installing amdgpu-pro and getting vulkan

Hi all !
Well I'm opening this thread because it seems that almost no-one talk about that on the forum and I had a "pretty bad" experience with those drivers to say the least.
First it seems that there is no support from AMD to get other distros than ubuntu/steamOS. As fas as I know they will not try to make any portability effort as long as the driver isn't "good enough". I learned at my last GDC europe that the support of Vulkan in Redhat OSes are done by the redhat guy, not AMD.

On the gentoo side it seems that some wizard tried to make it possible: https://github.com/Lucretia/vulkan-overlay
But it didn't really worked for me. The overlay doesn't work (it is so broken that I used the ebuild as a "tutorial"...). After applying every patch by hand and fixing problem after problem I finally made the dkms part "work".
When I startX I get this: https://github.com/farmboy0/portage-overlay/issues/4
It seems that "AMDGPUPTR" could not get the pointer it wanted in this code: https://github.com/freedesktop-unofficial-mirror/xorg__driver__xf86-video-amdgpu/blob/master/src/amdgpu_kms.c

So I'm here to ask if someone achieved (or tried?) to make amdgpu-pro work on a gentoo 4.7 with a carrizo card.
If the driver is just "no yet ready" then I could help, if it works and I'm dumb then it will produce a basic knowledge for guys like me, if the overlay just needs a little patch then we can fix it and produce a tutorial here.

I'm replying to myself to update the status of vulkan on AMD systems but this time it is not related to amdgpu-pro.

I just learned that there is a openSource initiative to get vulkan on AMD system called "RADV":
it seems to work pretty well:
http://www.phoronix.com/scan.php?page=news_item&px=RADV-Renders-Talos-Principle
and have good overall performance:
https://www.phoronix.com/scan.php?page=article&item=radeon-vulkan-radv&num=1

but I cannot find anything about it on gentoo's documentation or any documentation. I have no more information than "hey it works

" which is good but now I want to install it :cry:

.
I would like to get Vulkan, I don't mind if it's from amdgpu-pro or RADV but both seems really hard to get.
If anyone can give me a hint or help...

If I achieve to get Vulkan using amdgpu-pro or RADV (or any other way) I will write a full tutorial here.

I did something similar, but it works for me, on an overclocked Sapphire Nitro+ RX480 8GB. I'm using kernel 4.4.21.
I first installed vulkan, modifying Luke's ebuild. The modification I did is pretty much the same he also introduced about a week ago, i.e., installing also the header files.
Then I adapted his ebuild to install the latest version of the proprietary driver files (except the module).
Then I installed dkms from farmboy0's overlay, unpacked the dkms source by hand, and fixed that code in a certain number of points. Some of these patches, but not all of them, are the same as Luke's. Some of his I found were actually not needed, while I had to fix other things as well.
Then I built and installed the module, rebooted and all is fine.
Vulkan works, direct rendering works, no crashes, all is fine. I figured I didn't need a kernel > 4.4, since the module is written for Winbuntu 16.04, that uses a 4.4 kernel.
As for kernel options, I found you need CONFIG_VGA_SWITCHEROO, CONFIG_DRM, CONFIG_DRM_FBDEV_EMULATION, CONFIG_FB, CONFIG_FB_MODE_HELPERS, CONFIG_FB_VESA, CONFIG_FRAMEBUFFER_CONSOLE and CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY, some of which may be automatically selected. Also, you need CONFIG_DRM_AMDGPU built as a module with CONFIG_DRM_AMDGPU_USERPTR, and CONFIG_FB_RADEON, also built as a module, with CONFIG_FB_RADEON_I2C and CONFIG_FB_RADEON_BACKLIGHT. Note that you need these options even if you are not building for a laptop because the pro module needs them anyway.
As I wrote, all works fine for me.

I'm curious to know which version of Xorg you have. After installing it X is complaining :

your kernel looks very old

Sorry for the long absence. I just got the latest driver to work. Had to change the dkms source code, and made an ebuild for the rest of the driver. Works fine for me, including Vulkan. Screenshot of the Vulkan smoketest at http://www2.warwick.ac.uk/fac/cross_fac/complexity/people/staff/delgenio/Screenshot_20161029_210132.png. I'm a bit tired now, but at this point I'm thinking I should write a quick guide or something.

I am finally getting something like look close to work !
I forgot the Idea of using amdgpu-pro it create too much problems so I'm trying to get RADV:
I updated my kernel to 4.9 (with sys-kernel/git-sources) and I switched to mesa 13 with media-libs/mesa-9999
for some weird reason I'm stuck to opengl 3.0 but I have shading language 4.30 which does not make any sense (mainly because glsl 430 is linked to opengl 4.3: https://en.wikipedia.org/wiki/OpenGL_Shading_Language )

The libdrm and xf86-amdgpu from AMD is missing, I think. :?:

Any news as the driver now left the beta state and reached version 16.50?

Hey guys I'm coming back with a lot of test and news,
After everything I tried amdgpu-pro is by far the most complex to get vulkan. The easiest is by using Radv.

I did update to the kernel 4.9 and mesa 13.0.2 which leaded to a problem due to how portage is building llvm ( https://bugs.gentoo.org/show_bug.cgi?id=602850 )

Hi all,

I just got the amdgpu-pro-16.50 driver to successfully run the Vulkan cube demo program on my AMD A10-7800 (Kaveri) desktop PC.

My kernel version is linux-4.9, built with the AMDGPU (CONFIG_DRM_AMDGPU) driver.
My LLVM package is sys-devel/llvm-3.9.0-r1
My X11 server package is x11-base/xorg-server-1.18.4
My Mesa package is media-libs/mesa-13.0.2 (built with -vulkan USE flag)

The steps to install the amdgpu-pro-16.50 driver are these:

1. emerge media-libs/vulkan-loader-1.0.30.0
2. Download amdgpu-pro-16.50-362463.tar.xz from AMD.
3. Extract vulkan-amdgpu-pro_16.50-362463_amd64.deb from the download.
4. Extract the contents of vulkan-amdgpu-pro_16.50-362463_amd64.deb into a local directory.
5. Extract libdrm-amdgpu-pro-amdgpu1_2.4.70-362463_amd64.deb from the download.
6. Extract the contents of libdrm-amdgpu-pro-amdgpu1_2.4.70-362463_amd64.deb into the same local directory
7. Copy the following from the local directory to the root directory (/):

Hi all.
Like I said in my last post I cannot get any surface extension, which is a bit inconvenient for a API that aim to display things... I first thought I forgot to install something but trying to compile and install "Vulkan-LoaderAndValidationLayers" did not fix my problem...
when using RADV I get:

Hi ! that's me again !

I'm back on this thread because I tried to install vulkan on my CapeVerde card (R9 M370X, the MacBook pro 2015's GPU)
And everything that could go wrong with it did wrong with install. I even mistakenly deleted /etc in the process because of a typo but that's another story...

I'm posting here to say that:

Hi Folks,

Does anyone know why llvm and clang are (gentoo default) compiled with BUILD_SHARED_LIBS rather than with LLVM_BUILD_LLVM_DYLIB?

From what I've seen it is not generally recommended
https://releases.llvm.org/5.0.0/docs/CMake.html

And leads to problems like:
https://bugs.gentoo.org/617154

When configured with LLVM_BUILD_LLVM_DYLIB, media-libs/mesa-17.3.0_rc2 installs successfully (provided the shared libs are disabled with --disable-llvm-shared-libs), then the runtime error mentioned in bug 61754 no longer exists.

I'm guessing that building with BUILD_SHARED_LIBS might be required by other packages? Tried a few like dev-libs/libclc, but this builds cleanly as well.

Any ideas?
