Radeon DRM Changes For The Linux 3.20 Kernel

It is endianess issue. Macs run in big endian mode, while x86 is little endian.

only the old non Intel Macs

It is endianess issue. Macs run in big endian mode, while x86 is little endian. Drivers are tested for little only. That is why IBM made POWER8 bi-endian. You can run it in little endian mode now, and most things would work with simple recompile. RHEL and SUSE now have two POWER ports, little and big endian.

Iirc old Mac PPC's had this same bi-endianness thing. There was some downside with it but I can't remember anymore what. Default is big endian.

What is indirect draw ?

Thanks

What is indirect draw ?

Do you mean indirect rendering, as in direct rendering vs indirect rendering ?

I don't know, that's what the change log says.

It's required for GL4.0.

Basically allows a bunch of input to be calculated completely on the GPU instead of requiring it to be fed from the CPU, which means it can speed things up substantially if your application is able to use it.

So, we need kernel 3.20 for OpenGL >= 4.0 then?

For evergreen, NI, and Cayman hardware? Yes.

I wouldn't be surprised if you would need even more, for something like tesselation shaders, but you'll need at least 3.20.

This feature has already been supported in radeonsi for a while.

FYI: We solved some problems with Mesa on the Linux PowerPC platform. We released some unofficial Mesa packages last year.
