Subject: [PATCH 0/5] Clean up TTM mmap offsets
Date: Thu,  7 Feb 2019 09:59:26 +0100	[thread overview]
Message-ID: <20190207085931.29569-1-tzimmermann@suse.de> (raw)

Almost all TTM-based drivers use the same values for the mmap-able
range of BO addresses. Each driver therefore duplicates the 
DRM_FILE_PAGE_OFFSET constant. OTOH, the mmap range's size is not
configurable by drivers.

This patch set replaces driver-specific configuration with a single
setup. All code is located within TTM. TTM and GEM share the same
range for mmap-able BOs.

Thomas Zimmermann (5):
  staging/vboxvideo: Use same BO mmap offset as other drivers
  drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant
  drm/ttm: Remove file_page_offset parameter from ttm_bo_device_init()
  drm/ttm: Quick-test mmap offset in ttm_bo_mmap()
  drm: Use the same mmap-range offset and size for GEM and TTM
