knedlik: the current state of the art is running a 4K page size thin VM based on an OCI image that contains FEX, and using experimental DRM Native Context patches to virglrenderer to achieve macos-like gpu paravirtualisation
<chadmed_>
on fedora using slp's COPR it seems to work quite well already, though packaging for other distros has been a bit of a nightmare
<chadmed_>
lots of moving parts, downstream forks, vendored rust crates, etc at the moment

my annecdotal experience was it worked but was not usable for the games i wanted to play via steam

if memory serves well, the rounding modes are different between x86 and ARMv8, unless the implementation has FEAT_AFP (and SW picks the correct mode).
<j`ey>
it looks like that x86 instruction is round-to-nearest, which seems to be supported before FEAT_AFP too for FCVT (scalar) but that's just for skimming through the arm arm
<j`ey>
(since in this case it's actually a scalar thats needed, not simd)
<maz>
ah, right. as you can tell, FP isn't really my thing! :D
<j`ey>
GP regs are the best! :D

me neither, but maybe my plan worked and I got someone to look at implementing it - it looks like impact might be bigger than some small mutter thing
