If the table result is out of bounds on the array map there is something really wrong with VBT pin so we don't return that vbt_pin, but only return 0 instead. This basically reverts commit 'a8e6f388 ("drm/i915/cnp: Ignore VBT request for know invalid DDC pin.")' Also this properly fixes commit 9c3b2689 ("drm/i915/cnl: Map VBT DDC Pin to BSpec DDC Pin.") v2: Do in a way that we don't break other platforms. (Jani) v3: Keep debug message (Jani) v4: Don't mess with 0 mapping was noticed by Jani and addressed with a simple solution suggested by Lucas that makes this even simpler.

We parse and store the child devices in parse_general_definitions(). There is no need to parse the VBT block again for SDVO device mapping. Do the same as we do in parse_ddi_ports(). We no longer have access to child device size at this stage, but we also don't need to worry about reading past the child device anymore. Instead of a child device size check, do a mild optimization by limiting the parsing to gens 3 through 7.

Ever since we've parsed VBT child devices, starting from 6acab15a ("drm/i915: use the HDMI DDI buffer translations from VBT"), we've ignored the child device information if more than one child device references the same port. The rationale for this seems lost in time. Since commit 311a2094 ("drm/i915: don't init DP or HDMI when not supported by DDI port") we started using this information more to skip HDMI/DP init if the port wasn't there per VBT child devices. However, at the same time it added port defaults without further explanation. Thus, if the child device info was skipped due to multiple child devices referencing the same port, the device info would be retrieved from the somewhat arbitrary defaults. Finally, when commit bb1d1329 ("drm/i915/vbt: split out defaults that are set when there is no VBT") stopped initializing the defaults whenever VBT is present, thus trusting the VBT more, we stopped initializing ports which were referenced by more than one child device. Apparently at least Asus UX305UA, UX305U, and UX306U laptops have VBT child device blocks which cause this behaviour. Arguably they were shipped with a broken VBT. Relax the rules for multiple references to the same port, and use the first child device info to reference a port. Retain the logic to debug log about this, though.

Apparently at least Asus UX305UA, UX305U, and UX306U laptops have VBT child device blocks which cause this behaviour. Arguably they were shipped with a broken VBT. Relax the rules for multiple references to the same port, and use the first child device info to reference a port. Retain the logic to debug log about this, though.

Cannon Lake's VBT that is currently available for B0 stepping states that port D uses alternate pin 3 messing up with the default pin-port mapping table. Using that information we cannot get HDMI working properly. So for now we don't relly on VBT for this information.

The main thing are the DDI ports. If there's a VBT that says there are no outputs, we should trust that, and not have semi-random defaults. Unfortunately, the defaults have resulted in some Chromebooks without VBT to rely on this behaviour, so we split out the defaults for the missing VBT case.

We don't use the error return for anything other than reporting and logging that there is no VBT. We can pull the logging in the function, and remove the error status return. Moreover, if we needed the information for something later on, we'd probably be better off storing the bit in dev_priv, and using it where it's needed, instead of using the error return. While at it, improve the comments.

There is at least one APL based system using port A in DP mode (connecting to an on-board DP->VGA adaptor). Atm we'll configure port A unconditionally as eDP which is incorrect in this case. Fix this by relying on the VBT DDI port 'internal port' flag instead on all ports on DDI platforms. For now chicken out from using VBT for port A before GEN9. v2: - Move the DDI port info lookup to intel_bios_is_port_edp() (David, Jani) - Use the DDI port info on all DDI platforms starting from port B.

My heuristic for detecting type 1 DVI DP++ adaptors based on the VBT port information apparently didn't survive the reality of buggy VBTs. In this particular case we have a machine with a natice HDMI port, but the VBT tells us it's a DP++ port based on its capabilities. The dvo_port information in VBT does claim that we're dealing with a HDMI port though, but we have other machines which do the same even when they actually have DP++ ports. So that piece of information alone isn't sufficient to tell the two apart. After staring at a bunch of VBTs from various machines, I have to conclude that the only other semi-reliable clue we can use is the presence of the AUX channel in the VBT. On this particular machine AUX channel is specified as zero, whereas on some of the other machines which listed the DP++ port as HDMI have a non-zero AUX channel. I've also seen VBTs which have dvo_port a DP but have a zero AUX channel. I believe those we need to treat as DP ports, so we'll limit the AUX channel check to just the cases where dvo_port is HDMI. If we encounter any more serious failures with this heuristic I think we'll have to have to throw it out entirely. But that could mean that there is a risk of type 1 DVI dongle users getting greeted by a black screen, so I'd rather not go there unless absolutely necessary. v2: Remove the duplicate PORT_A check (Daniel) Fix some typos in the commit message Cc: Daniel Otero <daniel.otero@outlook.com> Cc: stable@vger.kernel.org Tested-by: NDaniel Otero <daniel.otero@outlook.com> Fixes: d6199256 ("drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97994Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1478884464-14251-1-git-send-email-ville.syrjala@linux.intel.comReviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 7a17995a) Signed-off-by: NJani Nikula <jani.nikula@intel.com>
