[maemo-developers] Does anyone know the mechanism in Nokia's LCD driver?

[From: Huang Gao (Gmail)]

Hi, Igor Stoppa:
	Thank you for your reply!
	So can I understand that this hardware FB is not contained in SDRAM
or SRAM, and LCD will refresh itself from this hardware FB by its controller
automatically, without the help of OMAP DMA channel?

Best Regards
Huang Gao(黄杲)
