[Qemu-devel] [PATCH v5 0/2] spapr-rtas: add ibm, get-vpd RTAS interface

Posted by Maxiwell S. Garcia 5 years, 1 month ago

Here are two patches to add a handler for ibm,get-vpd RTAS calls.
This RTAS exposes host information in case of set QEMU options
'host-serial' and 'host-model' as 'passthrough'.

The patch 1 creates helper functions to get valid 'host-serial'
and 'host-model' parameters, guided by QEMU command line. These
parameters are useful to build the guest device tree and to return
get-vpd RTAS calls. The patch 2 adds the ibm,get-vpd itself.

Hi Maxiwell,

You should probably respin this series because of the following patch,
already in ppc-for-4.0 and in David's latest PR.
