Restore the 1.23 version to the linux firmware repo imo. It's a regression, best way to fix it is by (partial) revert. -Daniel > > -----Original Message----- > From: Nikula, Jani > Sent: Monday, August 01, 2016 6:25 AM > To: Vivi, Rodrigo; Herbert, Marc; Deak, Imre; chris@xxxxxxxxxxxxxxxxxx > Cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx > Subject: Re: [PATCH] drm/i915/dmc: Accept symbolic link in firmware name > > On Wed, 20 Jul 2016, "Vivi, Rodrigo" <rodrigo.vivi@xxxxxxxxx> wrote: > > We don't hardcode all userspace libraries in the userspace side for > > the graphics stack and we do not validate all possible combinations of > > libdrm, mesa, ddx, libva, etc...

The kernel provides an ABI with a strict no regressions policy for its users. The firmware has no such guarantees, and it is expected to go hand in hand with the operating system versions it has been validated against. And as I've explained numerous times, we do not have the resources to validate all kernel releases against all firmware releases. > > > BR, > Jani. > > > -- > Jani Nikula, Intel Open Source Technology Center > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
