Revision dc280d93623927570da279e99393879dbbab39e7 authored by Thomas Gleixner on 21 December 2016, 19:19:49 UTC, committed by Thomas Gleixner on 25 December 2016, 09:47:42 UTC
Developers manage to overwrite states blindly without thought. That's fatal and hard to debug. Add sanity checks to make it fail. This requries to restructure the code so that the dynamic state allocation happens in the same lock protected section as the actual store. Otherwise the previous assignment of 'Reserved' to the name field would trigger the overwrite check.

Say y here to support OMAP's remote processors (dual M3
and DSP on OMAP4) via the remote processor framework.
Currently only supported on OMAP4.
Usually you want to say y here, in order to enable multimedia
use-cases to run on your platform (multimedia codecs are
offloaded to remote DSP processors using this framework).
It's safe to say n here if you're not interested in multimedia
offloading or just want a bare minimum kernel.

Say y here to support Wakeup M3 remote processor on TI AM33xx
and AM43xx family of SoCs.
Required for Suspend-to-RAM on AM33xx and AM43xx SoCs. Also needed
for deep CPUIdle states on AM33xx SoCs. Allows for loading of the
firmware onto these remote processors.
If unsure say N.

Say y here to support DA8xx/OMAP-L13x remote processors via the
remote processor framework.
You want to say y here in order to enable AMP
use-cases to run on your platform (multimedia codecs are
offloaded to remote DSP processors using this framework).
This module controls the name of the firmware file that gets
loaded on the DSP. This file must reside in the /lib/firmware
directory. It can be specified via the module parameter
da8xx_fw_name=<filename>, and if not specified will default to
"rproc-dsp-fw".
It's safe to say n here if you're not interested in multimedia
offloading.
