Hi John,

I'm happy to see that (pm) it's a scheduled item in your plans! Very
good, definitely very good!

The sooner you guys deliver the goods to the community, the faster
radeonhd (and ATI chips) will grow to become a fully capable and
mature driver/product! :)

Keep up the good work!

Regards,
Ilyes Gouta.

You can put pressure on us to do power management as a higher priority
than 2d/3d acceleration for the newer chips, but I don't think that is
the best way to go. Right now power management is next in line after
6xx/7xx 3D engine support.

Hi,

So to preserve my Radeon HD 3650, I have two options:

1. Re-flash the radeon BIOS with a more adequate PowerPlay table, which
would contain a much lower frequencies for the memory and GPU.
2. Wait for the proper PowerPlay support in radeonhd.

Right?

I think power management is MANDATORY for graphics chips meant to be
embedded into laptops. Any way to put the pressure on AMD/ATI to open up
the documentation for such a feature?

Regards,
Ilyes Gouta.

Hi,

Is there a way to retrieve the GPU temp? Is there any embedded sensor

that can be read out?

Nope. Maybe the Linux Catalyst drivers do this though.


You should be worried about the shorter lifetime of the card due to

high temps.

Yeah, but we're not using any 2D/3D functionality/acceleration under
Linux, so the GPU shouldn't be that hot, is it?

It is hot. GPUs don't seem to have "idle calls" like CPUs. They run
hot all the time unless you reduce the clocks (Catalyst does this).
The fan would stay silent if it wasn't hot (it's BIOS controlled).
