[Qemu-devel] [PULL 32/48] ipmi: introduce an ipmi_bmc_sdr_find() API


From: David Gibson
Subject: [Qemu-devel] [PULL 32/48] ipmi: introduce an ipmi_bmc_sdr_find() API
Date: Wed, 26 Apr 2017 17:00:18 +1000

From: Cédric Le Goater <address@hidden>

This patch exposes a new IPMI routine to query a sdr entry from the
sdr table maintained by the IPMI BMC simulator. The API is very
similar to the internal sdr_find_entry() routine and should be used
the same way to query one or all sdrs.

A typical use would be to loop on the sdrs to build nodes of a device
tree.
