Error: Unexpected realtime delay on task 0 + Watchdog has bit!

Hi guys
I have Orange Pi 5 plus and I've connected it to my Spartan 6 FPGA dev board via SPI.
I used hm2_spi component.
After running some tests I could get 1 MHz output from stepgen.
But every time that I run the LinuxCNC I get this error:
"Unexpected realtime delay on task 0 with period 1000000. This message will only display once per session. Run the latency test and resolve before continuing."
Another error which completely stop the motor is about watchdog:
"hm2/hm2_7i90.0: Watchdog has bit! (set the .has-bit pin to false to resume)"
How can I solve these errors? 
I've read the related posts in forum about these but I couldn't figure it out.

P.S:
The result of latency test after an hour: 14.7 us
The result of command "uname -a":
Linux orangepi5-plus 5.10.160-rt89+ #8 SMP PREEMPT_RT Sun Apr 14 23:02:59 CST 2024 aarch64 GNU/Linux
The exact error is attached
The ini and hal files are attached too.

It may be that the Orange Pi SPI driver is not capable of real time operation.

Printing the tmax values for all functions may help diagnosis:

halcmd show param *.tmax

(these times will be in ns on the Orange Pi)

opi5p@orangepi5-plus:~$ halcmd show param *.tmax

39 s32  RW  583                pid.z.do-pid-calcs.tmax
30 s32  RW  4029890        servo-thread.tmax

This is the result of "halcmd show param *.tmax" command. is it mean that my spi doesn't support realtime? or I can make it better by manipulating the os kernel?

Hey guys
I still have problem. With lots of searching and trying out and talking with some of friends, I think it might be the SPI that have the realtime issue not the os kernel. Please help me to get through this.
I'm still getting these 2 errors:
"Unexpected realtime delay on task 0 with period 1000000. This message will only display once per session. Run the latency test and resolve before continuing."
"hm2/hm2_7i90.0: Watchdog has bit! (set the .has-bit pin to false to resume)"
The watchdog error doesnt show up in a regular timing. but  in every session it will definitely happen.
 

36 s32  RW  3890184        hm2_7i90.0.write.tmax

Means the SPI write to the FPGA took almost 4 ms.
As I mentioned before, this likely means that the
Orange PI's kernel SPI driver is not capable of
real time operation.

So what do you suggest?
I need to use another spi low-level driver?
