HAS_PCH_SPLIT() is the most radical change across chipsets, so it seems like a natural split to simplify the code. This first commit just copies the existing code without changing anything. v2: updated to track removal of call to intel_enable_plane from i9xx_crtc_mode_set Signed-off-by: Eric Anholt <eric@anholt.net> Hella-acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Otherwise, the display engine may read through an invalid PTE and so throw an PGTBL_ER exception. As we need to perform load detection before even the first object is allocated for the fbdev, there is no pre-existing object large enough for us to borrow to use as the framebuffer. So we need to create one and cleanup afterwards. At other times, the current fbcon may be large enough for us to borrow it for duration of load detection. Found by assert_fb_bound_for_plane().

This means VGA arbitration on those GPUs can be controlled by using the bridge routing instead of io/mem decodes. The problem is locating which GPUs share which upstream bridges. This patch attempts to identify all the GPUs which can be controlled via bridges, and ones that can't. This patch endeavours to work out the bridge sharing semantics. When disabling GPUs via a bridge, it doesn't do irq callbacks or touch the io/mem decodes for the gpu. Signed-off-by: Dave Airlie <airlied@redhat.com>

If it turns out that the device has no useable path we schedule the deregistration of the device (which is still in an non-final state) and wake up the waiting process. The deregistration process will set a final state, but if the wake up happens to be prior to this, the device will hang forever in ccw_device_set_online. To fix this just set the final NOT_OPER state prior to the scheduled deregistration of the device.
