Basically no change relative to hard-coded version, but this will
be useful for other changes later.

The variables are used in code that is currently ifdef'ed out.

Winsys context build a list of register block a register block is
a set of consecutive register that will be emited together in the
same pm4 packet (the various r600_block* are there to provide basic
grouping that try to take advantage of states that are linked together)
Some consecutive register are emited each in a different block,
for instance the various cb[0-7]_base. At winsys context creation,
the list of block is created & an index into the list of block. So
to find into which block a register is in you simply use the register
offset and lookup the block index. Block are grouped together into
group which are the various pkt3 group of config, context, resource,
Pipe state build a list of register each state want to modify,
beside register value it also give a register mask so only subpart
of a register can be updated by a given pipe state (the oring is
in the winsys) There is no prebuild register list or define for
each pipe state. Once pipe state are built they are bound to
the winsys context.
Each of this functions will go through the list of register and
will find into which block each reg falls and will update the
value of the block with proper masking (vs/ps resource/constant
are specialized variant with somewhat limited capabilities).
Each block modified by r600_context_pipe_state_set* is marked as
dirty and we update a count of dwords needed to emit all dirty
state so far.
r600_context_pipe_state_set* should be call only when pipe context
change some of the state (thus when pipe bind state or set state)
Then to draw primitive you make a call to r600_context_draw
void r600_context_draw(struct r600_context *ctx, struct r600_draw *draw)
It will check if there is enough dwords in current cs buffer and
if not will flush. Once there is enough room it will copy packet
from dirty block and then add the draw packet3 to initiate the draw.
The flush will send the current cs, reset the count of dwords to
0 and remark all states that are enabled as dirty and recompute
the number of dwords needed to send the current context.

this add support for the upload manager for uploading user vbo/index buffers.
this provides a considerable speedup in q3 type games.
|
|
this moves to using a pb bufmgr instead of kernel bos directly.
|
|
this paves the way for moving to pb bufmgrs now.
|
|
introduce an abstraction layer between kernel bos and the winsys BOs.
this is to allow plugging in pb manager with minimal disruption to pipe driver.
|
|
no need for this info to be exported to pipe driver.

Allows disabling various operations (mainly texture-related, but
will grow) to try & identify bottlenecks.
Unlike LP_DEBUG, this is active even in release builds - which is
necessary for performance investigation.

This is likely only correct for OpenGL and not other state trackers.

We would leak the newly created bo if it cannot be mapped.

since the depth blit code is hardcoded hex yay \o/

This whole set of state just seems wrong, another cut-n-paste nightmare.

more prep work for fixing up buffer handling
|
|
we need this for future buffer rework, it also makes the vtbl easier

Using non-int types for bitfields is a gcc extension.
The size of the struct is not effected by this change.

Avoid using r600_screen structure to get ptr to radeon
winsys structure.

Execute before folding loads, because we don't check if it's legal
in lower_mods.
Ensure that a value's insn pointer is updated when transferring it
to a different instruction.

Bad rebase presumably.

The code that uses dname is currently ifdef'ed out.
