2020-03-12drm/vmwgfx: Drop preempt_disable() in vmw_fifo_ping_host()Sebastian Andrzej Siewior
vmw_fifo_ping_host() disables preemption around a test and a register write via vmw_write(). The write function acquires a spinlock_t typed lock which is not allowed in a preempt_disable()ed section on PREEMPT_RT. This has been reported in the bugzilla. It has been explained by Thomas Hellstrom that this preempt_disable()ed section is not required for correctness. Remove the preempt_disable() section.

2020-03-12drm/vmwgfx: Refuse DMA operation when SEV encryption is activeThomas Hellstrom
TTM doesn't yet fully support mapping of DMA memory when SEV is active, so in that case, refuse DMA operation. For guest-backed object operation this means 3D acceleration will be disabled. For host-backed, VRAM will be used for data transfer between the guest and the device. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Brian Paul <brianp@vmware.com>
2020-03-12drm/vmwgfx: Fix the refuse_dma mode when using guest-backed objectsThomas Hellstrom
When we refuse DMA from system pages for whatever reason, we don't handle that correctly when guest-backed objects was enabled. Since guest-backed objects by definition require DMA to and from system pages, disable all functionality that relies on them. That basically amounts to 3D acceleration and screen targets.

2020-03-11drm/rockchip: rgb: don't count non-existent devices when determining subdriversHeiko Stuebner
rockchip_drm_endpoint_is_subdriver() may also return error codes. For example if the target-node is in the disabled state, so no platform-device is getting created for it. In that case current code would count that as external rgb device, which in turn would make probing the rockchip-drm device fail. So only count the target as rgb device if the function actually returns 0.

2020-03-10drm/i915/mst: Hookup DRM DP MST late_register/early_unregister callbacksLyude Paul
i915 can enable aux device nodes for DP MST by calling drm_dp_mst_connector_late_register()/ drm_dp_mst_connector_early_unregister(), so let's hook that up. Changes since v1: * Call intel_connector_register/unregister() from intel_dp_mst_connector_late_register/unregister() so we don't lose error injection - Ville Syrjälä Changes since v2: * Don't forget to clean up if intel_connector_register() fails - Ville Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: "Lee, Shawn C" <shawn.c.lee@intel.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200310195122.1590925-1-lyude@redhat.com
