flip for that window in progress. The flip will complete, and then
immediately get undone (as we can't stop an in-progress flip).

Remove the vblank->window_destroyed field as we can signal this with
vblank->window == NULL instead.

Change check to vblank->window == NULL in:

present_flip_notify

Add check for vblank->window == NULL in:
present_vblank_notify
present_execute

present_flip_notify was also using vblank->window->drawable.pScreen,

mieq: Bump default queue size to 512

bugs in Red Hat bugzilla with an EQ size message in the log, the
distribution looked like:

String                      | Matches
-------------------------------------
Increasing EQ size to 512   | 460
Increasing EQ size to 1024  | 52
Increasing EQ size to 2048  | 6
Increasing EQ size to 4096  | 0

Most of the "512" ones appear to be mostly harmless, some relatively
expensive path in either rendering or resource destruction simply taking
too long due to external pressures like paging or CPU contention.  So
let's raise the initial queue size, both to reduce the number of
spurious abrt reports and to drop fewer events in all but the most
pathological cases.

kdrive: fix cursor jumps on CursorOffScreen behavior

This patch fixes cursor jumps when there is a grab on the Xephyr window and
the pointer moves outside the window.

So on two side-by-side 640x480 screens, a coordinate of 0/481
triggers KdCursorOffscreen.

If the delta between two screens is 0, they share the same offset for
that dimension. When searching for the new screen, the loop always rules out
the current screen. So we get to the second screen, trigger the conditions
where dy <= 0 and decide that this new screen is the correct one. The result
is that whenever KdCursorOffScreen is called, the pointer jumps to the other
screen.

Change to check for dy < 0 etc. so that the cursor stays on the same screen if
there is no other screen at the target location.

sync: fix corner-case in triggering idle alarms

ProcessInputEvent() resets the device idle times. If idle time was higher than
the lower bracket, this should trigger an event in the idle time wakeup
handler.

If processing is slow, the idle time may advance past the lower bracket

never schedule a wakeup to handle the event, causing us to randomly miss

glx: convert to direct GL dispatch (v2)

We now expect to be linked against something that provides the GL API,
instead of manually grubbing about in the DRI driver's dispatch table.
Since the GLX we expose calls GL functions that are meant to be looked
up dynamically, also add a way to thunk through to GetProcAddress.

This includes a refresh of the generated sources, which requires a
correspondingly new Mesa.

The GetProcAddress stubs are at the moment merely enough to make this
link against Mesa 9.2, but should really be provided for everything not
in the OpenGL 1.2 ABI.

v2: Explicitly hide the GetProcAddress stubs so we can't conflict with
libGL symbols; fix leading tab/space issues [anholt]

10 years agoglx: Remove DRI1 AIGLX (v2)
Adam Jackson [Fri, 4 Oct 2013 16:58:19 +0000 (12:58 -0400)]
glx: Remove DRI1 AIGLX (v2)

Mesa doesn't ship DRI1 drivers as of 8.0, which is about 18 months and
three releases ago.  The main reason to have wanted DRI1 AIGLX was to
get a GLX compositor working, but DRI1's (lack of) memory management API
meant that the cost of a GLX compositor was breaking direct GLX apps,
which isn't a great tradeoff.

Of the DRI1 drivers Mesa has dropped, I believe only mga stands to lose
some functionality here, since it and only it has support for
NV_texture_rectangle.  Since that's required for every extant GLX
compositor I know of, I conclude that anybody with a savage, say, would
probably not notice AIGLX going away, since they wouldn't be running a
GLX compositor in the first place.

In the future we'd like to use GL in the server in a more natural way,
as just another EGL client, including in the GLX implementation itself.
Since there's no EGL implemented for DRI1 drivers, this would already
doom AIGLX on DRI1 (short of entirely forking the GLX implementation,
which I'm not enthusiastic about).

    Date:   Mon Mar 21 11:59:29 2011 -0400

glx: Reimplement context tags

In that, I changed the glx client state to not explicitly track the list
of current contexts for the client (since that was what we were deriving
tags from).  The bug was that I removed the code for same from
glxClientCallback without noticing that it had the side effect of
effectively de-currenting those contexts, so that ContextGone could free
them.  So, if you had a client exit with a context still current, the
context's memory would leak.  Not a huge deal for direct clients, but
viciously bad for indirect, since the swrast context state at the bottom
of Mesa is like 15M.

Fix this by promoting Bool isCurrent to ClientPtr currentClient, so that
we have a back-pointer to chase when walking the list of contexts when
ClientStateGone happens.

v2: Explicitly call __glXFreeContext on the ClientStateGone path.  Our
current context might be one we got from EXT_import_context and whose
creating client has since died.  Without the explicit call, the creating
client's FreeClientResources would not free the context because it's
still current, and the using client's FreeClientResources would not free
the context because it's not an XID it created.  This matches the logic
from a48dadc.

10 years agosync: always set the brackets (#59644)
Peter Hutterer [Wed, 16 Oct 2013 06:31:15 +0000 (16:31 +1000)]
sync: always set the brackets (#59644)

The current code sets bracket_greater to the first trigger after the current
value, and bracket_less to the last trigger before the current value.

For example, the idle timer with three negative and three positive transitions
would set this:

         nt1       nt2                 nt3
|--------|------|--|------- idle --|---|--|-----> t
               pt1                pt2    pt3
bracket_less == nt2
bracket_greater == pt2

This is an optimization so we can skip code paths in the block/wakeup handlers
if the current value doesn't meet any of the trigger requirements. Those
handlers largely do a
   if (bracket_less is less than current value &&
       bracket_greater is greater than current value)
        return, nothing to do

However, unless the bracket values are updated at the correct time, the
following may happen:

                                      nt
|--------------|---------- idle ------|--------> t
               pt

In this case, neither bracket is set, we're past the pos transition and not
yet at the neg transition. idle may now go past nt, but the brackets are not
updated. If idle is then reset to 0, no alarm is triggered for nt. Likewise,
idle may now go past pt and no alarm is triggered.

Changing an alarm or triggering an alarm will re-calculate the brackets, so
this bug is somewhat random. If any other client triggers an alarm when the
brackets are wrongly NULL, the recalculation will set them this bug may not
appear.

This patch changes the behavior, so that the brackets are always the nearest
positive or negative transitions to the current counter value. In the example
above, nt will trigger a wakeup and a re-calculation of the brackets, so that
going past it in the negative direction will then cause the proper alarm
triggers.

Or, in Keith's words:

  Timer currently past a positive trigger
      No bracket values, because no trigger in range

  Timer moves backwards before the positive trigger
      Brackets not reset, even though there is now a trigger in range

  Timer moves forward past the positive trigger
      Trigger doesn't fire because brackets not set

Setting the LT bracket in this case will cause everything to get
re-evaluated when the sync value moves backwards before the trigger
value.
