Readers should be aware that the llano is slightly gimped based on the ram used. I don't know what speed he used (1333/1600 possible?) I get much higher results with 1866. If I am wrong then there is something else gimping his speeds considering this was a budget pc for under $400 and I get better results I can't imagine what.
I just laughed so hard I almost pissed myself.Quote:
In some of the tests, the Intel Ivy Bridge graphics were even quite competitive with the AMD Fusion A8-3870K on AMD's highly-optimized Catalyst Linux driver.
Once I get the GTK GUI functional, I'll post the source location for others to download/hack on.
Mostly, because the tool that I'm writing only targets the sysfs interfaces exposed by the radeon kernel driver. It's a run-time tool, and in its initial form, it will not persist settings across reboots. Most of the options that are disabled by default (2D tiling, PCIe 2, etc) are either kernel parameters or X.org configuration options. If I screw up writing kernel parameters for the user, I can hose a system, make it unbootable, and piss people off. Kernel parameter setting is also distro dependent (grub, lilo, etc). Same argument goes for overriding X.org settings (assuming the system even has an xorg.conf). I can document what settings need to be set, but those already are documented in various Wiki's and man pages, and just need to be summarized.
The sysfs nodes are much safer to read/set, which is why I'm starting there.
What i am still waiting for are xserver 1.11 stabily fixes - when you use kde 4.x and use disable composite for fullscreen apps your xserver can crash or you get completly distorted gfx until you disable composite effects. That problem is not seen on ubuntu 12.04 because they use a frankenstein 1.11 xserver with lots of patches from 1.12. But as debian wheezy/sid does not use those patches it is unstable there. When you don't use that function it is ok, but when you know that on laptops composite is usally disabled when running low on battery and enabled when you connect power again this is definitely bad.
