[RFC 00/16] Make use of kref in media device, grab references as needed

Hi folks, I've been working on this for some time now but only got the full patchset working some moments ago. The patchset properly, I believe, fixes the issue of removing a device whilst streaming. Media device is refcounted and its memory is only released once the last reference is gone:

[RFC 06/16] media: Dynamically allocate the media device

From: Sakari Ailus Allow allocating the media device dynamically. As the struct media_device embeds struct media_devnode, the lifetime of that object is that same than that of the media_device. Signed-off-by: Sakari Ailus ---

[RFC 12/16] media: Shuffle functions around

As the call paths of the functions in question will change, move them around in anticipation of that. No other changes. Signed-off-by: Sakari Ailus --- drivers/media/media-device.c | 90 ++-- 1 file changed, 45 insertions(+),

[RFC 10/16] media: Document media device allocation API

Document the addition of the media_device_alloc() function to allocate a media device. Also, document how reference counting and releasing a media device works. Deprecate API elements which are no longer needed with dynamically allocated media devices. Signed-off-by: Sakari Ailus

[RFC 07/16] media-device: struct media_device requires struct device

The media device always has a device around. Require one as an argument for media_device_alloc(). Signed-off-by: Sakari Ailus --- drivers/media/media-device.c | 13 +++-- include/media/media-device.h | 4 +++- 2 files changed, 14 insertions(+), 3

[RFC 16/16] omap3isp: Don't rely on devm for memory resource management

devm functions are fine for managing resources that are directly related to the device at hand and that have no other dependencies. However, a process holding a file handle to a device created by a driver for a device may result in the file handle left behind after the device is long gone. This

[RFC 13/16] media-device: Postpone graph object removal until free

The media device itself will be unregistered based on it being unbound and driver's remove callback being called. The graph objects themselves may still be in use; rely on the kref release callback to release them. Signed-off-by: Sakari Ailus ---

[RFC 03/16] Revert "[media] media-device: dynamically allocate struct media_devnode"

This reverts commit a087ce704b80 ("[media] media-device: dynamically allocate struct media_devnode"). The commit was part of an original patchset to avoid crashes when an unregistering device is in use. Signed-off-by: Sakari Ailus --- drivers/media/media-device.c

[RFC 01/16] Revert "[media] media: fix media devnode ioctl/syscall and unregister race"

This reverts commit 6f0dd24a084a ("[media] media: fix media devnode ioctl/syscall and unregister race"). The commit was part of an original patchset to avoid crashes when an unregistering device is in use. Signed-off-by: Sakari Ailus ---

[RFC 08/16] media: Provide a way to the driver to set a private pointer

Now that the media device can be allocated dynamically, drivers have no longer a way to conveniently obtain the driver private data structure. Provide one again in the form of a private pointer passed to the media_device_alloc() function. Signed-off-by: Sakari Ailus

[RFC 11/16] v4l: Acquire a reference to the media device for every video device

The video device depends on the existence of its media device --- if there is one. Acquire a reference to it. Signed-off-by: Sakari Ailus --- drivers/media/v4l2-core/v4l2-dev.c | 9 - 1 file changed, 8 insertions(+), 1 deletion(-) diff --git

[RFC 15/16] omap3isp: Release the isp device struct by media device callback

Use the media device release callback to release the isp device's data structure. This approach has the benefit of not releasing memory which may still be accessed through open file handles whilst the isp driver is being unbound. Signed-off-by: Sakari Ailus ---

[RFC 09/16] media: Add release callback for media device

The release callback may be used by the driver to signal the release of the media device. This makes it possible to embed a driver private struct to the same memory allocation. Signed-off-by: Sakari Ailus --- drivers/media/media-device.c | 11 ++-

Re: [PATCH 2/4] cxd2841er: provide signal strength for DVB-C

Hi Mauro, Here is a mistake. Instead of 'cxd2841er_read_agc_gain_t_t2' should 'cxd2841er_read_agc_gain_c' be used for SYS_DVBC_ANNEX_ case. and should we use all DVB-C variants ( case SYS_DVBC_ANNEX_A, case SYS_DVBC_ANNEX_B, case SYS_DVBC_ANNEX_C ) here ? 2016-07-01 10:03 GMT-04:00 Mauro
