2017-06-13drm/i915: Fix GVT-g PVINFO version compatibility checkZhenyu Wang-6/+2
Current it's strictly checked if PVINFO version matches 1.0 for GVT-g i915 guest which doesn't help for compatibility at all and forces GVT-g host can't extend PVINFO easily with version bump for real compatibility check. This fixes that to check minimal required PVINFO version instead. v2: - drop unneeded version macro - use only major version for sanity check v3: - fix up PVInfo value with kernel type - one indent fix Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chuanxiao Dong <chuanxiao.dong@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: stable@vger.kernel.org # v4.10+ Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170609074805.5101-1-zhenyuw@linux.intel.com (cherry picked from commit 0c8792d00d38de85b6ceb1dd67d3ee009d7c8e42) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-06-17drm/i915: Use offsetof() to calculate the offset of members in PVINFO pageZhi Wang-1/+1
To get the offset of the members in PVINFO page, offsetof() looks much better than the tricky approach in current code. v7: - Move "offsetof()" modification into a dedicated patch.

2016-06-17drm/i915: Factor out i915_pvinfo.hZhi Wang-0/+113
As the PVINFO page definition is used by both GVT-g guest (vGPU) and GVT-g host (GVT-g kernel device model), factor it out for better code structure. v7: - Split the "offsetof" modification into a dedicated patch.
