Notepads where a feature of RTEMS' tasks that simply functioned in the same way as POSIX keys or threaded local storage (TLS). They were introduced well before per task variables, which are also deprecated, and were barely used in favor of their POSIX alternatives. In addition to their scarce usage, Notepads took up unnecessary memory. For each task: - 16 32-bit integers were allocated. - A total of 64 bytes per task per thread. This is especially critical in low memory and safety-critical applications. They are also defined as uint32_t, and therefore are not guaranteed to hold a pointer. Lastly, they are not portable solutions for SMP and uniprocessor systems, like POSIX keys and TLS. updates #2493.

The tests were designed to operate in a very controlled environment. If
|
|
one uses interrupt-driven console output, then tasks will block unexpectedly
|
|
when a buffer filles and interrupts will perturb with the task execution order.
|
|
|
|
The tmtests should only be run with all interrupt sources disabled using
|
|
polled IO.
|
|
|
|
The following is a list of reported failures from running the tests on
|
|
a board with interrupt driven console IO. These problems do not
|
|
occur when using polled IO.

tm03, tm04, tm05, tm07, tm11, tm12, tm13, tm14, tm15, tm16, tm17,
|
|
tm19, tm22, tm23, tm24 - All hit my breakpoint at
|
|
_Internal_error_Occurred.
|
|
|
|
tm20, tm27 - hang in middle of tests.
|
|
tm26 - hangs at end of tests.
|

|
sp02 - Gets through some tests, then attempts to execute code at
|
|
location 0.

sp04 - hangs at end of tests.

sp06 - rtems_task_restart of TA3 FAILED -- expected (0) got (4)
|
|
sp14 - hang in middle of tests
|
|
sp13, sp15 - terminate properly, but output at end is missing.
|
|
sp16 - _Internal_error_Occurred.

middle of test.
