Have you fixed the lkp issue? I didn't see you pushed the code to github.

Tomas, Lkp issue is complaining about the header drm/i915_mei_hdcp_interface.h, Which is already merged in drm-tip through below commit. So don’t think this is a genuine issue. May be this build was tried in different tree, where this commit is not added yet? commit 1626eab70ebc61d015e69a4bc3479d9228539343 Author: Ramalingam C <ramalingam.c@intel.com> Date: Fri Feb 15 14:04:58 2019 +0530 drm/i915: header for i915 - MEI_HDCP interface v15 is now part of github.

Yeah our topic trees aren't pushed into linux-next, 0day can't find them. Usually it will then fail to apply (and in that case it doesn't complain), but it does complain if everything applies but doesn't build. -Daniel > > commit 1626eab70ebc61d015e69a4bc3479d9228539343 > Author: Ramalingam C <ramalingam.c@intel.com> > Date: Fri Feb 15 14:04:58 2019 +0530 > > drm/i915: header for i915 - MEI_HDCP interface > > v15 is now part of github. > > Best Regards, > Ramalingam C > > > > -----Original Message----- > > From: Winkler, Tomas > > Sent: Monday, February 25, 2019 1:45 AM > > To: C, Ramalingam <ramalingam.c@intel.com>; intel-gfx@lists.freedesktop.org; > > dri-devel@lists.freedesktop.org; daniel.vetter@ffwll.ch; Shankar, Uma > > <uma.shankar@intel.com> > > Subject: RE: [PATCH v15 00/16] drm/i915: Implement HDCP2.2 > > > > Have you fixed the lkp issue? > > I didn't see you pushed the code to github. > > Thanks > > > > > > > -----Original Message----- > > > From: C, Ramalingam > > > Sent: Sunday, February 24, 2019 18:33 > > > To: intel-gfx@lists.freedesktop.org; dri-devel@lists.freedesktop.org; > > > daniel.vetter@ffwll.ch; Winkler, Tomas <tomas.winkler@intel.com>; > > > Shankar, Uma <uma.shankar@intel.com> > > > Subject: Re: [PATCH v15 00/16] drm/i915: Implement HDCP2.2 > > > > > > Tomas, > > > > > > Could you please help to review and give final "Go" for the series? > > > > > > Thanks > > > --Ram. > > > > > > On 2/21/2019 11:41 PM, Ramalingam C wrote: > > > > This series enables the HDCP2.2 Type 0 for I915.

Ok, merged all the 15 patches into a topic branch. Assuming nothing goes wrong I'll send a pull to Greg tomorrow. And then it's up to him to take it for 5.1 or delay for 5.2.
