2016-03-25tools/cursor: Print an ASCII representation as wellChris Wilson
Show the ASCII outline of the cursor as well as the image stored in the PNG. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-08intel-virtual-output: Virtual heads are numbered from index 1Chris Wilson
When checking for VIRTUAL support on the xserver, it helps to check for the right name. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-06intel-virtual-output: Print more helpful error when run on the wrong serverChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-04tools/intel-virtual-output: Propagate screen blankingChris Wilson
When attaching to a target display, disable the builtin screen blanking (equivalent to xset -d :8 s off, or setting Option "BlankTime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" in the target xorg.conf). Then listen to the ScreenSaver notify events on the host and forward the activations/resets to the targets. This should then keep all the screen blanking in sync. Reported-by: Raffael Herzog <herzog@raffael.ch> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93562 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-03tools/intel-virtual-output: Respond to expose events on target displaysChris Wilson
If the destination screen is exposed (for example screensavers), we need to redraw. So enable the ExposeEvent on the target and synthesize damage to any clones on that display in order to trigger a redraw.

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-06-03intel-virtual-output: Fix cloning fixed mode outputsChris Wilson
When using a fixed mode, e.g. a Display without RandR support like Xnest, we have to remember to hook up the connection during recofiguration of VIRTUAL outputs. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-05-16intel-virtual-output: Record the cursor shape in the DBG logChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-05-16intel-virtual-output: Only store cursor image on reference displayChris Wilson
We only need a single copy of the cursor image, from which we can create all the cloned cursors. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-04-21tools/dri3info: Include compilation instructions for standalone buildingChris Wilson
Let the read know how to compile dri3info without having to compile the whole of xf86-video-intel Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-04-09tools/intel-virtual-output: Update DBG comment to include DRI3 transportChris Wilson
The Pixmap may either be being used for DRI3 or SHM transport. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-04-01configure: Make tools/PROGRAMS agnostic to tools presenceChris Wilson
In order to make tools indivdiually selectable for compiling, we don't want to override earlier tools - so use '+=' rather than a plain '=' when adding each tool to the set of PROGRAMS. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-03-25Use AC_HEADER_MAJOR to find how to include major()Chris Wilson
We need to include <sys/mkdev.h> on Solaris. Reported-by: Richard Palo <richard@netbsd.org> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89763 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-03-06tools/cursor: Inlcude stdlib for malloc declarationChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-03-04tools: Add simple tool to retrieve the current cursor from XChris Wilson
Slightly more funky would be to poke around in the CRTC, but that should require master. As it stands this should help verify that what X is supplying to the driver matches user expectations Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-02-25tools/intel-virtual-output: Use xcb_dri3_idChris Wilson
xcb exports the extension structs for querying whether they exist and sharing the results. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-02-16tools/intel-virtual-output: Check for DRI3 more carefullyChris Wilson
Using xcb, we cannot simply call xcb_dri3_query_version() without it terminating the connection if DRI3 is not enabled on the target display. Oops. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89172 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-02-09tools: Add rudimentary dri3infoChris Wilson
A simple tool just to check if the target Xserver offers dri3. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-12-17intel-virtual-output: Do not attempt to tidy up the local display if it failsChris Wilson
Just fix the segfault dereferencing the primary display if we bail during its setup. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-08-27intel-virtual-output: Use snprintf() for simplicityChris Wilson
Third one-line patch to fix copying from the tainted user argument into the socket's path buffer. This time, give in and just use snprintf() as it guarrantees that it will not write more than 'n' characters and that the last is a NUL byte. Suggested-by: Zdenek Kabelac <zkabelac@redhat.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-08-26intel-virtual-output: Fix invocation of strncpy()Chris Wilson
Somebody (me) confused it with snprintf() and put the string length in the wrong location. Also note that strncpy() does not NUL terminate long strings. Reported-by: Zdenek Kabelac <zdenek.kabelac@gmail.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-07-18configure: Double check xinerama's headersChris Wilson
Having the pkgconfig present doesn't always necessarily imply the headers are installed correctly - just fail over gracefully for xinerama and intel-virtual-output Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-07-17backlight: Prevent dereference of potential NULL argvChris Wilson
Adam Sampson spotted that "It's possible (but not very sensible) to exec a program with an empty argument list, so argv[0] is not necessarily a valid pointer. For example: $ cat exec0.c int main(int argc, char *argv[]) { char *empty[1] = { NULL }; execvp(argv[1], empty); perror("execvp"); return 1; } $ ./exec0 /usr/libexec/xf86-video-intel-backlight-helper Usage: (null) <iface> " He sensibly suggested that we hardcode the program name to avoid the NULL dereference. Being the paranoid type, we should also be careful not to write to any file descriptors outside of our control (i.e. stderr), so disable the messages unless we are debugging.

2014-07-04backlight: Fix security issues in handling of the interface path name.Matthieu Herrb

2014-06-29intel-virtual-output: Convert debugging messages to verbosityChris Wilson
Original patch by main.haarp: "A verbose switch is quite useful for debugging, it shouldn't require editing and recompilation to gain more useful output. I added it." Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=80664 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-05-16intel-virtual-output: Mark the source SHMPixmap as writeableChris Wilson
