I wonder if open source drivers will eventually circumvent this limit?
- Jonnax 6y agoNvidia PR [1] has stated that it's a bios level feature. And their bioses require signatures. [1] https://twitter.com/bdelrizzo/status/1362619264423747590?s=20 https://twitter.com/bdelrizzo/status/1362619264423747590?s=2...
- lwhi 6y agoI remember years ago (we're talking 20 years), it was possible to circumvent chip level batching between Nvidia Geforce and Quadro. Geforce was the consumer range, and Quadro was used for workstation graphics. They both used the same chip .. but a resistor on the board gave the driver an indication of which range the card belonged to.
- phire 6y agoThey have gotten somewhat better at chip security since then. I remember AMDs Phenom tri-core CPUs being unlockable to quad-core 12 years ago, but nothing really since.
- lasagnaphil 6y agoSadly, the last time I checked the benchmark for the nouveau project (https://www.phoronix.com/scan.php?page=article&item=nvidia-nouveau-2019&num=2 https://www.phoronix.com/scan.php?page=article&item=nvidia-n...), it wasn't even close to being "usable" in terms of performance (need to expect about 10x slowups in games).
- PurpleFoxy 6y agoIt’s because you need to load firmware on the gpu to make it run fast and that firmware is illegal to redistribute and impossible to reimplement since it’s signed. There is nothing the nouveau project can do short of finding an exploit in the cards crypto.
- joombaga 6y agoI was curious if the mining algorithms could be tweaked to avoid detection.
- 15155 6y agoUnless they decide to add more algorithms after the fact, I'd be very surprised and outraged if this detected anything other than Dagger-Hashimoto via its memory access pattern.
