Use the GMBUS interface rather than direct bit banging to grab the EDID over DDC (and for other forms of auxiliary communication with external display controllers). The hope is that this method will be much faster and more reliable than bit banging for fetching EDIDs from buggy monitors or through switches, though we still preserve the bit banging as a fallback in case GMBUS fails.

Destructive load-detection is very expensive and due to failings elsewhere can trigger system wide stalls of up to 600ms. A simple first step to correcting this is not to invoke such an expensive and destructive load-detection operation automatically.

Commit 77d07fd9 introduced a regression where by not waiting for the panel to be turned off, left the panel and PLL registers locked across the modeset. Thus the panel remaining blank. As pointed out by Daniel Vetter, when testing LVDS it helps to open the laptop and look at the actual panel you are purporting to test. A second issue with the patch was that in order to modify the panel fitter before gen5, the pipe and the panel must have be completely powered down. So we wait.

Jesse's feedback from using the wait_for() macro was that the msleep argument was that it was superfluous and made the macro more difficult to use and to read. As the actually amount of time to sleep is not critical, the crucial part is to sleep and let the processor schedule something else whilst we wait for the event, replace the argument with a hardcoded value.

This one replaces original param for intel_ddc_get_modes() with DRM connector and i2c bus adapter instead. With explicit params, we won't require that a single driver structure must hold connector and DDC bus reference, which ease the conversion to splitted encoder/ connector model. It also clears up for some cases that we would steal other DDC bus for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed a bug in old DVI-I probe handling, that failed to restore origin analog GPIO port. Signed-off-by: NZhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: NEric Anholt <eric@anholt.net>

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors. This patch is produced by sed s/intel_output/intel_encoder/ over the driver. Signed-off-by: NEric Anholt <eric@anholt.net>

I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so.

It would be good to disable the LVDS port when we shut down the panel to save power. We haven't done so until now because we had trouble getting the right LVDS parameters from the BIOS. I think we're past that now, so enabling and disabling the port should be safe, though it would probably be made cleaner with some additional changes to the display code, where we also bang on the LVDS reg to set the pairing correctly etc. Seems to save a bit of power (up to 300mW in my basic wattsup meter testing).
