Move the page allocation and freeing to driver callback and provide ttm code helper function for those. Most intrusive change, is the fact that we now only fully populate an object this simplify some of code designed around the page fault design. V2 Rebase on top of memory accounting overhaul V3 New rebase on top of more memory accouting changes V4 Rebase on top of no memory account changes (where/when is my delorean when i need it ?)

ttm_backend will only exist with a ttm_tt, and ttm_tt will only be of interest when bound to a backend. Merge them to avoid code and data duplication. V2 Rebase on top of memory accounting overhaul V3 Rebase on top of more memory accounting changes V4 Rebase on top of no memory account changes (where/when is my delorean when i need it ?) V5 make sure ttm is unbound before destroying, change commit message on suggestion from Tormod Volden Signed-off-by:

Split btw highmem and lowmem page was rendered useless by the pool code. Remove it. Note further cleanup would change the ttm page allocation helper to actualy take an array instead of relying on list this could drasticly reduce the number of function call in the common case of allocation whole buffer.

This was never use in none of the driver, properly using userspace page for bo would need more code (vma interaction mostly). Removing this dead code in preparation of ttm_tt & backend merge. Signed-off-by:

As a mechanism to detect whether SWIOTLB is enabled or not. We also fix the spelling - it was swioltb instead of swiotlb. CC: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> [v1: Ripped out swiotlb_enabled] Signed-off-by: -

Merge topic branch with some of Jesse's cleanups, the save/restore hooks were being used by GMA500 so we can't just drop them. * drm-cleanups-jbarnes: drm: remove some potentially dangerous DRM_ERRORs drm: document the drm_mode_config structure drm: document the drm_mode_group structure drm: document and cleanup drm_mode_config_funcs drm: document drm_mode_set structure drm: remove unused fields in drm_connector and document the rest drm: add drm_encoder comments drm: add comments for drm_encoder_funcs drm: fix comments for drm_crtc struct drm: remove unused connector_count field from drm_display_mode

Each of these error messages can be caused by a broken or malicious userspace wanting to spam the dmesg with useless info. They're really not worthy of DRM_DEBUG statements either; those are generally only useful during bringup of new hardware or versions, and ought to be removed before going upstream anyway.

We never used initial_x/y or the force_encoder_id, so drop those fields and proide a basic description of the others. Really, the ELD bits belong in drm_display_info rather than directly in the connector, but that's a separate cleanup. Signed-off-by:

The Oaktrail platform does not use the GCT/VBT format that is used by the Moorestowm (non PC legacy) equivalent device. It uses the BIOS tables which means an opregion and the like. The current code uses the wrong table which breaks things like the Fujitsu q550 tablets. Fix the table usage as a first step. The problem was found and diagnosed by Chia-I Wu Signed-off-by:

Add support for GTT based scrolling. Instead of pushing bits around we simply use the GTT to change the mappings. This provides us with a very fast way to scroll the display providing we have enough memory to allocate on 4K line boundaries. In practice this seems to be the case except for very big displays such as HDMI, and the usual configurations are netbooks/tablets. Signed-off-by:

If we are the console then a printk can hit us with a spin lock held (and in fact the kernel will do its best to take the console printing lock). In that case we cannot politely sleep when synching after an accelerated op but must behave obnoxiously to be sure of getting the bits out. Signed-off-by:

This isn't actually usable - we simply don't have the vmap space on a 32bit system to do this stunt. Instead we will rely on the low level drivers limiting the console resolution as before. The real fix is for someone to write a page table aware version of the framebuffer console blit functions. Good university student project perhaps.. Signed-off-by:

Name the formats as DRM_FORMAT_X instead of DRM_FOURCC_X. Use consistent names, especially for the RGB formats. Component order and byte order are now strictly specified for each format. The RGB format naming follows a convention where the components names and sizes are listed from left to right, matching the order within a single pixel from most significant bit to least significant bit. The YUV format names vary more. For the 4:2:2 packed formats and 2 plane formats use the fourcc. For the three plane formats the name includes the plane order and subsampling information using the standard subsampling notation. Some of those also happen to match the official fourcc definition. The fourccs for for all the RGB formats and some of the YUV formats I invented myself. The idea was that looking at just the fourcc you get some idea what the format is about without having to decode it using some external reference. Signed-off-by:
