[PATCH v2 0/2] ASoC topology header parsing refinement
This small series is to optimize the header logging during the topology parsing. This is verified work fine on both SOF and SST drivers (bxt_rt298 with dfw_sst.bin).
Change History: v2: - Change the internal used array to be 'static' to fix the issue reported by: kbuild test robot lkp@intel.com - Add testing coverage including Intel SST driver also.
v1: - Initial version.
Keyon Jie (2): ASoC: topology: refine and log the header in the correct pass ASoC: topology: remove the redundant pass checks

The check (tplg->pass == le32_to_cpu(hdr->type)) makes no sense as it is comparing two different enums, refine the element loading functions, and log the information when the header is being parsed in the corresponding parsing pass.

I am also fine with this, though I thought my previous version looks more organized and not so error-prone as we need 8 more assignation here.

Another option, if you want to reduce assignment count, is to keep soc_pass_load while still removing the private map. Said soc_pass_load would require declaration update to accept function ptr on top of what's already there.
In consequence, soc_tplg_load_header becomes a switch-case with a bunch of case X: return soc_pass_load(tplg, hdr, pass=_MY_PASS (e.g. SOC_TPLG_PASS_VENDOR), elem_load=_MY_LOAD_FUNC (e.g. soc_tplg_vendor_load))

I would prefer to use the assignment one, let me update the series now.

As we have check the 'pass' in the soc_elem_pass_load(), so no need to check it again in each specific elem_load function, at the same time, the tplg->pos will be reset to the next header base when the pass is mismatched, so the increasing of the tplg->pos in these cases made no sense. Here remove all of them.

This small series is to optimize the header logging during the topology parsing. This is verified work fine on both SOF and SST drivers (bxt_rt298 with dfw_sst.bin).
Change History: v2:
- Change the internal used array to be 'static' to fix the issue reported by: kbuild test robot lkp@intel.com
- Add testing coverage including Intel SST driver also.
v1:
- Initial version.

No regression after applying these and running through SST CI on cAVS 1.5+ (GLK) and 1.8 (CNL).
Given some comments on 1/2 though, believe it could be simplified.

Can the tests be run on SKL/KBL? That's where the cAVS driver will be used and where this patchset will have an impact. Thanks!

Yes, they were just tested on KBL Chrome book with cAVS driver by Vamshi and Sathya.
