Bug ID: 93686
Summary: Performance improvement : Please consider hardware ɢᴘᴜ
rendering in llvmpipe
Product: Mesa
Version: unspecified
Hardware: x86-64 (AMD64)
OS: All
Status: NEW
Severity: enhancement
Priority: medium
Component: Mesa core
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
Purpose : combine software and hardware rendering for better speed performance.
Ok, I recognize this deserve an different purpose from the original one of
llvmpipe, and this might be only possible with Vulkan (probably not with
OpenGl). So I recognize this feature should be optional at run‑time.
The point is some programs are ɢᴘᴜ bound, and the ꜱɪᴍᴅ nature of llvmpipe would
allow to make non negligible benefits, even if it’s slower than an integrated
ɢᴘᴜ.
I recognize this would introduce a complex mechanism for load balancing between
ɢᴘᴜ and ᴄᴘᴜ (avoid ᴄᴘᴜ bounding when there are place for ɢᴘᴜ processing and
vice versa)
Though, my ɢᴘᴜ knowledge is strictly limited to what I learned with OpenCl and
gaming, so I don’t know. But in the case it’s possible, it might worth
discussion please.
