Description Damien Hilloulin 2015-01-02 17:40:09 UTC 
Hello,

I have recently bought a Toshiba Satellite L50-B-1HU including a R7M260 based on a Topaz chip. According to AMD CodeXL 1.6 (used on windows), this chip is a member of the recent Iceland chip family for which there is no support in the Linux kernel, nor in the radeon DDX, nor in libdrm.

I have read some articles on the internet, and it seems that this chip is quite the same as the oland version (same number of shaders unit, frequencies etc), so I hoped that it was a simple rebranding.
Therefore I have (naively) tried to add support myself by adding the PCI-ID (0x6900/0x6901) to the radeon drm driver, radeon ddx driver and libdrm and telling that this is an Oland chip. But it doesn't work.

Could it be possible to add support for this chip?

Or if the chip is supposed to be supported only by the same code as for the Tonga chip (that we don't know yet when it will be merged), could it be possible to have some documentation so that I can make some dirty code to make a minimal support for personal use?
(I would like to try Clover on this chip).

Thanks for any help.

Iceland will be supported with the new amdgpu driver, not the existing radeon driver.

Can be closed now :)
Sorry for just remembering now.
