The rtems_test_pause() and rtems_test_pause_and_screen_number() macros
had different implementations depending on the RTEMS_TEST_NO_PAUSE
define. This define was defined to 1 by default. The user was able to
change this via the undocumented --disable-test-no-pause configure
command line option.
Pausing tests and waiting for user input contradicts the goal of having
automated test runs. Remove this feature.
Update #3818.
Rename source files to use a %.c -> %.o and %.cc -> %.o pattern. Use
*.cc for C++ source files instead of *.cpp to be in line with other C++
source files.
Update #3818.
This simplifies the build process. Do not generate the archive content
through the build system. Let the version control system deal with
symbolic links.
Update #3818.
Output only the basename of source files to be independent of the build
system source paths.
In the future it may be better to use the GCC -fmacro-prefix-map option.
This option is available in GCC 8 and later. It is not yet available in
clang.
Update #3818.
This partially reverts commit 7ec08391fe.
Since the RTEMS_DEFINE_GLOBAL_SYMBOL_IN_SECTION() cannot control the
alignment of the symbol it cannot be used to define the begin of a
linker set. File scope basic __asm__ statements cannot have operands,
so there is no way to specify the desired alignment.
Integrate parts of this commit:
This commit brings in a new refactored TCP stack
called Rack. Rack includes the following features: - A different SACK
processing scheme (the old sack structures are not used). - RACK (Recent
acknowledgment) where counting dup-acks is no longer done instead time
is used to knwo when to retransmit. (see the I-D) - TLP (Tail Loss
Probe) where we will probe for tail-losses to attempt to try not to take
a retransmit time-out. (see the I-D) - Burst mitigation using TCPHTPS -
PRR (partial rate reduction) see the RFC.
Once built into your kernel, you can select this stack by either
socket option with the name of the stack is "rack" or by setting
the global sysctl so the default is rack.
Note that any connection that does not support SACK will be kicked
back to the "default" base FreeBSD stack (currently known as "default").
To build this into your kernel you will need to enable in your
kernel:
makeoptions WITH_EXTRA_TCP_STACKS=1
options TCPHPTS
