[PATCH 1/2] drm/mediatek: set panel orientation before drm_dev_register().
by Hsin-Yi Wang 26 Apr '21

26 Apr '21

drm_dev_register() sets connector->registration_state to DRM_CONNECTOR_REGISTERED and dev->registered to true. If drm_connector_set_panel_orientation() is first called after drm_dev_register(), it will fail several checks and results in following warning. So set panel orientation in dsi before drm_dev_register() is called.

[PATCH v5] dma-buf: Add DmaBufTotal counter in meminfo

This adds a total used dma-buf memory. Details can be found in debugfs, however it is not for everyone and not always available. dma-buf are indirect allocated by userspace.

[PATCH] vfio/gvt: fix DRM_I915_GVT dependency on VFIO_MDEV
by Arnd Bergmann 25 Apr '21

25 Apr '21

From: Arnd Bergmann <arnd(a)arndb.de> The Kconfig dependency is incomplete since DRM_I915_GVT is a 'bool' symbol that depends on the 'tristate' VFIO_MDEV. This allows a configuration with VFIO_MDEV=m, DRM_I915_GVT=y and DRM_I915=y that causes a link failure: x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `available_instances_show': gvt.c:(.text+0x67a): undefined reference to `mtype_get_parent_dev' x86_64-linux-ld: gvt.c:(.text+0x6a5): undefined reference to `mtype_get_type_group_id' x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `description_show': gvt.c:(.text+0x76e): undefined reference to `mtype_get_parent_dev' x86_64-linux-ld: gvt.c:(.text+0x799): undefined reference to `mtype_get_type_group_id' Clarify the dependency by specifically disallowing the broken configuration. If VFIO_MDEV is built-in, it will work, but if VFIO_MDEV=m, the i915 driver cannot be built-in here.
