* include/bsp.h: Disabled redefinition of CONSOLE_DRIVER_TABLE_ENTRY. Some "FIXME:" comments added. * console/config.c: New file. Definitions of externs referenced from libbsp/shared/console.c. * console/Makefile.am: Changed VPATH to point to libbsp/shared. Added config.c to C_FILES and EXTRA_DIST.
# # $Id$ # Board Support Package library This directory contains the source for the libbsp.a library. For each supported board $(RTEMS_BSP) there is a standard set of functions which must be provided in the BSP: + start up initialization + exit support + set vector + console IO support + drivers In addition, the BSP also determines the memory usage by providing any necessary linker scripts. There are also "generic" drivers in this directory. Currently they are shmdr and stubdr. Some of the supplied generic drivers (for example, shared memory) require target board specific support routines. NOTE: The library libbsp.a is actually built by $(RTEMS_BSP)/wrapup/Makefile. To execute all of the test in the RTEMS Tests Suites the following device drivers must be supplied: + Clock Tick + IO Driver Support + Timer + Shared Memory Driver Support The Timer Driver is used only by the Timing Test Suite (c/src/tests/tmtests/*). These tests are used to generate the execution times for RTEMS found in the flyers. It is recommended that these tests be run to verify a port to a new CPU or with a newly developed BSP. Looking at the times as compared to a known CPU and target can yield insights into potential performance problems in either the port, the BSP, or the target hardware. The Shared Memory Support is only required to execute the Multiprocessor Test Suite (c/src/tests/mptests/*). Multiprocessing is not a required part of a BSP.
