           Summary: ATI Radeon IGP330M/340M/350M Memory manager
                    initialization
           Product: xorg
           Version: 7.4
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

Created an attachment (id=23405)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=23405)
xvinfo, glxgears, Xorg.0.log, dmesg,lsmod, mtrr,  from several of the
configurations.

For some reason the driver seems to fail at Memory manager initialization(which
breaks hw accel) when running under xserver 1.5.2 but works with xserver 1.3.0
& 1.4.2.  I know that its getting the wrong values from
info->FbMapSize-info->FbSecureSize, wherever that comes from.

I've tested a great deal more configurations(and i've tried various xorg.conf
stuff as you can see from the attachment's logs) then listed below, and I'm
willing to try a few more to isolate it, but a pointer in the right direction
would be good re-energizing.

Below is a select subset of configurations I've tested, and a text excerpt of
memory initialization working, and one where it fails(It fails the same way
every time if that helps).
------------------------------------------------------------------------

Works with the following configurations:
xserver 1.3.0, 1.4.2
linux kernel  2.6.21, 2.6.24, 2.6.26, 2.6.27
radeon driver version: 6.9.0


Broken with the following configurations.
xserver 1.5.2  
linux kernel  2.6.21, 2.6.24, 2.6.26, 2.6.27
radeon driver version 6.8.0 6.9.0 6.11.0
(I chroot to a 1.4.2 install when running any of the kernels and it works fine)

-----------------------------------------------------------------------

WORKING OUTPUT(From xserver 1.3.0(1.4.2 agrees with these values))

(II) RADEON(0): Memory manager initialized to (0,0) (1024,8191)
(II) RADEON(0): Reserved area from (0,1024) to (1024,1026)
(II) RADEON(0): Largest offscreen area available: 1024 x 7165
(II) RADEON(0): Will use front buffer at offset 0x0
(II) RADEON(0): Will use back buffer at offset 0x800000
(II) RADEON(0): Will use depth buffer at offset 0xc00000
(II) RADEON(0): Will use 16384 kb for textures at offset 0x1000000

BROKEN OUTPUT(every test with xserver 1.5.2 puts out this)

(II) RADEON(0): Memory manager initialized to (0,0) (3840,2184)
(II) RADEON(0): Reserved area from (0,1200) to (3840,1202)
(II) RADEON(0): Largest offscreen area available: 3840 x 982
(II) RADEON(0): Will use front buffer at offset 0x0
(II) RADEON(0): Will use back buffer at offset 0xffcd8000
(II) RADEON(0): Will use depth buffer at offset 0xe6c000
(II) RADEON(0): Will use 0 kb for textures at offset 0x2000000
