Vulkan lavapipe software rendering is working on Haiku

Development

Very nice, I wish I could help with testing, but I don’t have the means to get a computer with a Radeon GPU at the moment :frowning:

107

If the RADV port goes far enough to need it, I could help with testing on Polaris (RX 560X), Vega (RX Vega 8), and Navi (RX 5700 XT) GPUs.

Render loop is running. But currently it don’t render anything yet. Most part of interaction with graphics card is not yet implemented.

Major parts needed to be implemented:

  1. Initialization and acquiring information.
  2. Graphics memory allocation (AMDGPU_GEM_CREATE).
  3. GPU virtual memory mapping (AMDGPU_GEM_VA).
  4. Sending command buffers to GPU ring buffers (AMDGPU_CS).
  5. Handling interrupts to know when command execution completed (AMDGPU_WAIT_CS).

Old Linux radeon driver can be used as reference because it is smaller and easier to understand.

Do you mind if i share this post at Phoronix ?

OK to share. Keep in mind that hardware rendering is not actually working yet, many parts are not properly connected to hardware for now.

I have pile of Radeon cards ranging from Fiji all the way up to Navi RDNA2 if you need someone to help test or debug. I also know some stuff about Vulkan.

Radeon HD 7760m here, but I don’t know how to make it start instead of the intel HD 4000 of the cpu in HAIKU

115

You can blacklist intel_extreme driver in boot loader.

That graphics card should support Vulkan if I am correct.

supports mantle, the ancestor of vulkan but unfortunately no drivers for vulkan have been developed in the other OS, so I don’t know

What is its PCI device ID?

My laptop is a Toshiba Satelite P70-B-10U, with AMD Radeon™ R9 M265X and Intel HD 4600.
Can you give an example for the blacklist for Intel HD 4600?

  1. Repeately press space bar to enter boot loader menu.
  2. Select “Safe mode options”.
  3. Select “Blacklist entries”.
  4. Select /addons/kernel/drivers/dev/graphics/intel_extreme.

Thank you X512.

You don’t need to repeatedly press it (at least, I don’t). I find it easier to turn on computer, wait for the hard drive to light up the first time, and then just hold the spacebar down until the menu appears.

That’s for real hardware. For a VM, it gets a bit trickier.

Vulkan drm amd gpu driver work on the hd2000 and up cards

124

are you referring to linux?
truly?
Until a couple of years ago it was not compatible, then I put the egpu gtx 1060 and I didn’t worry about it anymore

Vulkan non-candidate.
