this probably needs further cleanup (just getting a surface for the resource
seems quite nonoptimal and potentially cause unnecessary copies I think)

Faster, simpler and more flexible.

Also, we set those flags properly on nv3x so that we don't allocate buffers in GART.

Since on AGP GART is uncached, OpenGL doesn't distinguish between vertex and index buffers, and we don't support hardware index buffers for now, this caused uncached reads.

Also check bind and not usage for PIPE_BIND_* flags, got broken in the gallium-resources transition.

Just a dumb buffer, allowed by the RING_3D/fixed subchannel binding and
no support for relocations.

This is *much* faster than state objects.

Autobinding creates additional pushbuffer usage which may not be
accounted in callers, and is also slow.

The next relocations patch depends on this for correctness.

Assert instead if the objects are not bound, which should happen at
screen creation time.

RING_3D creates a method start for subchannel 7.

Bind the 3D engine to a fixed subchannel to make it work

This is much faster than the old BEGIN_RING, since we don't need
to waste cycles trying to "autobind" stuff, when a fast static binding
is perfectly good.

Subchannel 7 is chosen because the kernel takes up the lowest ones.

    util: fix up several uses of pipe_map_buffer_range

    This function used to return a pointer to where the start of the
    actual buffer would have been, even though only the requested range is
    being mapped.

    In the resources change, the function was modified to use a transfer
    internally, and started returning the pointer to the beginning of the
    transfer, ie the mapped range.

    Some users of the function were changed to reflect this new behaviour,
    some were not.  Since then the function has reverted to its original
    behaviour, matching master.

    This change restores some of the users of the map_buffer_range helper
    to expect the old/original behaviour.

    nvfx: fix for gallium-resources

    It seems to work with basic applications but almost surely needs more work.

    In particular, it probably shouldn't use PIPE_BUFFER_USAGE_* flags
    and should use PIPE_TRANSFER_* in several places.

    Also, we probably don't want the vtable indirect calls and that ought
    to be replaced with something better instead.

    util: restore u_simple_screen, nouveau still relies on it

commit 961cbcb622
Author: Keith Whitwell <keithw@vmware.com>
Date:   Sun Mar 21 16:51:54 2010 +0000

    nouveau: convert nvfx and nv50 to pipe_resources

    Compile tested only.

    This was a deeper change than I was hoping for, due to the
    layering of the pipe_texture implementation in each driver on
    top of a shared pipe_buffer implementation in the shared code.

    Have modified the shared code to act as a set of convenience
    routines operating on nouveau_bo objects.

    Each driver now uses the u_resource_vtbl technique to split the
    implementation of pipe_resources between the existing miptree code
    for textures and a new, minimal buffer implementation in each
    driver.

    Eventually these should be combined, not least because APIs are now
    allowing things like binding buffer resources as textures and render
    targets.

    drm/r300: update for r300g pipe_resources conversion

    Remove old files that related to pipe_buffers but weren't being
    built.  Hopefully this is correct.

    r300: convert to pipe_resources

    Do a very shallow conversion - basically keeping the existing
    buffer and texture code intact and using a vtbl struct
    inside our resource struct to select between the two implementations.

    The buffer and texture treatments could be further merged without
    much effort, but try to keep the existing code working at this point.

And fix nv50_screen.c to compile against the updated header.

It is only used on pre-nv50 and nvfx is the only Gallium pre-nv50 driver.

The primitive splitting code is totally broken and will be rewritten.

Fix the most important bug now though.

The files have the same structure but are substantially different.

They are unified with appropriate conditionals.

    glx: permit building with older protocol headers

    I'd like to be able to build mesa on current distro releases without
    having to upgrade from the standard dri2proto and glproto headers.  With
    this change I'm able to build on ancient releases such as Ubuntu 9-10...

    In general, it would be nice to be able to build-test mesa to check for
    unintended breakages without having to follow the external dependencies
    of every group working on the codebase.

    No longer needed, except for nouveau and egl/xll/native_ximage.c.

    Fix for nouveau is to keep the call, but move it to an internal

    Fix for that egl/x11 relies on gallium-sw-api branch or its successor.

nouveau/ dri st / vmware

- The previous solution was hacky and didn't do subchannel autobinding.
- The beheaviour should match what libdrm_nouveau does closely.
- The solution remains statically sized, but when debugging is on it will check
for abuse.

- This avoids problematic "reloc'ed while mapped" messages and
some associated corruption as well.

- unreference state objects so that buffer objects are unreferenced and
eventually destroyed
- free channel at screen's destruction

Based on Krzysztof Smiechowicz's patch.

I just coded a patch that does this and seems to work fine. It must be
fixed since it breaks OpenGL (or the state tracker can be changed, but
it seems better to do it in the driver).

The patch also fixes NV20 and NV30 in the same way. They compile but
are untested.

I would guess that using the 3D engine is faster for the larger
levels, but the 2D engine is faster for the smaller ones (and lacks
this issue).

- Added flush notify functions for NV30 and NV40.
- Flushing mid frame will call flush notify, which will resubmit all
relocs.
- We don't try to recover from reloc failure yet.

The winsys once again has to know about textures it seems, so we need a
common representation between all our pipe drivers to store some
information the winsys will need.

Only the nv50 driver has been fixed so far.

libdrm_nouveau is linked with the winsys, there's no good reason to do all
this through yet another layer.

drm_api is a set of hooks used by the dri2 state tracker, this wraps our
dri1 code around the same set of hooks.

Currently the dri2 build will produce nouveau_dri2.so which you'll need
to install as nouveau_dri.so if you wish to try it.  The dri2 state
tracker doesn't make it easy for a driver to support both paths in the
same binary.

The core reference counting code is centralized in p_refcnt.h.

This has some consequences related to struct pipe_buffer:

* The screen member of struct pipe_buffer must be initialized, or
  pipe_buffer_reference() will crash trying to destroy a buffer with reference
  count 0. u_simple_screen takes care of this, but I may have missed some of
  the drivers not using it.
* Except for rare exceptions deep in winsys code, buffers must always be
  allocated via pipe_buffer_create() or via screen->*buffer_create() rather
  than via winsys->*buffer_create().
