media: pci: add AVMatrix HWS capture driver

2026-05-12T07:39:02+00:00

Add an in-tree AVMatrix HWS PCIe capture driver. The driver supports
up to four HDMI inputs and exposes the video capture path through
V4L2 with vb2-dma-contig streaming, DV timings, and per-input
controls. Audio support is intentionally omitted from this
submission.

This patch also adds the MAINTAINERS entry for the new driver.

This driver is derived from a GPL out-of-tree driver.

Changes since v6:
- v6 accidently contained legacy history, resubmitting with latest
- remove an unused mode-change label reported by W=1

Changes since v5:
- keep queue_setup() and alloc_sizeimage on the logical sizeimage value
- drop the dead queue_setup() fallback that rebuilt pix.sizeimage
  on the fly
- clarify that hws_calc_sizeimage() models the packed-YUYV-only path
- add Assisted-by attribution for Codex

Changes since v4:
- replace plain 64-bit elapsed-time divisions in debug logging with
  div_u64() so i386 module builds do not emit __udivdi3 references

Changes since v3:
- fold the MAINTAINERS update into this patch so per-patch CI sees the
  new file pattern
- wrap the validation text for checkpatch

Changes since v2:
- keep scratch DMA allocation on a single probe-owned path
- avoid double-freeing V4L2 control handlers on register unwind
- drop the extra per-node resolution sysfs ABI
- turn live geometry changes into explicit SOURCE_CHANGE renegotiation
- report live DV timings and reject attempts to retime a live source
- stop advertising RESOLUTION source changes for fps-only updates
- keep live fps state across harmless S_FMT restarts
- stop exposing an unvalidated DV RX power-present signal
- clean the imported sources for checkpatch and W=1 builds

Validation:
- build-tested with W=1 against a local kernel build tree
- compiled the driver with ARCH=i386 allmodconfig and verified the
  resulting hws_pci.o, hws_video.o, and hws.o do not reference
  __udivdi3
- v4l2-compliance 1.33.0-5459 from v4l-utils commit
  4a0d2c3b4f523406cb9a6f4c541ef14f72f19f3d on /dev/video2:
  48 tests succeeded, 0 failed, 1 warning

DV_RX_POWER_PRESENT is intentionally left unsupported in this revision
because current hardware evidence does not expose a validated
receiver-side power-detect signal distinct from active video presence.

media: remove STA2x11 media pci driver

2025-04-25T13:14:25+00:00

With commit dcbb01fbb7ae ("x86/pci: Remove old STA2x11 support"), the
STA2X11 Video Input Port driver is not needed and cannot be built anymore.

Remove the driver and its reference in media documentation.

media: pci: mgb4: Added Digiteq Automotive MGB4 driver

2023-10-07T08:51:58+00:00

Digiteq Automotive MGB4 is a modular frame grabber PCIe card for automotive
video interfaces. As for now, two modules - FPD-Link and GMSL - are
available and supported by the driver. The card has two inputs and two
outputs (FPD-Link only).

In addition to the video interfaces it also provides a trigger signal
interface and a MTD interface for FPGA firmware upload.

media: Revert "media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci"

2023-02-09T08:22:36+00:00

This reverts commit e33fdb5a02490059e2f48ced2c038c8a46c6476d.

The saa7146-based devices are still in use, esp. for DVB. So move
these drivers back to mainline.

media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci

2022-08-29T14:46:38+00:00

Deprecate the hexium_gemini, hexium_orion, mxb and ttpci saa7146-based
drivers: these drivers do not use the vb2 framework for video streaming,
instead it uses the old videobuf framework.

We want to get rid of these old drivers, so deprecated these for future
removal.

Deprecate the meye driver. This driver does not use the vb2 framework
for video streaming, instead it implements its own version.

media: zoran: move to mainline

2022-08-29T13:33:45+00:00

The zoran driver can be moved back to mainline after it has been
converted by Corentin Labbe to vb2.

Note that the zoran driver no longer supports video output, but
video capture is working fine now.

media: Makefiles: sort entries where it fits

2022-03-14T08:42:59+00:00

Alphabetically sort entries at the Makefiles per group,
in ASCII order, e. g., using the output of:

	$ LC_ALL=C sort Makefile |grep obj-y
	...
	$ LC_ALL=C sort Makefile |grep obj.*CONFIG
	...

media: zoran: move to staging in preparation for removal

2018-05-25T19:21:36+00:00

This driver hasn't been tested in a long, long time. The hardware is
ancient and pretty much obsolete. This driver also needs to be converted
to newer media frameworks (vb2!) but due to the lack of time and interest
that is unlikely to happen.

So this driver is a prime candidate for removal. If someone is interested
in working on this driver to prevent its removal, then please contact the
linux-media mailinglist.
