For driver performance analysis it usefull to be able to
disable as much as possible the GPU interaction so that
one can profile the userspace only.

Fixes crash in piglit depthrange-clear.

These were previously being left in the default (D3D) mode. This mean
that triangles were drawn slightly incorrectly, but also because this
state is relied on by the u_blitter code, all blits were half a pixel
off.

This opens the question of what interface the winsys layer should
really have for talking about these concepts.
For now I'm using the existing gallium resource usage concept, but
there is no reason not use terms closer to what the hardware
understands - eg. the domains themselves.

That way assert(map_count >= 0) can actually fail when we screwed up.

This ensures that we increase bo->map_count when radeon_bo_map_internal()
returns successfully, which in turn makes sure we don't decrement
bo->map_count below zero later.

radeon_bo_destroy() will want to read the list field. Without this patch,
we'd end up evaluating the list pointers before they have been properly
set up when we destroyed the newly created bo if it cannot be mapped.

we need to know if the back is tiled so we can blit from it properly.

Would try to destroy radeon->cman, radeon->kman both which were still
NULL.

Since flush rework there could be only one relocation per
register in a block.

Got a speed up by tracking the dirty blocks in a seperate list instead of looping through all blocks. This version should work with block that get their dirty state disabled again and I added a dirty check during the flush as some blocks were already dirty.

Flush read cache before writting register. Track flushing inside
of a same cs and avoid reflushing same bo if not necessary. Allmost
properly force flush if bo rendered too and then use as a texture
in same cs (missing pipeline flush dunno if it's needed or not).

Allow fast lookup of relocation information & id which
was a CPU time consumming operation.

if we know the bo has gone not busy, no need to add another bo wait
thanks to Andre (taiu) on irc for pointing this out.
|
|
since we plan on using dx10 constant buffers everywhere.
|
|
we don't use this since constant buffers are now being used on all gpus.
|
|
When we go to do a lot of bos in one draw like constant bufs we need
to avoid bouncing off the busy ioctl, this mitigates by backing off
on busy bos for a short amount of times.
|
|
this just keeps a list of bos submitted together, and uses them to decide
bo busy state for the whole group.

Add bo offset everywhere needed if r600_bo is ever a sub bo

no wonder it was slow, the code is deliberately forcing stuff into GTT,
we used to have domain management but it seems to have disappeared.
|
|
|
|
this function was taking quite a lot of pointless CPU.
|
|
this sets up a single loop constant like r600c does.
|
|
|
|
just a typo in the register headers.

this gets rid of lots of the instability on evergreen,
which isn't surprising since it really broken not to flush caches.
|
|
we'll need this for color tiling on evergreen.
|
|
These need to be emitted, we also need them to do proper vtx start,
instead of abusing index offset.

Save a lot of call into the kernel and thus improve performances.

This avoid to overcount the number of dwords we need and
thus avoid maximazation of cs buffer use.
