2008-02-28Add a compat kmap_atomic_prot_pfn to do quick kernel map / unmaps ofThomas Hellstrom
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.
2007-12-21Rename inappropriately named 'mask' fields to 'proposed_flags' instead.Keith Packard
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.
2007-12-21Clean up and document drm_ttm.c APIs. drm_bind_ttm -> drm_ttm_bind.Keith Packard
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_.
2007-12-15Make ttm create/destroy APIs consistent. Pass page_flags in create.Keith Packard
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.

2007-10-26Buffer flags and masks are 64-bit.Thomas Hellstrom
don't mask off the high dword. Signed-off-by: Thomas Hellstrom <thomas-at-tungstengraphics-dot-com>
2007-10-04drm: fix page count calculationDave Airlie
Also no need to do pre-populate work on single page
2007-09-22Add fence error member.Thomas Hellstrom
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.
2007-08-06Export some useful ttm functions to drivers.Ben Skeggs
2007-07-16drm: detypedef ttm/bo/fence codeDave Airlie
2007-07-16drm: remove drmP.h internal typedefsDave Airlie
2007-06-29Fence object reference / dereference cleanup.Thomas Hellstrom
Buffer object dereference cleanup. Add a struct drm_device member to fence objects: This can simplify code, particularly in drivers.
2007-02-15Initial support for fence object classes.Thomas Hellstrom
(Fence objects belonging to different command submission mechanisms).
2007-02-13More bugfixes.Thomas Hellstrom
Fixed memory, pinned buffers and unmappable memory now seems fully functional.
2007-02-12Lindent.Thomas Hellstrom
2007-02-12More bugfixes.Thomas Hellstrom
2007-02-12Cleanup and fix support for pinned buffers.Thomas Hellstrom
2007-02-10Various bugfixes.Thomas Hellstrom
2007-02-09I915 accelerated blit copy functional.Thomas Hellstrom
Fixed - to System memory copies are implemented by flipping in a cache-coherent TTM, blitting to it, and then flipping it out.
2007-02-09Fix copyright statements.Thomas Hellstrom
2007-02-09Fix evict_mutex locking range.Thomas Hellstrom
Implement unmappable buffers. (fault moves them to mappable when needed). Various bugfixes.
2007-02-08Add an accelerated buffer copy cleanup helper.Thomas Hellstrom
Export helper functions and make some important buffer-object functions non-static. Add an i915 accelerated blit buffer move for pci memory buffers.
2007-02-08Don't create a ttm just to copy from.Thomas Hellstrom
2007-02-08Fix mm_block leak.Thomas Hellstrom
Some other minor fixes.
2007-02-08A minor function interface change and some memcpy bugfixing.Thomas Hellstrom
Hooray!! it sort of works with a fixed AGP area as faked VRAM.
2007-02-08Simplify external ttm page allocation.Thomas Hellstrom
Implement a memcpy fallback for copying between buffers.
2007-02-07Checkpoint commit.Thomas Hellstrom
Flag handling and memory type selection cleanup. glxgears won't start.
2007-02-07Fix a stray unlock_kernel() in drm_vm.cThomas Hellstrom
Add a file for memory move helpers, drm_bo_move.c Implement generic memory move. Cached, no_move and unmapped memory temporarily broken.
