There are several 'if' conditions of the form: if (!!(module_ens & SOME_FLAG)) Those can be replaced with: if (module_ens & SOME_FLAG) Signed-off-by:

The params and stats entities have a field 'is_streaming'. This field is not needed since the entities can have available buffers only if they stream and therefore it is enough to check if there are buffers available. As a result, their start_stream callbacks can be removed since they only set the 'is_streaming' field. Signed-off-by:

The buffer lists of stats and params entities are initialized in queue_setup callback with 'INIT_LIST_HEAD'. It is enough to initialize the lists only upon registration. For the stats entity the list is already initialize upon registration. Signed-off-by:

Currently the code uses 'list_cut_position' to move the buffers to a temporary list. Replace it with 'list_splice_init'. This is nicer since we don't need to access params.prev. Also, replace INIT_LIST_HEAD with the simpler LIST_HEAD. Signed-off-by:

In function rkisp1_vb2_start_streaming, the call to media_pipeline_start should be the first thing in order to validate the links and prevents their state from being modified before power up and streaming. Adjust stop streaming to the same logic, call media_pipeline_stop after we disable streaming on the entities in the topology. Signed-off-by:

The vivid driver is a bit flaky w.r.t. the kthread timing, esp. when running inside a virtual machine. This is caused by calling schedule_timeout_uninterruptible(1) which can actually take more than one jiffie. A while loop with schedule() turns out to be a lot more precise. Also, if mutex_trylock() fails, then just call schedule() instead of schedule_timeout_uninterruptible(1). There is no need to wait until the next jiffer, just schedule(), then try to get the lock again. This is still not precise enough, it is still relatively easy to get missed frames. This really should be converted to use a proper timer, but for now this solves the worst problems. Signed-off-by:

The description of the V4L2_COLORSPACE_470_SYSTEM_BG stated that it was superseded by SMPTE 170M. That is incorrect. The probably root cause of this is that the HDMI standard does not support this colorspace and, unless otherwise signaled, will fall back to SMPTE 170M for SDTV. However, EBU Tech. 3321 states that sources should signal Rec. 709 as the colorimetry when using HDMI since the difference between Rec. 709 and Tech. 3213 are negligible. Update the text accordingly. Also drop a spurious " at the end of the Tech 3213 title in the bibliography. Signed-off-by:

There are no remaining conversions in v4l2_compat_ioctl32(), so all the infrastructure for it can be removed, with the only remaining bit being the compat_ioctl32() callback into drivers that implement their own incompatible data structures. Signed-off-by:

There are eight remaining ioctl commands handled by copying incompatible data structures in v4l2_compat_ioctl32(), all of them fairly simple. Change them to instead go through the native ioctl infrastructure and only special-case the data copy. Signed-off-by:

Now that the 'clips' array is accessed by common code in the native ioctl handler, the same can be done for the compat version, greatly simplifying the compat code for these four ioctl commands. [hverkuil: fix: CHECK: Alignment should match open parenthesis] Signed-off-by:
-
Arnd Bergmann authored
The v4l2_format based ioctls can have an indirect pointer to an array of v4l2_clip structures for overlay mode, depending on the 'type' member. There are only five drivers that use the overlay mode and copy the data through the __user pointer. Change the five drivers to use memcpy() instead, and copy the data in common code using the check_array_args() helpers. This allows for a subsequent patch that use the same mechanism for compat ioctl handlers. Note that there is another pointer for a 'bitmap' that is only used in the 'vivid' driver and nowhere else. There is no easy way to use the same trick without adding complexity to the common code, so this remains a __user pointer.

Arnd Bergmann authored
The ioctl commands based on v4l2_buffer have two sets of compat calls, one for native time32 structures, and one for compat structures on 64-bit architectures. Change the compat version to use the same approach as the other simpler one, for both versions of the structure. In an earlier version of the patch, I unified the v4l2_buffer_time32 and v4l2_buffer32_time32 compatibility handling into a single implementation, but that relied on having it all in one file, rather than having the in_compat_syscall() version in v4l2-compat-ioctl32.c.

The v4l2_ext_controls ioctl handlers use an indirect pointer to an incompatible data structure, making the conversion particularly tricky. Moving the compat implementation to use the new v4l2_compat_get_user()/v4l2_compat_put_user() helpers makes it noticeably simpler. In v4l2_compat_get_array_args()/v4l2_compat_put_array_args(), the 'file' argument needs to get passed to determine the exact format, which is a bit unfortunate, as no other conversion needs these.

These seven commands are all compatible and do not need any conversion handlers. The existing ones just copy 32-bit integers around, and those are always compatible. Signed-off-by:
-
Arnd Bergmann authored
The v4l2-compat-ioctl32() currently takes an extra round trip through user space pointers when converting the data structure formats. In particular, this involves using the compat_alloc_user_space() and copy_in_user() helpers that often lead to worse compat handlers compared to using in_compat_syscall() checks when copying the data. The native implementation already gained a simpler method to deal with the conversion for the time32 conversion. Hook into the same places to provide a location for reading and writing user space data from inside of the generic video_usercopy() helper. Hans Verkuil rewrote the video_get_user() function here to simplify the zeroing of the extra input fields and fixed a couple of bugs in the original implementation.
