[GSoC 2014 : ARM Port] Week #16

Hello everyone!
Here's a quick update for week 16. I didn't have internet access over the past few days due to a technical issue with my ISP and hence the delayed report.

TL;DR – The patch to prevent the kernel from overwriting the loader was merged last week. The next issues that need to be tackled are the KDL faulting when printing the backtrace and fixing an assertion that fails when initializing virtual memory.

Hello everyone!
TL;DR - It was decided that reserving space for the kernel instead of moving the entire memory map to a higher location. I’ve been working on that for most of last week and I think it would take a good part of this week to complete it since I seem to be running into many issues.

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.

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 :).

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.

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!
