    Phoronix: AMD Posts 459 Linux Kernel Patches Providing Navi Support - 412k+ Lines Of Code

    As we've been expecting, AMD's open-source developers today posted their set of patches enabling Navi (10) support within their AMDGPU DRM kernel driver. Bringing up the Navi support in kernel-space are 459 patches amounting to more than four-hundred thousand lines of code, not counting the work done to LLVM as part of their shader compiler back-end or the yet-to-be-published OpenGL/Vulkan driver patches...

    bridgman or agd5f (or anyone from AMD) Is there any detailed document showing the differences between VCE 4.1 and VCN 2.0?

    ​​​​​​​What I actually want to know is if VCN 2.0 does finally support 4:4:4 encoding besides standard consumer-grade 4:2:0 chroma subsampling encoding.

      Does Mesa need any special bits to handle Navi? For example for radv?

        Sorry for the off-topic, I remember you were interested in a laptop with an AMD APU.

        In the end, I decided to go with a Thinkpad E495 (haven't received mine yet). It's having rather good reviews.

          Yes, as said in the article, Mesa patches will come separately.

            Not to pull this off topic any more but what the world really needs is a web site that details which Ryzen based laptops are running fine on Linux.

            As for this release of software, I'd have to say it is rather impressive for its size and touch many of the components inside the chip. There seems to be a desire on many to poo poo all over Navi but the way I see it this is a major upgrade.

              Also, why the hell aren't there higher display res option available?
              It seems like the notebook companies trying hard to not establish Ryzen APUs in the mid-to-high-end range.
              Is this by pressure of intel?
              Shouldn't be a problem to offer that option.

                Thanks. I'd probably wait until Zen 2 laptops anyway.

                    I'm no expert, but I would doubt it. RX 5700 is made for consumers and gamers, and I would think they don't care.
