Re: Problem with ACPI and vmware

[Troy Schultz <tschultz-zzOxFVvAfJPQT0dZR+AlfA@public.gmane.org>]

I am not sure what Idle patch you refer to, but I have found that you
must hack processor.c to disable the CPU idle handler in the ACPI
drivers to got VMware to work properly.

The problem seems to be that when VMware's guest is using the CPU the
CPU stays at C2 and is not promoted to C1.  This causes very high delays
in some of the apps.

I am running VMware 3.2 with kernel 2.4.19 and ACPI 20020821, I have
been reluctant to try the newer ACPI drivers since I finally have things
on my Presario 2710CA working quite well.  When I do get some time I do
intend to try the newer ACPI driver though.  It has been a pain to go
through each version and determine where I must hack to disable the CPU
idle handler.

I have also found that I must use a "corrected" DSDT since the one in
the notebook is buggy.

For what it is worth I too think this is an issue that VMware must
correct.  I have sent them emails regarding this issue but have never
seen any response.  I think more people have to complain about this
problem before they will do anything to fix it.

Feel free to email me if I can be of any assistance to you.

Best Regards
