- Implement a per line transmit FIFO to properly reflect the DHU real hardware
- Output is rate limited based on the programmed port speeds
- Properly abort programmed output
As reported and discussed in #600 and #588
Previously the CPU model was only being set when the CPU ROM was
implicitly loaded from the internal ROM image at boot time. Other
loading of ROM code never set the configured model correctly.
- Windows did not validate that the a segment size was correct.
- Add shared memory object name to the management structure
- Linux shared memory object names must start with a /
- Linux umask setting to assign permissions
- Add textual explanations for failure cases
Backed out commit 484889ea5a since the overflow of the timespec tv_nsec
field was the real cause of the problem. No need for an extra mutex.
As reported in #595
It seems that the prior use of sim_asynch_lock RECURSIVE mutex could
cause a pthread_cond_timedwait() failure with EINVAL returned.
As discussed in #595
Some git capable environments on Windows don't honor the installed git
hook scripts in the repository. Now that, if we're working within a git repo,
we force a working version of git to be installed in the runtime path. We
leverage that to force a validation of the commit id on each build.
- All projects use identical include directories, library definitions and
library directories.
- Remove attempts to add XP support to projects that were converted to
.vcxproj for post VC2008 versions of Visual Studio.
- Require that git be available when building within a git repository
working directory.
Also:
- Enhance SHOW MUX to support "SHOW MUX <dev>"
- Fix potential null pointer dereference with unusual ATTACH combinations
- Allow BPS factor to change without specifying an explicit speed.
Some devices have dedicated units that perform various independent
functions (often timing) that are independent of the primary device unit
which is ATTACHed. This services to help interpret debug information
that may be produced.
previously, programmed I/O was initiated and completed as the time it was
initiated. Now that output is rate limited to the port selected speeds the
output buffer can fill and I/O be dropped when the buffer was full. Now all
output is setup in the register write path and completed in the unit service
path. A separate transmit service unit now performs all transmit I/O
completion activity.
