From 30ece903f5470cf80971a5f2dc6924dd62d5d96c Mon Sep 17 00:00:00 2001 From: Robert Butora Date: Mon, 24 Mar 2014 19:41:38 -0300 Subject: [media] media/usb/gspca: Add support for Scopium astro webcam (0547:7303) This patch does not modify existing drivers. It adds subdriver to gspca for DTCS033 (Scopium) webcam for astrophotography. The patch adds dtcs033.c and modifies Kconfig and Makefile.

v1.2.3-18-g5258 From ba76a6e6a5eaa3736df743818394978af456cf70 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 17 Mar 2014 09:54:19 -0300 Subject: [media] v4l2-subdev.h: fix sparse error with v4l2_subdev_notify The notify function is a void function, yet the v4l2_subdev_notify define uses it in a ? : construction, which causes sparse warnings. Replace the define by a static inline function and move it to v4l2-device.h, which is where it belongs since it needs to know the v4l2_device struct. This wasn't a problem when it was a define, but as a static inline function this no longer compiles in v4l2-subdev.h.

Hence the sparse errors. I've replaced this by introducing three variants of the call_ macros: call_*op for int returns, call_void_*op for void returns and call_ptr_*op for pointer returns. That's the bad news. The good news is that the fail_*op macros could be removed since the call_*op macros now have enough information to determine if the op succeeded or not and can increment the op counter only on success. This at least makes it more robust w.r.t. future changes.

It is unknown who the manufacturer of this card is and no drivers were available during development of the patch. According to images found online, the card is originally sold with Linux DVR software. A CPLD on the card prevents the 878A from requesting access to the bus until an initialization sequence has been issued via GPIOs. The implemented sequence uses the minimum number of GPIOs needed to successfully unlock bus access. As there are many more GPIOs connected to the CPLD, it is very likely that some of the others have an influence on the bus arbitration scheduling. This should be investigated further in case of performance issues. The tested card contains an EEPROM on one of the 878A, but it is completely empty (i.e. contains only 0xff), so it is not possible to detect the card.

That's now memset to 0. Without this the reserved array in struct v4l2_plane would be non-zero, causing v4l2-compliance errors. More serious is the fact that data_offset was not handled correctly: - for capture devices it was never zeroed, which meant that it was uninitialized. Unless the driver sets it it was a completely random number. With the memset above this is now fixed. - __qbuf_dmabuf had a completely incorrect length check that included data_offset. - in __fill_vb2_buffer in the DMABUF case the data_offset field was unconditionally copied from v4l2_buffer to v4l2_plane when this should only happen in the output case. - in the single-planar case data_offset was never correctly set to 0. The single-planar API doesn't support data_offset, so setting it to 0 is the right thing to do. This too is now solved by the memset. All these issues were found with v4l2-compliance.

So for single planar formats replace a bytesused of 0 by the length of the buffer, and for multiplanar format do the same if bytesused is 0 for ALL planes. This seems to be what the user really intended if v4l2_buffer was just memset to 0. I'm afraid that just checking for this and returning an error would break too many applications. Quite a few drivers never check for bytesused at all and just use the buffer length instead.

Check for this too in mmap() (you don't want apps mmap()ing buffers used by fileio) and expbuf() (same reason). In addition drivers should be able to check for this in queue_setup() to return an error if an attempt is made to read() or write() with V4L2_FIELD_ALTERNATE being configured. This is illegal (there is no way to pass the TOP/BOTTOM information around using file I/O). However, in order to be able to check for this the init_fileio function needs to set q->fileio early on, before the buffers are allocated. So switch to using internal functions (__reqbufs, vb2_internal_qbuf and vb2_internal_streamon) to skip the fileio check. Well, that's why the internal functions were created...

The vb2 framework will replace this field with the length field if bytesused was set to 0 by the application, which is what happens in practice. Document this behavior.

And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.

In the past closing the fd would free the vb queue since that was part of the file handle struct. Since that was moved to the global struct that no longer happened. This wouldn't be a problem, but the extra QBUF calls that tvtime does meant that the buffer list in videobuf (q->stream) contained buffers, so REQBUFS would fail with -EBUSY. The solution is to init the list head explicitly when releasing the file descriptor and to not free the video resource when calling streamoff. The real fix will hopefully go into kernel 3.16 when the vb2 conversion is merged. Basically the saa7134 driver with the old videobuf is so full of holes it ain't funny anymore, so consider this a band-aid for kernels 3.14 and 15.

This is the case with struct v4l2_window, which contains pointers and is embedded into struct v4l2_format, and that one is embedded into struct v4l2_create_buffers. Unlike some other structs, used as a part of the kernel ABI as ioctl() arguments, that are packed, these structs aren't packed. This isn't a problem per se, but the ioctl-compat code for VIDIOC_CREATE_BUFS contains a bug, that triggers in such 64-bit builds. That code wrongly assumes, that in struct v4l2_create_buffers, struct v4l2_format immediately follows the __u32 memory field, which in fact isn't the case. This bug wasn't visible until now, because until recently hardly any applications used this ioctl() and mostly embedded 32-bit only drivers implemented it. This is changing now with addition of this ioctl() to some USB drivers, e.g. UVC. This patch fixes the bug by copying parts of struct v4l2_create_buffers separately.

Note that while this uses the vb2-dma-sg version, the VB2_USERPTR mode is disabled. The DMA hardware only supports DMAing full pages, and in the USERPTR memory model the first and last scatter-gather buffer is almost never a full page. In practice this means that we can't use the VB2_USERPTR mode. This has been tested with raw video, compressed video, VBI, radio, DVB and video overlays. Unfortunately, a vb2 conversion is one of those things you cannot split up in smaller patches, it's all or nothing. This patch switches the whole driver over to vb2, using the vb2 ioctl and fop helper functions.

File operations on the video device are possible the moment it is registered. Currently, we register the video device for VPE at driver probe, after calling a vpdma helper to initialize VPDMA and load firmware. This function is non-blocking(it calls request_firmware_nowait()), and doesn't ensure that the firmware is actually loaded when it returns. We remove the device registration from vpe probe, and move it to a callback provided by the vpe driver to the vpdma library, through vpdma_create(). The ready field in vpdma_data is no longer needed since we always have firmware loaded before the device is registered. A minor problem with this approach is that if the video_register_device fails(which doesn't really happen), the vpe platform device would be registered. however, there won't be any v4l2 device corresponding to it.

These buffers are used by other drivers in the video pipeline. Add VB2_DMABUF flag to the io_modes of the vb2 output and capture queues. This allows the driver to import dma shared buffers.

They are now fixed. The fixes are explained as follows: - When adding an inbound data descriptor to the VPDMA descriptor list, we intend to use c_rect as the cropped region fetched by VPDMA. Therefore, c_rect->width shouldn't be used to calculate the line stride, the original image width should be used for that. We add a 'width' argument which gives the buffer width in memory. - frame_width and frame_height describe the complete width and height of the client to which the channel is connected. If there are multiple channels fetching data and providing to the same client, the above 2 arguments should be the width and height of the region covered by all the channels. In the case where there is only one channel providing pixel data to the client (like in VPE), frame_width and frame_height should be the cropped width and cropped height respectively. The calculation of these params is done in the vpe driver now. - start_h and start_v is also used in the case of multiple channels to describe where each channel should start filling pixel data. We don't use this in VPE, and pass 0s to the vpdma_add_in_dtd() helper. - Some minor changes are made to the vpdma_add_out_dtd() helper. The c_rect param is used for specifying the 'composition' target, and 'width' is added to calculate the line stride.

For VPE, cropping makes sense only for the input to VPE(or V4L2_BUF_TYPE_VIDEO_OUTPUT/MPLANE buffers) and composing makes sense only for the output of VPE(or V4L2_BUF_TYPE_VIDEO_CAPTURE/MPLANE buffers). For the CAPTURE type, V4L2_SEL_TGT_COMPOSE results in VPE writing the output in a rectangle within the capture buffer. For the OUTPUT type, V4L2_SEL_TGT_CROP results in selecting a rectangle region within the source buffer. Setting the crop/compose rectangles should successfully result in re-configuration of registers which are affected when either source or destination dimensions change, set_srcdst_params() is called for this purpose.

But the decision when to do this, i.e. whether the decode operation on current source buffer produced a destination frame, is wrongly based on "display status". Display status reflects the status of the destination buffer, not source. This used to work for firmwares version <= 6, because in addition to the above, we'd check the decoded frame type register, which was set to "skipped" if a destination frame was not produced, exiting early from s5p_mfc_handle_frame_new(). Firmware >=7 does not set the frame type register for frames that were not decoded anymore though, which results in us wrongly overwriting timestamps of previously decoded buffers (firmware reports the same destination buffer address as previously decoded one if a frame wasn't decoded during current operation). To do it properly, we should be basing our decision to copy the timestamp on the status of the source buffer, i.e. "decode status". The decode status register values are confusing, because in its case "display" means "a frame has been outputted to a destination buffer". We should copy if "decode and display" is returned in it.

We don't check for failure though, which will make us crash with the codec accessing random memory. We shouldn't be failing STREAMON with out of memory errors though. So move the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also, move MFC instance opening and closing to REQBUFS as well, as it's tied to allocation and deallocation of private codec buffers.

If the size of the buffer is larger than the consumed stream, it assumes that there are more frames in the buffer and that the buffer should be resubmitted for decode. This rarely works though and actually introduces problems, because: - v7 firmware will always return consumed stream size equal to whatever the driver passed to it when running decode (which is the size of the whole buffer), which means we will never try to resubmit, because the firmware will always tell us that it consumed all the data we passed to it; - v6 firmware will return the number of consumed bytes, but will not include the padding ("stuffing") bytes that are allowed after the frame in VP8. Since there is no way of figuring out how many of those bytes follow the frame without getting the frame size from IVF headers (or somewhere else, but not from the stream itself), the driver tries to guess that padding size is not larger than 4 bytes, which is not always true; The only way to make it work is to queue only one frame per buffer from userspace and the check in the kernel is useless and wrong for VP8. So adding VP8 also along with H264 to disallow re-submitting of buffer back to hardware for decode.

This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.

I was able to simulate this bug too. I also noticed that, sometimes, changing channels with au0828, the same thing happens. Most of the issues seem to be due to some hardware bug, that causes the device to not fill all the URBs allocated. When the bug happens, the only known fix is to either replug the device, or to send an USB reset to it. There's also a hack a the au0828 driver that starts a thread that tries to reset the device when a package doesn't start with a sync. One of the culpits for this bad hardware behavior seem to be caused by the lack of stopping and restarting the stream every time a new channel is set. This patch warrants that the stream will be properly reset every time the set_frontend callback is called, partially solving the problem. A complete fix, however, would also need to check the PM conditions for the tuner and demux.
