Problem with ACPI and vmware

Problem with ACPI and vmware

[Francis Yom]

Hey guys,

I'm having a problem with ACPI and VMWare.  I am using ACPI 20021101 and
VMWare 3.0 on kernel 2.4.19 with xfs and rmap14a.  My laptop is a Compaq
presario 2700T.

When I include processor and thermal support in the kernel, I can see my
battery and thermal zones just fine.  However, My Win2K and openbsd 3.2
VMWare sessions stutter and are slow.  YES!  I did install the Idle
patch.  In fact, with 20021101 ACPI it seems this patch is already in
place.

When I remove processor and thermal support, I cannot see my battery any
more, but VMWare sessions run fine without problems.

I am looking for a solution that will give me my battery support back
and let me run VMWare without sluggishness.

Can anyone suggest a solution?  Thanks!
Francis

Patch for 20021118 for 20021101?

[Francis Yom]

Hi,

Can someone post a diff patch for 20021118 against a kernel modified
with 20021101?

Thanks!

Francis

Please look at:

and also at:

My opinion is the same as Andy Groover.  Basically, it is a bug in
vmware, so vmware people have to fix that.  Since anybody here
have the source (apart the kernel modules), no one here can help
you.

The only possible workaround at this time for you if really you
want both acpi and vmware is to take a look at:

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

Hi Troy,

Pardon me on the idle patch.  When I looked at my processor.c file, I
realized I was looking at the wrong place and sure enough I did not
disable my 'pm_idle=acpi_pm_idle;' line as directed.  This fixed the
problem completely for me.  Now I just have to get the battstat program
to work ;)

FWIW, I have a Presario 2700 and I am running kernel 2.4.19 with xfs and
rmap14a.  I am running it with the 20021101 ACPI patch and it is working
fine.  I get battery, thermal zones, everything! :)  What made it work
was upgrading the BIOS to the latest F.12 revision which you can get
from compaq.  The F.12 bios has a fixed ACPI implementation and now my
laptop has working ACPI :)  

The only bug I have is that thermal zones are not always picked up at
boot.  I have to reboot (sometimes 2-3 times) and the thermal zones will
get discovered.  I am wondering what might be causing this.  Hmmmm...
Any ideas?

Many thanks!
Francis
