I haven't looked at RISC-V much; a quick glance at the ISA spec makes me think it has 32 GPRs? That is nice to see, as with Power slowly fading and Sparc essentially dead, we are stuck with the somewhat more constrained x86-64 and ARM. SBCL, for example, uses 2 stacks in its precise GC, as it will use one stack for unboxed integers and calling out to C, and another for lisp objects, which should be the roots for the…
Yep, it's got 32 GPRs, with #0 hardwired to the constant 0. And the lowRISC project is looking into adding two tag bits with a focus on practical security for languages like C, but with the ability to use them for things like GC. Largest nits I see about the RISC-V ISA is no support for integer math error checking aside from divide by zero (a New Jersey design), and per a slide set I found for the January workshop, t…
Also, don't forget that DRAM isn't the only consumer of physical address space.

There's no way I would spend $100 on something on aliexpress, last time I used them I was shipped an empty bag.
Well you could try to get a chargeback if they don’t deliver a proper product.

The 43-bits; is that a limitation on physical or virtual addresses? Also, don't forget that DRAM isn't the only consumer of physical address space.
I'm assuming it's the virtual address space limit.

depends on the model, I'm sure. I've never had any problems with the battery life, but that's highly subjective to the way people use a laptop. I'm always spending a couple hours here and there at a coffee shop, but I carry my laptop in a messenger bag so having a charger nearby isn't a problem. Plug it in when I need to, don't bother if I don't. I'm always curious why people talk about needing battery life so often.…
I'm in enough places without easy access to outlets. Even in a restaurant (like a Denny's or something) where I'll go without that many outlets. At least the starbucks around my area don't have that many plugs either. Another advantage of having such a long battery life is that I basically can go anywhere after work (where I do have a charger) and not worry about plugging it in at all until the next day. Also, not ha…
