"Yes, I've already fixed all these bugs and more. I've left the initialisers fully static and binary compatible"

Cool. I checked CVS but didn't realise you had other outstanding changes. ...

This has been bugging me, so I went back over those mutex initialisers. There are still some problems:

1) __owner is not initialised.
2) __mutex is set to 0
3) __attr is set to NULL

#1 is easy ...

If you're getting errors during mmap related operations, keep an eye on the kernel log and see if there are any warning: I put a few in to log un-handled features.

Oh fancy that, yet another broken source that assume Linux. It might be worth checking that _GNU_SOURCE is not defined, which *might* make DirectFB behave and not ass-u-me that it's running on top of ...

It's all right anyway, you can totally ignore this. I've confused read_pos_p() with read_phys_blocks(): read_pos_p() will hit maybe_cached_read() (& ditto write_pos_p()) inside AFS eventually anyw ...

I'd have to have a machine running Syllable and a development environment for that :)

PostForum: Bugs   Posted: Fri Apr 13, 2012 8:36 am   Subject: msync() with MS_ASYNC flag is not reliable
#2 above is a non-issue:

a) The process calls msync(MS_ASYNC) from user space
b) The kernel invokes aio_write_pos_p()
c) aio_write_pos_p() calls aio_insert_op(), which checks for a current AIO co ...

I just noticed that do_aio_worker() uses read_pos_p() and write_pos_p() for the async I/O operations, which means it does not pass through the block cache. It should probably be using maybe_cached_rea ...

On the flip side, XSDL is probably one of the simplest, or at least easiest to understand, of all the X servers. You could probably use it as a (very rough) template for a [i]native[/i] Syllable serve ...

PostForum: Bugs   Posted: Tue Oct 11, 2011 3:40 pm   Subject: msync() with MS_ASYNC flag is not reliable
Flicking over some (of my own) code earlier I noticed that msync() makes use of aio_write_pos_p() to queue an async write in an attempt to clear the flush. There are two immediate problems I noticed: ...

I've hacked on the sources and got them to compile. The latest are in BitBucket and I've also added a small patch in the Mercurial repository for the system header changes, which are surprisingly smal ...

I have the oriiginal tarball here myself. The includes are roughly hacked versions: they'll need to be merged with the current CVS versions. That's probably a fair amount of work.

Yeah. I'll drop one on later myself if you like.

Note that there is a lot of work required to even get that code to compile now, as the headers have all changed beneath it and some changes were los ...
