15 OpenGL ES 2.0 is required.
19 This extension allows a client to order operations between contexts.
21 This extension implements a small subset of ARB_sync, with weaker
22 guarantees. In particular it doesn't ensure commands are actually executed
23 by the server, it only guarantees submission order.
25 It does however guarantee operation order with respect to
26 ConsumeTextureCHROMIUM and ProduceTextureCHROMIUM from
27 CHROMIUM_texture_mailbox, if present.
37 New Procedures and Functions
41 uint InsertSyncPointCHROMIUM()
43 flushes the stream of commands for the current context and creates and
44 inserts a sync point. The sync point acts as a fence, which is signaled when
45 previous commands have been submitted to the server, or when the context is
46 destroyed, whichever happens first. The sync point name is returned. The
47 sync point is implicitly deleted when it becomes signaled. The sync point
48 namespace is shared between all contexts on the same server, including other
54 void WaitSyncPointCHROMIUM(uint sync_point)
56 causes the current context to stop submitting commands until the specified
57 sync point becomes signaled. This is implemented as a server-side wait.
58 <sync_point> is the name of the sync point to wait for. If <sync_point>
59 isn't a valid sync point returned by InsertSyncPointCHROMIUM, or if the sync
60 point has already been deleted, the command is equivalent to a no-op and no
