Remove codegen

2016-03-10T15:57:08+00:00

Codegen generates code specific to spice-common submodule. It's not
meant as a generic protocol header or specification. See discussion and
commits about spice-common codegen re-import.

protocol: Add support for the VP8 and h264 video codecs

2016-03-03T17:04:44+00:00

Clients that support multiple codecs must advertise the
SPICE_DISPLAY_CAP_MULTI_CODEC capability and one
SPICE_DISPLAY_CAP_CODEC_XXX per supported codec.

macros: do not use more type safe CONTAINEROF version if not requested

2016-03-02T12:05:55+00:00

This prevents incompatibility if users (like old spice-server/spice-gtk)
are not expected to have this additional restriction.

codegen: simplify FdType

2016-01-19T14:43:23+00:00

This patch is a left-over from the fd passing commit 267391c8fd as
suggested by Frediano Ziglio during review.

protocol: add unix GL scanout messages

2016-01-14T11:52:41+00:00

Add 2 new messages to the display channel to stream pre-rendered GL
images of the display. This is only possible when the client supports
SPICE_DISPLAY_CAP_GL_SCANOUT capability.

The first message, SPICE_MSG_DISPLAY_GL_SCANOUT_UNIX, sends a gl image
file handle via socket ancillary data, and can be imported in a GL
context with the help of eglCreateImageKHR() (as with the 2d canvas, the
SPICE_MSG_DISPLAY_MONITORS_CONFIG will give the monitors
coordinates (x/y/w/h) within the image). There can be only one scanount
per display channel.

A SPICE_MSG_DISPLAY_GL_DRAW message is sent with the coordinate of the
region within the scanount to (re)draw on the client display. For each
draw, once the client is done with the rendering, it must acknowldge it
by sending a SPICE_MSGC_DISPLAY_GL_DRAW_DONE message, in order to
release the context (it is expected to improve this in the future with a
cross-process GL fence).

The relation with the existing display channel messages is that all
other messages are unchanged: the last drawing command received must be
displayed. However the scanout display is all or nothing. Consequently,
if a 2d canvas draw is received, the display must be switched to the
drawn canvas. In other words, if the last message received is a GL draw
the display should switch to the GL display, if it's a 2d draw message
the display should be switched to the client 2d canvas.

(there will probably be a stipped-down "gl-only" channel in the future,
or support for other streaming methods, but this protocol change should
be enough for basic virgl or other gpu-accelerated support)

protocol: learn to describe fd passing in messages

2016-01-14T11:46:16+00:00

Add a new type, "unix_fd", used to describe file descriptor sharing via
socket ancillary data (these messages are local only).

The marshaller/demarshaller can't serialize this in memory (consume_fd
implementation is empty), so it is the responsability of the marshaller
user to handle sending and receiving the handles, which are appended at
the end of the message with an extra stream byte (because some Unix
requires sending at least a byte with ancillary data).

Even if there is no fd to send (or if the fd is invalid etc), the
receiver side expects an extra byte anyway.

Use gcc builtin rather than asm for memory barriers

2016-01-08T14:31:38+00:00

This should make things more portable.

On my machine, __sync_synchronize() uses mfence rather than lock; addl;
Looking at the kernel memory barriers, this should be fine:
http://lxr.free-electrons.com/source/arch/x86/um/asm/barrier.h

The kernel favours using mfence, but falls back to lock; addl; when it's
not available (32 bit non-SSE machines).

macros: make SPICE_CONTAINEROF more typesafe

Check the pointer given is the same type as member pointer.
