8cbe4ba0bd VAX: Properly inline memory reference functions for performance. Fix #169 2014-12-31 13:25:49 -08:00

7256e0908c PDP11: Simplified idle call logic to leave the idle decision to sim_idle(). 
Removed the unused references to wait_enable which the comments suggest was related to an old style idle.

549779fb10 PDP10, PDP11, VAX: Adjusted KDP, DUP and DMR/DMC devices to be better behaved when the simulated system is idling. 
This may not completely fix the problem identified in issue #99, but it should help

368a5f6998 PDP11, VAX780: Fix DEUNA handling of incoming packets which are dropped into multiple receive buffers. 
Make sure to properly support multiple receive buffers by correctly setting the data length read and the appropriate buffer descriptor status bits for each buffer descriptor that is used to hold a packet.

611a7e94f0 SCP: Added a Remote Console Master Mode. 
This capability will allow a GDB RSB stub to be created to support dynamic debugging of code running in a simulator.

This capability will also allow a complete front panel emulation system to operate a simulator.

This capability is engaged in a simulator by:
     sim> set remote telnet=remoteconsoleport#
     sim> set console telnet=consoleport#
     sim> set remote master

Master mode will provide a TCP session which accepts SCP commands that allow full control of the simulator.

4c55f1af0c VAX: Make sure that Ultrix 1.X specific behaviors are only in effect with that OS 2014-07-17 10:04:40 -07:00
Mark Pizzolato
4d817f1deb VAX: Added support for the DEQNA device on Ultrix 1.x. Henry Bent observed that the deqna driver in this OS counted on older DEQNA firmware which automatically enabled interrupts after a software reset. 
CPU Idle detection for this OS is now supported and the combination of SET CPU IDLE=ULTRIX-1.X and explicitly using a DEQNA device (SET XQ TYPE=DEQNA) will enable the automatic enabling of device interrupt generation.

e9b312f26a PDP11, VAX: Added Ethernet packet transmission throttling support to XQ and XU devices. 
Migrated the XQ help to the hierarchical help model.  This is a work in progress which will eventually merge much from 0readme_ethernet.txt into the device help.

6ce8d99cd8 SCP: Added generic output routine sim_printf to output to stdout and sim_log (and sim_deb when enabled) 
The goals here being to simplify calling code while getting consistent output delivered everywhere it may be useful.

Modified most places which explicitly used sim_log or merely called printf to now avoid doing that and merely call sim_printf().

59d0602b0d PDP8: Add device buffer flush capability and keep track of data written state in the device buffer. Fixes #87 
Finishing the last DECtape device which was missed when this functionality was added to pdp11_dt, pdp18b_dt and pdp8_dt
in commits: 2934112a70 and c9e8121c16

Cleaned up the pdp11, pdp18b and other pdp8 implementations to make backporting cleaner.
Made sure that buffer flushing happens correctly when simulation returns to the sim> prompt.
