[Mesa3d-dev] vmware gallium without X, on EGL

[Peter H. <han...@gm...>]

Hello.

I managed to compile Mesa without X for Gallium on vmware SVGA card with 
EGL.
After lot of link problems I managed to get libGL.so compiled and linked.

What was not resolved:
gl_dispatch_stub_361()
gl_dispatch_stub_356()
gl_dispatch_stub_366()
gl_dispatch_stub_362()
gll_dispatch_stub_357()
gl_dispatch_stub_363()
gl_dispatch_stub_358()
gl_dispatch_stub_364()
gl_dispatch_stub_365()
gl_dispatch_stub_359()
glDeleteTexturesEXT()
glGetColorTableParameterfvEXT()
glGetColorTableParameterivEXT()
glGenTexturesEXT()
glIsTextureEXT()
glAreTexturesResidentEXT()
glGetColorTableEXT()

I added stubs.c with empty function bodies and it worked.
eglgears.c is working.

I had to change this:
src/gallium/state_trackers/egl/kms/native_kms.c
in kms_surface_swap_buffers:

   if (ksurf->is_shown && kcrtc->crtc) {
      //err = drmModeSetCrtc(kdpy->fd, kcrtc->crtc->crtc_id,
      //      ksurf->back_fb.buffer_id, kcrtc->crtc->x, kcrtc->crtc->y,
      //      kcrtc->connectors, kcrtc->num_connectors, &kcrtc->crtc->mode);
      //if (err)
      //   return FALSE;
 drmModeDirtyFB(kdpy->fd, ksurf->back_fb.buffer_id, NULL, 0);
   }

Because with drmModeSetCrtc i've got an kernel error:
vmw_ldu_crtc_set_config: DRM_ERROR("Multiple framebuffers not supported\n");

Now I don't know if the backbuffer is correctly displayed. But it works, 
nevertheless.

So my question is what to use to display backbuffer?
Because vmwgfx doesn't support multiple framebuffers on one Crtc, neither 
drmModePageFlip.

I have also questuion to gallium.
What is soft_pipe, llvm_pipe?

Thanks.

There were bugs in the vmwgfx kernel module related to this which have
been fixed in the standalone vmwgfx kernel module repository. Are you
still getting these errors with that?

They're software rasterization drivers, all the work is done by the CPU.
