| * | | | | | drm/i915: Override SDVO panel type in VBTChris Wilson2011-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Judging by comments in the BIOS, if the SDVO LVDS option h40 is enabled, then we are supposed to query the real panel type via Int15. We don't do this and so for the Sony Vaio VGC-JS210J which has otherwise default values, we choose the wrong mode. This patch adds a driver option, i915.vbt_sdvo_panel_type, which can be used to override the value in the VBT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of reporting EIO upfront in the entrance of an ioctl that may or may not attempt to use the GPU, defer the actual detection of an invalid ioctl to when we issue a GPU instruction.

This is much better than enabling/disabling self refresh for various reasons, including staying in a lower power state for more time and avoiding the need for cpu cycles. This was originally done manually to workaround issues with the hardware hanging. However, since 944001201: drm/i915: enable low power render writes on GEN3 hardware, automatic CxSR seems stable.

(We also suspect that the memory bus is clocked to the CPU/c-state and not the GPU so there are secondary starvation issues.) In order to prevent the most obvious issue of the low of the vblank interrupt (stuttering compositing that only updates when the mouse is moving) is to install a PM QoS request to prevent low c-states whilst the GPU is active.
