[GSoC 2018: SDHCI MMC Driver]: Third Phase Outline

Blog post by krish_iyer on Thu, 2018-07-12 10:52

So here we are in the final week of the second phase of this project. I would like to address what was planned for this phase and what we have achieved and will proceed to plan for the third phase. Second Phase Highlights We were successful in register mapping through MMUIO. We have created a bus manager but not linked with controller ATM. Interrupts have not been implemented but also not required in this phase.

[GSoC 2018: SDHCI MMC Driver]: Week #8

Blog post by krish_iyer on Mon, 2018-07-09 20:09

Hey guys! Last week we have improved the code and made it more readable. We have completed the reset and clock sequence and proceed with power sequence. In the 4th step of the sequence, it asks to get the Operation Conditions Register(OCR) value of SD card. In the SD host controller spec, in command register there is command index bits which mention about setting up command number specified in bits 45-40 of the command-format in SD Memory Card Physical Layer Specification.

[GSoC 2018 - TrackGit] Progress Report 10

Blog post by hrily on Mon, 2018-07-09 18:05

This is the tenth progress report for TrackGit project. I did the following in last week. Implemented Show conflicts Window Last week I implemented Pull command. While pulling changes, sometimes there might be conflicts while merging the changes. These conflicts are shown when pull command execution is finished. In addition to that, I implemented a “Show conflicts” option to see the current conflicting files in the repository. This option is only shown when there are conflicts in the repository.

LibreOffice for Haiku, a not-so-short story

Blog post by KapiX on Sun, 2018-07-08 02:16

As many of you are already aware, LibreOffice is now available on Haiku. This has been a long journey that has started for me around 2014, when I was looking for things I could do for the project. LibreOffice port was one of those things. It seemed to need so much effort, most people didn’t even want to start. That’s understandable given people were busy developing the OS. However, it’s not the first time someone tried to do it.

The State of Rust on Haiku - July 2018

Blog post by nielx on Thu, 2018-07-05 07:31

The Rust programming language belongs to the category of modern programming languages that aim to provide a reliable and safe alternative to C and C++. In the past few years, few people have been working on getting the compiler, and the other build tools to our platform. And in fact, since Rust 1.0 there have been reasonably working binary packages for building Rust projects on Haiku. With the recent addition of Rust 1.

[GSoC 2018: SDHCI MMC Driver]: Week #7

Finally, we got the register mapping work and they are responsive, we have tested by enabling software reset bit and it has all the default values of registers which are set by Qemu except the present state register and capabilities register. These both should be left unaffected as mentioned in the spec. We are following SD Host specification version 1.00 for now, which also doesn’t support UHS but Qemu seems to be supporting it well.

[GSoC 2018: XFS support] Week #7 and #8

Blog post by abx1 on Mon, 2018-07-02 21:28

Hi all, I have been reading through the XFS documentation and looking more into the on-disk structures. Previously, I had looked into AG inode management, but not inode core structure. So I thought it would be better to look into how files, directories and links are stored on disk with inodes. I implemented struct xfs_dinode_core, the core part of the inode, which includes stat data information about data and attribute forks.

Haiku monthly activity report - 06/2018

Blog post by PulkoMandy on Mon, 2018-07-02 13:26

Hi there, I'm back for an activity report! Let's see what happened last month. This report covers hrev51986-52054 Donations and funding I just wanted to note that the 5 Haiku contributors who joined Liberapay are now part of a "team". In case you missed it, Liberapay is a way to donate money to some Haiku contributors directly. They are an open source project, funded themselves by donations from their users, and with an interesting approach to funding free software and other commons creations.

[GSoC 2018 - TrackGit] Progress Report 9

Blog post by hrily on Mon, 2018-07-02 18:00

This is the ninth progress report for TrackGit project. I did the following in last week. Implemented Pull command I implemented the equivalent of git pull. The implementation was a little trickier as there was no direct API for pull in libgit2. The git pull command is combination of a fetch and then a merge. In merge there are three cases: Repository up to date Fast forward Merge commit The merge commit can lead to conflicts.

[GSoC 2018: SDHCI MMC Driver]: Week #6

Blog post by krish_iyer on Tue, 2018-06-26 15:04

Hello everyone! Here’s the update of week #6, in the last update we were not able to access the registers. When we tried mapping it, there were all zeros. so we knew there’s something wrong in the way we were accessing the register and in between this we got to know that qemu emulation for sdhc hardware only supports spec version 2 and 3 and the spec which we intended to implement was 4.
