I'm not talking about bugs...I'm not talking about bugs...Posted Aug 21, 2011 8:19 UTC (Sun) by khim (subscriber, #9252)In reply to: This is are totally different issues... by BenHutchings Parent article: Avoiding the OS abstraction trap
A lot of drivers contain workarounds for buggy hardware. I'm not talking about these. I'm talking about the fact that each new generation of GPU chips have totally different initialization sequences and even basic operations often require totally different driver. AFAIK videodrivers are more-or-less unique in this regard. 802.11n WiFi card have driver almost identical to what 801.11b had - even if chip internals are wildly different. Yes, I know, GPUs are significantly more complicated... well, they are not more complicated then CPUs and these can reuse older software just fine. About the only piece of silicone comparably buggy were winmodems - and these, too, were brought to life by the promise to paper over hardware problems in software.
