97ea1cf463 I7000: Fixed tape handling errors and coverity errors. 2019-06-09 15:22:11 -04:00

9ab8d0e91e TIMER: Add debug of all calibration decision variables default no idle skip 2019-06-08 16:38:15 -07:00

7bcf407fcc TIMER: Reorganize timer control variables to use a structure for each timer 
The original approach had separate parallel arrays for each relevant
state variable for each calibrated timer.  That worked when there were
only a few state variables, the state info for a timer belongs in a
structure.

09bbcb29d2 TAPE: Fix P7B reverse read logic for large records 
The earlier optimization to address P7B reverse read performance
didn't properly back up under some circumstances.

As potentially reported in #707

53ad66f57e PDP10: Fix rdtim to properly compute the value 
The correct solution adds the elapsed interval rather than the remaining
interval value.

9514ea5a58 TIMER: Stabilize run away clock calibration conditions 
- Adjust calibration parameters to properly record catchup variables for
  odd condition cases.
- Disable idle percentage calibration skipping until the correct set of
  calibration variables are available.
- When a pre-calibrate operation has been performed, make the results
  visible in the output of SHOW CLOCK

As discussed in #705 and #699

0195bbda4b TIMER: Fix missing catchup ticks for VAX simulators when idling 
- MicroVAX I, II and 3900 don't have a DONE bit in the clock status
  register, so sim_rtcn_tick_ack() wasn't being called to acknowledge
  clock ticks.
- Timer catchup tick criteria didn't work unless the host had a slow
  clock tick.

45d8c908ba PDP10: Leverage the internal calibrated timer for accurate wall clock timing 
Avoid the common situation on with this simulator whereby the programmatic
interval timer is being used for intervals which change often.  The internal
calibrated timing routines depend on consistent rate for the calibrated device.

48db10994d TIMER: Calibrated clock fixes 
- Properly handle clock transitions when control flows back and forth
  between instruction execution and simh commands.
- Changed Internal Timer from 10 Hz to the MAX(100Hz, HostOSClockHz)
- Changed default idle calibration percent to 50%
- Make sure that error cases (backwards and gap too big) properly advance
  the real time while avoiding calibration.
- Fix selection of the calibrated clock.
- Fix logic that sets the idle percentage that controls calibration.

b1f3441f7f ETHER: Start newly opened interfaces blocking all packets 
A device simulator is responsible for specifying exactly what categories of
packets it wants to receive.  It should do that after having opened the device.
This change avoids collecting packets that aren't actually interesting until
after the device designates which packets it is interested in.
