Bug ID: 94835
Summary: Increase fragment shader sample limits from 16 to 32
(AMD Linux - Mesa/RadeonSi)
Product: Mesa
Version: git
Hardware: All
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: esmith@feralinteractive.com
QA Contact: dri-devel@lists.freedesktop.org
Please increase fragment shader sample limits from 16 to 32. This is causing
serious issues with Company Of Heroes 2 as the engine needs more than 16
samplers to correctly render the floor.
Please note: Mesa support 32 samplers with their Intel drivers, but not AMD.
See GL_MAX_TEXTURE_IMAGE_UNITS_ARB in
https://people.freedesktop.org/~imirkin/glxinfo/glxinfo.html
Feral can provide a Steam key to active Mesa engineers working on this issue if
that would help their progress. YOU should be abel to use Intel Mesa as a
reference as that draws correctly as it has a higher texture sampler limit.

Added links to:
94705 - CoH2 specific bug logged by an end user showing the side effect if the
sampler limit is reached on AMD.
91951 - Unsure if exactly the same issue but potentially a similar root cause.
This was logged agains ARMA 3 developer by another developer so I have no
insight other than finding the bug when looking for duplicates before logging.

A little bit off-topic, but would such a key be provided for people working on
drivers other than radeonsi? [r600 and nvc0 come to mind]

By the way, that's only true for Haswell and newer. Ivybridge (gen7) is limited
to 16, at least on Mesa.

I have a preliminary patch set for this, but I still need to put it through its
testing paces.

Any reasonable request from an engineer working on this issue requesting a key
to help with their efforts will be considered.
