| **Committed switch from uhmalloc to hmalloc**. For the DMA mapping work, I reused umalloc's memory allocator and called it uhmalloc. After discussion with mcb30 and mdc, it turned out that the malloc allocator is better suited. This commit rips out uhmalloc and rewrites DMA mapping to use malloc's allocator. | **Committed switch from uhmalloc to hmalloc**.

| - | Next steps: | + | ==== Tue 22 Jul ==== |
| - | * [roundup] Set up and document roundup installation, email mdc with details | + | Git commit: |
| - | * [DMA] DMA pool API so drivers can reserve DMA buffers on ''open()''. | + | * [[http://git.etherboot.org/?p=people/stefanha/gpxe.git;a=commit;h=1bbaa358c63df64bab38c45ad11fc93ea2a8e510|[prefix] Reasonable value for lkrn initrd_addr_max]] |
| - | * [b44] Cleanup, testing, performance. | + | |
| - | * [shutdown] Remove gPXE allocated memory and free up PXE+UNDI, if necessary. | + | I've been busy most of the day since I'll be travelling tomorrow. HPA informed me of a bug in the updated bzImage work I did. Luckily the source of the bug was already identified, I simply needed to change the hardcoded ''initrd_addr_max'' value in ''arch/i386/prefix/lkrnprefix.S''. |
| - | * [bzImage] Expand the heap size to the full 64K segment when loading a bzImage kernel with version 2.02 or higher. | + | |
| - | * [GDB] Real-mode remote debugging. | + | ==== Fri 25 Jul ==== |

| + | |||
| + | **DMA mapping work continues**. I'm reworking things from all sides hmalloc, dma_mapping, and b44. Hopefully it will converge soon :-). | ||
| + | |||
| + | ==== Sun 27 Jul ==== | ||
| + | **The Roundup issue tracker** is close to ready. Mdc and I have spent some time setting up the [[http://roundup.sf.net/|Roundup issue tracker]] to improve our grasp on patches and bugs. | ||
| + | |||
| + | Currently we suffer the problem that patches are easily forgotten on the mailing list if the developers are busy. An issue tracker provides a better overview of outstanding patches that need to be reviewed. | ||
| + | |||
| + | Bug reports are also streamlined by the new system. This will be especially useful in the coming months as Etherboot.org becomes more visible and new users try it. | ||
