Mon Jun 2 Git commit: 0004992b5bb35b4d5df324d8afffae04e3ee8285 I hit an interesting bug thing while writing the GDB stub test suite.

Mon Jun 16 The gdbstub2 branch is now ready for mainline review. Diffs against gPXE master are here.

Mon Jun 23 Git commit: [bzImage] Place our own stack to prevent clobbering Lilo bzImage problem identified. Lilo cannot boot gpxe.lkrn images. This happens because Lilo places gPXE's stack into the BIOS free memory area. gPXE uses the free memory area when decompressing and loading itself into memory. text/html 2008-07-08T06:57:10-07:00 http://etherboot.org/wiki/soc/2008/stefanha/journal/week6?rev=1215525430&do=diff Stefan Hajnoczi: GDB Remote Debugging Week 6 Milestones: * [b44] Tested and clean for mainline review. * [r-o-m] Fix known ROM-o-matic bugs.

Mon 21 Jul Git commit: * [hmalloc] Kill uhmalloc, use malloc's allocator instead 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.
