Intermittent "bcm2835_mmal_vchiq: Failed to open VCHI service connection (status=-1)" on boot (5.10).

[bhjelstrom]

Describe the bug

Using 5.10 and associated firmware, the following error occurs during some boots. When the error occurs, the 5647 camera module is unusable.

The frequency of the error appeared to increase as I optimized boot time by disabling EDID reads, disabling kernel tracing, etc.

Below are logs from two different 5.10 kernel versions (each with correct firmware versions). It looked like the camera subsystem was getting a lot of attention, so I checked 5.10.90 and the 318e3373496 firmware (Jan 13), but the issue persisted.

To reproduce Boot a CM3 with an OV5647 attached. Use 5.10.36 or 5.10.90 kernel with associated rpi extended firmware. The failure does not always occur - on 5.10.90 I had 20 successful boots followed by a boot with the above error.

Expected behaviour The error never occurs, and the camera is always available for streaming. This error does not occur at all (with hundreds of tested boots) on 4.19.120

Actual behaviour The error shown in the kernel output above occurs, and the camera is unavailable. From my testing, it appears as though a different critical issue I'm facing is fixed in 5.10 (https://github.com/raspberrypi/linux/issues/3702), but I cannot upgrade until the camera subsystem is reliable.

System CM3+ GPU_MEM 256MB ENC28J60 is the only other peripheral device

[pelwell]

Those two logs are identical, which is almost impossible - did you paste the same one twice?

I fixed the previous post. Here is more output from a recent reproduction of the issue (vcdbg, dmesg, journalctl). Interestingly, the vcdbg output shows that the camera was found, but we still see "bcm2835_mmal_vchiq: Failed to open VCHI service connection (status=-1)"

config:

start_file=start_x.elf
fixup_file=fixup_x.dat
boot_delay=1
kernel=zImage
gpu_mem=128
hdmi_ignore_hotplug=1
hdmi_ignore_edid=0xa5000080
dtoverlay=miniuart-bt
disable_splash=1
dtparam=spi=on
dtoverlay=enc28j60
dtoverlay=pi3-disable-bt
enable_uart=1
dtoverlay=dwc2,dr_mode=host

The issue continues to occur (intermittently, roughly once per 20-30 boots) after increasing CMA size to 256MB from 64MB

The logging doesn't give any clues as to what is going wrong - the firmware log is showing that the underlying connection is established with the ARMs (equivalent to plugging in the network cable), but nothing else. Unfortunately the failure happens too early for you to be able to make the logging more verbose, but I've just pushed a patch to the rpi-5.15.y kernel source branch that adds module parameters to control them. Sometime in the next few days that will appear in a release that you will be able to install with sudo rpi-update. Once you've done that, adding vchiq.arm_log_level=6 to cmdline.txt will give you kernel log entries like this:

pi@raspberrypi:~$ dmesg | grep vchiq:

Adding vchiq.core_msg_log_level=6 will show more details of the traffic - this is what you get running raspistill -o cam.jpg with no camera attached:

That's not something you would want to leave enabled in normal use, but if you keep rebooting until you get a failure then capture the output of dmesg | grep vchiq: it should answer a lot of questions.

I appreciate this @pelwell. I patched my 5.15.32 with your change since 5.15.36 breaks my cm3+ ethernet.

[pelwell]

I'm just going through it now - the first connection works, but in the failure case the second and third are clearly refused by the firmware. That's given me something concrete to look at.

[pelwell]

Annoyingly it's not wanting to fail at the moment, but I've left it sitting in a reboot loop looking for the error message.

I should probably mention that the legacy camera stack is no longer being worked on or maintained (hence the "legacy"), so unless something obvious appears this may not get fixed.

[bhjelstrom]

Your experience made me think that this had something to do with our camera application. I delayed our camera application for one minute and confirmed that it is not causing the issue. I would love to transition to libcamera, but I'm experiencing some difficulties: https://forums.raspberrypi.com/viewtopic.php?t=333753#p1998390

[bhjelstrom]

Another data point - this occurs on 5.10.20 as well.

[pelwell]

The "reboot if no error" loop has run for almost 6000 iterations without a MMAL/VCHIQ failure.. The whole thing feels like a race condition, but without a means to reproduce it making progress is impossible.

Is there a shorter start-up delay that still avoids the problem and is acceptable as a workaround?
