i2c over aux
Please run the command "ddcutil environment --verbose" and send the output as an attachment. From ddcutil's perspective, there's no difference between a DisplayPort and non-DisplayPort connection. That the video driver emulates the I2C ,I will develope a DisplayPort contorl software by using ATI grahpic card. The software must contain two functions : "I2C-over_AUX" and "native AUX". , display EDID (uses special I2C-over-AUX protocol). – The support of video content protection through HDCP key exchanges. – Determines DisplayPort link transport capabilities by reading DPCD. (DisplayPort Configuration Data) registers. • AUX is also used , AUX to I2C bridge for EDID/MCCS pass through. – Maps on DDC ports. □ Device configuration options. – SPI Flash. – I2C host interface. □ Deep color support. – RGB/YCC (4:4:4) – 16-bit color. – YCC (4:2:2) – 16-bit color. □ Spread spectrum on DisplayPort i, I'm trying to implement DDC/CI with I2C-over-AUX feature within displayport rx subsystem. Through connect an iic slave to the subsystem's edid_iic.,The conversion of I2C-Over-AUX is not needed for a displayPort sink. The clock output, available only in 48-pin version of DP159, is a divided down (datarate/20 or datarate/40) version of the clock feeding the OUT[3:0]P/N. For example for a 5.4 Gbps (HBR2,Hello, According to the DisplayPort and to the SelectIO user guides the Aux Channel signals must be routed to a bidirectional LVDS with 2.5V maximum. ,Also, the DP AUX interface transports. I2C-over-AUX commands and support EDID-DDC communication with LVDS panel. To support panels without EDID ROM, the PTN3460 can emulate EDID ROM behavior avoiding specific changes in system video BIOS. PTN3460 provides, Flexible configuration options (configuring through I2C bus or DP AUX channel and hardware pins) support a wide choice of usage options and panel sizes. ▻ Firmware and EDID Upgrade through Flash-over-AUX utility. ▻ EDID Data Upgrade throughd Flash-over-D, 藉由下達AUX通道指令去進行I2C讀取，來源可自EEPROM讀取EDID數據資料。此資料是用來決定所需的DisplayPort通道的數量。 SerDes初始化. 關於SerDes連結調訓的初始部份，開始於來源針對SerDes時脈和數據回復邏輯，以2.7 Gbps的速度傳輸一個101010的模式以鎖定確切的頻率。在接收器確認此鎖定頻率 ...
