Hi folks:
Here is the pull of gvt-next which fixs the compilation error when i915 debug
is open after the GVT-g refactor patches.
Thanks so much for the efforts.
Thanks,
Zhi.

This still has another compile problem:
ERROR: modpost: "intel_runtime_pm_put" [vmlinux] is a static EXPORT_SYMBOL_GPL
Because:
#if IS_ENABLED(CONFIG_DRM_I915_DEBUG_RUNTIME_PM)
void intel_runtime_pm_put(struct intel_runtime_pm *rpm, intel_wakeref_t wref);
#else
static inline void
intel_runtime_pm_put(struct intel_runtime_pm *rpm, intel_wakeref_t wref)
{
intel_runtime_pm_put_unchecked(rpm);
}
#endif
Looks like it happens if CONFIG_DRM_I915_DEBUG_RUNTIME_PM=n
I think you probably want to #ifdef the export in the same way:
--- a/drivers/gpu/drm/i915/intel_gvt.c
+++ b/drivers/gpu/drm/i915/intel_gvt.c
@@ -309,7 +309,9 @@ EXPORT_SYMBOL_NS_GPL(__intel_context_do_pin, I915_GVT);

Sigh. That's tricky. Let me prepare another one.
Also the following compile error:
drivers/gpu/drm/i915/gvt/handlers.c:75:6: error: no previous prototype
for ‘intel_gvt_match_device’ [-Werror=missing-prototypes]
75 | bool intel_gvt_match_device(struct intel_gvt *gvt,
| ^~~~~~~~~~~~~~~~~~~~~~
it was removed from a header. The implementation should now be made static
EXPORT_SYMBOL_NS_GPL(intel_runtime_pm_put_unchecked, I915_GVT);
EXPORT_SYMBOL_NS_GPL(intel_uncore_forcewake_for_reg, I915_GVT);
EXPORT_SYMBOL_NS_GPL(intel_uncore_forcewake_get, I915_GVT);
