Some machines have IFWIs that do not support PXP, so we need it to be an opt-in until we add support to query the caps from the mei device. v10: change comments from "Gen12+" to "Gen12 and newer" Signed-off-by: Alan Previn Signed-off-by: Daniele Ceraolo Spurio Reviewed-by: Rodrigo Vivi Signed-off-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-4-alan.previn.teres.alexis@intel.com --- diff --git a/drivers/gpu/drm/i915/Kconfig b/drivers/gpu/drm/i915/Kconfig index f960f5d7664e6..8859444943a08 100644 --- a/drivers/gpu/drm/i915/Kconfig +++ b/drivers/gpu/drm/i915/Kconfig @@ -131,6 +131,17 @@ config DRM_I915_GVT_KVMGT Choose this option if you want to enable KVMGT support for Intel GVT-g. +config DRM_I915_PXP + bool "Enable Intel PXP support for Intel Gen12 and newer platform" + depends on DRM_I915 + depends on INTEL_MEI && INTEL_MEI_PXP + default n + help + PXP (Protected Xe Path) is an i915 component, available on GEN12 and + newer GPUs, that helps to establish the hardware protected session and + manage the status of the alive software session, as well as its life + cycle. + menu "drm/i915 Debugging" depends on DRM_I915 depends on EXPERT diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 93d13aba6a850..357faa043b3af 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -1700,6 +1700,9 @@ IS_SUBPLATFORM(const struct drm_i915_private *i915, #define HAS_GLOBAL_MOCS_REGISTERS(dev_priv) (INTEL_INFO(dev_priv)->has_global_mocs) +#define HAS_PXP(dev_priv) ((IS_ENABLED(CONFIG_DRM_I915_PXP) && \ + INTEL_INFO(dev_priv)->has_pxp) && \ + VDBOX_MASK(&dev_priv->gt)) #define HAS_GMCH(dev_priv) (INTEL_INFO(dev_priv)->display.has_gmch) diff --git a/drivers/gpu/drm/i915/intel_device_info.h b/drivers/gpu/drm/i915/intel_device_info.h index d328bb95c49bf..8e6f48d1eb7bc 100644 --- a/drivers/gpu/drm/i915/intel_device_info.h +++ b/drivers/gpu/drm/i915/intel_device_info.h @@ -133,6 +133,7 @@ enum intel_ppgtt_type { func(has_logical_ring_elsq); \ func(has_mslices); \ func(has_pooled_eu); \ + func(has_pxp); \ func(has_rc6); \ func(has_rc6p); \ func(has_rps); \
