V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder It took three core maintainers, over four years of work, eight new i2c modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac support from Axel Thimm, (hardware) support from Hauppauge, support and assistance from the v4l-dvb people and the many, many users of ivtv to finally make it possible to merge this driver into the kernel.

V4L/DVB: ivtv: Fix ivtv_api_get_data() to avoid unneeded IO during IRQ handling ivtv_api_get_data() was performing more PCI MMIO than needed, resulting often in it accounting for more than half the total time spent in ivtv_irq_handler(). Now it only reads at most 7 of the 16 mailbox data words over the PCI bus, and in some instances only 2 or 3 data words as needed.

V4L/DVB: ivtv: Automatic firmware reload If the firmware has failed, this patch will automatically reload & restart the card. The previous card state will be restored on a successful restart. Firmware reload will only happen if neither the encoder or decoder is active. If the card is busy then behaviour is as before, returning -EIO on device access until the reload can occur. On cards that support video output, coloured bars will be displayed during the reload. Andy Walls (ivtv maintainer and patch committer) made minor tweaks to comments and the logged messages, but nothing substantial otherwise.
