2011-02-25drm/nv50-nvc0: request and wait on notification of modeset completionBen Skeggs
This should prevent a number of races from occuring, the most obvious of which will be exposed when we start making use of the "display sync" evo channel for page flipping. The DS channel will reject any command stream that doesn't completely agree with the current "master" state. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-02-25drm/nv50-nvc0: switch to tasklet for display isr bhBen Skeggs
We need to be able to have the bh run while possibly spinning waiting for the EVO notifier to signal. This apparently happens in some circumstances with preempt disabled, so our workqueue was never being run. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

More appropriate, and we're about to be using more than just the master EVO channel. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-02-25drm/nouveau: use system_wq instead of dev_priv->wqTejun Heo
With cmwq, there's no reason for nouveau to use a dedicated workqueue. Drop dev_priv->wq and use system_wq instead. Each work item is sync flushed when the containing structure is unregistered/destroyed. Note that this change also makes sure that nv50_gpio_handler is not freed while the contained work item is still running.

2010-12-03drm/nv50: rework PGPIO IRQ handling and hotplug detectionBen Skeggs
Allows callers to install their own handlers for when a GPIO line changes state (such as for hotplug detect). This also fixes a bug where we weren't acknowledging the GPIO IRQ until after the bottom half had run, causing a severe IRQ storm in some cases.

2010-12-03drm/nv50: Keep track of the head a channel is vsync'ing to.Francisco Jerez
In a multihead setup vblank interrupts may end up enabled in both heads. In that case we want to ignore the vblank interrupts coming from the wrong CRTC to avoid tearing and unbalanced calls to drm_vblank_get/put (fdo bug 31074).

2010-07-13drm/nouveau: add instmem flush() hookBen Skeggs
This removes the previous prepare_access() and finish_access() hooks, and replaces it with a much simpler flush() hook. All the chipset-specific code before nv50 has its use removed completely, as it's not required there at all. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-13drm/nv50: rewrite display irq handlerBen Skeggs
The previous handler basically worked correctly for a full-blown mode change. However, it did nothing at all when a partial (encoder only) reconfiguation was necessary, leading to the display hanging on certain types of mode switch. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-07-13drm/nouveau: tidy connector/encoder creation a littleBen Skeggs
Create connectors before encoders to avoid having to do another loop across encoder list whenever we create a new connector. This allows us to pass the connector to the encoder creation functions, and avoid using a create_resources() callback since we can now call it directly. This can also potentially modify the connector ordering on nv50. On cards where the DCB connector and encoder tables are in the same order, things will be unchanged. However, there's some cards where the ordering between the tables differ, and in one case, leads us to naming the connectors "wrongly". Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-04-09drm/nouveau: detect vram amount once, and save the valueBen Skeggs
As opposed to repeatedly reading the amount back from the GPU every time we need to know the VRAM size. We should now fail to load gracefully on detecting no VRAM, rather than something potentially messy happening. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-04-07drm/kms/fb: use slow work mechanism for normal hotplug also.Dave Airlie
a) slow work is always used now for any fbcon hotplug, as its not a fast task and is more suited to being ran under slow work. b) attempt to not do any fbdev changes when X is running as we'll just mess it up. This hooks set_par to hopefully do the changes once X hands control to fbdev. This also adds the nouveau/intel hotplug support. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-03-10drm/nv50: fix connector table parsing for some cardsBen Skeggs
The connector table index in the DCB entry for each output type is an index into the connector table, and does *not* necessarily match up with what was previously called "index" in the connector table entries themselves. Not real sure what that index is exactly, renamed to "index2" as we still use it to prevent creating multiple TV connectors. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

This makes this code common to both the nv04 and nv50 paths. For the moment, we keep the previous behaviour with HDMI/eDP connectors and report them as DVI-D/DP instead.
