* we don't use all DMA channels at the same time (which will be the
* case most of the time). But that still gives us enougth FIFO space
* to be able to deal with insane long pci latencies ...
*
* FIFO space allocations:
* channel 21 (y video) - 10.0k
* channel 22 (u video) - 2.0k
* channel 23 (v video) - 2.0k
* channel 24 (vbi) - 4.0k
* channels 25+26 (audio) - 0.5k
* channel 28 (mpeg) - 4.0k
* TOTAL = 25.5k
*
* Every channel has 160 bytes control data (64 bytes instruction
* queue and 6 CDT entries), which is close to 2k total.
*
* Address layout:
* 0x0000 - 0x03ff CMDs / reserved
* 0x0400 - 0x0bff instruction queues + CDs
* 0x0c00 - FIFOs

[PATCH] v4l: CX88 updates and card additions - Remove $Id CVS logs for V4L files - add ioctl indirection via cx88_ioctl_hook and cx88_ioctl_translator to cx88-blackbird.c. - declare the indirection hooks from cx88-blackbird.c. - dcprintk macro which uses core instead of dev->core on cx88-video.c. - replace dev->core occurances with core on cx88-video.c. - CodingStyle fixes. - MaxInput replaced by a define. - cx8801 structures moved from cx88.h. - The output_mode needs to be set for the Hauppauge Nova-T DVB-T for versions after 2.6.12. - Corrected GPIO values for cx88 cards #28 & #31 for s-video and composite. - Updated DViCO FusionHDTV5 Gold & added DVB support. - Fixed DViCO FusionHDTV 3 Gold-Q GPIO. - Some clean up in cx88-tvaudio.c - replaced hex values when writing to AUD_CTL to EN_xx for better reading. - Allow select by hand between Mono, Lang1, Lang2 and Stereo for BTSC. - Support for stereo NICAM and BTSC improved. - Broken stereo check removed. - Added support for remote control to Cinergy DVBT-1400. - local var renamed from rc5 to a better name (ircode). - LGDT330X QAM lock bug fixes. - Some reorg: move some bits to struct cx88_core, factor out common ioctl's to cx88_do_ioctl. - Get rid of '//' comments, replace them with #if 0 and /**/. - Minor clean-ups: remove dcprintk and replace all instances of "dev->core" with "core". - Added some registers to control PCI controller at CX2388x chips. - New tuner standby API. - Small mpeg fixes and cleanups for blackbird. - fix mpeg packet size & count - add VIDIOC_QUERYCAP ioctl for the mpeg stream - return more information in struct v4l2_format - fix default window height - small cleanups Signed-off-by: Uli Luckas <luckas@musoft.de> Signed-off-by: Torsten Seeboth <Torsten.Seeboth@t-online.de> Signed-off-by: Nickolay V.
