2017-01-27drm/amdgpu: Refine the way to get atom biosKen Xue
There are several ways to check out a ATOMBIOS. In previous codes, try a new way to fetch out vbios/rom, until current vbios/rom is started with 0x55aa, then check if this vbios is ATOMBIOS. Now, try a new way to fetch out vbios until all flags of ATOMBIOS are verified.

2017-01-27drm/amd/amdgpu: get maximum and used UVD handles (v4)Arindam Nath
Change History -------------- v4: Changes suggested by Emil, Christian - return -ENODATA for asics with unlimited sessions v3: changes suggested by Christian - Add a check for UVD IP block using AMDGPU_HW_IP_UVD query type. - Add a check for asic_type to be less than CHIP_POLARIS10 since starting Polaris, we support unlimited UVD instances. - Add kerneldoc style comment for amdgpu_uvd_used_handles(). v2: as suggested by Christian - Add a new query AMDGPU_INFO_NUM_HANDLES - Create a helper function to return the number of currently used UVD handles. - Modify the logic to count the number of used UVD handles since handles can be freed in non-linear fashion. v1: - User might want to query the maximum number of UVD instances supported by firmware. In addition to that, if there are multiple applications using UVD handles at the same time, he might also want to query the currently used number of handles. For this we add two variables max_handles and used_handles inside drm_amdgpu_info_hw_ip. So now an application (or libdrm) can use AMDGPU_INFO IOCTL with AMDGPU_INFO_HW_IP_INFO query type to get these values.

The wrong pixel format will be rejected by vmw_kms_new_framebuffer(), thus leaving par->set_fb to NULL.

git://people.freedesktop.org/~airlied/linux Pull drm revert from Dave Airlie: "Revert one patch missing some prereqs. One of the connector fixes was missing some prereqs, we have an alternate driver fix that should work that I'll send tomorrow. Today is a holiday here so quickly smashing this out" Daniel Vetter explains: "I pushed a locking change to fix a nouveau rpm issue to -fixes that needed the connector_list rework. And that's only in -next, but I missed that. Dave has the revert in a pull, and he'll follow-up with the hack nouveau patch for 4.10, and then we'll reapply the proper fix again for -next and revert the hacks. A bit a mess, but should be sorted soon" * tag 'drm-fixes-for-v4.10-rc6-revert-one' of git://people.freedesktop.org/~airlied/linux: Revert "drm/probe-helpers: Drop locking from poll_enable"
2017-01-26drm/edid: Set YQ bits in the AVI infoframe according to CEA-861-FVille Syrjälä
CEA-861-F tells us: "When transmitting any RGB colorimetry, the Source should set the YQ-field to match the RGB Quantization Range being transmitted (e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB, set YQ=1) and the Sink shall ignore the YQ-field." So let's go ahead and do that. Perhaps there are sinks that don't ignore the YQ as they should for RGB? I wasn't able to find similar text in CEA-861-E, so it would seem to be a fairly "recent" addition.

2017-01-26drm/edid: Set AVI infoframe Q even when QS=0Ville Syrjälä
HDMI 2.0 recommends that we set the Q bits in the AVI infoframe even when the sink does not support quantization range selection (QS=0). According to CEA-861 we can do that as long as the Q we send matches the default quantization range for the mode. Previously I think I had misread the spec as saying that you can't send a non-zero Q at all when QS=0. But that's not what the spec actually says. v2: Fix typo in commit message (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170111125725.8086-5-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com> Acked-by: Eric Anholt <eric@anholt.net>
2017-01-26drm/edid: Introduce drm_hdmi_avi_infoframe_quant_range()Ville Syrjälä
Pull the logic to populate the quantization range information in the AVI infoframe into a small helper. We'll be adding a bit more logic to it, and having it in a central place seems like a good idea since it's based on the CEA-861 spec.
