Our schedule is very urgent, so can anyone can help me and point out a way to solve it?
(In reply to vivianhu from comment #1) > Our schedule is very urgent, so can anyone can help me and point out a way > to solve it? Please raise any priority issues with your regular customer support channels. Otherwise, this bug is just one among many others. Please ensure you have either i915.preliminary_hw_support=1 module parameter set or CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT=y kernel config option set. Please attach dmesg from boot with drm.debug=14 module parameter set, exhibiting the problem. Please try drm-intel-nightly branch of http://cgit.freedesktop.org/drm-intel
Hi jani, thanks for your support, this problem has solved when we use drm-intel-nightly branch. Does it will be merged to kernel4.1 mainline and when?

Skylake support in v4.1 is preliminary, and we are not backporting fixes to kernels with preliminary platform support. There are features missing and/or broken, backporting fixes is not first priority.
Moreover, in this case we don't even know what the bug is, whether it's specifically in our driver or somewhere else, or how involved or invasive the backport would be. Later -rc development versions and stable kernels have pretty strict rules about what can be backported.

Hi jani, sorry to trouble you. ^-^ But we meet a new problem when we use drm-intel-nightly branch,it will report an error and many crash info in dmesg, please refer to attachment. What is i915/skl_dmc_ver4.bin and where to get it? And Does it will cause any problem if skl_dmc_ver4.bin is not loaded? what is the cut info? for example: [ 5.076518] i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver4.bin failed with error -2 [ 5.076562] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to load firmware i915/skl_dmc_ver4.bin (0) ------------[ cut here ]------------ [ 6.127802] WARNING: CPU: 0 PID: 92 at drivers/gpu/drm/i915/intel_csr.c:462 assert_csr_loaded+0xa7/0x100 [i915]() [ 6.127803] CSR is not loaded.

You can get it from https://01.org/linuxgraphics/downloads. Hopefully it will be included in linux-firmware sometime soon. There's been some back and forth between the naming, see e.g. http://mid.gmane.org/1433375419-13266-1-git-send-email-rodrigo.vivi@intel.com, I'm not sure which name is currently used in the download page.
