Known bugs

• When you first change an input, the video sometimes is grey. For now just re-choose the input and the palette will correct itself. This apparently also happens on startup on NTSC hardware.
• I2C client handling should _really_ be much better: Find the chips when /dev/video or /dev/radio is opened, and this time do it thoroughly! Lock the chip drivers when they are found, and release them when /dev/video or /dev/radio is closed.
• Does not work if i2c-algo-bit.o is loaded with bit_test=1
• Capture isn't interrupt-driven yet.
• Audio control for the video device isn't implemented.
• Muting is broken in the radio device.
• Doesn't like XFree version 4

ToDo (recent additions)

• Make radio tuning work correctly on both NTSC and PAL hardware.
• Examine register dump after running win98, and see what's useful for us.
• Check, that Chipset init doesn't interfere with I2C and DDC drivers.
• Tristate unused lines.
• Try: VMI_CS_N=1, VMI_DS_N/VMI_RD_N=1, VMI_RW_N/VMI_WR_N=1, DTACK_N/RDY=0
• Reset VMI on load, release reset on device open.
• Try changing pixel buffer refill thresholds to 16.
• Win98 drivers set VMI address to 3, what's that???
• DTACK_N/RDY=1 when video input acivates.
• Try weave de-interlacing (and BOB too).
• Win98 seems to use Chrontel TV-out interface, maybe not initialized?
• vsync in is active low in Win98
• GPIO[1] should probably be set to 0.
• Video in decimation. Dest size=806,364
• Error size 768,304 (taken from Win98???)
• Win98 uses only double buffering, screws up triple buffering?
• Video in stride should be 0x600, adjust triple buffers accordingly.

ToDo (long-term plans)

• Implement weave and bob deinterlacing.
• Automagic loading of the necessary modules. ``modprobe 3tv'' should be enough.
• Automatic video norm detection and change monitoring, when "AUTO" is selected.
• Spinlocks for SMP systems.
• Use atomic operations for device busy detection.
• Videotext
• Make it use the "standard" i2c-voodoo3 driver for I2C operation.
• Reset the video processor when the screen resolution changes.
• Make the overlay window scroll correctly if virtual resolution is bigger than the real resolution.
• V4L2 support.
