Subject: [PATCH v6 0/8] drm: cec: convert DRM drivers to the new notifier API
Date: Tue, 13 Aug 2019 13:02:32 +0200 [thread overview]
Message-ID: <20190813110300.83025-1-darekm@google.com> (raw)
This series updates DRM drivers to use new CEC notifier API.
Only first two patches were tested on the actual hardware.
Changes since v5:
Fixed a warning about a missing comment for a new member of
drm_dp_aux_cec struct. Sending to a wider audience, including
maintainers of respective drivers.
Changes since v4:
Addressing review comments.
Changes since v3:
Updated adapter flags in dw-hdmi-cec.
Changes since v2:
Include all DRM patches from "cec: improve notifier support,
add connector info connector info" series.
Changes since v1:
Those patches delay creation of notifiers until respective
connectors are constructed. It seems that those patches, for a
couple of drivers, by adding the delay, introduce a race between
notifiers' creation and the IRQs handling threads - at least I
don't see anything obvious in there that would explicitly forbid
such races to occur. v2 adds a write barrier to make sure IRQ
threads see the notifier once it is created (replacing the
WRITE_ONCE I put in v1). The best thing to do here, I believe,
would be not to have any synchronization and make sure that an IRQ
only gets enabled after the notifier is created.
