Hello everyone!
Here’s the update for week 14 of work on the Haiku ARM port. I was travelling for a good part of week 13 and thus couldn’t get much work done during the time.
TL;DR - The problems of kernel overwriting the loader code and the exceptions when setting up framebuffer have been temporarily solved. The framebuffer related code has been disabled for now and the entire memory map moved to a higher address(when FDT support is implemented, a lot of these problems probably won’t arise). Currently, a fault is raised when the kernel attempts to obtain the same lock twice, which drops to KDL.
Hello there,
As mentioned in the previous report, two weeks ago I attended the RMLL conference. As usual this was quite interesting, and an occasion to show Haiku to more people in the free software community. We got only about 10 persons attending our conference and 4 attending our workshop on making Haiku packages. However, the main event was the “Libre Village” where we got to meet people and try to get as much of them as possible to try Haiku. I played Critical Mass with some people there, and also helped porting PyTouhou to Haiku.
Hey everyone!
Here’s a quick update for week #12.
TL;DR - The decompression process fails because the archive is present in a location that isn’t mapped by the MMU and subsequently allocated for the zlib output stream. No solutions have been discussed yet. It shouldn’t be long till the kernel is running hopefully :).
Hello Everyone!
I am working on porting Libusb to Haiku as part of Google Summer of Code, and here is a progress report on the work done till now.
Hey everyone!
Here’s the update for week #11.
TL;DR - Haiku faults when trying to find the floppyboot archive present in stage2 loader. There seems to be a difference in few offsets/sizes, which causes different bytes to be read every time the loader tries to detect the archive.
Hello there!
Few things to mention this week.
The 1.4.1 version of HaikuWebkit with the new drawing code is available in the nightlies. While it seems to work better in many cases, there will likely be a few regressions, please give it a test run and report any rendering problem you get.
With this released, I started the work on getting WebKit2 to build. Following the advise from one of the webkit-gtk developers in last week update comments, I’m starting with a port that will use UNIX Domain Sockets.
Hello,
I’m currently working on a Golang port for Haiku as part of Google Summer of Code. Since the last blog post, there has been some progress: simple Golang programs can now be compiled and run.
Hey everyone!
Here’s the update for week #10. Sorry about the delay in posting there - I had some issues logging into the website over past few days.
TL;DR - MMU is enabled and now working!
Hello everyone,
Things are rather quiet on the WebKit side this week. I’m reviewing and fixing the remaining bugs with the new drawing code, which is now working rather well. On the WebKit side, I have implemented a limited form of transform support for regions (only handling translation and scaling, not shear and rotations), which has very good results. As a consequence, we now have mostly correct drawing and quite good performance. Before I do a release (I know the version in current nightlies is quite outdated now), I want to fix one more bug, which is the lack of video display on youtube. This is probably a simple fix once I understand why the current code isn’t working anymore.
Hello world, another update!
The most exciting news this week is that I enabled the CSS JIT on Haiku. This is a new feature in WebKit that applies the same optimization techniques used for JavaScript, to CSS. CSS is becoming a complex language, and matching elements in the page with CSS rules and selectors can take a lot of time with complex stylesheets. WebKit will now use a JIT to compile CSS rules, which allows faster matching, and thus faster layout and rendering of the page. Since this uses mostly the same code as JS, enabling it was just a matter of switching the flag on in the webkit compile-time configuration.
