Subject: drm/vmwgfx: Allow checking for gl43 contexts
Git-commit: abaad3d95b5117a17886d37cf0228712801cd259
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
To make sure we're running on top of hardware that can support
GL4.3 we need to add a way of querying for those capabilities.
DRM_VMW_PARAM_GL43 allows userspace to check for presence of
GL4.3 capable contexts.
