Subject: [PATCH RFC v3 0/7] soc: qcom: add in-kernel pd-mapper implementation
Date: Mon, 04 Mar 2024 19:03:30 +0200 [thread overview]
Message-ID: <20240304-qcom-pd-mapper-v3-0-6858fa1ac1c8@linaro.org> (raw)
Protection domain mapper is a QMI service providing mapping between
'protection domains' and services supported / allowed in these domains.
For example such mapping is required for loading of the WiFi firmware or
for properly starting up the UCSI / altmode / battery manager support.
The existing userspace implementation has several issue. It doesn't play
well with CONFIG_EXTRA_FIRMWARE, it doesn't reread the JSON files if the
firmware location is changed (or if the firmware was not available at
the time pd-mapper was started but the corresponding directory is
mounted later), etc.
However this configuration is largely static and common between
different platforms. Provide in-kernel service implementing static
per-platform data.
NOTE: this is an RFC / RFT, the domain mapping data might be inaccurate
(especially for SM6xxx and SC7xxx platforms), which is reflected by
several TODO and FIXME comments in the code.

Changes in RFC v3:
- Send start / stop notifications when PD-mapper domain list is changed
- Reworked the way PD-mapper treats protection domains, register all of
them in a single batch
- Added SC7180 domains configuration based on TCL Book 14 GO
- Link to v2: https://lore.kernel.org/r/20240301-qcom-pd-mapper-v2-0-5d12a081d9d1@linaro.org
Changes in RFC v2:
- Swapped num_domains / domains (Konrad)
- Fixed an issue with battery not working on sc8280xp
- Added missing configuration for QCS404
