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 investigation. I feel more folks are unhappy because EU was divided into two parts with this.
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 trigger it), but that got fixed after a very long time (required a new firmware). Multiple constant [different] crashes, but you can workaround most of them by adding amdgpu.sg_display=0 to your bootargs. It's already listed in Arch Linux wiki, Gentoo wiki, etc.
Again, I was surprised by the number of firmware and driver issues since RNDA1/2/3 have been around for years now.
+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 loosing money if they keep starting price at 120 USD. They don't have it frozen (they changed the SoC specification some weeks ago) thus I wouldn't be surprised to see this slip into 2025. I wouldn't be surprised if this outperforms MilkV Pioneer.
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 itself is T-HEAD C920 design which is a mess, and might not be even called a RISC-V compliant design. We are kinda stuck it existing and being used in various chips. There are other design issues discovered IIRC (atomic might not work properly [at least on the kernel side workarounds required]; floating point failures in glibc testsuite because FP not being compliant). SG2044 is scheduled for the next year (2024). Not many details are known: 64 cores, 8 DDR controller, 3x memory bandwidth, vector v1.0 support, 2x PCIe (unknown what that means, Gen3 -> Gen4? More lanes?). The cores are unknown, but SG2038 is SiFive P670. T-HEAD has C908 that support vectors v1.0 (and solves some other issues), but that's a smaller core. Not a replacement for C910/C920.
