Team,
I am working with xenomai patched with kernel 4.19.59 on an Industrial
motherboard which has an SMBus. After patching during my testing it was
observed that the SMbus got some issues and the bus is locking immediately
after running my application and the error log is as follows. But, when I
run my SMbus based application in the kernel 4.15.0 without RT patching it
was working fine. Is there any configuration setting while patching xenomai
is causing this issue?

The Linux interrupt is not making it through. Is it shared with another
device that happens to be managed by an RTDM driver? Does the issue
disappear when keeping the kernel version, just turning of Xenomai and
I-pipe in the kernel configuration?

Yes, the motherboard manufacturer has shared the bus with other devices
too. I didn't change any kernel configuration with respect to xenomai, but
the issue was not there in 4.15.0 which is not RT patched where I am not
getting this kind of issue. But, this only happened in 4.19.59 xenomai
patched kernel. Is there any interrupt related configuration change in
kernel configuration can resolve this issue, please let me know.

If u are using this kernel, a quick try is use acrn_defconfig instead of xenomai_test_defconfig.
It is the defconfig using by ACRN team:
https://github.com/intel/linux-stable-xenomai/blob/F/4.19.59/base/ipipe/xenomai_3.1/arch/x86/configs/acrn_defconfig
xenomai_test_defconfig was originally from Yocto, not optimized for PC.
We are struggling for a good way to make proper defconfig,
but it's really hard work due to kernel config are more than 8000 lines already.

Hi Fino,
Firstly, I would like to confirm that 4.19.59 without RT patching I am not
finding any issue with SMBus locking as I have tested it just some time
back.
As per your inputs I have few queries,
If u are using this kernel, a quick try is use acrn_defconfig instead of
xenomai_test_defconfig.
It is the defconfig using by ACRN team:
https://github.com/intel/linux-stable-xenomai/blob/F/4.19.59/base/ipipe/xenomai_3.1/arch/x86/configs/acrn_defconfig
*Question: Do I need to change configure file and reinstall again? Please
provide me with any supporting documents available?*

Hi gopi,
It will take time to root cause such a issue, let’s find a WA first then don’t block your project.
I just tried to remove I2C_I801 driver, re-compile kernel image and it boot fine on my test board.

Usually, SMBus(similar with I2C) on a x86_64 UEFI PC mainboard only connect to DDR’s DIMM,
BIOS use to read DDR’s config (size, topology… ); after OS boot, kernel don’t need read it since
DDR memory already finished init.
If this method don’t work, then we need find out other way.

Hi Fino,
Firstly, I would like to confirm that 4.19.59 without RT patching I am not finding any issue with SMBus locking as I have tested it just some time back.
As per your inputs I have few queries,
If u are using this kernel, a quick try is use acrn_defconfig instead of xenomai_test_defconfig.
It is the defconfig using by ACRN team:
https://github.com/intel/linux-stable-xenomai/blob/F/4.19.59/base/ipipe/xenomai_3.1/arch/x86/configs/acrn_defconfig
Question: Do I need to change configure file and reinstall again? Please provide me with any supporting documents available?

If u are using this kernel, a quick try is use acrn_defconfig instead of xenomai_test_defconfig.
It is the defconfig using by ACRN team:
https://github.com/intel/linux-stable-xenomai/blob/F/4.19.59/base/ipipe/xenomai_3.1/arch/x86/configs/acrn_defconfig
xenomai_test_defconfig was originally from Yocto, not optimized for PC.
We are struggling for a good way to make proper defconfig,
but it's really hard work due to kernel config are more than 8000 lines already.
