J721S2XSOMXEVM: rpmsg_chrdev driver not working after moving from 6.6 to 6.12 kernel version (missing rpmsg devices under /dev)

Hi Darko,

Darko Alavanja said:

after updating to 6.12 kernel version (I tried various SRCREVs but let's say 6.12.57) there's only /dev/rpmsg_ctrl0 device available, the other ones are missing.

6.12.57 would be the 11.2 SDK, the LTS SDK release from the 11.x Release stream.

IPC is fundamental to enable the complex multi-core usecases on our TDA4 SoCs, and our SDK would be completely broken if this is not working. Our SDKs are fully tested, and I believe this is some integration issues on your custom board/build rather than an issue with the Linux drivers or the SDKs.

Darko Alavanja said:

This is a log of working setup with ti-linux-staging 6.6.58

Your log is limited, and I can see that C71_0 has booted successfully, while the C71_1 has not booted. The logs do recognize that the firmware is booted earlier (IPC-only mode detection), but I do not see any traces associated with the parsing of the rsc_table section.

Linux requires that a resource table be supplied and linked into your firmware image at the appropriate location (expecting at 0xa71000000 based on your traces, also the address used by IPC firmwares in SDKs).

Please provide the output of the following commands:

$ head /sys/kernel/debug/remoteproc/remoteproc*/name

$ head /sys/kernel/debug/remoteproc/remoteproc*/resource_table

Can you also try not booting the DSPs at U-Boot or SBL, and rely on Linux kernel to boot the firmwares? This may give some more traces.

Darko Alavanja said:

The DSP firmware is the same and I also tested it with ipc_echo_test_c7x_1_release_strip.xe71 from ti-rtos-firmware package.

Are you re-using the firmwares built using the older SDK, or did you rebuild the firmwares using the corresponding 11.2 RTOS SDK?

Darko Alavanja said:

Were there any updates with remoteproc/rpmsg framework between the kernel versions and what is additonally needed with 6.12 to communicate with the DSP core over rpmsg?

remoteproc/rpmsg is all upstream code, and the fundamental architecture is still the same.

Hello Suman, thank you for the details.

Here's a minimal test setup I tried to make easy as possible to replicate

meta-ti is checked out at 11.02.13 https://git.yoctoproject.org/meta-ti/tag/?h=11.02.13
I used C7 binaries from ti-ipc-rtos recipe to make sure that my SDK build is not introducing the issue, again with the tag 11.02.13 https://git.ti.com/cgit/processor-firmware/ti-linux-firmware/tag/?h=11.02.13

Then I built an image similar to core-image-minimal, one with 6.6 kernel and the other with 6.12 by setting TI_PREFERRED_BSP variable in my local.conf

Here are the logs with resource tables commands you asked

And also 6.12 doesn't have /dev/rpmsg0 and /dev/rpmsg1 devices created.

It seems that something changed with 6.12 kernel in the way how rpmsg is handled and I don't quite see what exactly.
I'm trying to retest now with rpmsg_char_simple test.

Thank you,

Hi Darko,

Darko Alavanja said:

The absence of traces hint at the rpmsg_ns driver not creating the devices.

Can you provide the output of the following commands?

$ lsmod

$ ls -l /sys/bus/rpmsg/devices

$ ls -l /sys/bus/rpmsg/drivers

$ ls -l /sys/bus/virtio/devices

$ ls -l /sys/bus/virtio/drivers

Darko Alavanja said:

And also 6.12 doesn't have /dev/rpmsg0 and /dev/rpmsg1 devices created.

These are created only when the local endpt devices are created through the character driver that interacts with the rpmsg_ctrl driver. The rpmsg_ctrl devices seems to be created as per your 6.12 log.

Which version of ti-rpmsg-char library are you using? Did you update your filesystem to pick up any library updates between 6.6 and 6.12?

When I switched meta-ti to tag 11.02.13 it got updated to 0.6.10 (SRCREV = "057b1a249261e26d00c501b59646957160ec815b")

The first obvious difference in lsmod is that 6.12 has separate ti_k3_common driver which ti_k3_dsp_remoteproc uses.
6.6 doesn't have ti_k3_common, those functions should be implemented in ti_k3_dsp_remoteproc directly.

I think I can find somewhere some SK or EVM boards to test out the prebuilt images.

Hi Darko,

Yes, but ti_k3_common driver is a non-factor.

Looking at your logs, the virtio device itself for your second DSP is not showing up for whatever reason, but all the virtio and rpmsg drivers are present. Your earlier resource_table traces look to be shortened, and I am unable to see the vring contents from your resource table.

I have run this on my TI J721S2 EVM with the 11.2 SDK, and everything is working properly.

The following log is w/o applying the k3-j721s2-vision-apps.dtbo overlay, and not booting the cores from U-Boot, and disabling the ti_k3_r5f_remoteproc.ko driver to only boot the DSPs. The library version also matches.

Please confirm that you have linked the right C71_1 firmware image, and check the carveout memories for vrings using the following command,

$ cat /sys/kernel/debug/remoteproc/remoteproc1/carveout_memories

Also, ensure that you have a carveout memory for the RTOS-to-RTOS IPC, your earlier snippet log doesn't show all the carveouts.

regards
