* move asm/unaligned.h to linux/unaligned.hAl Viro2024-10-0244-44/+44
| | | | | | | | | | | | | | | | | | | asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
* [tree-wide] finally take no_llseek outAl Viro2024-09-275-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Extron DA HD 4K Plus series of 4K HDMI Distrubution Amplifiers (aka HDMI Splitters). These devices support CEC and this driver adds support for the CEC protocol for both the input and all outputs (2, 4 or 6 outputs, depending on the model). It also exports the EDID from the outputs and allows reading and setting the EDID of the input.

| * media: imx335: Fix reset-gpio handlingUmang Jain2024-08-311-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rectify the logical value of reset-gpio so that it is set to 0 (disabled) during power-on and to 1 (enabled) during power-off. Set the reset-gpio to GPIO_OUT_HIGH at initialization time to make sure it starts off in reset. Also drop the "Set XCLR" comment which is not-so-informative. The existing usage of imx335 had reset-gpios polarity inverted (GPIO_ACTIVE_HIGH) in their device-tree sources. With this patch included, those DTS will not be able to stream imx335 anymore. The reset-gpio polarity will need to be rectified in the device-tree sources as shown in [1] example, in order to get imx335 functional again (as it remains in reset prior to this fix).

Right now we use a usleep_rage() that gives a sleep time of between about 430 and 860 microseconds. On the Lenovo X13s we have observed that in about 1/20 cases the current timing is too tight and we start transacting before the ov5675's reset cycle completes, leading to I2C bus transaction failures. The reset racing is sometimes triggered at initial chip probe but, more usually on a subsequent power-off/power-on cycle e.g. [ 71.451662] ov5675 24-0010: failed to write reg 0x0103. error = -5 [ 71.451686] ov5675 24-0010: failed to set plls The current quiescence period we have is too tight. Instead of expressing the post reset delay in terms of the current XVCLK this patch converts the power-on and power-off delays to the maximum theoretical delay @ 6 MHz with an additional buffer. 1.365 milliseconds on the power-on path is 1.5 milliseconds with grace. 85.3 microseconds on the power-off path is 90 microseconds with grace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When introducing the ability for drivers to indicate the minimum number of buffers they require an application to allocate, commit 6662edcd32cc ("media: videobuf2: Add min_reqbufs_allocation field to vb2_queue structure") also introduced a global minimum of 2 buffers. It turns out this breaks the Renesas R-Car VSP test suite, where a test that allocates a single buffer fails when two buffers are used. One may consider debatable whether test suite failures without failures in production use cases should be considered as a regression, but operation with a single buffer is a valid use case. While full frame rate can't be maintained, memory-to-memory devices can still be used with a decent efficiency, and requiring applications to allocate multiple buffers for single-shot use cases with capture devices would just waste memory. For those reasons, fix the regression by dropping the global minimum of buffers. Individual drivers can still set their own minimum.

Ideally validation of the link between the video device and the subdev should be implemented in that operation. That would however break userspace that does not configure formats on all video devices before starting streaming. While this mode of operation may not be considered valid by the V4L2 API specification (interpretation differ), it is nonetheless supported by the vsp1 driver at the moment and used by at least the vsp1 unit test suite, and possibly other userspace applications. Removing it would be a regression.

It supports subdev-to-subdev links only, and complains if one end of the link is not a subdev. This forces drivers that have video output devices connected to subdevs to implement a custom .link_validate() handler, calling v4l2_subdev_link_validate() for the subdev-to-subdev links, and performing manual link validation for the video-to-subdev links. Video devices embed a media entity, and therefore also have a .link_validate() operation. For video capture devices, the operation should be manually implemented by drivers for validate the subdev-to-video links. For video output devices, on the other hand, that operation is never called, as link validation is performed in the context of the sink entity. As a result, we end up forcing drivers to implement a custom .link_validate() handler for subdevs connected to video output devices, when the video devices provide an operation that could be used for that purpose. To improve that situation, make v4l2_subdev_link_validate() delegate link validation to the source's .link_validate() operation when the link source is a video device and the link sink is a subdev. This allows broader usage of v4l2_subdev_link_validate(), and simplifies drivers by making video device link validation easy to implement in the video device .link_validate(), regardless of whether the video device is an output device or a capture device.

As links get validated in the context of their sink, a call to the helper when the link's sink is not a subdev indicates that the driver has set its .link_validate() handler to v4l2_subdev_link_validate() on a non-subdev entity, which is a clear driver bug. On the other hand, the link's source not being a subdev indicates that the helper is used for a subdev connected to a video output device, which is a lesser issue, if only because this is currently common practice. There are no drivers left in the kernel that use v4l2_subdev_link_validate() in a context where it may get called on a non-subdev sink. Replace the pr_warn_once() with a WARN_ON_ONCE() in this case to make sure that new offenders won't be introduced. A subsequent change will improve the v4l2_subdev_link_validate() helper to properly support validating video device to subdev links.

The correct approach is to have an OF device ID table using i2c_get_match_data() if the devices are registered via OF/ID. Unify the OF/ID table by using MEDIA_BUS_FMT as match data for both these tables and replace the ID lookup table for the match data by i2c_get_match_data() and simplifly probe() and mt9p031_init_state(). While at it, remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing.
