+Subject: [PATCH xf86-video-intel] SNA: fix PRIME output support since xserver
+ 1.20
+
+Since xorg-server 1.20, an external monitor would remain blank when used
+in a PRIME output slave setup. Only a cursor was visible. The cause is
+"Make PixmapDirtyUpdateRec::src a DrawablePtr" in xserver, the "src"
+pointer might point to the root window (created by the server) instead
+of a pixmap (as created by xf86-video-intel). Use get_drawable_pixmap to
+handle both cases.
+
+When built with -fsanitize=address, the following test will trigger a
+heap-buffer-overflow error due to to_sna_from_pixmap receiving a window
+instead of a pixmap.
+
+Test on a hybrid graphics laptop (Intel + modesetting/nouveau):
+
+    xrandr --setprovideroutputsource modesetting Intel
+    xrandr --output DP-1-1 --mode 2560x1440  # should not crash
+    glxgears  # should display gears on both screens
+
+Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=100086
+Signed-off-by: Peter Wu <peter@lekensteyn.nl>
+---
+Tested with xserver 1.20.1 with ASAN enabled. Survives multiple
+resolution changes, works with a Plasma desktop session, it seems
+stable. Something like this patch is required to make multi-monitor
+setups usable in a hybrid graphics setting with Xorg 1.20.
