* Patch to add return status to rtems_termios_enqueue_raw_characters fromJoel Sherrill1998-05-202-2/+4
| | | | | | | | | | | | | | | Eric Norum per request from Geoffroy Montel: > The rtems_termios_enqueue_raw_characters function type is void. > The problem is that I can't return an error message if the input > buffer is full. > Could we add a return value? Sure, but what would you do with the overflow indication? POSIX says, ``when the input limit is reached, the saved characters are thrown away without notice''. Anyhow, the change is so small I've done it and enclosed the patch.

* Cosmetic fix from Eric Norum:Joel Sherrill1998-04-271-1/+1
| | | | | | This makes the headings line up above the columns a little better. Now that it's so easy to include/exclude the stack check code I find myself adding it to all my `debug' targets.
* Fixed CVS IdJoel Sherrill1998-04-271-1/+1
|
* Added numerous entries to make the memory calculation more accurate:Joel Sherrill1998-04-271-1/+67
| | | | | | | | | | | | | + POSIX threads + Ada tasks + POSIX threads API support + POSIX condition variables + POSIX keys (still do not account for data fields) + POSIX mutexes + POSIX queued signals + added macro for extra memory for task stacks + default value for CONFIGURE_MAXIMUM_FAKE_ADA_TASKS + extra memory for Ada task stacks
* Moved POSIX_signals_Siginfo_node structure definition to headers/psignal.hJoel Sherrill1998-04-271-5/+1
| | | | so confdefs.h could see it.
* Changed __POSIX_SIGNALS_h to __RTEMS_POSIX_SIGNALS_h to avoid conflict withJoel Sherrill1998-04-271-2/+7
| | | | | | | the system signals.h file. Moved POSIX_signals_Siginfo_node type definition to this file to allow confdefs.h to know the size per queued signal.
* rtems_libio_number_iops is now defined in confdefs.h so the maximumJoel Sherrill1998-04-181-1/+1
| | | | file descriptors is user configurable.
* Changed to account for libio's maximum_semaphores as well as itsJoel Sherrill1998-04-181-1/+5
| | | | | | memory requirements. Also added variable to tell libio how many file descriptors to allocate.
* Fixed so this would compile without warning.Joel Sherrill1998-04-151-0/+2
|
* Added bh, ch, dh, bl, cl, and dl register macros.Joel Sherrill1998-04-152-0/+14
|
* Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1998-04-152-19/+9
| | | | | | | | | | | | code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
* Stack check now initialized as part of initial extension set.Joel Sherrill1998-04-153-0/+65
|
* Per suggestion from Eric Norum, went from one initial extension setJoel Sherrill1998-04-151-12/+13
| | | | | | to multiple. This lets the stack check extension be installed at system initialization time and avoids the BSP having to even know about its existence.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've gone through and cleaned up the TFTP driver so that it fits into the libio system. Here's the comment from the new driver: /* * Usage: * * To open `/bootfiles/image' on `hostname' for reading: * fd = open ("/TFTP/hostname/bootfiles/image", O_RDONLY); * * The `hostname' can be a symbolic name or four * dot-separated decimal values. * * To open a file on the host which supplied the BOOTP * information just leave the `hostname' part empty: * fd = open ("/TFTP//bootfiles/image", O_RDONLY); * */ You can `fopen' TFTP files the same way: fp = fopen (fullname, "r"); nread = fread (cbuf, sizeof cbuf[0], sizeof cbuf, fp); The diff's are included below. I've also modified the TFTP demo program and the bootstrap PROM example. They should be on my ftp site `soon'. The one thing I don't like is the way I had to do an end-run on the libio routines to get errno passed back from my driver to the application (since there are some errno codes that don't map to RTEMS status codes). My approach was to set errno in the driver and have the driver routine return an RTEMS status code that I `know' isn't in the errno_assoc[] in libio.c. Perhaps there should be an RTEMS_TRANPARENT_ERRNO status code (or something similar) which driver routines could return to indicate that the driver routine has set errno and that the libio routines shouldn't attempt to map the returned status code to errno. Actually, I think the entire I/O system needs looking at -- as you've already mentioned. The hacks I've dropped in to syscalls.c to make fstat work, for example, are *not* shining examples of good code......
