Hi Claudio,
If the PSCI implementation becomes TCG only, can we also move to a tcg accel
directory? It slowly gets super confusing to keep track of which files are
supposed to be generic target code and which ones TCG specific>

Hi Alex, Fabiano, Peter and all,
that was the plan but at the time of:
https://lore.kernel.org/all/20210416162824.25131-1-cfont...@suse.de/
Peter mentioned that HVF AArch64 might use that code too:
https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg00509.html
so from v2 to v3 the series changed to not move the code under tcg/ , expecting HVF to be
reusing that code "soon".
I see that your hvf code in hvf/ implements psci, is there some plan to reuse
pieces from the tcg implementation now?
I originally reused the PSCI code in earlier versions of my hvf patch
set, but then we realized that some functions like remote CPU reset are
wired in a TCG specific view of the world with full target CPU register
ownership. So if we want to actually share it, we'll need to abstract it
up a level.
Hence I'd suggest to move it to a TCG directory for now and then later
move it back into a generic helper if we want / need to. The code just
simply isn't generic yet.
Or alternatively, you create a patch (set) to actually merge the 2
implementations into a generic one again which then can live at a
generic place :)
