Nice. I think that covers all the sites with technical Linux audience interested in graphics, all two

Phoronix: Radeon VRAM Optimizations Coming, But Help Is Needed

Got a workload that runs badly on the r600g Radeon Gallium3D driver? You can help fix it! Optimizations are coming to the open-source Radeon Linux driver for video memory usage...

Hi, I have a laptop with a rv710and 512mb vram, so I guess it's the perfect candidate for you.
I have however, one problem with it: the cpu cooling is far too weak. I use TurionPowerControl to enable C1E and htc at startup, if not (and this is a problem in recovery when bypassing sysinit) I can guarantee it ends in an mce followed by a kernel shutdown.
But when it's jumping in and out of htc slowdown, won't the results of your research be severely affected by this malfunction? I don't want to post corrupt data

I try to help however I have couple questions.

At first I use Wsnipex MESA ppa as I mainly use XBMC and Oibaf's PPA not always worked with it.

Question 1.
Do I need to purge Wsnipex PPA before I execute

sudo add-apt-repository ppaibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade

Question 2.
Do I need to restart my desktop before/after update to Oibaf's ppa?

Question 3.
I have Steam games however I do not know when my steam library stored. Where is it? (default)

Question 4.
How and where I need to setup the environment variable?

I know it is basic questions, but not everybody experts here. THANK YOU/

1. Yes.
2. All 3D apps started before the upgrade will still use the old driver, so if you want compiz to use the new drivers, 'yes'.

Are the patches compatible with mesa 10.0.2 ?

I've pushed a stats7 branch, rebased to work with the radeonsi naming changes, and added a 32-bit fix for LFS (2g file limit). Can any SI user test?

How big FPS jumps does it cause for you? A variance within 5% would be well acceptable, but 20% wouldn't.

The latest (stats7) are definitely not, due to the SI renames. stats6 may work, untested.

Produced https://anonfiles.com/file/1382dac3c...d2db9433ce51ee for me, seems to work.

No, damn.
