Hello, got another card with "too bright" problem: Sapphire Radeon VE 7000 DDR (VGA+S-Video)
lspci -vnn: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV100 QY [Radeon 7000/VE] [1002:5159] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited Sapphire Radeon VE 7000 DDR [174b:7c28]
The patch below fixes the problem for this card.
Applied.
But I don't like the blacklist, couldn't some heuristic be used instead?
How about the attached patch?
The interesting thing is that the manufacturer is the same as the other card needing the same quirk. I wonder how many different types are broken this way.
So far we only have two quirks, so it doesn't seem that widespread.

The "wrong" ps2_pdac_adj value that comes from BIOS on this card is 0x300.
==================== drm/radeon: Add primary dac adj quirk for Sapphire Radeon VE 7000 DDR
Values from BIOS are wrong, causing too bright colors. Use default values instead.
