2008-01-30Simplify the fencing code and differentiate between flushes andThomas Hellstrom
waiting types. Add a "command_stream_barrier" method to the bo driver.
2007-12-21Change drm_bo_type_dc to drm_bo_type_device and comment usage of this value.Keith Packard
I couldn't figure out what drm_bo_type_dc was for; Dave Airlie finally clued me in that it was the 'normal' buffer objects with kernel allocated pages that could be mmapped from the drm device file. I thought that 'drm_bo_type_device' was a more descriptive name. I also added a bunch of comments describing the use of the type enum values and the functions that use them.
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.
2007-12-21Move dummy_read_page from drm_ttm_set_user to drm_ttm_create.Keith Packard
I'm hoping to use the dummy_read_page for kernel allocated buffers to avoid allocating extra pages for read-only buffers (like vertex and batch buffers). This also eliminates the 'write' parameter to drm_ttm_set_user and just has DRM_TTM_PAGE_WRITE passed into drm_ttm_create.
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_.
2007-12-15Document drm_buffer_object_validate function.Keith Packard
Just add documentation for this function, no code changes.
2007-12-15Document fence_class mess in drm_bo_setstatus_ioctlKeith Packard
drmBOSetStatus does not bother to set the fence_class parameter. Fortunately, drm_bo_setstatus_ioctl doesn't end up using it as it calls drm_bo_handle_validate with use_old_fence_class = 1.
2007-12-15Document drm_bo_handle_validate. Match drm_bo_do_validate parameter order.Keith Packard
Document parameters and usage for drm_bo_handle_validate. Change parameter order to match drm_bo_do_validate (fence_class has been moved to after flags, hint and mask values). Existing users of this function have been changed, but out-of-tree users must be modified separately.
2007-12-15Document drm_bo_do_validate. Remove spurious 'do_wait' parameter.Keith Packard
Add comments about the parameters to drm_bo_do_validate, along with comments for the DRM_BO_HINT options. Remove the 'do_wait' parameter as it is duplicated by DRM_BO_HINT_DONT_BLOCK.
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.

2007-11-01drm/ttm: add support for cached un-snooped mappings.Dave Airlie
This mapping allows cached objects to be mapped in/out of the TT space with the appropriate flushing calls. It should put back the old CACHED functionality for snooped mappings
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>
2007-10-25Buffer manager:Thomas Hellstrom
Implement a version check IOCTL for drivers that don't use drmMMInit from user-space. Remove the minor check from the kernel code. That's really up to the driver. Bump major.

2007-10-19Remove the clean_unfenced function.Thomas Hellstrom
Change the restriction that non-creators can't change the buffer flags to non-creators can't change EVICT and NO_MOVE flags.
2007-10-17Only allow creator to change shared buffer mask.Thomas Hellstrom
2007-10-17Remove the op ioctl, and replace it with a setuser ioctl.Thomas Hellstrom
Remove need for lock for now. May create races when we clean memory areas or on takedown. Needs to be fixed. Really do a validate on buffer creation in order to avoid problems with fixed memory buffers.

2007-10-16Drop destroy ioctls for fences and buffer objects.Kristian Høgsberg
We now always create a drm_ref_object for user objects and this is then the only things that holds a reference to the user object. This way unreference on will destroy the user object when the last drm_ref_object goes way.
2007-10-16Take bo type argument out of the ioctl interface.Kristian Høgsberg
The buffer object type is still tracked internally, but it is no longer part of the user space visible ioctl interface. If the bo create ioctl specifies a non-NULL buffer address we assume drm_bo_type_user, otherwise drm_bo_type_dc. Kernel side allocations call drm_buffer_object_create() directly and can still specify drm_bo_type_kernel. Not 100% this makes sense either, but with this patch, the buffer type is no longer exported and we can clean up the internals later on.

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.

2007-08-02Remove the pinned buffer from the LRU when pinning.Eric Anholt
Also, be a little safer with setting the pinned flag within the struct lock. I'm not 100% sure if this is required, but it seems like it might be.
2007-08-02Add a couple of doxygen comments from reading the code.Eric Anholt
2007-07-26Copy the important parts of object_validate into object_create().Eric Anholt
This should let us allocate buffers without holding the hardware lock. While here, add DRM_DEBUG info for the drm_bo ioctls, so you can see something more specific than just the cmd value per ioctl.
2007-07-26Replace NO_MOVE/NO_EVICT flags to buffer objects with an ioctl to set pinning.Eric Anholt
This cleans up the create/validate interfaces for this very uncommon path, and makes pinned object creation much easier to use for the X Server.
