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/*).
