From d5627663f2088fa4be447fdcfd52bcb233448d85 Mon Sep 17 00:00:00 2001 From: Mathew McKernan Date: Tue, 12 Apr 2011 06:51:37 +0100 Subject: drm/i915/tv: Remember the detected TV type During detect() we would probe the connection bits to determine if there was a TV attached, and what video input type (Component, S-Video, Composite, etc) to use. However, we promptly discarded this vital bit of information and never propagated it to where it was used to determine the correct modes and setup the control registers. Fix it! This fixes a regression from 7b334fcb45b757ffb093696ca3de1b0c8b4a33f1.

This caused the screen to quickly turn off before returning whenever modesetting/mode probing took place on my 915GM EeePC 900 creating a flickering effect. This patch changes intel_crtc->pipe back to intel_crtc->plane which solves the problem for me.

The example reported by Seth Forshee is very similar to the bug we encountered with the state left by grub2, that the crtc pipe<->planning mapping was reversed from our expectations and so we failed to turn off the outputs when booting or, in this case, resuming. This may be in fact the same bug, but triggered at resume time. This patch rearranges the code we already have to clear up the conflicting state upon init and calls it from reset (which is called after we have lost control of the hardware, i.e. along both the boot and resume paths) instead.

If i2c fails, add the connector to the user can at least force it on. Note that some distros set i2c-algo-bit.bit_test to 1 by default which sometimes fails preventing the ddc i2c adapter from being added. The i2c adapter works even if the bit test fails, probably due to pre/post_xfer not getting called in the test_bit function. I have another patch to follow up on that.

The Xen changes were using DMA_ERROR_CODE which isn't defined on a few platforms, however we reverted the Xen patch that caused use to try and use this code path earlier in 2.6.39 cycle, so for now lets just force the code to never take this path and allow it to build again on alpha. The proper long term answer is probably to store if the dma_addr has been assigned to alongside the dma_addr in the higher level code, though I think Thomas wanted to rewrite most of this anyways properly.
