1999-03-17Unlimited objects patch from Chris Johns <ccj@acm.org>. Email follows:Joel Sherrill2-10/+36
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.
1998-06-18Modified _Objects_Is_class_valid() to correctly report that 0 wasJoel Sherrill1-1/+1
not a valid object class. This was discovered while looking for a bug reported by Jennifer.

1997-03-11modified _Chain_Insert_unprotected to have the form required to be usedJoel Sherrill1-2/+2
as the sole statement in an if or else statement
1996-09-06changed _TOD_Is_set from a function to a boolean variableJoel Sherrill1-9/+0
1996-08-13removed Thread_queue_Get_number_waitingMark Johannes1-9/+0
1996-05-31renamed _TOD_Ticks_since_boot as _Watchdog_Ticks_since_boot so the WatchdogJoel Sherrill1-1/+1
Handler could timestamp the starting and stopping of timers. Since TOD is built on top of Watchdog, this avoided a circular dependency.
1996-04-22made initialization routine a regular subroutineJoel Sherrill1-41/+0
1996-03-06Removed prototyes for static inline routines and moved the comments intoJoel Sherrill1-2/+2
the inline implementation. The impetus for this was twofold. First, it is incorrect to have static inline prototypes when using the macro implementation. Second, this reduced the number of lines in the include files seen by rtems.h by about 2000 lines. Next we restricted visibility for the inline routines to inside the executive itself EXCEPT for a handful of objects. This reduced the number of include files included by rtems.h by 40 files and reduced the lines in the include files seen by rtems.h by about 6000 lines. In total, these reduced the compile time of the entire RTEMS tree by 20%. This results in about 8 minutes savings on the SparcStation 10 morgana.
1996-02-21Removed the internal thread objects and dispersed its contents toJoel Sherrill1-0/+16
the thread handler (IDLE), MPCI object (SYSI now MP Receive) and initialize_executive_early (IO initialization). The SYSI task no longer exists in a single processor configuration. This reduces single processor Workspace requirements by a TCB and a stack which is often larger than the minimum stack size. Moving the IO initialization plus accompanying BSP hooks eliminated an initialization ordering problem in which a global task could be created before the MPCI was initialized.
1996-02-13changed post task extension from user set to api set and added flagJoel Sherrill1-9/+0
in each thread which must be set when the post switch extension is to be run.

single biggest changes were the expansion of the workspace size macro to include other types of objects and the increase in the minimum stack size for most CPUs.
1995-09-11The word "RTEMS" almost completely removed from the core.Joel Sherrill14-117/+199
Configuration Table Template file added and all tests modified to use this. All gvar.h and conftbl.h files removed from test directories. Configuration parameter maximum_devices added. Core semaphore and mutex handlers added and RTEMS API Semaphore Manager updated to reflect this. Initialization sequence changed to invoke API specific initialization routines. Initialization tasks table now owned by RTEMS Tasks Manager. Added user extension for post-switch. Utilized user extensions to implement API specific functionality like signal dispatching. Added extensions to the System Initialization Thread so that an API can register a function to be invoked while the system is being initialized. These are largely equivalent to the pre-driver and post-driver hooks. Added the Modules file oar-go32_p5, modified oar-go32, and modified the file make/custom/go32.cfg to look at an environment varable which determines what CPU model is being used. All BSPs updated to reflect named devices and clock driver's IOCTL used by the Shared Memory Driver. Also merged clock isr into main file and removed ckisr.c where possible. Updated spsize to reflect new and moved variables. Makefiles for the executive source and include files updated to show break down of files into Core, RTEMS API, and Neither. Header and inline files installed into subdirectory based on whether logically in the Core or a part of the RTEMS API.
1995-08-28Added unused priority ceiling parameter to rtems_semaphore_create.Joel Sherrill2-1/+10
Rearranged code to created thread handler routines to initialize, start, restart, and "close/delete" a thread. Made internal threads their own object class. This now uses the thread support routines for starting and initializing a thread. Insured deleted tasks are freed to the Inactive pool associated with the correct Information block. Added an RTEMS API specific data area to the thread control block. Beginnings of removing the word "rtems" from the core.
1995-08-23Support for variable length names added to Object Handler. This supportsJoel Sherrill1-26/+7
both fixed length "raw" names and strings from the API's point of view. Both inline and macro implementations were tested.
1995-08-22Merged PowerPC port as submitted by Andy Bray of I-CUBED, LtdJoel Sherrill6-6/+6
(andy@i-cubed.demon.co.uk). This initial submission is known to work on the IBM 403. It is thought to work on the Motorola 601, 603, and 604 although this remains to be tested. Another user -- Doug Currie (e@flavors.com) -- is interested in this work and will be testing it on the 604 using the Metrowerks C compiler and a different format assembly language.
1995-08-18+ Added object type field to object id.Joel Sherrill1-4/+17
+ Added name pointer to Object_Control. + Modified Object Open and Close to address name field. + Removed name as separate element from Thread and Proxy Control.
