staging: add missing SPDX lines to Kconfig files There are a few remaining drivers/staging/*/Kconfig files that do not have SPDX identifiers in them. Add the correct GPL-2.0 identifier to them to make scanning tools happy. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

staging: vboxvideo: Add vboxvideo to drivers/staging This commit adds the vboxvideo drm/kms driver for the virtual graphics card used in Virtual Box virtual machines to drivers/staging. Why drivers/staging? This driver is already being patched into the kernel by several distros, thus it is good to get this driver upstream soon, so that work on the driver can be easily shared. At the same time we want to take our time to get this driver properly cleaned up (mainly converted to the new atomic modesetting APIs) before submitting it as a normal driver under drivers/gpu/drm, putting this driver in staging for now allows both. Note this driver has already been significantly cleaned up, when I started working on this the files under /usr/src/vboxguest/vboxvideo as installed by Virtual Box 5.1.18 Guest Additions had a total linecount of 52681 lines. The version in this commit has 4874 lines.

drm/vboxvideo: Convert vboxvideo driver to |struct drm_gem_vram_object| This patch replaces |struct vbox_bo| and its helpers with the generic implementation of |struct drm_gem_vram_object|. The only change in semantics is that &ttm_bo_driver.verify_access() now does the actual verification. v4: * select config option DRM_VRAM_HELPER v3: * remove forward declaration of struct vbox_gem_object v2: nothing Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-18-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

drm/vram: fix Kconfig select isn't recursive, so we can't turn on DRM_TTM + DRM_TTM_HELPER in config DRM_VRAM_HELPER, we have to select them on the vram users instead.

staging: vboxvideo: select GENERIC_ALLOCATOR The vboxvideo code uses various gen_pool_* functions, so it needs lib/genalloc.c to be built. In some configs this is not happening, so add select GENERIC_ALLOCATOR to the Kconfig file to enforce this. Note all other Kconfig references to GENERIC_ALLOCATOR also use select.

This is a KMS driver for the virtual Graphics Card used in
Virtual Box virtual machines.
staging: vboxvideo: Kconfig: Fix typos in help text This fixes typos in vboxvideo's help text. Most notably, "to builtin this module" becomes "to build this driver built-in to the kernel".

Although it is possible to build this driver built-in to the
kernel, it is advised to build it as a module, so that it can
be updated independently of the kernel. Select M to build this
driver as a module and add support for these devices via drm/kms
interfaces.
