As always, this code has not been tested for conformance with the OpenGL
specification. OpenGL conformance testing is available from
http://khronos.org/ and is required for use of the OpenGL logo in
product advertising and promotion.
For master devices, the ptraccel code could segfault on free since we'd be
dereferencing random memory. Callocing the valuatorClassRec is the easy fix.
The check can fail because the output from FBIOGET_VSCREENINFO is used to set
Clock in fbdev2xfree_timing(). Then in fbdevHWSetMode(), xfree2fbdev_timing()
is called which sets the pixclock based on Clock. The resulting circle results
in slight rounding errors, causing the comparision check in fbdev_modes_equal
to fail.
The XEvIE extension doesn't clear the rep.length field for any reply but
the version check. Hence, if there is junk data in it and that is sent
to the client, it hangs.
X.Org bug#17394 (http://bugs.freedesktop.org/show_bug.cgi?id=17394)
- This should allow drivers to recieve post submission events for X<->opengl synchronisation.
- Lacking a testcase, i'm open to suggestion how to do it better.
- The idea is:
- driver recieves event
- driver creates personal identification and inserts marker into X fifo.
- when something wants to use an X pixmap, it checks if something is pending.
- If so, it synchronizes the 2nd fifo using the initial identification.
- Driver is not required to use interrupt based systems (price too high).
- Lower latency is ofcource better.
- If this is somehow unusable for you, then come up with improvements.
- For that reason i wouldn't consider the api fixed for the moment.
- I found no evidence in the protocol, that it should be differently from all the other modes.
- It seems to have been like this from day 1.
- If anyone has evidence to the contrary, please enlighten me.
