At least the worst offenders: - SDVO specifies that the encoder should compute the ecc. Testing also shows that we must not send the ecc field, so copy the dip_infoframe struct to a temporay place and avoid the ecc field. This way the avi infoframe is exactly 17 bytes long, which agrees with what the spec mandates as a minimal storage capacity (with the ecc field it would be 18 bytes). - Only 17 when sending the avi infoframe. The SDVO spec explicitly says that sending more data than what the device announces results in undefined behaviour. - Add __attribute__((packed)) to the avi and spd infoframes, for otherwise they're wrongly aligned. Noticed because the avi infoframe ended up being 18 bytes large instead of 17. We haven't noticed this yet because we don't use the uint16_t fields yet (which are the only ones that would be wrongly aligned).

Hidden away within one chipset specific path was the necessary logic to turn on the PLL. This needs to be done everywhere in order for us to drive any display! As such as soon as we tested on a non-CougarPoint chipset, we failed to bring up any DisplayPorts and generated a nice set of assertion failures in the process. At least one part of our logic is working, the part that assumes that we have no idea what we are doing.

In many places we wish to iterate over the rings associated with the GPU, so refactor them to use a common macro. Along the way, there are a few code removals that should be side-effect free and some rearrangement which should only have a cosmetic impact, such as error-state. Note that this slightly changes the semantics in the hangcheck code: We now always cycle through all enabled rings instead of short-circuiting the logic. v2: Pull in a couple of suggestions from Ben and Daniel for intel_ring_initialized() and not removing the warning (just moving them to a new home, closer to the error).

On Haswell, we need to properly train the DDI buffers prior to enabling HDMI, and enable the required clocks with correct dividers for the desired frequency. Also, we cannot simple reuse HDMI routines from previous generations of GPU, as most of HDMI-specific stuff is being done via the DDI port programming instead of HDMI-specific registers. This commit take advantage of the WR PLL clock table which is in a separate (previous) commit to select the right divisors for each mode.

Digital port detection on Haswell is indicated by the presence of a bit in DDI_BUF_CTL for port A, and by a different register for ports B, C and D. So we check for those bits during the initialization time and let the hdmi function know about those. Note that this bit does not indicates whether the output is DP or HDMI. However, the DDI buffers can be programmed in a way that is shared between DP/HDMI and FDI/HDMI except for PORT E. So for now, we detect those digital outputs as being HDMI, but proper DP support is still pending. Note that DDI A can only drive eDP, so we do not handle it here for hdmi initialization. v2: simplify Haswell handling logic v3: use generic function for handling digital outputs.

DDI is introduced starting with Haswell GPU generation. So to simplify its management in the future, we also add intel_ddi.c to hold all the DDI-related items. Buffer translations for DDI links must be initialized prior to enablement. For FDI and DP, first 9 pairs of values are used to select the connection parameters. HDMI uses the last pair of values and ignores the first 9 pairs. So we program HDMI values in both cases, which allows HDMI to work over both FDI and DP-friendly buffers.

Prevent bogus asserts on DDI-related paths. Longer explanation from Eugeni by mail: "For the asserts there are 3 paths where we hit them: - in assert_fdi_tx (we don't have the FDI_TX_CTL anymore, backup plan DDI_FUNC_CTL is used instead) - in assert_fdi_tx_pll_enabled (we have the combination of iCLKIP and DDI_FUNC_CTL, plus PORT_CLK_SEL and PIPE_CLK_SEL now to make things work). We could use an assert here indeed - if we configure port to use one clock, and pipe to use another, everything hangs. Right now, we configure all of them in one place only; but yes, when DP code lands it will get more funky. - and in ironlake_fdi_pll_enable. I reuse part of this function (to configure the TU sizes), but as in the 1st case, FDI_TX_CTL is gone so I just ignore it here."
