drm/i915/guc: Introduce USES_GUC_xxx helper macros

2017-12-06T14:41:49Z

In the upcoming patch we will change the way how to recognize when GuC is in use. Using helper macros will minimize scope of that changes. While here, update dev_info message.

drm/i915: Remove i915.enable_execlists module parameter

2017-11-20T21:53:59Z

Execlists and legacy ringbuffer submission are no longer feature comparable (execlists now offer greater functionality that should overcome their performance hit) and obsoletes the unsafe module parameter, i.e. comparing the two modes of execution is no longer useful, so remove the debug tool.

drm/i915: Rename global i915 to i915_modparams

2017-09-22T11:50:36Z

Our global struct with params is named exactly the same way as new preferred name for the drm_i915_private function parameter. To avoid such name reuse lets use different name for the global. v5: pure rename v6: fix Credits-to: Coccinelle @@ identifier n; @@ ( - i915.n + i915_modparams.n ) Signed-off-by: Michal Wajdeczko Cc: Jani Nikula Cc: Chris Wilson Cc: Tvrtko Ursulin Cc: Ville Syrjala Cc: Joonas Lahtinen Acked-by: Joonas Lahtinen Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20170919193846.38060-1-michal.wajdeczko@intel.com

drm/i915/gvt: Extend KBL platform support in GVT-g

Extend KBL platform support in GVT-g. Validation tests are done on KBL server and KBL NUC. Both show the same quality. Signed-off-by: Jian Jun Chen Cc: Zhenyu Wang Signed-off-by: Zhenyu Wang

drm/i915/gvt: Return -EIO if host GuC submission is enabled when loading GVT-g

2017-05-30T13:00:07Z

Currently GVT-g cannot work properly when host GuC submission is enabled, so make the driver loading failed in this case. v2: - use DRM_ERROR as it is a fatal message.

drm/i915/gvt: Return -EIO if host enable_execlists not enabled when loading GVT-g

2017-05-30T12:59:56Z

GVT-g relies on the enable_execlists parameter in i915. If this option is not enabled for GVT-g, should return -EIO to make i915 driver loading failed. v2: - Use DMR_ERROR as it is a fatal message.

drm/i915: make intel_gvt_init() later instead of too early

2017-02-07T09:21:06Z

Previously intel_gvt_init() was called very early even before MMIO initialization which had several drawbacks: - Have to handle MMIO access for initial MMIO state dump if golden state firmware is not available - Hypervisor detection should depend on pvinfo only instead of detecting hypervisor status. - Don't know hw resource size e.g aperture, ggtt size to determine for vGPU type, etc. This trys to move intel_gvt_init() call late after required info has already been initialized for GVT host.
