           Summary: [r300g] Sins of a Solar Empire crash when entering
                    menu
           Product: Mesa
           Version: git
          Platform: Other

            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org

terminal output

I'm trying to run Sins of a Solar Empire with Wine 1.1.43 and r300g driver.
Until commit dad962bafe8ffd7fdb35c28cfb8bbd5a297c8083 I was able to enter the
menu and even start a new game, however some rendering was broken (almost
everything black). Now when entering menu it crashes. I'm attaching terminal
output and dmesg.

dad962bafe8ffd7fdb35c28cfb8bbd5a297c8083 is the first bad commit
commit dad962bafe8ffd7fdb35c28cfb8bbd5a297c8083
Author: José Fonseca <jfonseca@vmware.com>
Date:   Tue May 4 15:41:19 2010 +0100

    mesa/st: Fill in native program limits.

    In the lack of more fine grained capabilities in Gallium, assume that if
    the pipe driver supports GLSL then native limits match Mesa software
    limits.
    (cherry picked from commit 40a90cd11234a09c2477f5c9984dd6d9fac3f52c)

Hi Pavel,

The commit you mention enables features which were until now never advertised
-- many applications were not using GLSL because they thought the hardware had
no native support for it. It's likely the bug is in the this feature (GLSL
compilation) and not on the commit itself.

Can you get a stack trace showing where inside the driver the crash is
happening?

Jose

I was able to get a Wine backtrace, I hope this is helpful.

From the first log:

"r300: Max size of the constant buffer is 256*4 floats."

immediately followed by abort in the code.

We really need fine-grained shader limits, applications seem to make fatal
decisions based on them.

Could you please re-test the game with current mesa git?

OK so the problem is the game creates a larger constant buffer than hw can
handle, but it seems to use only a small portion of the buffer. I've changed
the code so that it does not abort (commit
93c997a9146e0b50186df684f4847fb0124ada11). Please close the bug if it helps
you.
