And if it might be wise to take that and use - it in GNU Mach. There is no need to worry about purely internal API's, - but the external ones shouldn't require any major changes. - - * Write a list of all functions provided by the host dependant code in - GNU Mach that gets used in the non-host specific code (kernel, IPC and - VM). - - * Once we have decided what the new internal API should look like, make a - list of the new API and the old one, and try to make things as - compatible as possible, but not at the expense of anything. - - * Implement Migrating Threads - - * Migrating Threads (MT) could improve IPC performance and making easier - the work of the scheduler. For more information, check - <http://www.usenix.org/publications/library/proceedings/sf94/ford.html> - - * Improve the external pagers interface - - * Implement read-ahead (huge I/O improvements expected). - - * Making this interface synchronous should improve I/O performance - significantly, without (almost) any drawbacks (we also get some - advantage from MT's). - - * Implement more paging eviction policies, so they fit better with usual - behaviour of the pagers. - - * Implement resource accounting for external pagers. - - * VM - - * Put it on user level (?) - - * Clean up the mess. - - * Provide a fast way to read/write from/to a memory object. - - * Simplify/normalise the code. - - * Simplify the IPC Semantics - - * There are a lot of things in GNU Mach's IPC that we don't need. Track - down those things, and get rid of them without requiring many changes - in the Hurd (the changes will affect MiG, but that is OK). - - * Temporary mappings for Client-Server memory transfers - - * Extend Mach's IPC to provide some kind of object which can represent a - range of memory that can temporarily be mapped into the servers address - space for sending/receiving data. This would allow us to avoid - excessive memory copies. - - * Find a new way to work with unaligned memory. - - * GDB remote debugging support - - * Implement support for GDB debugging via serial line and/or network. - Maybe this can be done together with the host-specific work above. - - See [[GDB_stubs]]. - - * Make it run as a [[UNIX]]/Linux executable. - - * Neal: - - <neal> here's a fun project: port the mach interface to Linux - <neal> (e.g., via kernel modifications) - <neal> or, to posix/glibc - <neal> (mmap, some minimal ptrace, etc.) - - * From the [Hurd bits at - sourceforge.net](http://sourceforge.net/projects/hurd): - <http://hurd.cvs.sourceforge.net/hurd/gnumach-otop/>, started by John - Tobey.
