ba07fd2f5742e8b0d965003b34c7a44eb4f67e53 - media: pci: add AVMatrix HWS capture driver

Mon, 11 May 2026 01:50:36 +0200

media: pci: add AVMatrix HWS capture driverAdd an in-tree AVMatrix HWS PCIe capture driver. The driver supportsup to four HDMI inputs and exposes the video capture path throughV4L2 with vb2-dma-contig streaming, DV timings, and per-inputcontrols. Audio support is intentionally omitted from thissubmission.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=1Changes 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 CodexChanges since v4:- replace plain 64-bit elapsed-time divisions in debug logging with div_u64() so i386 module builds do not emit __udivdi3 referencesChanges since v3:- fold the MAINTAINERS update into this patch so per-patch CI sees the new file pattern- wrap the validation text for checkpatchChanges 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 buildsValidation:- 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 warningDV_RX_POWER_PRESENT is intentionally left unsupported in this revisionbecause current hardware evidence does not expose a validatedreceiver-side power-detect signal distinct from active video presence.Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202604020522.z22eZuW8-lkp@intel.com/Assisted-by: Codex:gpt-5.5Signed-off-by: Ben Hoff Signed-off-by: Hans Verkuil List of files: /linux/drivers/media/pci/Kconfig

media: pci: mgb4: Added Digiteq Automotive MGB4 driverDigiteq Automotive MGB4 is a modular frame grabber PCIe card for automotivevideo interfaces. As for now, two modules - FPD-Link and GMSL - areavailable and supported by the driver.

Sun, 13 Mar 2022 07:25:46 +0100

media: Kconfig: cleanup VIDEO_DEV dependenciesmedia Kconfig has two entries associated to V4L API:VIDEO_DEV and VIDEO_V4L2.On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core.while VIDEO_V4L2 where used to distinguish between drivers thatimplement the newer API and drivers that implemented the former one.With time, such meaning changed, specially after the removal ofall V4L version 1 drivers.At the current implementation, VIDEO_DEV only does (1): it enablesthe media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenubut it doesn't affect anymore the V4L core drivers.The rationale is that the V4L2 core has a "soft" dependencyat the I2C bus, and now requires to select a number of otherKconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEVIn the past, merging them would be tricky, but it seems that it is nowpossible to merge those symbols, in order to simplify V4L dependencies.Let's keep VIDEO_DEV, as this one is used on some make *defconfigconfigurations.Suggested-by: Laurent Pinchart Reviewed-by: Laurent Pinchart Reviewed-by: Jacopo Mondi Reviewed-by: Neil Armstrong # for meson-vdec & meson-ge2dAcked-by: Andrzej Pietrasiewicz Acked-by: Łukasz Stelmach Signed-off-by: Mauro Carvalho Chehab List of files: /linux/drivers/media/pci/Kconfig

Thu, 26 Mar 2020 15:47:25 +0100

media: Kconfig: fix selection for test driversThere are some long-time mistakes related to build testdrivers, with regards to depends on/select. Also, as wenow want to build any test driver without needing toenable anything else, change the logic in order to properlyfilter them.Please notice that the PCI skeleton is somewhat anexception, as it requires to select *both* SAMPLES andMEDIA_TEST_SUPPORT. I almost changed it to be either one,but decided to keep it as-is, as this is something thatwe don't really need to be included on any distribution.The only reason for someone to build it is for COMPILE_TESTpurposes.Signed-off-by: Mauro Carvalho Chehab List of files: /linux/drivers/media/pci/Kconfig

Wed, 25 Mar 2020 08:36:36 +0100

media: Kconfig: better support hybrid TV devicesRight now, if one has an hybrid TV card, it has to selectboth analog and digital TV support, as otherwise the neededcore support won't be selected.Change the logic to auto-select the core support for thosedrivers, as this is a way more intuitive.It should be noticed that, as now both DVB_CORE and VIDEO_DEVdefaults depends on selecting a hybrid cards, we had to removethe explicit dependencies there, in order to avoid circulardependencies.That requires some tricks:1) the prompt should not be not visible when an hybrid card is selected, as the user shold not change it.2) When a media hybrid device is selected, the modular option for DVB_CORE and VIDEO_DEV will follow the MEDIA_SUPPORT dependency, as we can't have a core built with "y" with a driver built as module.Note: while here, moved two pure V4L2 PCI drivers out of the"hybrid" part of config and consider pvrusb2 as an hybriddevice.Signed-off-by: Mauro Carvalho Chehab List of files: /linux/drivers/media/pci/Kconfig

media: Kconfig: mark other drivers as test driversNeither the PCI skeleton nor the DVB dummy driver are realdrivers.

media: zoran: move to staging in preparation for removalThis driver hasn't been tested in a long, long time. The hardware isancient and pretty much obsolete. This driver also needs to be convertedto newer media frameworks (vb2!) but due to the lack of time and interestthat is unlikely to happen.So this driver is a prime candidate for removal.
