PCI- or high memory.
This is substantially more efficient than drm_bo_kmap,
since the mapping only lives on a single processor.
Unmapping is done use kunmap_atomic(). Flushes only a single tlb() entry.
Add a support utility int drm_bo_pfn_prot() that returns the
pfn and desired page protection for a given bo offset.
This is all intended for relocations in bound TTMS or vram.
Mapping-accessing-unmapping must be atomic, either using preempt_xx() macros
or a spinlock.

Flags pending validation were stored in a misleadingly named field, 'mask'.
As 'mask' is already used to indicate pieces of a flags field which are
changing, it seems better to use a name reflecting the actual purpose of
this field. I chose 'proposed_flags' as they may not actually end up in
'flags', and in an case will be modified when they are moved over.
This affects the API, but not ABI of the user-mode interface.

Aside from changing drm_bind_ttm to drm_ttm_bind, this patch
adds only documentation and fixes the functions inside drm_ttm.c
to all be prefixed with drm_ttm_.
|
|
Creating a ttm was done with drm_ttm_init while destruction was done with
drm_destroy_ttm. Renaming these to drm_ttm_create and drm_ttm_destroy makes
their use clearer. Passing page_flags to the create function will allow that
to know whether user or kernel pages are needed, with the goal of allowing
kernel ttms to be saved for later reuse.

Kernel "cleanfile" script run.

Also no need to do pre-populate work on single page

Mostly removing typedefs that snuck into the modesetting code and
updating to the latest TTM APIs. As of today, the i915 driver builds,
but there are likely to be problems, so debugging and bugfixes will
come next.

Modify the TTM backend bind arguments.
Export a number of functions needed for driver-specific super-ioctls.
Add a function to map buffer objects from the kernel, regardless of where they're
currently placed.
A number of error fixes.

Buffer object dereference cleanup.
Add a struct drm_device member to fence objects:
This can simplify code, particularly in drivers.
|
|
We need to keep a list of user created fbs to nuke on master exit.
We also need to use the bo properly.
|
|
allocation correctly, and use drm_mem_reg_iomap to map ring buffer object.
|
|
(Fence objects belonging to different command submission mechanisms).
|
|
Fixed memory, pinned buffers and unmappable memory now seems
fully functional.
|
|
|
|
|
|
|
|
|
|
Fixed - to System memory copies are implemented by
flipping in a cache-coherent TTM,
blitting to it, and then flipping it out.
|
|
|
|
Implement unmappable buffers. (fault moves them to mappable when needed).
Various bugfixes.
|
|
Export helper functions and make some important buffer-object functions non-static.
Add an i915 accelerated blit buffer move for pci memory buffers.
|
|
|
|
Some other minor fixes.
|
|
Hooray!! it sort of works with a fixed AGP area as faked VRAM.
|
|
Implement a memcpy fallback for copying between buffers.
|
|
Flag handling and memory type selection cleanup.
glxgears won't start.
|
|
Add a file for memory move helpers, drm_bo_move.c
Implement generic memory move.
Cached, no_move and unmapped memory temporarily broken.
