I have applied your patch to my local branch - it will be published on Monday
with the release of the v5.9-rc1 kernel.

Thanks for your patch.
I would like to test HiSilicon ETM device feature on
Kunpeng 920 based server.
I applied the patch and booted the kernel with the changes.
However I don't see any device files neither here:
/sys/bus/coresight/devices/
nor here:
/sys/bus/event_source/devices/cs_etm/sinks/
What should a user expect new in os with this patch added?
Thanks,
Alexei

Thanks for your test :)
Kunpeng 920 platform(Non-PG) support tracing CPU instruction, source
device is coresight ETM, link device is coresight funnel and sink device
is ultrasoc SMB. So you need to insmod coresight-* driver and SMB
driver, which patch is :
Add support for UltraSoc System Memory Buffer
https://lore.kernel.org/linux-arm-kernel/20220416083953.52610-1-liuqi115@huawei.com/
by the way, can you help to check /sys/bus/amba/devices/, and make sure
that the firmware of your board has supported ETM, funnel and SMB devices?

Here we go:

/home/huawei
huawei@armubuntu:~$ ls /sys/bus/amba/devices/
huawei@armubuntu:~$
Look like our server firmware should be upgraded, right?
Your help and support is greatly appreciated.

I would appreciate if you could share some links to upgrade bits and docs, if possible,
so we could use it to perform the upgrade.

Does your system use ACPI based firmware ? If that is
the case, we do not have the support for ETM with system instructions
at the moment. Anshuman is currently working on addressing
this.
