Bug #: 43125
Summary: [bisected] Start screen in Amnesia too dark after
"Rewrite the way uniforms are tracked and handled"
commit
Classification: Unclassified
Product: Mesa
Version: git
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: jlp.b...@gmail.com
I have a laptop with ATI Technologies Inc Manhattan [Mobility Radeon HD 5400
Series] graphics card and using the r600g driver from mesa. The kernel is Linux
3.2-rc1.
When I start the game of Amnesia - The Dark Descent it offers me a screen where
I can select a profile to play with. This screen is too dark in latest git
checkouts. I did a bisection and this commit was pointed out as problematic:
719909698c67c287a393d2380278e7b7495ae018
mesa: Rewrite the way uniforms are tracked and handled
Switch all of the code in ir_to_mesa, st_glsl_to_tgsi, glUniform*,
glGetUniform, glGetUniformLocation, and glGetActiveUniforms to use the
gl_uniform_storage structures in the gl_shader_program.
A couple of notes:
* Like most rewrite-the-world patches, this should be reviewed by
applying the patch and examining the modified functions.
* This leaves a lot of dead code around in linker.cpp and
uniform_query.cpp. This will be deleted in the next patches.
v2: Update the comment block (previously a FINISHME) in _mesa_uniform
about generating GL_INVALID_VALUE when an out-of-range sampler index
is specified.
