radeon_cs_space_check flushes the pipe context on failure, retries
the validation, and returns -1 if it fails again. At that point, there is
nothing we can do, so let's skip draw operations instead of getting stuck
in an infinite loop.
This code path ideally should never be hit.
|
|
This a leftover probably and is unnecessary, since we flush u_upload_mgr
in r300_flush.
|
|
|
|
Update all drivers to use draw_set_index_buffer,
draw_set_mapped_index_buffer, and draw_vbo. Remove
draw_set_mapped_element_buffer and draw_set_mapped_element_buffer_range.

Fixes this GCC warning.
r300_render.c: In function 'r300_draw_flush_vbuf':
r300_render.c:988: warning: unused variable 'r300_render'
|
|
the current code reuses the same vbo over and over, however after a flush
we'd stall and wait for mapping on the vbo when we should just fire and forget.
On a gears test this brings me from ~620 to ~750 on my rv530 in swtcl mode.

This implements fast Z clear, Z compression, and HiZ support for r300->r500
GPUs.
It also allows cbzb clears when fast Z clears are being used for the ZB.
It requires a kernel with hyper-z support.
Thanks to Marek Olšák <maraeo@gmail.com>, who started this off, and Alex Deucher at AMD for providing lots of hints.
v2:
squashed zmask ram size fix]
squashed r300g/blitter: fix Z readback when compressed]
v3:
rebase around texture changes in master - .1 fix more bits
v4:
migrated to using u_mm in r300_texture to manage hiz/zmask rams consistently
disabled HiZ when using OQ
flush z-cache before turning hyper-z off
update hyper-z state on dsa state change
store depthclearvalue across cbzb clears and replace it afterwards.

The Draw flush inside r300_flush was the culprit.
Also, no need to flush Draw when changing a state since the flush is
already inside swtcl_draw_vbo.

This fixes fdo bug #29286.
|
|
That is, remove pipe_context::draw_arrays, pipe_context::draw_elements,
pipe_context::draw_arrays_instanced,
pipe_context::draw_elements_instanced,
pipe_context::draw_range_elements.

Some drivers define a generic function that is called by all drawing
functions. To implement draw_vbo for such drivers, either draw_vbo
calls the generic function or the prototype of the generic function is
changed to match draw_vbo.
Other drivers have no such generic function. draw_vbo is implemented by
calling either draw_arrays and draw_elements.
For most drivers, set_index_buffer does not mark the state dirty for
tracking. Instead, the index buffer state is emitted whenever draw_vbo
is called, just like the case with draw_elements. It surely can be
improved.

It is a lot simplier, cleaner, and more stable now.
|
|
An initial implementation made by Dave Airlie.
For it to be used, a color-only clear must be invoked and exactly one
point-sampled render target must be set. The render target must be
macrotiled (for us to overcome alignment issues) and bpp must be either
16 or 32.
I can't see a difference in performance. :(

With an ordinary quad, the pixels on the main diagonal are computed
and stored twice, which is somewhat inefficient and might not work well
with specialized clear codepaths.

And other minor fixups.

Yay for old code.

There is a problem though, the translate module cannot emit half float
vertices.
|
|
The next step is to replace skipping by an actual fallback.

I admit blitting to/from GTT is actually enforced in this commit,
texture transfers are now damned fast!
|

It's now more separate from the rest of the driver and it can be disabled
by commenting out just 1 line. Well, I couldn't make the previous version
work with SW TCL reliably, that's the reason of this little rework.
