* Regarding SMBus @ 2020-09-09 5:23 gopi ratnakaram 2020-09-09 5:27 ` Greg Gallagher 2020-09-09 8:02 ` Jan Kiszka 0 siblings, 2 replies; 8+ messages in thread From: gopi ratnakaram @ 2020-09-09 5:23 UTC (permalink / raw) To: xenomai 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? --best regards, R Gopi Krishna, Svaya Robotics Pvt., Ltd., Hyderabad, India.

I just tried to remove I2C_I801 driver, re-compile kernel image and it boot fine on my test board. --- a/arch/x86/configs/xenomai_test_defconfig +++ b/arch/x86/configs/xenomai_test_defconfig @@ -2938,9 +2938,9 @@ CONFIG_I2C_ALGOBIT=y # CONFIG_I2C_ALI15X3 is not set # CONFIG_I2C_AMD756 is not set # CONFIG_I2C_AMD8111 is not set -CONFIG_I2C_I801=y +# CONFIG_I2C_I801 is not set # CONFIG_I2C_ISCH is not set -CONFIG_I2C_ISMT=m +# CONFIG_I2C_ISMT is not set # CONFIG_I2C_PIIX4 is not set # CONFIG_I2C_NFORCE2 is not set # CONFIG_I2C_SIS5595 is not set 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. BR fino Sent: Thursday, September 10, 2020 4:41 PM 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? --best regards, R Gopi Krishna, Svaya Robotics Pvt., Ltd., Hyderabad, India.

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.
