Subject: Re: [PATCH v7 12/23] firmware: arm_scmi: Add support for boot-on Telemetry

Message-ID: <027AD7B7-EC61-4A08-A3FF-2192F592C342@contoso.com> (raw)

Hi Cristian,

One error-handling issue inline.

> 	for (int i = 0; i < ti->info.base.num_groups; i++)
> 		scmi_telemetry_group_config_lookup(ti,
> 						   &rinfo->grps[i]);
>
> 	rinfo->num_groups = ti->info.base.num_groups;
>
> 	return 0;

The return value from every group configuration lookup is discarded.

If firmware rejects one lookup or returns a transport error, that group is
still exposed with zero/default cached state, rinfo->num_groups includes
it, and enumeration is reported as successful.

Please propagate the first error, or explicitly mark individual group
state as unavailable while preserving the partial-enumeration status.

Thanks,
Fayçal
