Phoronix: AMD Open-Sources "Addrlib" From Catalyst

As part of AMD finally releasing the AMDGPU kernel driver yesterday along with initial Iceland/Carrizo/Tonga support in Gallium3D, they also open-sourced a component formerly within the Catalyst proprietary driver...

is it worth it?

is it worth it?

Sharing code? Yes.

Sharing code? Yes.

including...?

Forgive my naive and uneducated question, as mesa and 3d graphics driver development is a completely untouched territory for me. I am a developer though, and I was wondering what in a "texture addressing and alignment calculator" needs 22k+ codelines?

There is more than the initial description would indicate I think.

There is a code comment inconsistency on the following lines

+    UINT_32  noOfRanks;          ///  MC_ARB_RAMCFG.NOOFRANK
+                                 ///  0: 1
+                                 ///  1: 2
+                                 ///  SI (R1000) registers-----------------------------------------
+    const UINT_32* pTileConfig;  ///< Global tile setting tables
+    UINT_32  noOfEntries;        ///< Number of entries in pTileConfig
+
+                                 ///< CI registers-------------------------------------------------

It should be

+    UINT_32  noOfRanks;          ///< MC_ARB_RAMCFG.NOOFRANK
+                                 ///  0: 1
+                                 ///  1: 2
+                                 ///  SI (R1000) registers-----------------------------------------
+    const UINT_32* pTileConfig;  ///< Global tile setting tables
+    UINT_32  noOfEntries;        ///< Number of entries in pTileConfig
+
+                                 /// CI registers-------------------------------------------------

At least I think it should be that.

+1 . Mesa use less lines of code now. And I don't like 22k not mesa style codelines (Style is realy crap).

Why didn't they open source this years ago?

Either way, I am glad AMD hired Marek Ol??k, he is a boss!

Hi,

can someone explain what this tool does exactly ?

Thank you

Previous open source function for the same purpose: maybe hundred lines
Opened source from Catalyst blob: 22k lines in horrible style

*cough*
