6bf92de3db All VAX: Also return correct Unibus/Qbus vectors for devices with more than one vector. Fix #241 2015-10-14 13:12:51 -07:00

73d7aee71f SCP: Add printf style format argument validation for all functions which take printf arguments. 
These include: sim_printf(), sim_messagef(), Fprint() and sim_debug().

Fix current use of these functions which had invalid arguments.

ed57f061e2 All VAX: Always return the correct Qbus/Unibus interrupt vector bits for all devices. Fix #239 
Vector values contained in device information blocks are the true bus relative vector values.  CPU specific biased vector values are produced by the respective vector fetching logic and vector values are limited to 9 bits with <1:0> = 0 as specified in both the Unibus and Qbus documents.

8bb494036c PDP11: Add provision in the DL device simulation to support bursts of input data to avoid reporting character overruns on the serial port. 
Overruns can happen on simulated MUX lines using TCP since multiple characters can arrive in a single network packet.  Overruns still are reported if previous input characters haven't been read within 500ms.  Edmund Marr reported this problem.

1fb209c275 SOCKETS: Cleanup, simplify and extend the sim_sock API set. 
Cleanup/Simplification by:
	1) removing irrelevant master flag variable from sim_close_sock and thus sim_err_sock
	2) change previous boolean feature arguments (datagram, nodelay, reuseaddr) to flag bits in a single option argument.  This allows for features to be added by new flag bits which don't change the calling signatures.
	3) changed all status returns to be int (vs t_stat) with success being 0 and error being -1
	4) removed unneeded simh specific type references to allow sim_sock to be used by n
Extended API by providing flags to influence socket setup/behavior:
	SIM_SOCK_OPT_REUSEADDR	Retains prior behavior when sim_switches had -U set
	SIM_SOCK_OPT_DATAGRAM	UDP socket setup provided for when prior datagram argument was specified
	SIM_SOCK_OPT_NODELAY		TCP Nagle disable provided for when prior nodelay argument was specified
	SIM_SOCK_OPT_BLOCKING	Blocking socket mode (detault is non blocking)

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.
