media: pci: intel: Add CVS support for IPU bridge driver

2026-05-28T18:18:34+00:00

CVS is located between IPU device and sensors and is available in existing commercial platforms from multiple OEMs. The connection information between them in firmware is not enough to build a V4L2 connection graph. This patch parses the connection properties from the SSDB buffer in DSDT and builds the connection using software nodes. From the IPU bridge point of view, CVS is just like IVSC.

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: ddbridge: add WQ_PERCPU to alloc_workqueue users

2026-05-07T21:30:02+00:00

This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The refactoring is going to alter the default behavior of alloc_workqueue() to be unbound by default. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. For more details see the Link tag below. In order to keep alloc_workqueue() behavior identical, explicitly request WQ_PERCPU.

media: saa7134: Fix a possible memory leak in saa7134_video_init1

2026-05-06T07:05:56+00:00

In saa7134_video_init1(), the return value of the first saa7134_pgtable_alloc() is not checked. If it fails, the function continues as if successful, leaving the driver with an invalid page table. Additionally, if vb2_queue_init() for the VBI queue fails after the video queue page table has been allocated, the allocated memory is not freed before returning. The second saa7134_pgtable_alloc() also lacks a return value check. Errors occur during device probing before the device is fully registered, the normal cleanup path in saa7134_finidev() is not executed, leading to memory leaks and potential use of uninitialized DMA resources. Check the return value of both saa7134_pgtable_alloc() calls and propagate errors. On failure of any later step, free allocated page tables to avoid memory leaks. Ensure control handlers are also released on error to prevent further resource leakage. Found by code review.

media: cx23885: add ioremap return check and cleanup

2026-05-06T07:05:56+00:00

Add a check for the return value of pci_ioremap_bar() in cx23885_dev_setup(). If ioremap for BAR0 fails, release the already allocated PCI memory region, decrement the device count, and return -ENODEV. This prevents a potential null pointer dereference and ensures proper cleanup on memory mapping failure.

media: dm1105: fix missing error check for dma_alloc_coherent

2026-05-05T14:57:02+00:00

The return value of dm1105_dma_map(), which handles DMA memory allocation, is ignored in dm1105_hw_init(). If dma_alloc_coherent() fails, the driver will proceed using a NULL pointer for DMA transfers, leading to a kernel oops or invalid hardware access. Fix this by checking the return value and propagating -ENOMEM on failure. Signed-off-by: Zhaoyang Yu <2426767509@qq.com> Signed-off-by: Hans Verkuil
