vmwgfx + libkms on VMware hardware 8

[Aani kitita]

Hi,

I 'm trying to test KMS functionality of latest vmwgfx module.
I tried the code from
 http://permalink.gmane.org/gmane.comp.video.dri.devel/42908

as a simple test case, but all I get is a black screen instead
of white as would be expected.

Setup:
VMWare Workstation 8.0.0
Host & Guest distro: kubuntu oneiric (11.10)
libdrm: 2.4.26+git20111003.c82ef03e from xorg-edgers ppa
vmwgfx module: latest git version from freedesktop.org

I 'm trying with ./modeset -s 4 at 6:1024x768

Running the above under strace shows that all underlying ioctls succeed, so
it looks like
this code should work.

It looks like the update command is not sent to the card because if I add
the parameter
svga.forceTraces = "TRUE" to the .vmx file of the VM, I see a white
rectangle as expected
(the mode still doesn't look right though, it looks like the size of the
rectangle is 640x480
instead of 1024x768)

I also get in the vmware.log when I run the above:
2011-10-18T19:21:30.849+02:00| vcpu-0| I120: MKS enabling SVGA

2011-10-18T19:21:38.940+02:00| mks| I120: MKS disabling SVGA

Any ideas on what may be going wrong? VMWare would make a pretty cool
platform
to experiment with several features of the modern open graphics stack like
wayland,
plymouth, flickerless boot, integrated kernel debugger, multiseat etc etc.

I 'll be happy to provide more debugging information on this problem as
needed.

Thanks in advance,
Aani
