Bug ID: 99974
Summary: Pinned memory is extremely slow on Dolphin
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
When running Dolphin with the OpenGL backend and pinned memory enabled, I get
terrible performance. Getting about 10-20fps in a 60fps game with pinned
memory, and full 60fps without it.
This was discussed on dolphin's IRC channel earlier today, and this PR was made
to disable it. If it gets committed you'll have to use a build without that
code to test it I think.

I'm using an RX460, Linux 4.10.0, mesa/llvm/xorg-server all built from git,
although it happens on older stable versions too.
