches have just started to land (in packagefs), there will likely be more. Ideally beta2 will be able to boot and install with 256MB of RAM or maybe even less thanks to this work. That’s the kind of specifications that make me very happy. It’s good to know that Haiku’s developers are attempting to keep the operating system lightweight enough to work on older hardware. Meanwhile, waddlesplash is also auditing the code and starting to work towards making APIs more restricted (allowing some things only for the root user, for example), in order to provide some more privilege separation. Haiku has so far been largely a single user system, and did not worry too much about the usual attack vectors for an UNIX system. But modern computers are often online and we should try to keep our user’s data reasonably safe. We have a long way to go, but we have to start with something. Multiuser will be one of the many big hurdles Haiku will face.
