UbuntuShape on intel i915 (Atom) uses fallback CPU rendering
Status in ubuntu-ui-toolkit package in Ubuntu:
In Progress
Bug description:
I'm digging into unity8 performance problems on older generation Intel
GPUs - specifically i915 Atom GPUs.
I've tested a simple QML file with a single empty UbuntuShape in it:
import QtQuick 2.4
import Ubuntu.Components 1.3
Rectangle {
width: 400
height: 300
color: "blue"
UbuntuShape {}
}
Running it with INTEL_DEBUG=perf env var set, I get this output:
i915_program_error: Exceeded max ALU instructions (76 out of 64)
ENTER FALLBACK 1: Program
Mapping a busy BO, causing a stall on the GPU.
which implies that MESA was unable to compile one of the UbuntuShape
shaders as it created more ALU instructions than the GPU could deal
with. MESA falls back to CPU rendering as a result.
The GPU stall message I guess is related to that.

[Touch-packages] [Bug 1585723] Re: UbuntuShape on intel i915 (Atom) uses fallback CPU rendering
Hi Emanuele, I asked the developer of Ubuntu Shape, and he said the new
(improved!) version of the UbuntuShape should not have this problem.
It will still take a few weeks before that is released though, as there
are a lot of pieces involved.
But still, I hope that's good news for you :)

Bug description:
I'm digging into unity8 performance problems on older generation Intel
GPUs - specifically i915 Atom GPUs.
I've tested a simple QML file with a single empty UbuntuShape in it:
import QtQuick 2.4
import Ubuntu.Components 1.3
Rectangle {
width: 400
height: 300
color: "blue"
UbuntuShape {}
}
Running it with INTEL_DEBUG=perf env var set, I get this output:
i915_program_error: Exceeded max ALU instructions (76 out of 64)
ENTER FALLBACK 1: Program
Mapping a busy BO, causing a stall on the GPU.
which implies that MESA was unable to compile one of the UbuntuShape
shaders as it created more ALU instructions than the GPU could deal
with. MESA falls back to CPU rendering as a result.
The GPU stall message I guess is related to that.

I tried to use unity8 after updating Qtubuntu and I encountered these
problems if I try to open the app crashes unity8 (I can use only the
scopes), the pointer is giant, the system is very slow.

i915_program_error: Exceeded max ALU instructions (76 out of 64)
^^ This means we're very close. The shader is only ~18% longer than the
i915 hardware limit which should be quite feasible to resolve.

[Touch-packages] [Bug 1585723] Re: UbuntuShape on intel i915 (Atom) uses fallback CPU rendering
Ouch, on the hardware I have access to to test on, even a single Ubuntu
Shape in a simple QML file has a massive hit on rendering performance.
Rendering times went up 130ms *per shape*!

FYI: INTEL_DEBUG=all is useful, it shows the opcodes mesa is generating
from your shaders.
