It can help to remove any ambiguity about which options were passed to Nouveau, especially in case the user had some options set in /etc/modprobe.d/*.conf that he forgot about, as they won't appear in a dmesg.

2014-09-15drm/nouveau/pwr: fix the timers implementation with concurent processesMartin Peres5-990/+1133
The problem with the current implementation is that adding a timer improperly checked which process would time up first by not taking into account how much time elapsed since their timer got scheduled. Rework the re-scheduling decision t fix this. The catch with this fix is that we are limited to scheduling timers of up to 2^31 ticks to avoid any potential overflow. Since we are unlikely to need to wait for more than a second, this won't be a problem :) Another possible fix would be to decrement the timeouts of all processes but it would duplicate a lot of code and dealing with edge cases wasn't pretty last time I checked.

2014-09-15drm/nouveau/core/mm: fill in holes with "allocated" nodesBen Skeggs2-6/+21
The allocation algorithm doesn't expect there to be holes in the mm, which causes its alignment/cutoff calculations to choke (and go negative) when encountering the last chunk of a block before a hole. The least expensive solution is to simply fill in any holes with nodes that are pre-marked as being allocated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-09-15drm: Drop modeset locking from crtc init functionDaniel Vetter1-5/+0
At driver init no one can access modeset objects and we're single-threaded. So locking is just cargo-culting here. Worse, with the new ww mutexes and ww mutex slowpath debugging the mutex_lock might actually fail, and we don't have the full-blown ww recovery dance. Which then leads to fireworks when we try to unlock the not-locked crtc lock. An audit of all the functions called from here shows that none of them contain locking checks, so there's also no reason to keep the locking around just for consistency of caller contexts. Besides that I have the rule (at least in i915) that such places where we take locks just to simplify locking checks and not for correctness always require a comment. This regression was introduced in commit 51fd371bbaf94018a1223b4e2cf20b9880fd92d4 Author: Rob Clark <robdclark@gmail.com> Date: Tue Nov 19 12:10:12 2013 -0500 drm: convert crtc and connection_mutex to ww_mutex (v5) v2: Don't drop the lock_init call, spotted by the 0day builder.

2014-09-15drm/edid: Reduce horizontal timings for pixel replicated modesClint Taylor1-48/+48
Pixel replicated modes should be non-2x horizontal timings and pixel replicated by the HW across the HDMI cable at 2X pixel clock. Current horizontal resolution of 1440 does not allow pixel duplication to occur and scaling artifacts occur on the TV. HDMI certification 7-26 currently fails for all pixel replicated modes. This change will allow HDMI certification with 480i/576i modes once pixel replication is turned on.

Showing who is the current master is useful for trying to decypher errors when trying to acquire master (e.g. a race with X taking over from plymouth).

2014-09-15drm/ast: Don't assume DVO enabled means SIL164 on uninitialized chipsBenjamin Herrenschmidt1-4/+10
It looks like the AST2400 comes up with the DVO enable bit set, which causes us to incorrectly assume we have a SIL164 regardless of the value of the scratch registers setup by the BMC firmware. So let's limit that test to the case where the chip has already been setup by a BIOS. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2014-09-15drm/ast: Properly initialize P2A base before using it in ast_init_3rdtx()Benjamin Herrenschmidt1-0/+11
If the P2A has been used to target other SOC registers before that call, we're going to hit the wrong place so make sure we set the base address up properly before using it. (P2A stands for PCIe to AHB bridge and is the bride that allows accessing the AST's internal AHB bus using a relocatable 64k window in the second half of the PCIe MMIO BAR) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2014-09-15drm/ast: POST chip at probe time if VGA not enabledBenjamin Herrenschmidt3-11/+62
We need to do it on machines without a BIOS such as POWER8. Also for detection to work without triggering PCIe errors, we need to enable VGA early on, inside ast_detect_chip().
