If the issue is MHI host not getting SBL EE change event on primary event ring then, is it possible that there is some issue with FW image being flashed ? It is possible for you to enable dev_dbg logs to show up in dmesg for MHI core when you reproduce this issue? You can share the entire dmesg log with that. Are you observing this issue after moving to 5.13.6? Do you know if the same FW worked on this device on any other kernel ver before? > > Best regards, > Thomas > Thanks, Hemant -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project ^ permalink raw reply [flat|nested] 11+ messages in thread

I started discussions with the vendor support to clarify this point, as I have also obtained the following trace, which I have not been able to reproduce: [ 51.462714] mhi-pci-generic 0000:01:00.0: firmware crashed (7) [ 51.468881] mhi-pci-generic 0000:01:00.0: firmware crashed (6) [ 51.475059] mhi mhi0: Failed to transition from PM state: DISABLE to: SYS ERROR Process [ 51.486582] mhi-pci-generic 0000:01:00.0: reset [ 53.123953] mhi mhi0: Requested to power ON When this issue occurs, my target is rebooting. > It is possible for you to enable dev_dbg logs to show up > in dmesg for MHI core when you reproduce this issue?

I don’t know, I will ask the question to the vendor support, but I think the answer will be that it was not tested with my mainline driver.

I think maybe about some PCIe suspend/resume issues, could you try disabling runtime-pm for that device? or simply comment `pm_runtime_allow` call?

just increase the timeout to 30 or 60 seconds to be sure. You could also monitor changes in debugfs which can tell you what the registers read and get states at an interval of every second if you'd like. watch -n 1 cat /sys/kernel/debug/mhi/mhi0/states watch -n 1 cat /sys/kernel/debug/mhi/mhi0/regdump You could start this after you load the kernel module to get most out of the debug rather than building as Y, just build as M as Loic suggested.
