> Renesas and Mediatek are two SoC vendors that ship large volumes of SGX GPUs, although they are mainly in China and less present in Europe and North America. The Allwinner A31 (unlike A10, A13 and A20) uses SGX as well, but that might turn out a one-time mistake like the previous Exynos5 (5410) that gets rectified in the next version. Still, I don't think there is much hope that the products just go away.
I wouldn't be surprised if some (esp. samsung) keep making a few devices w/ sgx in the near future as a hedge and/or bargaining chip when it comes to discussing cost/schedule with ARM. I suspect sgx 5xx does still have a slight power advantage against mali (would explain why you see it in the exynos5 targeted at phones), although in the area where sgx once was king, they are fading fast.
> On the plus side, the company is actually opening up slightly now, as they are getting their feet wet with contributing upstream Linux architecture support for their Meta CPUs as well as by getting involved in MIPS Linux (ImgTec recently bought MIPS Technologies). I hope they eventually follow the lead of Nvidia, who are also (slowly) getting more open about their GPUs after becoming involved in the community with their Tegra SoCs. Realistically I think it won't happen before we have upstream support on all other major GPUs and they start seeing pressure from the market.
it really would be nice to see IMGtech open up. And ironically (considering how hostile they have been to open src in the past) they are the ones with the most to gain and the least to lose by opening up. Closed source and buggy are really not a great combination.
