PCIe - No parport registered at "0x " . This is not Always an error.Continuing. was created by RobotMatic
I installed a PCIe board on debian 12 linuxcnc 2.9.4 and even though it works perfectly I get this error at the start of linuxcnc.
Is there a way to delete the message?
thanks

What does lspci say?
Perhaps try a different number.
There is often like 3 hexadecimal codes for one card.
Try all three, maybe one will work.

Had the same issue yesterday, PCI-E Sunix card, works perfectly but the error shows up whenever LinuxCNC is started.
Did not bother with it, but i did notice LSPCI does not show loaded module for it at all, but it does show all the other info with addresses and stuff.

As the message says it's not really an error, I think the only way to stop the message would be to modify the hal_parport code, or I not sure if this would work but add a debug level when loading the driver. First would work but means compiling Linuxcnc one's self the second option is just a guess.
If the machine works I wouldn't bother too much about it. Yeah it is a little annoying. But then again you have the convenience of CNC

The non-native parallel port is a parallelized serial port. The Linux kernel takes it as a serial PCIE port. That's where linuxcnc comes into conflict and raises the alarm. The older parallel port PCI expansion boards were neater and sent the OS the message (I'm a parallel port). This Generation does not, that is why this alarm appears that tells us (continue, it may not be a mistake). The issue is that linuxcnc starts in a messy way and I would like to solve it.

Yeah, this deserves a log file entry for debugging, but not an error pop-up...

So far i would think this is hardware related or blacklisted, the same card i removed from another PC that does not complain about it.
The warning PC had a PCI to parallel card and up to yesterday was working fine, for years, two days ago it was shut down as usual and yesterday morning it could not find the PCI card although LSPCI show it and the addresses and everything, but does not show kernel module nor kernel driver in use.
I have a stinking suspicion the card is being blacklisted, but i had no time to check as it was 11:30PM and the client was waiting for it (with his friends) and they are some 90KM far.
Nor did i try to modprobe, i could have done that, cr@p, but i forgot as i was poised at fixing it promptly.

The chips used in these cards are multi function,some of them can be strapped to work as SPI ports. Or they can be configured for a combination of serial only or serial & parallel ports. The kernel does not take the board as a serial PCIE port. Whilst some do load the parport_serial driver that does not mean it is seen a just a serial PCIE port.
I have a multifunction card installed that uses the parport_serial drive
As you can see it is recogonised as a parallel port at 0x3000.
Now for the serial part of the card, there is also an on board serial port at the "regular address"
As you can see it is recogonised as a serail port at 0x3008.
The device doesn't say "I'm a parallel port" the kernel loads the driver depending on the devices PCIID
As you can see the this is the list of ID it is loaded for.
The message comes from /src/rtapi/uspace_rtapi_parport.cc

I'd probably just change:

"This is not always an error. Continuing.\n", base);
to
rtapi_print_msg(RTAPI_MSG_WARN, "No parport registered at 0x%x. "

I have a Sunix PCIe Parallel port card that works with no error message.
lspci -v shows the kernel module as "parport" and displays 4 Hexadecimal port IDs, but only 1 works without error.

Weird.Had the same issue yesterday, PCI-E Sunix card, works perfectly but the error shows up whenever LinuxCNC is started.
Did not bother with it, but i did notice LSPCI does not show loaded module for it at all, but it does show all the other info with addresses and stuff.
