Enrico Weigelt, metux IT consult 61233adbca treewide: replace xnfreallocarray macro call by XNFreallocarray()
The xnfreallocarray was added along (and just as an alias to) XNFreallocarray
back a decade ago. It's just used in a few places and it's only saves us from
passing the first parameter (NULL), so the actual benefit isn't really huge.

No (known) driver is using it, so the macro can be dropped entirely.

Ville Syrjälä from Intel provides a method to calculate the preferred
clock and refresh rate from the existing resolution table and this
works for the issue.

v2. xf86ModeVRefresh might return 0, need to check it before use it.
v3. reported by Markus on launchpad that the issue is not devided by 0,
it's the "preferred" being accessed unconditionally.

Pedro Montes Alcalde 1bb6991bda AutoRepeat: Fix wrong repeat rate being applied
When you set the auto repeat rate trough xset to something like 250 40:
`xset r rate 250 40`
Is setting the first delay to 250ms and set the rate to 40hz (25ms)

However, if you were to apply this configuration from a xorg config file,
the result would be the first delay being applied correctly,
but the repeat rate would be set to 25Hz instead. This is because the config
option is using a rate of repeats per second but XKB stores it as interval.
Make sure this is converted correctly.

Peter Hutterer 412777664a Disallow byte-swapped clients by default
The X server swapping code is a huge attack surface, much of this code
is untested and prone to security issues. The use-case of byte-swapped
clients is very niche, so let's disable this by default and allow it
only when the respective config option or commandline flag is given.

For Xorg, this adds the ServerFlag "AllowByteSwappedClients" "on".
For all DDX, this adds the commandline options +byteswappedclients and
-byteswappedclients to enable or disable, respectively.

Sultan Alsawaf 07ad7a1138 xfree86: make xf86RotateCrtcRedisplay public
xf86RotateCrtcRedisplay() is about to be used outside of xf86Rotate.c in
order to copy transformed pixmaps, so fix up its interface by specifying
the source drawable and destination pixmap rather than assuming the root
drawable and rotated pixmap, respectively. In addition, add an argument to
make xf86RotateCrtcRedisplay() not perform any transformations, which is an
indicator that it should only copy a transformed pixmap rather than
actually transform a pixmap.

These changes make it possible to use xf86RotateCrtcRedisplay() to not
only copy transformed pixmaps, but also actually transform pixmaps, making
it very useful outside of xf86Rotate.c.

- Adds a few functions and fine-tunes the GPU hotplug infrastructure to allow
  the DDX driver to be loaded, if it is configured in the X config file
  options as "hotplug-driver".
- Scans and updates the PCI device list before adding the new GPU device
  in platform, so that the association of the platform device and PCI device
  is in place (dev->pdev).
- Adds documentation of this new option

An example usage in the config file would look like:

Section "OutputClass"
        Identifier "AMDgpu"
        MatchDriver "amdgpu"
        Driver "amdgpu"
	HotplugDriver "amdgpu"
EndSection

V2:
Fixed typo in commit message (Martin)
Added R-B from Adam.
Added ACK from Alex and Martin.

V3:

Jocelyn Falempe da9d012a9c xf86/logind: Fix drm_drop_master before vt_reldisp
When switching to VT, the ioctl DRM_DROP_MASTER must be done before
the ioctl VT_RELDISP. Otherwise the kernel can't change the modesetting
reliably, and this leads to the console not showing up in some cases, like
after unplugging a docking station with a DP or HDMI monitor.

Before doing the VT_RELDISP, send a dbus message to logind, to
pause the drm device, so logind will do the ioctl DRM_DROP_MASTER.

With this patch, it changes the order logind will send the resume
event, and drm will be sent last instead of first.
so there is a also fix to call systemd_logind_vtenter() at the right time.

Povilas Kanapickas 35af1299e7 Revert "hw/xfree86: Propagate physical dimensions from DRM connector"
Quite a lot of applications currently expect the screen DPI exposed by
the X server to be 96 even when the real display DPI is different.
Additionally, currently Xwayland completely ignores any hardware
information and sets the DPI to 96. Accordingly the new behavior, even
if it fixes a bug, should not be enabled automatically to all users.

A better solution would be to make the default DPI stay as is and enable
the correct behavior with a command line option (maybe -dpi auto, or
similar). For now let's just revert the bug fix.

luporl 7e142cb2a8 xserver: fix RGB mask handling
On FreeBSD 13.0-CURRENT for PowerPC64 big-endian (BE), X was
crashing in some cases. For instance, when twm was started
and the background was clicked to open its menu, X crashed
with a segmentation fault, trying to dereference a null pointer
at CreatePicture().

There were 2 issues with xorg-server handling of RGB masks that
caused the pointer above to be null and thus the crash:
- wrong use of ffs() to get the RGB offsets from the masks
- overflow when shifting a 16-bit integer

This change fixes both issues. They happen when the system is BE
but has a video adapter using a little-endian (LE) ARGB32
framebuffer. In order to display the correct colors, this setup
requires a BE RGBA32 color format to be used by X, by setting
the RGB masks appropriately, that didn't work properly because of
the issues above.

Jacob Cherry a5367face1 xfree86: Fix autoconfig secondary GPU devices
The code path added by commit 69e4b8e6 (xfree86: attempt to autoconfig
gpu slave devices (v3)) assumes that it will only be run if the primary
device on the screen is the first device in xf86configptr->conf_device_lst.
While this is true most of the time, there are two specific cases where
this assumption fails.

First, if the first device in conf_device_lst is assigned to a different
seat than the running X server, it will be skipped by the previous
FIND_SUITABLE macro usage. Second, if the primary device was explicitly
assigned to the screen but auto_gpu_device is still set and no secondary
devices were explicitly listed, that device may not be the first device
in conf_device_lst.

When the first device in conf_device_lst is not the primary device
assigned to the screen, two problems emerge. First, the first device in
conf_device_lst will never be assigned to the screen as a secondary
device. Second, the primary device is additionally assigned to the
screen as a secondary device. The combination of these problems causes
certain otherwise valid configurations to be invalid. For example, if a
primary device is assigned to a screen and a secondary device is listed
in the config but not explicitly assigned to the screen, then one order
of the device sections results in a usable PRIME or Reverse PRIME setup
and the other order does not.

This commit removes the assumption that the primary device is the first
device in conf_device_lst by starting the loop from the start of
conf_device_lst and skipping the primary device when it is encountered.

Olivier Fourdan b5e1f13681 dix: Add POINTER_RAWONLY flag
This add a new flag POINTER_RAWONLY for GetPointerEvents() which does
pretty much the opposite of POINTER_NORAW.

Basically, this tells GetPointerEvents() that we only want the
DeviceChanged events and any raw events for this motion but no actual
motion events.

This is preliminary work for Xwayland to be able to use relative motion
events for raw events. Xwayland would use absolute events for raw
events, but some X11 clients (wrongly) assume raw events to be always
relative.

To allow such clients to work with Xwayland, it needs to switch to
relative raw events (if those are available from the Wayland
compositor).

However, Xwayland cannot use relative motion events for actual pointer
location because that would cause a drift over time, the pointer being
actually controlled by the Wayland compositor.

So Xwayland needs to be able to send only relative raw events, hence
this API.

Bump the ABI_XINPUT_VERSION minor version to reflect that API addition.

v2: Actually avoid sending motion events (Peter)
v3: Keep sending raw emulated events with RAWONLY (Peter)

On the particular machine I was trying to set up an UDL device,
I found the following structure was being used to match
the device to a platform device while I was debugging the issue:

xf86_platform_devices[0] == Intel, /dev/dri/card1, primary platform device
xf86_platform_devices[1] == UDL, /dev/dri/card0

devList[0] == "Intel0", ZaphodHeads: DP1
devList[1] == "Intel1", ZaphodHeads: VGA1
devList[2] == "UDL"
devList[3] == "Intel2", ZaphodHeads: HDMI1 (intended GPU device to UDL)

When xf86platformProbeDev() matched the UDL device, the BusID
check failed in both cases of:
* BusID "usb:0:1.2:1.0" was specified
* Option "kmsdev" "/dev/dri/card0" was specified

As a result, xf86platformProbeDev() went on to call probeSingleDevice()
with xf86_platform_devices[0] and devList[2], resulting in the
UDL device being set up as a GPU device assigned to the first screen
instead of as a framebuffer on the third screen as the configuration
specified.

But the modesetting driver is actually part of the Xorg sources
instead of being an external driver, so he "kmsdev" path knowledge

Fabrice Fontaine 49456e0a37 hw/xfree86/common/xf86Init.c: fix build without glx
Since commit d8ec33fe05, an include on
glxvndabi.h has been added to hw/xfree86/common/xf86Init.c

However, if glx is disabled through --disable-glx and GLX headers are
not installed in the build's environment, build fails on:

In file included from xf86Init.c:81:
../../../include/glxvndabi.h:64:10: fatal error: GL/glxproto.h: No such file or directory
   64 | #include <GL/glxproto.h>
      |          ^~~~~~~~~~~~~~~

Fix this failure by removing this include which does not seem to be
needed (an other option would have been to keep it under an ifdef GLXEXT
block)

Kenneth Graunke 8d4be7f6c4 modesetting: Use EGL_MESA_query_driver to select DRI driver if possible
New now ask Glamor to use EGL_MESA_query_driver to obtain the DRI driver
name; if successful, we use that as the DRI driver name.  Following the
existing dri2.c logic, we also use the same name for the VDPAU driver,
except for i965 (and now iris), where we switch to the "va_gl" fallback.

This allows us to bypass the PCI ID lists in xserver and centralize the
driver selection mechanism inside Mesa.  The hope is that we no longer
have to update these lists for any future hardware.

Aaron Plattner e5e9a8ca91 xfree86: Call ScreenInit for protocol screens before GPU screens
During startup, the xfree86 DDX's InitOutput() calls PreInit for
protocol screens first, and then GPU screens. On teardown, dix_main()
calls CloseScreen in the reverse order: GPU screens first starting with
the last one and then working backwards, and then protocol screens also
in reverse order.

InitOutput() calls ScreenInit in the wrong order: for GPU screens first and then
for protocol screens. This causes a problem for drivers that have global state
that is tied to the first screen that calls ScreenInit.

Fix this by simply re-ordering the for loops to call PreInit for
protocol screens first and then for GPU screens second.

Dave Airlie 078277e4d9 xf86: autobind GPUs to the screen
This is a modified version of a patch we've been carry-ing in Fedora and
RHEL for years now. This patch automatically adds secondary GPUs to the
master as output sink / offload source making e.g. the use of
slave-outputs just work, with requiring the user to manually run
"xrandr --setprovideroutputsource" before he can hookup an external
monitor to his hybrid graphics laptop.

There is one problem with this patch, which is why it was not upstreamed
before. What to do when a secondary GPU gets detected really is a policy
decission (e.g. one may want to autobind PCI GPUs but not USB ones) and
as such should be under control of the Desktop Environment.

Unconditionally adding autobinding support to the xserver will result
in races between the DE dealing with the hotplug of a secondary GPU
and the server itself dealing with it.

However we've waited for years for any Desktop Environments to actually
start doing some sort of autoconfiguration of secondary GPUs and there
is still not a single DE dealing with this, so I believe that it is
time to upstream this now.

To avoid potential future problems if any DEs get support for doing
secondary GPU configuration themselves, the new autobind functionality
is made optional. Since no DEs currently support doing this themselves it
is enabled by default. When DEs grow support for doing this themselves
they can disable the servers autobinding through the servers cmdline or a
xorg.conf snippet.

Adam Jackson d791c8e5ab dga: Make shutdown less magical and/or terrifying
DGAShutdown() walks every screen and attempts to reset the mode.  That's
maybe a reasonable thing to do, although the explicit loop is certainly
a bad smell.

In ddxGiveUp it's called after we've torn down the vga arbiter - and in
fact most of the rest of screen state - which is... very very bad.  The
other place it's called is from the Control-Alt-BackSpace handler, where
we don't even attempt to do vga arb setup, and where in any case we're
going to escape the main loop eventually anyway.

Move all that cleanup work inside DGACloseScreen. This means it happens
earlier in server teardown than previously, but not in a way you're ever
going to be upset about.

Adam Jackson d8ec33fe05 glx: Use vnd layer for dispatch (v4)
The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.

Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.

v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.

The code used to be in xf86FormatPciBusNumber and compared parameter which was int, but since b967bf2a it was inlined now it works with uint8_t.

Adam Jackson dd00e5466a xfree86: Remove broken RANDR disabling logic (v4)
The only way to get at xf86Info.disableRandR from configuration is
Option "RANDR" "foo" in ServerFlags, which probably nobody is using
seeing as it's not documented. The other way it could be set is if a
screen supports RANDR 1.2, in which case we set it to avoid trying to
use the RANDR 1.1 compat code. If the second screen is not 1.2-aware
then this would mean we don't do RANDR setup on the second screen at
all, which would almost certainly crash the first time you try to do
RANDR operations on the second screen.

Fix that all by deletion, and just check whether the screen already has
RANDR initialized before installing the stub support. If you want to
disable RANDR, use the Extensions section of xorg.conf instead.

v2: Also remove a now entirely pointless log message, telling you to
ignore a line we will no longer print.

v3: Explain the fallback path in InitOutput. (Keith Packard)

v4: Check whether the RANDR private key is initialized before trying to
use it to look up the screen private.

Adam Jackson 5cb330cd5d Revert "xfree86: Remove broken RANDR disabling logic (v3)"
Tsk. This broke vesa for me, the rrGetScrPriv in InitOutput will crash
if randr's screen private key hasn't been initialized yet. That seems
dumb, but let's not leave it broken.

This reverts commit c08d7c1cdd.

Martin Wilck a5e9bcad7a xfree86: add default modes for 16:9 and 16:10
Improve the user experience for users with wide screens by adding standard
16:9 and 16:10 modes to extramodes, as suggested previously
(https://lists.x.org/archives/xorg-devel/2016-February/048866.html).
Tested successfully on my laptop. Feedback welcome.

Adam Jackson 0a255dceb7 xfree86: Remove xf86InterceptSignals
The only consumer of this is the Linux vm86 backend for int10 (which you
should not use), and there all it serves to do is make signals generated
by the vm86 task non-fatal. In practice this error appears never to
happen, and marching ahead with root privileges after arbitrary code has
raised a signal seems like a poor plan.

Remove the usage in the vm86 code, making this error fatal.

Adam Jackson 722c8035dc xfree86: Remove xf86InterceptSigIll
This was added in ~2004 for the sis driver, to detect whether it could
use SSE for memcpy. Charmingly, the code to check whether that feature
exists in the server is:

    #if XORG_VERSION_CURRENT >= XORG_VERSION_NUMERIC(6,8,99,13,0)
    #define SISCHECKOSSSE           /* Automatic check OS for SSE; requires SigIll facility */
    #endif

Which means it has never worked in any modular server release.

A less gross way to do this is to check for SSE support with getauxval()
or /proc/cpuinfo or similar. Since no driver is using the existing
intercept mechanism, drop it.
