| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: a posix thread which is created by pthread_attr_init(&tattr); pthread_attr_setinheritsched(&tattr, PTHREAD_EXPLICIT_SCHED); pthread_attr_setschedpolicy(&tattr, SCHED_RR); pthread_create(&th, &tattr, func, arg); has a first timeslice of 2^32 ticks (changing a running thread to SCHED_RR id ok). I use RTEMS-4.0.0. I am not sure if the problem exists in the current CVS head revision. If it's not fixed, the patch at the end should do it.

I cannot remember the exact workings of the id values and the local_table. I might have changed the nature from the pre-unlimited change.

A static local variable `null_local_table' has been added. This variable is always set to NULL. The `**local_table' element of the information structure is set to point to this variable earily in the initialisation. If the object type has more than 0 elements the `local_table' element is updated. All object types which have 0 elements reference `null_local_table'. This change fixes the problem sp09 found yet does not add any extra processing to the critical `_Objects_Get_local_object' function. ---- CVS log ----
* Unlimited objects patch from Chris Johns <ccj@acm.org>. Email follows:Joel Sherrill1999-03-171-81/+483
| | | | | | | | | | | | | | | | | | | | | | | | | First, the unlimited patch. I have compiled the unlmited patch for the Linux posix BSP only and it seems to work cleanly. I would like a really major application run on this change before commiting as the changes are very core and significant. I am currently building all the tests to run. I have no targets suitable to test on at the moment. I have tested the patch for inline functions and macros. Turning macros on has found some core bugs. I have fixed these but have not run all the tests. Please review the patch for these changes. They are: 1) The conditional compilation for MP support broke the core messages code. You cannot embed a conditional macro in another macro. The Send and Urgent Send calls are macros. 2) User extensions handler initialisation now has two parameters. I have updated the macros to support the extra parameter. The patch also contains the gcc-target-default.cfg fix required to build the kernel. More of a by product than a fix for you.

* Added --disable-multiprocessing flag and modified a lot of files to makeJoel Sherrill1998-11-237-4/+47

* Patch from Eric Norum <eric@skatter.usask.ca>:Joel Sherrill1998-11-191-0/+8
| | | | | | | | | | | | | | | 1) Socket timeout field changed from `short' to `long'. This makes longer timeouts possible. With a 1 kHz system clock the old system allowed timeouts only up to a little over 30 seconds! This change is a slightly cleaned-up version of the patch proposed by Ian Lance Taylor. 2) Major changes to BOOTP/DHCP reply handling. Now supports much of RFC2132. These changes were done at the request of, and with the assistance of, Erik Ivanenko. If you're making changes, you might want to change the network supplement Essentially just do a global search and replace of BOOTP with BOOTP/DHCP.

* Modified calls to _Thread_Change_priority to take a third argument. The newJoel Sherrill1997-03-082-10/+39
| | | | | | | | | argument indicates whether the task is to be placed at the head or tail of its priority fifo when it is lowering its own priority. POSIX normally follows the RTEMS API conventions but GNAT expects that all lowering of a task's priority by the task itself will result in being placed at the head of the priority FIFO. Normally, this would only occur as the result of lose of inherited priority.
