* media: v4l2-rect.h: fix v4l2_rect_map_inside() top/left adjustmentsHelen Koike2020-01-081-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | boundary->width and boundary->height are sizes relative to boundary->left and boundary->top coordinates, but they were not being taken into consideration to adjust r->left and r->top, leading to the following error: Consider the follow as initial values for boundary and r: struct v4l2_rect boundary = { .left = 100, .top = 100, .width = 800, .height = 600, } struct v4l2_rect r = { .left = 0, .top = 0, .width = 1920, .height = 960, } calling v4l2_rect_map_inside(&r, &boundary) was modifying r to: r = { .left = 0, .top = 0, .width = 800, .height = 600, } Which is wrongly outside the boundary rectangle, because: v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600 ... if (r->left + r->width > boundary->width) // true r->left = boundary->width - r->width; // r->left = 800 - 800 if (r->top + r->height > boundary->height) // true r->top = boundary->height - r->height; // r->height = 600 - 600 Fix this by considering top/left coordinates from boundary.

* media: v4l2-core: fix v4l2_buffer handling for time64 ABIArnd Bergmann2020-01-031-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | The v4l2_buffer structure contains a 'struct timeval' member that is defined by the user space C library, creating an ABI incompatibility when that gets updated to a 64-bit time_t. As in v4l2_event, handle this with a special case in video_put_user() and video_get_user() to replace the memcpy there. Since the structure also contains a pointer, there are now two native versions (on 32-bit systems) as well as two compat versions (on 64-bit systems), which unfortunately complicates the compat handler quite a bit. Duplicating the existing handlers for the new types is a safe conversion for now, but unfortunately this may turn into a maintenance burden later. A larger-scale rework of the compat code might be a better alternative, but is out of scope of the y2038 work. Sparc64 needs a special case because of their special suseconds_t definition.

* media: v4l2-core: fix VIDIOC_DQEVENT for time64 ABIArnd Bergmann2020-01-031-0/+25
| | | | | | | | | | | | | | | | | | | | The v4l2_event structure contains a 'struct timespec' member that is defined by the user space C library, creating an ABI incompatibility when that gets updated to a 64-bit time_t. While passing a 32-bit time_t here would be sufficient for CLOCK_MONOTONIC timestamps, simply redefining the structure to use the kernel's __kernel_old_timespec would not work for any library that uses a copy of the linux/videodev2.h header file rather than including the copy from the latest kernel headers. This means the kernel has to be changed to handle both versions of the structure layout on a 32-bit architecture. The easiest way to do this is during the copy from/to user space.

* media: v4l2: abstract timeval handling in v4l2_bufferArnd Bergmann2020-01-031-0/+21
| | | | | | | | | | | | | | | As a preparation for adding 64-bit time_t support in the uapi, change the drivers to no longer care about the format of the timestamp field in struct v4l2_buffer. The v4l2_timeval_to_ns() function is no longer needed in the kernel after this, but there is userspace code relying on it to be part of the uapi header.

* media: v4l2-device.h: Explicitly compare grp{id,mask} to zero in v4l2_device ↵Nathan Chancellor2019-12-161-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | macros When building with Clang + -Wtautological-constant-compare, several of the ivtv and cx18 drivers warn along the lines of: drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the result of '<<' to a boolean always evaluates to true [-Wtautological-constant-compare] cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL, ^ drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro 'CX18_HW_GPIO_RESET_CTRL' #define CX18_HW_GPIO_RESET_CTRL (1 << 6) ^ 1 warning generated. This warning happens because the shift operation is implicitly converted to a boolean in v4l2_device_mask_call_all before being negated. This can be solved by just comparing the mask result to 0 explicitly so that there is no boolean conversion. The ultimate goal is to enable -Wtautological-compare globally because there are several subwarnings that would be helpful to have. For visual consistency and avoidance of these warnings in the future, all of the implicitly boolean conversions in the v4l2_device macros are converted to explicit ones as well.

| * cec: add cec_adapter to cec_notifier_cec_adap_unregister()Hans Verkuil2019-10-071-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream. They are not exported to the public V4L2 API since reworking this API will likely be needed for covering various use-cases and new hardware. Multi-slice decoding is exposed as a valid decoding mode to match current H.264 support but it is not yet implemented. The interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

| | | | | | | | | | | | | Separate the i2c helpers to v4l2-i2c.c, in order to get rid of the ifdefery. No functional changes intended, this is just a cosmetic change to organize the code better. Given I2C is a tristate symbol, a hidden boolean symbol is introduced, to make the conditional build easier.

* media: uapi: h264: Add the concept of start codeEzequiel Garcia2019-08-191-0/+6
| | | | | | | | | | | | | | | | | | | | Stateless decoders have different expectations about the start code that is prepended on H264 slices. Add a menu control to express the supported start code types (including no start code). Drivers are allowed to support only one start code type, but they can support both too. Note that this is independent of the H264 decoding mode, which specifies the granularity of the decoding operations. Either in frame-based or slice-based mode, this new control will allow to define the start code expected on H264 slices.

| | | | | | | | | | | | | | | | | Some stateless decoders don't support per-slice decoding granularity (or at least not in a way that would make them efficient or easy to use). Expose a menu to control the supported decoding modes. Drivers are allowed to support only one decoding but they can support both too. To fully specify the decoding operation, we need to introduce a start_byte_offset, to indicate where slices start.

However, as we will now introduce a start code menu control, give the pixel format a more meaningful name, while it's still early enough to do so.

* media: v4l2-async: Get fwnode reference when putting it to the notifier's listSakari Ailus2019-07-251-2/+3
| | | | | | | | | | | | | | | | | | The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of the added fwnode, relying on the caller to handle that instead, in essence putting the fwnode to be added if there was an error. As the reference is eventually released during the notifier cleanup, this is not intuitive nor logical. Improve this by always getting a reference when the function succeeds, and the caller releasing the reference when it does not *itself* need it anymore. Luckily, perhaps, there were just a handful of callers using the function.
