This isn't a problem. See article [EN][0]. Simply put we are significantly below the cap. If somehow we would manage to hit the cap it definitely should be an alarm for investigati…

I am really surprised with RNDA3 support. I have never seen so many issue with iGPU (APU). It started with VP9 decoder issue (e.g. just playing videos on YouTube was enough to trig…

+1 on your initial comment. Exactly how I feel about the current situation. MilkV Oasis with SG2380 would be the end-game for majority of developers, but they are definitely loosin…

To my understanding SiFive continues to offer their selection of core IP. Anyways, I would assume any existing contract would have to be fulfilled for various legal reasons. SG2042…

Upstreasming status: https://rvspace.org/en/new-page/JH7110_Upstream_Plan StarFive Tech. have been upstreaming on kernel, OpenSBI and U-Boot from several weeks now. Of course this …

It could be that decision to not support AVX512 was made very late in product development and thus early batches didn't have chicken bit disabled or/and fused it off. There might b…

Zba, Zbb, Zbc, Zbs (BitManip) have been approved by "Architecture Review" thus I assume they close to being ratified. Probably one of the first new extensions to be available for R…

There are Profiles specs and Platforms specs, that will be regularly updated. This means software has a fixed target on which it can depend.

I am running RX 570 with PCIe + 6-pin connector for the power. These works out-of-the-box due to open source drivers. Older Nvidia cards work too, but you would need to go with old…

For the price point they are going it's plenty enough. That's also enough to boot Linux distributions in headless mode.

IIRC Allwinner has already sent some patches related to RISC-V to kernel and also suggestions to SBI specification. So far the beginning is good. Remember that they are using IP fr…

06:34PM EDT - Q: plans to support RVV 1.0? A: 0.7.1 for now - when we designed, it was still at that level. We are following and working on that yes. From https://www.anandtech.com…

Yesterday I decided to configure unbound on fresh Fedora 28 Beta install and configure it to use DNS-over-TLS to Cloudflare and Quad9. unbound runs as local recursive resolver. Wit…

We are working on Fedora RISC-V.

You may have noticed a flurry of activity at SiFive over the past few days, or seen a tweet [0] or two [1] alluding to secretive and mysterious activity from Palmer and Yunsup! Her…

IIUC, a limited number of people from kernel community knew about this and NDAs didn't exactly allow all the parties work together. The first solutions/mitigations exist (might not…

On ARM (A64, A32, T32) we get CSDB barrier, but it's a hint instruction instead of going via MSR registers. From whitepaper CSDB is 1101_0101_0000_0011_0010_0010_100_11111 Here som…

Cortex A53 and A55 (in-order designs) are not vulnerable to any variant. ARM Ltd. provide details for all of their designs (it's a bit like Swiss cheese, each core is vulnerable to…

Stable ABI. We have done ~Fedora 25 in late 2016 - https://fedoraproject.org/wiki/Architectures/RISC-V and you can even boot that in your browser - https://bellard.org/jslinux/ ABI…
