similar to: [Bug 49746] New: EDID checksum is invalid

Hello, I've tried several times yesterday to build R-devel and I consistently get this error when I "make" : mkdir -p -- ../../../library/base/R make[3]: Leaving directory `/tmp/R-devel/src/library/profile' make[3]: Entering directory `/tmp/R-devel/src/library/base' building package 'base' make[4]: Entering directory `/tmp/R-devel/src/library/base' mkdir -p --

It looks like Ryan's Nouveau patch [1,2] to get the I2C working for EDID (thus modelines) is crucial for avoiding the Nvidia binary drivers on MacbookPro 2012s. Any plans/chance for it to be upstreamed to eg 3.6-rc3?

Ben, I think I'm being hit with this bug (I see EDID is invalid in dmesg), is there any workaround outside of recompiling without that commit and can I give any information to help?

I don't have the cycles to maintain edid-decode, and Hans Verkuil (who contributed a ton of HDMI-related patches) has graciously offered to take over.

Check first two header bytes before trying to read the edid blob, to avoid the log being spammed in case qemu has no edid support (old qemu or edid turned off).

Check header before trying to read the complete edid blob, to avoid the log being spammed in case qemu has no edid support (old qemu or edid support turned off).

I cant make the nouveau work with an arcade monitor, problably because the EDID. I can make modeline work fine to reduce the horizontal to 15khz, tested in a normal pc monitor (with ugly visual because the 15khz in horizontal). But when i try in the arcade monitor, dont show any image after xorg start. In official nvidia driver has an option NOEDID to force the driver to ignore information from

Hi, Bisected this to: commit df8dc97cd17269474344d73cc02739532c468d04 Author: Ben Skeggs <bskeggs at redhat.com> Date: Wed Mar 1 09:42:04 2017 +1000 drm/nouveau/kms/nv50: use drm core i2c-over-aux algorithm I'm not entirely sure NVKM needs to support this now, but I haven't removed it as of yet just in case it's needed from DEVINIT scripts where DRM isn't

Thanks, Lukas. I've incorporated your feedback into my local tree, but will wait for additional feedback from the individual DRM driver maintainers before sending out a series v2.
