Subject: [PATCH v2 0/8] iio: core: wrap IIO device into an iio_dev_opaque object
Date: Thu, 14 May 2020 16:17:02 +0300 [thread overview]
Message-ID: <20200514131710.84201-1-alexandru.ardelean@analog.com> (raw)
This change starts to hide some internal fields of the IIO device into
the framework.
Because the iio_priv_to_dev() will be hidden some pre-work is done to
try to remove it from some interrupt handlers.
iio_priv_to_dev() will become a function call and won't be expandable
into place (as-is now as an inline function).
Changelog v1 -> v2:
- add pre-work patches that remove some calls to iio_priv_to_dev() from
interrupt handlers
- renamed iio_dev_priv -> iio_dev_opaque
- moved the iio_dev_opaque to 'include/linux/iio/iio-opaque.h' this way
it should be usable for debugging
- the iio_priv() call, is still an inline function that returns an
'indio_dev->priv' reference; this field is added to 'struct iio_dev';
the reference is computed in iio_device_alloc() and should be
cacheline aligned
- the to_iio_dev_opaque() container is in the
'include/linux/iio/iio-opaque.h' header; it's still implemented with
some pointer arithmetic; one idea was to do it via an
'indio_dev->opaque' field; that may still be an optionif there are
some opinions in that direction
