             Bug #: 42622
           Summary: [mesa] [r300] mupen64plus invalid command stream
    Classification: Unclassified
           Product: Mesa
           Version: 7.11
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: yoshi314@gmail.com


I've just built mupen64 plus emulator and it crashed after a few seconds (after
emulator intro screen).

When running it, i get something like this :

Core: R4300: starting 64-bit dynamic recompiler at: 0xbc0200
radeon: The kernel rejected CS, see dmesg for more information.

inspecting dmesg gives this output:

[ 4250.120602] [drm:r100_cs_packet_next_reloc] *ERROR* No packet3 for
relocation for packet at 1140.
[ 4250.120607] [drm] ib[1140]=0x000013C6

[ 4250.120625] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !


the same behavior is on current mesa git.

hardware is RV515 (x1300 pro) on 64bit system. 

i'd like to know if that's a program issue, or mesa bug?

I am having the same issue with r300g on rv350 (Radeon 9600). m64+ segfaults
with this output:

Core: Starting R4300 emulator: Dynamic Recompiler
radeon: The kernel rejected CS, see dmesg for more information.
Segmentation fault

The relevant portion from dmesg:

[ 5295.048418] [drm:r100_cs_packet_next_reloc] *ERROR* No packet3 for
relocation for packet at 1044.
[ 5295.048425] [drm] ib[1044]=0x000013C6

This happens with latest mesa git master.

Created attachment 54566
  --> https://bugs.freedesktop.org/attachment.cgi?id=54566
patch

I went ahead and bisected mesa. Here's what I came up with:

12fa91b6753dccbd3aa12c570d1f1e55c7dc0582 is the first bad commit
commit 12fa91b6753dccbd3aa12c570d1f1e55c7dc0582
Author: Thomas Hellstrom <thellstrom@vmware.com>
Date:   Mon Mar 7 11:24:43 2011 +0100

    st/mesa: Fix an incorrect user vertex buffer reference

    st->user_vb[attr] was always pointing to the same user vb, regardless
    of the value of attr. Together with reverting the temporary workaround
    for bug 34378, and a fix in the svga driver, this fixes googleearth on
svga.

The previous commit works. I've attached a patch that simply reverts the
relevant bits.

I've tested on 2.6.38 and 3.0.0 both 32bit.

the problem does not exist anymore on current mesa git and current stable
kernel.

i'll try this on another set of hardware soon to make sure. i might have been a
bit hasty with that comment.
