Subject: [PATCH v3 0/5] ASoC / rpmsg / remoteproc / soc: qcom: Constify buffer passed to send functions
Date: Tue, 17 Mar 2026 13:36:49 +0100 [thread overview]
Message-ID: <20260317-rpmsg-send-const-v3-0-4d7fd27f037f@oss.qualcomm.com> (raw)
This got acks from Mathieu (remoteproc) and Mark (audio), so can we
funnel everything via Qualcomm remoteproc tree?
Dependencies / merging
======================
Entire patchset is one logical chain, all further patches depend on
previous ones, thus everything should be taken via same tree or shared
between trees with tags. Probably everything should go via ASoC with
necessary acks.
Changes in v3:
- Subject fixes (Angelo)
- Tags
- Link to v2: https://patch.msgid.link/20260310-rpmsg-send-const-v2-0-0e94c5db9bf4@oss.qualcomm.com
Changes in v2:
- New patch #5: media: platform: mtk-mdp3: Constify buffer passed to mdp_vpu_sendmsg()
- Rebase, add acks.
- Link to v1: https://patch.msgid.link/20251130-rpmsg-send-const-v1-0-cb11c7e0a024@oss.qualcomm.com
Description
===========
The remoteproc and rpmsg send-like functions should not modify data
being sent, so buffer should be marked as pointer to const. This is not
only self-documenting code but actually increases the actual safety and
clearly documents who is the owner of passed buffer.
Best regards,
Krzysztof
