回复给 LVDS。据我所知，没有提供这个接口，所以暂时无法从 GOP 获得。

回复给 Shina。

据我所知，能调整的参数只有：

Integrated Display Configuration ->
LFP Panel Configuration ->
Panel #0X ->
eDP Fast Link Training Configuration Parameters ->
Pre-Emphasis
Voltage Swing

修改之后如果有问题，请联系 Intel FAE 看看是否还有其他办法。

回复给 Intel GOP設定 to diable sDRRS requirement。你这个问题听起来是 GOP 的Bug, 建议确保工具、GOP、VBT都是最新版本，如果仍然有问题，联系 Intel 查看。

因為panel閃頻問題, 需要diable GOP sDRRS設定, 但調整Intel GOP設定 to diable sDRRS卻發現LFP panel configuration的參數都會跟著變動, 尤其是Panel的PWM設定會從PWM0變成PWM1導致panel malfuction.
想請教如果要調整Intel GOP設定 to diable sDRRS for multiple panels, 應該如何設定較為正確

回复给 Mike。

Hi Mike，

Usually we think iGFX is initialized during DXE stage. But as you know, customer want to lighten their display as early as possible. For this reason, IntelGraphicsPeim is a PEI module to prepare a framebuffer for display. After running this module, BIOS can show a pciture on screen. And in DXE stage, IntelGopDriver.efi would fully initialize the graphic card.

Hi Ziv,
The article is simple and beautiful, I have learn a lot.

May I ask your opinion which stage will the GOP initial ready? If my screen not show any logo under pre-OS, wanna check is IntelGopDriver.efi or IntelGraphicsPeim.efi problem.
Since GOP initial ready after capture complete panel EDID, I assume the answer is after DXE stage?

To the article there’s only one suggestion, default panel setting is not Panel#01 but depend on below setting. (the latest GOP are default Panel#03)
“Integrated LFP configuration” -> “Device 1 (LFP1) configuration” -> “Select Panel type”

Best regards,
Mike
