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. + +Signed-off-by: Dave Airlie +[hdegoede@redhat.com: Make configurable, fix with nvidia, submit upstream] +Signed-off-by: Hans de Goede +--- + hw/xfree86/common/xf86Config.c | 19 +++++++++++++++++++ + hw/xfree86/common/xf86Globals.c | 2 ++ + hw/xfree86/common/xf86Init.c | 20 ++++++++++++++++++++ + hw/xfree86/common/xf86Priv.h | 1 + + hw/xfree86/common/xf86Privstr.h | 1 + + hw/xfree86/common/xf86platformBus.c | 4 ++++ + hw/xfree86/man/Xorg.man | 7 +++++++ + hw/xfree86/man/xorg.conf.man | 6 ++++++ + randr/randrstr.h | 3 +++ + randr/rrprovider.c | 22 ++++++++++++++++++++++ + 10 files changed, 85 insertions(+) + +diff --git a/hw/xfree86/common/xf86Config.c b/hw/xfree86/common/xf86Config.c +index 2c1d335..d7d7c2e 100644 +--- a/hw/xfree86/common/xf86Config.c ++++ b/hw/xfree86/common/xf86Config.c +@@ -643,6 +643,7 @@ typedef enum { + FLAG_DRI2, + FLAG_USE_SIGIO, + FLAG_AUTO_ADD_GPU, ++ FLAG_AUTO_BIND_GPU, + FLAG_MAX_CLIENTS, + FLAG_IGLX, + FLAG_DEBUG, +@@ -699,6 +700,8 @@ static OptionInfoRec FlagOptions[] = { + {0}, FALSE}, + {FLAG_AUTO_ADD_GPU, "AutoAddGPU", OPTV_BOOLEAN, + {0}, FALSE}, ++ {FLAG_AUTO_BIND_GPU, "AutoBindGPU", OPTV_BOOLEAN, ++ {0}, FALSE}, + {FLAG_MAX_CLIENTS, "MaxClients", OPTV_INTEGER, + {0}, FALSE }, + {FLAG_IGLX, "IndirectGLX", OPTV_BOOLEAN, +@@ -779,6 +782,22 @@ configServerFlags(XF86ConfFlagsPtr flagsconf, XF86OptionPtr layoutopts) + } + xf86Msg(from, "%sutomatically adding GPU devices\n", + xf86Info.autoAddGPU ?
