2010-09-24drm/nouveau: we can't free ACPI EDID, so make a copy that we canBen Skeggs
The rest of the connector code assumes we can kfree() the EDID pointer. This causes things to blow up with the ACPI EDID pointer we get passed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nouveau: handle fifo pusher errors betterBen Skeggs
The most important part of this change is that we now instruct PFIFO to drop all pending fetches, rather than attempting to skip a single dword and hope that things would magically sort themselves out - they usually don't, and we end up with PFIFO being completely hung. This commit also adds somewhat more useful logging when these exceptions occur. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-09-24drm/nouveau: Try to fetch an EDID from OF if DDC fails.Francisco Jerez
More Apple brain damage, it fixes the modesetting failure on an eMac G4 (fdo bug 29810). Reported-by: Zoltan Varnagy <doi@freemail.hu> Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nouveau: Simplify tile region handling.Francisco Jerez
Instead of emptying the caches to avoid a race with the PFIFO puller, go straight ahead and try to recover from it when it happens. Also, kill pfifo->cache_flush and tile->lock, we don't need them anymore. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-09-24drm/nouveau: Don't enable AGP FW on nv18.Francisco Jerez

2010-09-24drm/nouveau: protect ramht_find() from oopsing if on channel without ramhtBen Skeggs
This doesn't actually happen now, but there's a test case for an earlier kernel where a GPU error is signalled on one of nv50's fake channels, and the ramht lookup by the IRQ handler triggered an oops. This adds a check for RAMHT's existance on a channel before looking up an object handle. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-09-24drm/nv40: Try to set up CRE_LCD even if it has unknown bits set.Francisco Jerez
They don't seem to do anything useful, and we really want to program CRE_LCD if we aren't lucky enough to find the right CRTC binding already set. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nv17-nv4x: Fix analog load detection false positive on rare occasions.Francisco Jerez
On some boards the residual current DAC outputs can draw when they're disconnected can be high enough to give a false load detection positive (I've only seen it in the S-video luma output of some cards, but just to be sure). The output line capacitance is limited and sampling twice should fix it reliably. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-09-24drm/nv20: Use the nv30 CRTC bandwidth calculation code.Francisco Jerez
nv2x CRTC FIFOs are as large as in nv3x (4kB it seems), and the FIFO control registers have the same layout: we can make them share the same implementation. Previously we were using the nv1x code, but the calculated FIFO watermarks are usually too low for nv2x and they cause horrible scanout artifacts. They've gone unnoticed until now because we've been leaving one of the bandwidth regs uninitialized (CRE 47, which contains the most significant bits of FFLWM), so everything seemed to work fine except in some cases after a cold boot, depending on the memory bandwidth and pixel clocks used.

2010-09-24drm/nouveau: Fix suspend on some nv4x AGP cards.Francisco Jerez
On some nv4x cards (specifically, the ones that use an internal PCIE->AGP bridge) the AGP controller state isn't preserved after a suspend/resume cycle, and the AGP control registers have moved from 0x18xx to 0x100xx, so the FW check in nouveau_mem_reset_agp() doesn't quite work. Check "dev->agp->mode" instead. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-09-14drm: Use a nondestructive mode for output detect when polling (v2)Chris Wilson
v2: Julien Cristau pointed out that @nondestructive results in double-negatives and confusion when trying to interpret the parameter, so use @force instead.

2010-09-13drm: Use a nondestructive mode for output detect when pollingChris Wilson
Destructive load-detection is very expensive and due to failings elsewhere can trigger system wide stalls of up to 600ms. A simple first step to correcting this is not to invoke such an expensive and destructive load-detection operation automatically.
