2019-01-21media: cedrus: Allow using the current dst buffer as referencePaul Kocialkowski3-4/+21
It was reported that some cases of interleaved video decoding require using the current destination buffer as a reference. However, this is no longer possible after the move to vb2_find_timestamp because only dequeued and done buffers are considered. Add a helper in our driver that also considers the current destination buffer before resorting to vb2_find_timestamp and use it in MPEG-2.

2019-01-21media: ivtv: add parameter to enable ivtvfb on x86 PAT systemsFrench, Nicholas A2-5/+34
ivtvfb was previously disabled for x86 PAT-enabled systems by commit 1bf1735b4780 ("x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled") as a workaround to abstract MTRR code away from device drivers. The driver is not easily upgradable to the PAT-aware ioremap_wc() API since the firmware hides the address ranges that should be marked write-combined from the driver. However, since a write-combined cache on the framebuffer is only a performance enhancement not a requirement for the framebuffer to function, completely disabling the driver in this configuration is not necessary. Add force_pat module parameter and a corresponding kernel configuration parameter to optionally force initialization on PAT-enabled x86 systems with a warning about the lack of write-combined caching, and document the reasons the driver cannot be easily updated to support wc caching on all systems.

2019-01-16media: imx: Allow interweave with top/bottom lines swappedSteve Longerbeam2-11/+54
Allow sequential->interlaced interweaving but with top/bottom lines swapped to the output buffer. This can be accomplished by adding one line length to IDMAC output channel address, with a negative line length for the interlace offset. This is to allow the seq-bt -> interlaced-bt transformation, where bottom lines are still dominant (older in time) but with top lines first in the interweaved output buffer. With this support, the CSI can now allow seq-bt at its source pads, e.g. the following transformations are allowed in CSI from sink to source: seq-tb -> seq-bt seq-bt -> seq-bt alternate -> seq-bt Suggested-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Steve Longerbeam <slongerbeam@gmail.com> Reviewed-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

2019-01-16media: imx: Fix field negotiationSteve Longerbeam3-23/+76
IDMAC interlaced scan, a.k.a. interweave, should be enabled in the IDMAC output channels only if the IDMAC output pad field type is 'seq-bt' or 'seq-tb', and field type at the capture interface is 'interlaced*'. V4L2_FIELD_HAS_BOTH() macro should not be used on the input to determine enabling interlaced/interweave scan. That macro includes the 'interlaced' field types, and in those cases the data is already interweaved with top/bottom field lines. The CSI will capture whole frames when the source specifies alternate field mode. So the CSI also enables interweave for alternate input field type and the field type at capture interface is interlaced. Fix the logic for setting field type in try_fmt in CSI entity. The behavior should be: - No restrictions on field type at sink pad. - At the output pads, allow sequential fields in TB order, if the sink pad field type is sequential or alternate. Otherwise passthrough the field type from sink to source pad. Move this logic to new function csi_try_field(). These changes result in the following allowed field transformations from CSI sink -> source pads (all other field types at sink are passed through to source): seq-tb -> seq-tb seq-bt -> seq-tb alternate -> seq-tb In a future patch, the CSI sink -> source will allow: seq-tb -> seq-bt seq-bt -> seq-bt alternate -> seq-bt This will require supporting interweave with top/bottom line swapping. Until then seq-bt is not allowed at the CSI source pad because there is no way to swap top/bottom lines when interweaving to INTERLACED_BT -- note that despite the name, INTERLACED_BT is top-bottom order in memory. The BT in this case refers to field dominance: the bottom lines are older in time than the top lines. The capture interface device allows selecting IDMAC interweave by choosing INTERLACED_TB if the CSI/PRPENCVF source pad is seq-tb and INTERLACED_BT if the source pad is seq-bt (for future support of seq-bt).

2019-01-16media: gpu: ipu-csi: Swap fields according to input/output field typesSteve Longerbeam3-49/+89
The function ipu_csi_init_interface() was inverting the F-bit for NTSC case, in the CCIR_CODE_1/2 registers. The result being that for NTSC bottom-top field order, the CSI would swap fields and capture in top-bottom order. Instead, base field swap on the field order of the input to the CSI, and the field order of the requested output. If the input/output fields are sequential but different, swap fields, otherwise do not swap. This requires passing both the input and output mbus frame formats to ipu_csi_init_interface(). Move this code to a new private function ipu_csi_set_bt_interlaced_codes() that programs the CCIR_CODE_1/2 registers for interlaced BT.656 (and possibly interlaced BT.1120 in the future). When detecting input video standard from the input frame width/height, make sure to double height if input field type is alternate, since in that case input height only includes lines for one field.

2019-01-16media: rcar-vin: Allow independent VIN link enablementSteve Longerbeam1-2/+6
There is a block of code in rvin_group_link_notify() that prevents enabling a link to a VIN node if any entity in the media graph is in use. This prevents enabling a VIN link even if there is an in-use entity somewhere in the graph that is independent of the link's pipeline. For example, the code block will prevent enabling a link from the first rcar-csi2 receiver to a VIN node even if there is an enabled link somewhere far upstream on the second independent rcar-csi2 receiver pipeline. If this code block is meant to prevent modifying a link if any entity in the graph is actively involved in streaming (because modifying the CHSEL register fields can disrupt any/all running streams), then the entities stream counts should be checked rather than the use counts. (There is already such a check in __media_entity_setup_link() that verifies the stream_count of the link's source and sink entities are both zero, but that is insufficient, since there should be no running streams in the entire graph). Modify the code block to check the entity stream_count instead of the use_count (and elaborate on the comment). VIN node links can now be enabled even if there are other independent in-use entities that are not streaming.

2019-01-16media: gspca: support multiple pixel formats in TRY_FMTPhilipp Zabel1-2/+8
If a driver supports multiple pixel formats with the same frame size, TRY_FMT will currently always return the first pixel format. Fix this by adding pixelformat support to wxh_to_nearest_mode().

If a driver supports multiple pixel formats with the same frame size, ENUM_FRAMEINTERVALS will currently only work for the first pixel format. Fix this by adding pixelformat support to wxh_to_mode().

The buffer arguments to v4l2_m2m_buf_copy_data args were swapped. The reason is confusing naming conventions in vim2m. It certainly could be improved.

2019-01-16media: vivid: do not implement VIDIOC_S_PARM for output streamsHans Verkuil1-1/+1
v4l2_compliance gave a warning for the S_PARM test for output streams: warn: v4l2-test-formats.cpp(1235): S_PARM is supported for buftype 2, but not for ENUM_FRAMEINTERVALS The reason is that vivid mapped s_parm for output streams to g_parm. But if S_PARM doesn't actually change anything, then it shouldn't be enabled at all.

2019-01-16media: vivid: take data_offset into account for video outputHans Verkuil1-6/+10
The video output sizeimage calculation did not take data_offset into account. This can cause problems with video loopback or exporting output buffers for use as dmabuf import buffers since the output buffer size is now too small.
