From f89458722173b364b8c3c27788b6c61889da554c Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Fri, 18 May 2007 09:40:01 -0700 Subject: Add locking. The main lock is dev->mode_config.config_lock. It should be held across any operations that modify mode lists, crtc config, output config, etc. It should be taken at high level entry points (currently just initial config and user IOCTL). Seems to work ok on my system, but needs more testing (with lockdep) and review from some fresh eyes. --- linux-core/intel_fb.c | 1 + 1 file changed, 1 insertion(+) (limited to 'linux-core/intel_fb.c') diff --git a/linux-core/intel_fb.c b/linux-core/intel_fb.c index 7126c16c..2ce66460 100644 --- a/linux-core/intel_fb.c +++ b/linux-core/intel_fb.c @@ -203,6 +203,7 @@ static int intelfb_check_var(struct fb_var_screeninfo *var, } /* this will let fbcon do the mode init */ +/* FIXME: take mode config lock? */ static int intelfb_set_par(struct fb_info *info) { struct intelfb_par *par = info->par; -- cgit v1.2.3
