Bug ID: 93110
Summary: [NVE4] textureSize() and textureQueryLevels() uses a
texture bound during the previous draw call
Product: Mesa
Version: 10.5
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Reporter: joseph.kucia-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
QA Contact: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

--> https://bugs.freedesktop.org/attachment.cgi?id=120124&action=edit
A small program to demonstrate the issue
It seems that a texture bound in the previous draw call is used by
textureSize() and textureQueryLevels() (instead of the currently bound
texture).
The attached program demonstrated the bug. When the program is built with
-DBROKEN, it incorrectly prints "width: 2.000000 height 2.000000 miplevels
2.000000" while the current texture is 512x256 with 4 miplevels.
OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NVE4
OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.0.5
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 760]

I think it's because the first 8 textures are bound in multiple slots for some reason. However seems prudent to use these the same way as regular texturing, esp in the case where there are more than 8 textures bound. Signed-off-by: Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> I really couldn't find an effect that it practically had at the time. I could spend time thinking about what the difference is, but... I'm insufficiently interested. I'll ask for a cherry-pick to the 11.0 branch. -- You are receiving this mail because: You are the QA Contact for the bug. You are the assignee for the bug.
