Subject: [PATCH v2 00/13] Use qmp_send to update co-processor load state
Date: Mon,  7 Jun 2021 21:09:19 +0530	[thread overview]
Message-ID: <1623080372-13521-1-git-send-email-sibis@codeaurora.org> (raw)

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence. These co-processors enter
low-power modes independent to that of the application processor and
the load state resources linked to them are expected to remain unaltered
across system suspend/resume cycles. To achieve this behavior let's stop
modeling them as power-domains and replace them with generic qmp_send
interface instead.

Previous dicussion on dropping power-domain support from AOSS QMP driver

Depends on:
qmp_send: https://patchwork.kernel.org/project/linux-arm-msm/cover/1620320818-2206-1-git-send-email-deesin@codeaurora.org/
rproc,adsp_yaml: https://patchwork.kernel.org/project/linux-arm-msm/patch/20210603142639.8335-1-s-anna@ti.com/

V2:
* load_state is currently broken on mainline so be safely dropped
   without side-effects.
 * Rebased on top of qmp_send v3 series.
 * Dropped R-b from Stephen and Rob on patch 3 due to the yaml
   conversion.
 * New patch [12] to drop unused aoss-qmp header.
 * Commit message update [patch 1] [Rob]
 * Reorder the series [Stephen]
