Make state statically allocated, this kills a bunch of code
and avoid intensive use of malloc/free. There is still a lot
of useless duplicate function wrapping that can be kill. This
doesn't improve yet performance, needs to avoid memcpy states
in radeon_ctx_set_draw and to avoid rebuilding vs_resources,
dsa, scissor, cb_cntl, ... states at each draw command.

add cube and shadow support to the texture code.
|
|
For some reason r600c, emits extra instructions in the FP to do the depth write output swizzle,
I'm not sure this is required, so here I'm doing it in the exports.
this fixes the mesa trivial demos tri-depthwrite and tri-depthwrite2, it doesn't fix
the glsl1 gl_FragDepth writing test however.

this fixes a few if the fs shader tests, 10 more piglits
|
|
|
|
this is a bit of a workaround, something is wrong with the literal emits here
so we just use the trig copy function to copy the immd to a temp at start of op.
fix VP/FP LIT tests
|
|
So as the trig functions used up the literal spots for the PI work, if the arg0 was an immediate
we'd hit failure, so copy the literal before starting.
add some tracking of max temp used to avoid trashing temp regs.
5 more piglits, fp1 COS,SCS,SIN tests

constant splitting was broken for multi-constant cases, fixes fp1 CMP+MAD, vp1 CMP.
|
|
|
|
Also add an error if we hit this problem again, we need to do this better
possibly tying the literal addition to the last flag.

The current states code had an unhealthy relationship between
that had to somehow magically align themselves, editing either
place meant renumbering all states after the one you were on,
and it was pretty unapproachable code.
This replaces the huge types structures with a simple type + sub
type struct, which is keyed on an stype enum in radeon.h. Each
stype can have a per-shader type subclassing (4 types supported,
PS/VS/GS/FS), and also has a number of states per-subtype. So you
have 256 constants per 4 shaders per one CONSTANT stype.
The interface from the driver is changed to pass in the tuple,
(stype, id, shader_type), and we look for this. If
radeon_state_shader ever shows up on profile, it could use a
hashtable based on stype/shader_type to speed things up.

passes another ~20 piglits.
/me starts to run out low hanging fruit around now.
|
|
passes glsl1-discard tests
|
|
8 more piglits, mainly the two SSG tests.
|
|
Adds BGNLOOP, BRK, CONT, ENDLOOP support, ported from r600c.
17 piglits more on r300g.tests.
|
|
Created an array for literals as we should not always use the last declared literal.

This reverts commit bd25e23bf3740f59ce8859848c715daeb9e9821f.
Apart from introducing a lot of hex magic numbers and being highly impenetable code,
it causes lots of lockups on an average piglit run that always runs without lockups.
Always run piglit before/after doing big things like this.

this adds handling for some more CF instructions and conditions
also adds parameter for stack size emission
These seem to pass on VS with the stack size hack but not on FS,
TODO: fix FS + stack size calcs
|
|
this makes op2 emission smaller, since it skips instructions
that don't write to the dst. not sure if this could have unwanted
side effects but try it and see.
|
|
though it isn't passing the test, and this instruction is pure bonghits.

Directly build PM4 packet, avoid using malloc (no states are
bigger than 128 dwords), remove unecessary informations,
remove pm4 building in favor of prebuild pm4 packet.

ported from r600c.

ported from r600c, fixes fp-cmp, glsl1-sqrt*

We need to always at least export one component (wether it's depth
or color. Add valid r7xx shader program for depth decompression.

Before using depth buffer as texture, it needs to be decompressed
(tile pattern of db are different from one used for colorbuffer
like texture)

Partialy fix texturing from depth buffer, depth buffer is tiled
following different tile organisation that color buffer. This
properly set the tile type & array mode field of texture sampler
when sampling from db resource.
Add initial support to untiling buffer when transfering them,
it's kind of broken by corruption the vertex buffer of previous
draw.

This pretty much ports the code from r600c, however it doesn't
always seem to work quite perfectly, but I can't find anything in this
code that is wrong. I'm guessing either literal input or constants
aren't working always.

the first two are straight op2's and the DDX/DDY are taken from r600c.
|
|
fixes fp-set-01 and glsl-fs-step
|
|
fixes biased texturing tests
|
|
Don't do perspective for TEX, and also copy input to a temporary for TEX
also add tex opcode names
|
|
makes glsl-fs-log2 and glsl1-integer division with uniform var pass
