I posted my VHD file to gist:
gist.github.com/sirop/dd4a8b7c3f7af1953913

You probably mean this line:
Code:
.... (QcountTag, x"02", ClockLowTag, x"01", QcounterAddr&PadT, QCounterNumRegs, x"00", QCounterMPBitMask), ....

According to tom-itx.no-ip.biz:81/~webpage/emc/xilinx...14_install_index.php these members are:
'TAG, VERSION, CLOCK, INSTANCES, BASE ADDRESS, NUMBER OF REGISTERS, STRIDES, MPBITMASK'

As I understand, I have only one Encoder instance.

Yes, we'll probably have only one Encoder as we'll have additionally a magnetic position sensor connected into MESA card through SSI.

Yes sorry I misread the ID information the first time

So this may in fact be a hostmot2 driver bug since I dont think there
has ever been a configuration with just one encoder module

As I said adding a second encoder on the P2 I/O connector is harmless
if the pins are just used as GPIO.

I will see if i can duplicate this bug with a 1 encoder setup and if its a real bug, get it fixed

I followed your advice and added a second encoder as you said that only one encoder is too unusual.
But I still see two position pins -- now for each of the two encoders.

Look carefully (I didn't at first), you will see that the names
are truncated, the first pin is:

hm2_5i25.0.encoder.00.position

but the second is

hm2_5i25.0.encoder.00.position-latched

Why your output is truncated I dont know, heres what I got with

halcmd show pin | grep encoder.00.position

25 float OUT 0 hm2_7i76e.0.encoder.00.position
25 float OUT 0 hm2_7i76e.0.encoder.00.position-latched

Yes, you are right.

Got it also with line completion:
Code:
halcmd: getp hm2_5i25.0.encoder.01.position hm2_5i25.0.encoder.01.position hm2_5i25.0.encoder.01.position-latched
