This driver does no transformation of the gallium calls
going to the real driver, like the identity matrix. It is
intended to be the basis for transforming and/or debug
drivers like trace and rbug.
Authors of this patch are:
Michal Krol, orignal heavy lifting.
José Fonesca, object wrapping code stolen from trace.
Jakob Bornecrantz, put it all toghether and renamed a stuff.
intel: Avoid trying to do blits to Y tiled regions.
This is somewhat nasty, but we need to do Y-tiled depth for FBO support.
May help with corruption and hangs since enabling texture tiling, and
since switching depth textures to Y tiled.
Fixes piglit depthtex.c on 965.
mesa: From float type modifier from values to large for singles
The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.
intel: Don't map regions with drm_intel_gem_bo_map_gtt() unless they're tiled.
This fixes a regression in region read performance that came in with the
texture tiling changes. Ideally we'd have an access flag coming in so we
could also use bo_map_gtt for writing, like we do for buffer objects.
Bug #22190
The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.
mesa: Make VBO dlist printing use the same path as other dlist printing.
I was rather confused when mesa_print_display_list didn't show any of
my glBegin()..glEnd(). Nothing but print_list appears to call
this function, so matching its behavior seems like a good idea.
intel: Do not access pbo's buffer directly when attaching.
pbo might be system buffer based or attached to another region. Call
intel_bufferobj_buffer to make sure pbo has a buffer of its own.

intel: Fix migration from sys_buffer in intel_bufferobj_buffer.
intel_bufferobj_subdata is called to migrate data from sys_buffer, and
it expects only one of buffer or sys_buffer is non-NULL.

need to pass target parameter to radeon_teximage/radeon_subteximage functions
otherwise mipmap generation for cube maps can't work (assert/segfault in
_mesa_generate_mipmap)
intel: Fixups for 'mesa: create/destroy buffer objects via driver functions'.
Initialize all driver function hooks before calling _mesa_initialize_context(),
and handle all buffer objects in intel_buffer_object().
Fixes assertion failure when running glxinfo.
drm cmd checker would refuse cube emits
also fix an issue in the cs path which would calculate the register
offset off by one dword.
Only same testing done as original code (none except compile tested).
st/mesa: remove redundant st_buffer_object::size field and error checks
Just use the gl_buffer_object::Size field. Remove unnecessary size/offset
error checks. Core Mesa will have already done these checks before these
functions are called.
st/mesa: no longer special-case buffer object 0 in st_buffer_object() cast wrapper
Since commit 6629a35559 "mesa: create/destroy
buffer objects via driver functions" this is no longer needed, and actually
was causing a crash during context tear-down.
radeons: use dp4 for position invariant vertex programs
Fixes #22181. R200 requires this since DP4 is used in hw tnl mode.
R300 prefers it (should be faster due to no instruction dependencies), but
both methods should be correct (when sw tcl is used though, MUL/MAD might
be faster). Probably doesn't make much difference for R100 since vertex progs
are executed in software anyway, but let's just keep it the same there too.
