[Spice-devel] [PATCH RFC 00/12] Remote Virgl support

[Frediano Ziglio]

This patch is an improve to last one. There are still many work
to be done. The main reason I'm posting is to discuss the Qemu
API changes ("Define a new interface for Qemu to pass texture"
patch). This code add dependency to EGL directly.

The main idea is still extracting raw data and passing to the
normal flow (display_channel_process_draw).

Changes from last version:
- this set supports all cards using a different protocol from Qemu
  that now can pass EGL information (display and context) and
  texture directly. This allows spice-server to choose dma buffers
  or just GL data;
- the patch set is much neat.

Multiple clients are still not supported (but actually is not a
regression).

Looks like the queue is reduced automatically by drawable code
in spice-server so new frames replace old ones if network or
streaming code is not fast enough.

If you expect similar performance to the video I posted days
ago you will be disappointed. These video were done with
lot of tweak in the streaming code (both server and client).
I decided to avoid patches for stream code as they are quite
in a bad shape.

Frediano Ziglio (12):
  Define a new interface for Qemu to pass texture
  Add libepoxy to dependency
  Implements spice_qxl_gl_init
  Save and allow to retrieve texture information in Qxl
  Import function to get dma buffer from a texture
  Add get_texture_raw_data to extract raw data from a texture
  Implements spice_qxl_gl_scanout_texture
  Check client is using unix sockets in dcc_gl_draw_item_new
  Do not disconnect client if not connected locally in
    dcc_gl_scanout_item_new
  Add get_dummy_drawable
  Handle remote 3d connections
  Fix a bug... why this happens ??
