iwlwifi: mvm: support unification of INIT and RT images
For a000 devices the INIT and RT images are unified to one image. The changes in the flow are the following: * Driver load only RT firmware - meaning that the nvm access command will be done in the RT image load flow. * A new command (NVM_ACCESS_COMPLETE) now signals to the FW that the driver is done accessing the NVM and FW can proceed with phy calibrations. * Phy DB is no longer sent from INIT FW to be restored by driver for the RT FW - all the phy DB is now internal to the FW. INIT complete will now follow the NVM access command, without phy DB calls before. * Paging command is sent earlier in the flow before NVM access to enable a complete load of FW. * caution must be care when restart is called since we may have not completed init flow even though we are in RT firmware.

+0x48/0x4d0 kthread+0x101/0x140 and this patch purely papers over the issue by adding a NULL pointer check and a WARN_ON_ONCE() to avoid the oops that would then generally make the machine unresponsive. Other callers of i915_gem_object_to_ggtt() seem to also check for the returned pointer being NULL and warn about it, so this clearly has happened before in other places. [ Reported it originally to the i915 developers on Jan 8, applying the ugly workaround on my own now after triggering the problem for the second time with no feedback. This is likely to be the same bug reported as https://bugs.freedesktop.org/show_bug.cgi?id=98829 https://bugs.freedesktop.org/show_bug.cgi?id=99134 which has a patch for the underlying problem, but it hasn't gotten to me, so I'm applying the workaround. ] Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
