====== Stefan Hajnoczi: GDB Remote Debugging ====== ===== Week 9 ===== **Milestones:** * [b44] Tested and clean for mainline review. ==== Mon 21 Jul ==== Git commit: * [[http://git.etherboot.org/?p=people/stefanha/gpxe.git;a=commit;h=b88a864e951d4588267131fde00c42464e6c021c|[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. This commit rips out uhmalloc and rewrites DMA mapping to use malloc's allocator. ==== Tue 22 Jul ==== Git commit: * [[http://git.etherboot.org/?p=people/stefanha/gpxe.git;a=commit;h=1bbaa358c63df64bab38c45ad11fc93ea2a8e510|[prefix] Reasonable value for lkrn initrd_addr_max]] 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''. Next steps: * [roundup] Set up and document roundup installation, email mdc with details * [DMA] DMA pool API so drivers can reserve DMA buffers on ''open()''. * [b44] Cleanup, testing, performance. * [shutdown] Remove gPXE allocated memory and free up PXE+UNDI, if necessary. * [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.
