If you can access dc state, if you can access the default dc state, then your house is going to be a better place to live.
On a more technical note, it was discovered that the i915 driver for the Intel chipset used by the Intel GPU in the AMD Radeon 9600M integrated graphics card has a bug where the default dc state is 0x2, which matches the state of the graphics card’s dc0. So if for some reason you can’t access this driver, then you won’t be able to access your house either.
The problem is that the i915 driver for the Intel chipset does not provide the same functionality as the AMD Radeon 9600M, which is not a problem.
*error* dc state mismatch (0x0 -> 0x2) is a problem, as it means that the dc state of the graphics card has actually been set to 0x1.
The reason this error message is given is because it is not possible to set the DC state of the graphic card in i915 (you would need to use the i915_set_dc_state function). This problem has already been found in the past, and a fix is in the works. I’ve been told by AMD about this.
You can’t put a dc state on a graphics card without setting it to 0x0. But that is a very strange state to set on a graphics card.
The goal is to show you that your graphics card doesn’t have a dc state, and that your graphics card has no dc state, so you don’t have to set every graphics card state to 0x0.If you want to know more about the solution, I have a link to it.
So the solution is to check the dc state on the graphics card you intend to use to enable/disable dccache, and use that to set all your graphics card states to 0x0.
