util: Cleanup u_cpu_detect, build. Support X86_64 and detect SSE4.1 too.
I was waiting for the need to use this code to arise, and it finally came.
I've tested building this on Linux and Windows, both x86 and x64_64. But
it might break other platforms. Please bear with me and help me fix it.
Many thanks to Dennis Smit who submitted this, and Eric Anholt whose
work this was based on.
util: Auto generate pixel format accessor functions from
This has several advantages over the u_
- not hand written
- no intermediate memcpy of raw pixels
- supports 4 ubytes in addition to floats
- no need to pass a pipe_transfer
It also has (hopefully temporary) limitations:
- no support for YUV
- no support for SRGB
There are some inconsistencies in pipe_format, but above all, there
simply aren't enough bits in an enum to conveniently store all
information about a pixel format we need to be able to dynamically
generate pixel packing/unpacking code.
Add a module that will manage uploading and coalescing multiple
user-buffers, malloc-buffers and other random data that doesn't
happen to be in a GPU buffer already. The module stuffs multiple
little uploads into larger GPU buffers to reduce create/destroy
overheads, etc.
The template makefile that most libraries in
gallium included was based on dri and had a bunch
unrelevant junk in it.
Update it and improve the depending makefiles.
Code reorganization: split gallium and mesa makefiles.
In other words, don't build src/gallium source code from within src/mesa/Makefile.
Also, allow to customize which gallium auxiliary dirs, driver driver, winsys
dirs get built from the config/* files.
Update the Makefiles and includes for the new paths.
Note that there hasn't been no separation of the Makefiles yet, and make is
jumping all over the place. That will be taken care shortly. But for now, make
should work. It was tested with linux and linux-dri. Linux-cell and linux-llvm
might require some minor tweaks.
First pass at a fallback concept for pipe devices.
Creates a new pipe driver that feeds commands to either a hardware or
software pipe depending on fallback state.
Untested concept checkpoint. At this point it compiles.
