Dear all,
As http://www.x.org/docs/via/OGPM_UniChrome_ProII_R108a_Part2_3D_Video.pdf
pags 14 said:
0x200, bit 19 is the "VGA VSYNC Interrupt Mask Enable" ,
it isn't the "VGA VSYNC Interrupt Enable" Bit.
So the patch:
http://patchwork.kernel.org/patch/34963/
seems conflicted with the spec.
It's better to rename VIA_IRQ_VBLANK_ENABLE to VIA_VBLANK_INT_MASK_ENABLE.
