We were putting the source pointer in a register used as a temporary,
breaking all paths that don't read the data in a single instruction.

check_os_katmai_support checks that the operating system running on a
SSE-capable processor supports SSE. This is necessary for unpatched
2.2.x and earlier kernels. 2.4.x and later kernels support SSE.
check_os_katmai_support will disable SSE capabilities for 32-bit x86
operating systems for which there is no code path. Currently, this
function handles Linux, Windows, and several BSDs. Mac OS, Cygwin, and
Solaris are several operating systems with no code paths.
Rather than add code for the unhandled operating systems, remove this
function altogether. This will fix SSE detection on all recent 32-bit
x86 operating systems. This completely breaks functionality on unpatched
2.2.x and earlier kernels, although there are likely no Gallium3D users
on such operating systems.

Assuming the side-effect of x86_make_reg is also unnecessary.

Non-portable.

Changes in v2:
- Change function name
Currently draw_llvm refuses to create itself on non-SSE2 CPUs due to
an alleged LLVM bug.
However, this is implemented improperly, because other parts of draw
still attempt to access draw->llvm, resulting in segfaults.
Instead, put the check in debug_get_option_draw_use_llvm, check that
before calling draw_llvm_create, and then check whether draw->llvm is
non-null everywhere else.

NOTE: Win64 is untested, and is thus currently disabled.
If you have such a system, please enable it and report whether it works.
To enable it, change src/gallium/auxiliary/translate/translate.c
Changes in v5:
- On Win64, preserve %xmm6 and %xmm7 as required by the ABI
- Use _WIN64 instead of WIN64
Changes in v4:
- Use x86_target() and x86_target_caps()
- Enable translate_sse in x86-64, but not in Win64
Changes in v3:
- Win64 support (untested)
- Use u_cpu_detect.h constants instead of #ifs
Changes in v2:
- Minimize #ifs
- Give a name to magic number CHANNELS_0001
- Add support for CPUs without SSE (only memcpy and swizzles, like non SSE2)
- Fixed comments
translate_sse is currently very limited to the point of
being useless in essentially all cases.
In particular, it only support some float32 and unorm8
formats and doesn't work on x86-64.
This commit rewrites it to support:
1. Dumb memory copy for any pair of identical formats
2. All formats that are swizzles of each other
3. Converting 32/64-bit floats and all 8/16/32-bit integers to 32-bit float
4. Converting unorm8/snorm8 to snorm16 and uscaled8/sscaled8 to sscaled16
5. Support for x86-64 (doesn't take advantage of it in any way though)
This new translate can even be useful to translate index buffers for
cards that lack 8-bit index support.
It passes the testsuite I wrote, but note that this is a major change, and more
testing would be great.

Changes in v5:
- Add sse2_movdqa
Changes in v4:
- Use _WIN64 instead of WIN64
Changes in v3:
- Add target and target caps functions, so that they could be different in
principle from the current CPU and they don't need #ifs to check
Changes in v2:
- Win64 support (untested)
- Use u_cpu_detect.h constants instead of #ifs
This commit adds minimal x86-64 support: only movs between registers
are supported for r8-r15, and x64_rexw() must be used to ask for 64-bit
operations.
It also adds several new instructions for the new translate_sse code.

Currently, only 32-bit indices are supported, but some use cases
translate needs support for all types.
|
|
Currently translate_sse puts two trivial wrappers in the translate vtable.
These slow it down and enlarge the source code for no gain, except perhaps
the ability to set a breakpoint there, so remove them.
Breakpoints can be set on the caller of the translate functions, with no
loss of functionality.
|
|
This moves the common code into a separate ALWAYS_INLINE function.

Changes in v3:
- If we can do a copy, don't try to get an emit func, as that can assert(0)
Changes in v2:
- Add comment regarding copy_size
When used in GPU drivers, translate can be used to simultaneously
perform a gather operation, and convert away from unsupported formats.
In this use case, input and output formats will often be identical: clearly
it would make sense to use a memcpy in this case.
Instead, translate will insist to convert to and from 32-bit floating point
numbers.
This is not only extremely expensive, but it also loses precision for
32/64-bit integers and 64-bit floating point numbers.
This patch changes translate_generic to just use memcpy if the formats are
identical, non-blocked, and with an integral number of bytes per pixel (note
that all sensible vertex formats are like this).

Fix a copy-and-paste error introduced by
f141abdc8fdbff41e16b0ce53fa3fa8fba32a7f9.

Triangle strip alternates the front/back orientation of its triangles.
max_vertices was made even so that varray never splitted a triangle
strip at the wrong positions.
It did not work with triangle strips with adjacencies. And it is no
longer relevant with vsplit.
|
|
The higher bits of draw elements are no longer used for the stipple or
edge flags.
|
|
PRIMITIVE is used by the indexed path to flush the entire primitive with
custom vertex count checks. It replaces the existing fast path.
|
|
That is, OpenGL decomposition rule is assumed. There should be a
pipe_context state to specify the rules.
|
|
They have been deprecated by vsplit.
|
|
vcache decomposes primitives while vsplit splits primitives. Splitting
is generally easier to do and is faster. More importantly, vcache
depends on flatshade_first to decompose. The outputs may have incorrect
vertex order which is significant to GS.
|
|
vsplit is a superset of varray. It sets the split flags comparing to
varray.
|
|
vsplit is based on varray. It sets the split flags when a primitive is
splitted. It also has support for indexed primitives.
For indexed primitives, unlike vcache, vsplit splits the primitives
instead of decomposes them.
|
|
draw_pt_trim_count is renamed from trim in draw_pt.c.
|
|
The run method is simplified to take the start vertex and the vertex
count.
|
|
Update the middle end interface to pass the primitive flags from the
frontends to the pipeline. No frontend sets the flags yet.
|
|
A primitive may be splitted in frontends. The splitted primitives
should convey certain flag bits so that the decomposer can correctly
decide the stipple or edge flags.
This commit adds flags to draw_prim_info and updates the decomposer to
honor the flags. Frontends and middle ends will be updated later.

This commit silences the printing off most of the debug information
when running debug builds. The big culprits are: the tgsi sanity checker
that gets run on all shaders on debug; all the options; and
finaly the cpu caps printer.

This logic duplicates the one in p_config.h, so remove it and adjust
the only two places that were using it.

It causes a very ugly corruption on the Earth's halo on Google Earth.

This reverts commit de4784e36505316c2a5ab34cc5b371d17f38d3c5.

No need to enable depth test for clear.

Currently translate asserts on unsupported output formats, making
it impossible to use for some purposes, such as testing whether it
actually works on all formats it supports.
Removing the assert was met with opposition, so this change allows
clients to ask whether an output format is supported, and they are thus
able to avoid attempting to use it.
Since this is just an addition to the API, no adverse effect is
possible, and it makes the testsuite work again.

Fixes MSVC build.

This is a follow-up to commit b85c71d4e1e4ed788be834dff5b7b3c0cd0402ac
which added u_staging.c to make.

Thanks to Michal for spotting this.

This reverts commit 16b45ca7cefb3432b4133fe9d0b1dbfe3f286131.
José Fonseca asked for a revert.
Note that the testsuite will now segfault since it attempts to test
all possible formats.
|
|
translate was attempting to output A8R8G8B8_UNORM as if it were
R8G8B8A8_UNORM.
Now the tests just added pass.
|
|
This gives the caller a chance to recover (or crash anyway otherwise).
|
|
util_framebuffer_copy was attempting to copy all elements of the
source framebuffer state.
However, this breaks if the user does not zero initialize the structure.
Instead, only copy the elements up to nr_cbufs, and clear elements up
to dst->nr_cbufs, if the destination was larger than the source.
|

Single divide, so let lp_build_div decide how to implement this.
This will save a multiplication in architectures which don't have
a RCP intrinsic.

Texture dimensions are unsigned.

Direct3D 10/11 has no concept of transfers. Applications instead
create resources with a STAGING or DYNAMIC usage, copy between them
and the real resource and use Map to map the STAGING/DYNAMIC resource.
This util module allows to implement Gallium drivers as a Direct3D
driver would be implemented: transfers allocate a resource with
PIPE_USAGE_STAGING, and copy the data between it and the real resource
with resource_copy_region.

Used to find out if a surface exists without creating one.

|
Using cso_hash directly is the right thing since util_hash_table
adds useless overhead and is harder to use for this application.
|
|
|
|
They are unimplemented, even though the framework makes it possible to
implement them well, and nv50 needs them.
|
|
Current practice is to start identifiers with "util_" instead of "u_".
