2023-01-24tm27: Avoid function pointer castsSebastian Huber1-1/+1
Add TM27_USE_VECTOR_HANDLER to select the interrupt handler type used by the <tm27.h> implementation. Close #4820.
2018-01-25Remove make preinstallChris Johns1-0/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

* include/bsp.h (Clear_tm27_intr): Stop the timer and disable the interrupt. This was not quite right before and we were getting uncontrolled interrupt nesting in tm27. * timer/timer.c (Timer_Initialize): Added an extra reset and changed the ITMR register so we will never get an interrupt. (Read_timer): Fixed so the timer actually stops before it is read. Before some times reported were outraguously high. * start/start.S: Major clean including using stack in linkcmds, deleting unused code, and zeroing the BSS using the linkcmds information. * startup/linkcmds: Put heap in lower memory than workspace and move _clear_end so both are zeroed.

* include/bsp.h, timer/timer.c: Updated so timer appears to work and support tm27. I would prefer to time a software interrupt rather than an use an extra timer though.

* README: Updated. We are now vectoring a clock tick ISR handler. But RTEMS is not returning from the ISR properly. * clock/clockdrv.c: Now causes interrupts but has not been calibrated. * include/bsp.h: Use <libcpu/tx3904.h> * startup/Makefile.am: Add setvec.c from shared. * startup/bspstart.c: Initialize the status register (SR) so no interrupts are masked but global interrupts (SR_IEC) are off. Added call to install the ISR prologue code. * wrapup/Makefile.am: Pick up more pieces from libcpu.

1999-11-17Updated copyright notice.Joel Sherrill1-2/+1
1998-04-15Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1-6/+0
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.
1998-03-21Switch to using a shared main() for all of the embedded BSPsJoel Sherrill1-2/+2
based on the GNU tools. This usually involved correcting the type of bsp_start(), bsp_cleanup(), adjusting the start code to call the right start routine (the shared boot_card()), and then removing code from bsp_start() which was performed in the new boot_card()/main() path.

1997-04-07added initialization of variable to eliminate warning.Joel Sherrill1-1/+1
1995-09-11The word "RTEMS" almost completely removed from the core.Joel Sherrill1-0/+20
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.
