SATA AHCI Driver GSoC - Week 5 Update

From beginning of week I started reading more stuffs (core) about AHCI and trying to plan a road map which I will follow after making first version of AHCI driver. Throughout the week I made some progress with Interrupt Handler and AHCI port programming. Though I have finished port programming routine and next I will complete Interrupt Handler followed by Srb functions.

NTFS Write Support GSoC - Week 5

Progress

At the beginning of the week I finished cleaning up and committing the code I wrote related to extending a file's size. This took me a little longer than I expected and in the future I'm going to commit more often so I don't have this problem.

From there I added support for truncating files, with a couple of caveats. This is significant because it allows for opening a file in Notepad.exe, changing it, and saving it.

USB stack improvements GSoC - Week 5

Google SoC lwIP Report Week 5

Going into week 5, I started with a code-complete but very much incorrect implementation of the TDI_SEND and TDI_RECEIVE IRQ handlers. My TCP_CONTEXT data structure and the existing ADDRESS_FILE data structure both did not contain a way to keep track of pending IRQs, so I had no way of keeping track of outstanding pending IRQs and what connection contexts they were supposed to be associated with. Without a clear scheme for keeping track of the information, IRP pointers invariably got lost.

SATA AHCI Driver GSoC - Week 4 Update

This week I worked on AHCI IO Request Processing and FIS programming part. I implemented IO Queue, Slot distribution mechanism for AHCI requests. Updated Github's PR for next round of code review.Next I will be working on port programming i.e. telling the controller about the slots that I've allotted for IO request.
Very soon we will have a running AHCI device driver :D
