Bug ID: 99618
Summary: AVX Intrinsics Run in GUI thread only
Product: Mesa
Version: 13.0
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Drivers/Gallium/swr
Assignee: [email protected]

I have been implementing a couple of threaded algorithms using
QtConcurrent::blockingMap(indices, Functor).
The functor utilizes AVX/AVX2 instructions for completing the algorithm.
Using the Gallium driver on LLVMPipe, all 8 of my CPU cores are being used
during the algorithm. When I switch to Gallium driver on swr, the CPU0 is the
only cpu being utilized during the algorithm. Only thing different is the
driver.
Any ideas?
