I try to start WarCraft 3 under wine, it's started successfully but exited
afted 3 seconds of main screen with error 
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See
dmesg for more info.

in dmesg i found 

[ 7455.848226] [drm:radeon_cs_parser_init] *ERROR* cs IB too big: 16469
[ 7455.848231] [drm:radeon_cs_ioctl] *ERROR* Failed to initialize parser !


If I set software tcl - game works fine.

Here is an bugreport in ArchLinux bugzilla 
https://bugs.archlinux.org/task/23155?project=1&opened=4027

Tell me please, if you need additional information

When I increase command buffer to 32 kb via driconf - game starts perfectly
with hardware tcl. But than it's exited with error  
warcraft\war3.exe: radeon_common.c:1250: rcommonEnsureCmdBufSpace: Assertion
`rmesa->cmdbuf.cs->cdw' failed.
Then i try manually edit ~/.drirc and change command buffer to 34 kb and game
runs without errors. 
So this bug has an workaround, but i think that it's need to be fixed

Please attach your xorg log, dmesg output, and glxinfo output.  Some of the
commands that are added mostly likely for the tcl-related registers are not
properly accounted for.  I'd start with r200EnsureEmitSize() in r200_tcl.c and
make sure it's properly accounting for all the state that needs to be emitted. 
Print out what size it expects vs. what size gets emitted for each bit of state
and track down where the count is off.

can you tell me, how can i find what size it expects and what size gets emitted
for each bit of state
and track down where the count is off?

and one moment about  "I'd start with r200EnsureEmitSize() in r200_tcl.c"
rv200 is an R100-based chipset, so driver is r100

radeonEnsureEmitSize() in radeon_tcl.c is called from radeon_run_tcl_render().
radeonEnsureEmitSize() walks through the pending state to make sure it will all
fit in the current command buffer, but it appears to be missing some additional
state that's being emitted.  If you run the game from the terminal, it should
print out a warning:
   if (emit_end < rmesa->radeon.cmdbuf.cs->cdw)
      WARN_ONCE("Rendering was %d commands larger than predicted size."
          " We might overflow  command buffer.\n", rmesa->radeon.cmdbuf.cs->cdw
- emit_end);


Most likely:
radeonEmitArrays()
radeonEmitEltPrimitive()
radeonEmitPrimitive()
is emitting more state than radeonEnsureEmitSize() thinks it should.

no, there is no any warnings.

With default settings i see 

drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See
dmesg for more info.
and
[63763.072946] [drm:radeon_cs_parser_init] *ERROR* cs IB too big: 16403
[63763.072950] [drm:radeon_cs_ioctl] *ERROR* Failed to initialize parser !
in dmesg

or with setup command buffer to 32 i see
radeon_common.c:1250: rcommonEnsureCmdBufSpace: Assertion
`rmesa->cmdbuf.cs->cdw' failed.
when try to start a game
