padoka PPA

PPA description

Hi, this is the UNSTABLE, built from git padoka ppa. if you are looking
for the STABLE padoka PPA, go here:

If you like/use this PPA and think i deserve a cup of coffee, do a Paypal donation:

I don't have the time to support multiple ubuntu versions, so i only provide support for the LTS and the latest. if you need support for older versions, use oibaf repo instead (URL below).

oibaf ppa for reference:

Supported Ubuntu versions:

- 18.04 LTS (bionic)
- 18.10 (cosmic)

LLVM 9.0 git , updated roughly once a week (or when compiles), mesa master git (twice a week on average), intel,radeonsi,amdgpu master git (when there are any).
You just need this PPA and ubuntu 18.04 / 18.10.

I also provide vaapi / vdpau drivers and libs compiled from git.

i added OpenCL support (mesa-opencl-icd package and libclc-*), including updated libclc compiled against LLVM 9.0 and AMDGCN/R600 support.

I also provide VULKAN libs for the INTEL driver and RADEON drivers (radv).

I recently added WAYLAND git to keep up with the changes in modern window managers (kwin, etc).

=== Using gallium-nine ===
Gallium-nine lets you run DirectX 9 games in a faster way, avoiding the inefficent translation of D3D9 calls to OpenGL. For more info see
You need:

 * this PPA
 * wine from this PPA:

 * then to enable gallium-nine run winecfg and enable native DirectX 9 under Graphics tab

To revert to standard Ubuntu drivers type the following in a prompt shell:
$ sudo apt-get install ppa-purge
$ sudo ppa-purge ppa:paulo-miguel-dias/mesa

to Mint users (info provided by Tomasz Molin)

If you're on Linux Mint and you want to ppa-purge, you need to specify the corresponding Ubuntu version of your version of Mint.

For example, Linux Mint 18 is xenial xerus.

So, the command would be:

sudo ppa-purge -d xenial ppa:paulo-miguel-dias/mesa

The documentation provided below was written by Anthony Harrington (, lets give the man a round of applause :D so, without further ado:


Here there be dragons!

    Along with debugging options (see below for a hopefully pretty complete list of possible options), additional features can be enabled on Radeon cards using the "R600_DEBUG" env var. (r600/radeonsi/amdgpu)

    The value of this variable can be set e.g. per individual user via the "~/.profile" config file, or for the entire machine via the "/etc/environment" config file.

    Example contents of the most useful to the average user:


    As of late Jan 2016, Radeonsi and AMDGPU now have the "SI Scheduler" which can be enabled by the user (rather than solely by the package maintainer) by setting "R600_DEBUG=sisched".

    There may be more than this list includes. For better descriptions and to see what is enabled by default for your card, see the man pages. Certain values will require specific (usually later) versions of the software in order to work (for example, the si scheduler requires llvm 3.8+ in order to do anything)!
    The new SI scheduler is not enabled by default, but may be worth enabling if you like, since the option is available.

    Tests on phoronix have shown improved performance, although admittedly sometimes only marginal, depending on the usecase.
    Such features may be subject to slight hiccups during future tweaking to the source (as expected of bleeding edge software). (What works now might not work after a patch, but then suddenly work much better...who knows!)
    The usual risks apply when using this software, and devs cannot be held liable. Bugs are more likely to occur with these new values, but they also present a good way to help debug them! (Double edged sword!)

    Please excuse any errors, this file is intended to help curious mesa users get the most out of their AMD GPU(s).
