From 70e5766874a919039678bb2ed75f2ccea0cb4345 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 27 Aug 2012 15:22:44 +1000 Subject: [PATCH] xf86: fix multi-seat video device support. (v2) If we are not seat 0 the following apply: don't probe any bus other than platform don't probe any drivers other than platform assume the first platform device we match on the bus is the primary GPU. This just adds checks in the correct places to ensure this, and with this X can now start on a secondary seat for an output device. v2: fix Seat0 macros Reviewed-by: Keith Packard Signed-off-by: Dave Airlie --- hw/xfree86/common/xf86Bus.c | 4 ++++ hw/xfree86/common/xf86platformBus.c | 3 +++ 2 files changed, 7 insertions(+) diff --git a/hw/xfree86/common/xf86Bus.c b/hw/xfree86/common/xf86Bus.c index 6de8409fc..4ffbf7e46 100644 --- a/hw/xfree86/common/xf86Bus.c +++ b/hw/xfree86/common/xf86Bus.c @@ -81,6 +81,8 @@ xf86CallDriverProbe(DriverPtr drv, Bool detect_only) if (drv->platformProbe != NULL) { foundScreen = xf86platformProbeDev(drv); } + if (ServerIsNotSeat0()) + return foundScreen; #endif #ifdef XSERVER_LIBPCIACCESS @@ -214,6 +216,8 @@ xf86BusProbe(void) { #ifdef XSERVER_PLATFORM_BUS xf86platformProbe(); + if (ServerIsNotSeat0()) + return; #endif #ifdef XSERVER_LIBPCIACCESS xf86PciProbe(); diff --git a/hw/xfree86/common/xf86platformBus.c b/hw/xfree86/common/xf86platformBus.c index 6a8fb907a..0525e39bc 100644 --- a/hw/xfree86/common/xf86platformBus.c +++ b/hw/xfree86/common/xf86platformBus.c @@ -359,6 +359,9 @@ xf86platformProbeDev(DriverPtr drvp) break; } else { + /* for non-seat0 servers assume first device is the master */ + if (ServerIsNotSeat0()) + break; if (xf86_platform_devices[j].pdev) { if (xf86IsPrimaryPlatform(&xf86_platform_devices[j])) break;
