Alan Coopersmith 0ba7fc8472 Stop including inline assembly .il file for Solaris Studio builds
Since all the inb/outb/etc. use in the X server itself (except for
xf86SlowBcopy) has been replaced by calls to libpciaccess, we no
longer need to pass inline assembly files to replace the gcc inline
assembly from hw/xfree86/common/compiler.h when building Xorg itself.

The .il files are still generated and installed in the SDK for the
benefit of drivers who may use them.

Binary diff of before and after showed that xf86SlowBcopy was the
only function changed across the Xorg binary and all modules built
in the Xserver build, it just calls the outb() function now instead
of having the outb instructions inlined, making it a slightly slower
bcopy.

<stdlib.h> and other core headers start including <sys/regset.h>, which
has a bunch of unfortunately named macros such as "CS", "ES", etc. for
x86 & x64 registers which clash with existing variable & struct member
names in Xorg - so #undef these so they don't interfere with our use.

(Yes, have filed a bug against the system headers for exposing these,
 but this solves the problem for building on existing releases.)

Adam Jackson 8aacf47e17 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).

Gaetan Nadon 35a528e492 Xorg binary: use install-exec-hook rather than install-exec-local
The former was explicitly designed to execute additional code after the binary
has been installed. The latter can be executed in any order, hence it's
current dependency on install-binPROGRAMS as a workaround.

The CYGWIN libXorg.exe.a target is an installation target rather than
a post-installation one, so it should not be done as a hook. It does not depend
on the Xorg executable being installed.

Automake:
"These hooks are run after all other install rules of the appropriate type,
exec or data, have completed. So, for instance, it is possible to perform
post-installation modifications using an install hook".

"With the -local targets, there is no particular guarantee of execution order;
typically, they are run early, but with parallel make, there is no way
to be sure of that".

Aaron Plattner bdd1e22cbd xfree86: detach scanout pixmaps when detaching output GPUs
Commit 8f4640bdb9 fixed a bit of a
chicken-and-egg problem by detaching GPU screens when their providers
are destroyed, which happens before CloseScreen is called.  However,
this created a new problem: the GPU screen tears down its RandR crtc
objects during CloseScreen and if one of them is active, it tries to
detach the scanout pixmap then.  This crashes because
RRCrtcDetachScanoutPixmap tries to get the master screen's screen
pixmap, but crtc->pScreen->current_master is already NULL at that
point.

It doesn't make sense for an unbound GPU screen to still be scanning
out its former master screen's pixmap, so detach them first when the
provider is destroyed.

Peter Hutterer 21ea7ebb6a dix: scale y back instead of x up when pre-scaling coordinates
The peculiar way we handle coordinates results in relative coordinates on
absolute devices being added to the last value, then that value is mapped to
the screen (taking the device dimensions into account). From that mapped
value we get the final coordinates, both screen and device coordinates.

To avoid uneven scaling on relative coordinates, they are pre-scaled by
screen ratio:resolution:device ratio factor before being mapped. This
ensures that a circle drawn on the device is a circle on the screen.

Previously, we used the ratio to scale x up. Synaptics already does its own
scaling based on the resolution and that is done by scaling y down by the
ratio. So we can remove the code from the driver and get approximately the
same behaviour here.

Minor ABI bump, so we can remove this from synaptics.

Eric Anholt 77e51d5bbb Revert "DRI2: re-allocate DRI2 drawable if pixmap serial changes"
This reverts commit 3209b094a3.  After a
long debug session by Paul Berry, it appears that this was the commit
that has been producing sporadic failures in piglit front buffer
rendering tests for the last several years.

GetBuffers may return fresh buffers with invalid contents at a couple
reasonable times:

- When first asked for a non-fake-front buffer.
- When the drawable size is changed, an Invalidate has been sent, and
  obviously the app needs to redraw the whole buffer.
- After a glXSwapBuffers(), GL allows the backbuffer to be undefined,
  and an Invalidate was sent to tell the GL that it should grab these
  appropriate new buffers to avoid stalling.

But with the patch being reverted, GetBuffers would also return fresh
invalid buffers when the drawable serial number changed, which is
approximately "whenever, for any reason".  The app is not expecting
invalid buffer contents "whenever", nor is it valid.  Because the GL
usually only GetBuffers after an Invalidate is sent, and the new
buffer allocation only happened during a GetBuffers, most apps saw no
problems.  But apps that do (fake-)frontbuffer rendering do frequently
ask the server for the front buffer (since we drop the fake front
allocation when we're not doing front buffer rendering), and if the
drawable serial got bumped midway through a draw, the server would
pointlessly ditch the front *and* backbuffer full of important
drawing, resulting in bad rendering.

The patch was originally to fix bugzilla:
https://bugs.freedesktop.org/show_bug.cgi?id=28365
Specifically:

    To reproduce, start with a large-ish display (i.e. 1680x1050 on my
    laptop), use the patched glxgears from bug 28252 to add the
    -override option.  Then run glxgears -override -geometry 640x480
    to create a 640x480 window in the top left corner, which will work
    fine.  Next, run xrandr -s 640x480 and watch the fireworks.

I've tested with an override-redirect glxgears, both with vblank sync
enabled and disabled, both with gnome-shell and no window manager at
all, before and after this patch.  The only problem observed was that
before and after the revert, sometimes when alt-tabbing to kill my
gears after completing the test gnome-shell would get confused about
override-redirectness of the glxgears window (according to a log
message) and apparently not bother doing any further compositing.

So in the cold plug server shutdown case, we reap the resources

is a dangling pointer when the xf86CrtcCloseScreen handler is called,

however in the hot screen unplug case, we can't rely on automatically
reaped resources, so we need to clean up the provider in the xf86CrtcCloseScreen
case.

This patch provides a cleanup callback from the randr provider removal
into the DDX so it can cleanup properly, this then gets called by the automatic
code for cold plug, or if hot unplug it gets called explicitly.

Peter Hutterer 9f79e93b6b Short-cut the input device cleanup process during AbortServer()
If we're about to abort, we're already in the signal handler and cannot call
down to the default device cleanup routines (which reset, free, alloc, and
do a bunch of other things).

Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
reset the hardware if needed but do nothing else. An actual HW reset is only
required for some drivers dealing with the HW directly.

This is largely backwards-compatible, hence the input ABI minor bump only.

Drivers we care about either return BadValue on a mode that's not
DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
here is vmmouse, which currently ignores it and would not reset anything.
This should be fixed if the reset is required.

Alan Coopersmith c1c01e3508 Make xf86ValidateModes actually copy clock range list to screen pointer
Our in-house parfait 1.1 code analysis tool complained that every exit
path from xf86ValidateModes() in hw/xfree86/common/xf86Mode.c leaks the
storeClockRanges allocation made at line 1501 with XNFalloc.

Investigating, it seems that this code to copy the clock range list to
the clockRanges list in the screen pointer is just plain insane, and
according to git, has been since we first imported it from XFree86.

We start at line 1495 by walking the linked list from scrp->clockRanges
until we find the end.  But that was just a diversion, since we've found
the end and immediately forgotten it, and thus at 1499 we know that
storeClockRanges is NULL, but that's not a problem since we're going to
immediately overwrite that value as the first thing in the loop.

So we move on through this loop at 1499, which takes us through the
linked list from the clockRanges variable, and for every entry in
that list allocates a new structure and copies cp to it.  If we've
not filled in the screen's clockRanges pointer yet, we set it to
the first storeClockRanges we copied from cp.   Otherwise, as best
I can tell, we just drop it into memory and let it leak away, as
parfait warned.

And then we hit the loop action, which if we haven't hit the end of
the cp list, advances cp to the next item in the list, and then just
for the fun of it, also sets storeClockRanges to the ->next pointer it
has just copied from cp as well, even though it's going to overwrite
it as the very first instruction in the loop body.

Peter Hutterer ad3bc57134 xfree86: update the device state for all DGA events (#59100)
DGA only handles master devices but it does intercept slave device events as
well (since the event handlers are per event type, not per device).

The DGA code must thus call into UpdateDeviceState to reset the button/key
state on the slave device before it discards the remainder of the event.

Test case:
- Passive GrabModeSync on VCP
- Press button
- Enable DGA after ButtonPress
- AllowEvents(SyncPointer)
- Release button

The button release is handled by DGAProcessPointerEvent but the device state
is never updated, so the slave ends up with the button permanently down.
And since the master's button state is the union of the slave states, the
master has the button permanently down.

Stephan Schreiber 36c18bb81b int10: fix pci_device_read_rom usage
I noticed that the build-in int10 driver always reports
"Unable to retrieve all of segment 0x0C0000."
even though the entire BIOS data is retrieved with success.

The associated code is in hw/xfree86/int10/generic.c, in the function
xf86ExtendedInitInt10():

    if (pci_device_read_rom(pInt->dev, vbiosMem) < V_BIOS_SIZE) {
        xf86DrvMsg(screen, X_WARNING,
                   "Unable to retrieve all of segment 0x0C0000.\n");
    }

The function pci_device_read_rom() is from libpciaccess; its return
value is not a size but an error status code: 0 means success.
If pci_device_read_rom() returns 0 for success, the warning is generated.

The proposed patch corrects the evaluation of the return value of
pci_device_read_rom() and of the supplied BIOS size.

Adam Jackson 245e7e0361 xfree86: Change the semantics of driverFunc(GET_REQUIRED_HW_INTERFACES)
This is a really awkward interface, since we're calling it well before
the driver knows what device it's going to drive.  Drivers with both KMS
and UMS support therefore don't know whether to say they need I/O port
access or not, and have to assume they do.

With this change we now call it only to query whether port access might
be needed; we don't use that to determine whether to call a driver's
probe function or not, instead we call them unconditionally.  If the
driver doesn't check whether port access was enabled, they might crash
ungracefully.  To accomodate this, we move xorgHWAccess to be explicitly
intentionally exported (sigh xf86Priv.h) so that drivers can check that
before they attempt port access.

v2: Move initial xf86EnableIO() nearer the logic that determines whether
to call it, suggested by Simon Farnsworth.

Dave Airlie 20f601a0fb xf86/crtc: don't free config->name
This is set by pre_init not screen init, so if we free it here
and then recycle the server, we lose all the providers.

I think we need to wrap FreeScreen here to do this properly,
will investigate for 1.14 most likely, safer to just leak this
on server exit for now.

Aaron Plattner 3e091e1075 xfree86: Bump extension ABI to 7.0
Commit 9d457f9c55 added an array of
DevPrivateSetRec structures in the middle of the ScreenRec, which throws off
extension modules trying to call things like pScreen->DestroyPixmap.

Keith Packard c0540b4c8d Kludge -- Call RandR screen before cleaning up xf86 crtcs
The core RandR screen cleanup now involves cleaning up any GPU screen
associations, and those call down into DDX to clean up the driver. If
the pointers from the xf86 structures back to the core randr
structures are set to NULL at that point, bad things happen.

This patch "knows" that the core RandR close screen is underneath the
xf86 randr close screen function, and so makes sure it gets called
first.
