Query on intel PECI subsytem driver being removed #212

Closed hemanthkumarm-ami closed 2 years ago

hemanthkumarm-ami commented 2 years ago

can i know the reason why intel PECI subsytem is removed after kernel dev5.8 ? is there any plan to support this in future releases.

The PECI patches had been living in the OpenBMC kernel tree (and not in the mainline kernel) for a long time and the efforts to get them merged upstream seemed to have stalled, so they were removed from the OpenBMC kernel (see OpenBMC kernel docs and Joel's email).

However, there's recently been some renewed activity on that front (see https://lore.kernel.org/openbmc/20211115182552.3830849-1-iwona.winiarska@intel.com/T/#t), so hopefully we'll see a PECI subsystem merged in the mainline kernel (and OpenBMC's as well) in the not-too-distant future (though note that the new version is behaviorally a bit different than the old one and hence the OpenBMC userspace may require some adaptation to make use of it).

Thanks for summarising Zev. We would like to see Intel support their hardware in the mainline tree.

Please take any follow up discussion to the mailing list.
