Hello, This patch set adds alpha support to the Renesas VSP1 driver. The feature is split in two parts, support for the alpha component in capture and output buffers, and support for premultiplied colors. Each part requires extensions to the V4L API. The first two patch add new pixel formats for alpha and non-alpha RGB, and extend usage of the ALPHA_COMPONENT control to output devices. They have already been posted separately, for the rationale please see https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg75449.html. The next two patches add a premultiplied alpha flag to the V4L format API. This requires extending the v4l2_pix_format structure first (patch 03/18). Patches 05/18 to 12/18 perform general cleanups and fixes to the VSP1 driver. Please see individual patches for details. Patch 13/18 switches from the old RGB formats to the new XRGB formats. Patch 14/18 then adds support for ARGB formats, and patch 15/18 support for the alpha component control. Patch 16/18 and 17/18 add support for premultiplied colors, and patch 18/18 finally makes the blending unit background color configurable. While I'd of course like to see the VSP1 patches getting reviewed, I expect most of the discussions to concentrate on the first four patches. Several rounds will likely be needed, and I'd like to get the series in v3.17, so let's get started :-) Laurent Pinchart (18): v4l: Add ARGB and XRGB pixel formats DocBook: media: Document ALPHA_COMPONENT control usage on output devices v4l: Support extending the v4l2_pix_format structure v4l: Add premultiplied alpha flag for pixel formats v4l: vsp1: Fix typos v4l: vsp1: Cleanup video nodes at removal time v4l: vsp1: Propagate vsp1_device_get errors to the callers v4l: vsp1: Setup control handler automatically at stream on time v4l: vsp1: sru: Fix the intensity control default value v4l: vsp1: sru: Make the intensity controllable during streaming v4l: vsp1: wpf: Simplify cast to pipeline structure v4l: vsp1: wpf: Clear RPF to WPF association at stream off time v4l: vsp1: Switch to XRGB formats v4l: vsp1: Add alpha channel support to the memory ports v4l: vsp1: Add V4L2_CID_ALPHA_COMPONENT control support v4l: vsp1: bru: Support premultiplied alpha at the BRU inputs v4l: vsp1: bru: Support non-premultiplied colors at the BRU output v4l: vsp1: bru: Make the background color configurable Documentation/DocBook/media/Makefile | 2 +- Documentation/DocBook/media/v4l/controls.xml | 17 +- .../DocBook/media/v4l/pixfmt-packed-rgb.xml | 415 ++++++++++++++++++++- Documentation/DocBook/media/v4l/pixfmt.xml | 53 ++- Documentation/DocBook/media/v4l/v4l2.xml | 8 + .../DocBook/media/v4l/vidioc-querycap.xml | 6 + drivers/media/parport/bw-qcam.c | 2 - drivers/media/pci/cx18/cx18-ioctl.c | 1 - drivers/media/pci/cx25821/cx25821-video.c | 3 - drivers/media/pci/ivtv/ivtv-ioctl.c | 3 - drivers/media/pci/meye/meye.c | 2 - drivers/media/pci/saa7134/saa7134-empress.c | 3 - drivers/media/pci/saa7134/saa7134-video.c | 2 - drivers/media/pci/sta2x11/sta2x11_vip.c | 1 - drivers/media/platform/coda.c | 2 - drivers/media/platform/davinci/vpif_display.c | 1 - drivers/media/platform/mem2mem_testdev.c | 1 - drivers/media/platform/omap/omap_vout.c | 2 - drivers/media/platform/sh_veu.c | 2 - drivers/media/platform/vino.c | 5 - drivers/media/platform/vivi.c | 1 - drivers/media/platform/vsp1/vsp1.h | 14 +- drivers/media/platform/vsp1/vsp1_bru.c | 85 ++++- drivers/media/platform/vsp1/vsp1_bru.h | 9 +- drivers/media/platform/vsp1/vsp1_drv.c | 22 +- drivers/media/platform/vsp1/vsp1_entity.c | 42 +++ drivers/media/platform/vsp1/vsp1_entity.h | 10 + drivers/media/platform/vsp1/vsp1_regs.h | 2 + drivers/media/platform/vsp1/vsp1_rpf.c | 68 +++- drivers/media/platform/vsp1/vsp1_rwpf.h | 2 + drivers/media/platform/vsp1/vsp1_sru.c | 107 ++++-- drivers/media/platform/vsp1/vsp1_sru.h | 1 - drivers/media/platform/vsp1/vsp1_video.c | 124 ++++-- drivers/media/platform/vsp1/vsp1_video.h | 4 +- drivers/media/platform/vsp1/vsp1_wpf.c | 72 +++- drivers/media/usb/cx231xx/cx231xx-417.c | 2 - drivers/media/usb/cx231xx/cx231xx-video.c | 2 - drivers/media/usb/gspca/gspca.c | 8 +- drivers/media/usb/hdpvr/hdpvr-video.c | 1 - drivers/media/usb/stkwebcam/stk-webcam.c | 2 - drivers/media/usb/tlg2300/pd-video.c | 1 - drivers/media/usb/tm6000/tm6000-video.c | 2 - drivers/media/usb/zr364xx/zr364xx.c | 3 - drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 19 +- drivers/media/v4l2-core/v4l2-ioctl.c | 66 +++- include/uapi/linux/videodev2.h | 31 +- 46 files changed, 1001 insertions(+), 230 deletions(-) -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
