Took care of the remaining substantive differences. Still many
formatting/commenting differences. Version set to 47.1 to indicate
some post-47 additions.

These directories build and are partially turned-on on Windows, using the "tri"
demo (follow-on commit) and a "NULL driver" that was created out of the
sample/Intel driver. The GetProcAddress() is not yet finding symbols in the
NULL driver.
For now:
- "C:\Windows\System32" is the default XGL driver directory. The getenv()
isn't yet working. I suggest creating your own #define in order to point to
where a driver is.
- In order to recognize a Windows driver, we must look at both its prefix and
suffix (i.e. it is named "XGL_*.dll", e.g. "XGL_i965.dll).
- We autogenerate Windows ".def" files for the layers. Additional info is:
- This is necessary in order for a DLL to export symbols that can be queried
using GetProcAddress(). We can't use the normal Windows approach of
declaring these functions using "__declspec(dllexport)", because these
functions are declared in "xgl.h".
- This involves adding and running the new "xgl-win-def-file-generate.py"
file.
- NOTE: Layers don't have the xglInitAndEnumerateGpus() entrypoint, just the
xglGetProcAddr() entrypoint (and now the xglEnumerateLayers() entrypoint).
Generating them is pretty simple.
NOTE: In order to build on a 64-bit Windows 7/8 system, I did the following:
- Install VisualStudio 2013 Professional
- Install CMake from: http://www.cmake.org/cmake/resources/software.html
- I let it add itself to the system PATH environment variable.
- Install Python 3 from: https://www.python.org/downloads
- I let it add itself to the system PATH environment variable.
- Obtain the Git repository, checkout the "ian-150127-WinBuild" branch.
- Using a Cygwin shell: I did the following:
- "cd" to the top-level directory (i.e. the one that contains the ".git"
directory).
- "mkdir _out64"
- "cd _out64"
- "cmake -G "Visual Studio 12 Win64" .."
- At this point, I used WindowsExplorer to open the "XGL.sln" file. I can
build. CMake causes the build shortcut to be "Ctrl-Shift-B" instead of the
normal "F7". I had to right-click the "ALL_BUILD" project, go to
Properties->Debugging and change the debug Command and Working Directory to
point to "tri.exe" and where the executable are. At this point, I can debug
(using the normal "F5" shortcut).

This is part of rev 47 but was accidentally skipped.
|
|
Misspelled a parameter name, fixup for header cplusplus definition.
|
|
|
|
Also they do the same init and removal as existing InitAndEnumerateGpus.
|
|
For now, retain the existing InitAndEnumerateGpus and have it create one
instance. New APIs aren't fully implemented yet in driver or loader.
|
|
Arrays of MemBarrier pointers were incorrectly declared. Reference
bug #13273, for xgl header rev #42.
|
|
Part of moving to xgl.h rev#38, svn rev 29293-29302
|
|
Miscellaneous updates for SVN revs 29191, 29205 and 29241. Basically
adding MAX_ENUM, copyright notices, and improved type definitions.
|
|
|
|
Added new APIs for optimized clears of color and depth buffers.
Bug# 13172, due to a bug in rev39, this also accounts for the change
in rev41.

Alpha header rev: r29437
Bug #13299
|
|
alpha header version: r29593
XGL_RESULT is the XGL return codes.
Agreement part of F2F Jan 26, 2015.
|
|
|
|
Add default values if no attachments are present, correctly handle
override values when attachments are present. Bug# 13212, header
revision #36.
|
|
|
|
Cosmetic change to xgl header for rev# 37, bug# 13244.
|
|
For svn rev# 29226, generalized an XGL_WAIT_EVENT enum.
|
|
Bug #: 12997
Alpha header revision: r29249
|
|
Implement changes for alpha header version 0.35.
Bug #12998.
|
|
Cosmetic xgl header change for xgl.h revision #40.
|
|
Also reorder memory_alloc_info struct as memPriority added back in as last
member in struct.

For now it is always index 0. Updates, driver, glave, tests, demos, include,
and layers.
|
|
|
|
All except layout(set=) is supported. The change to
pipeline_compiler_interface.{cpp,h} is ugly and fragile. It should be fixed
after adding layout(set=) support.
|
|
Update xgl.h (cosmetic changes only). Add support for new formats.
v2: fix blit tests and enhance xglinfo for new formats
|
|
|
|
Added resource transition proposal from Bug 12904.
Updated function prototypes.
Added XGL_IMAGE_CREATE_MUTABLE_FORMAT_BIT based on Intel's request.
Unless this flag is specified, image views created from the image must match the base format.
xgl.py: changes for resource tracking

Bump version patch number also.
|
|
Omit changes for now that alter existing APIs: xglcmdBindAttachments and
xglBeginCommandBuffer
Bump the API version patch number, since we are diverging our version numbers
from the SVN history. This is necessary since we are not implementing header
changes in the same order they were added to SVN header.
|
|
|
|
While this branch is divereged from Khronos SVN sequence of xgl.h versions.
Any ABI change in this branch should increment the patch number: XX.YY.ZZ++.
Glave relies on the xgl.h version number to track trace file compatibility.
|
|
Switched EnumerateLayer parameter order, added conditional definition
of xgl function prototypes, and prepended 'xgl' to all function
prototypes. This included fixes for bugs #13173 and #13180.
|
|
Layers can now call getLayerOption("<option name>") to get layer settings.
File xgl_layer_settings.txt can be used to provide option and value pairs
to configure a given layer.
Add enums to xglLayer.h to provide a generic ACTION and LEVEl settings for
options in the settings file.
|
|
Use what was in the upstream header. The switch of XGL_SIZE to size_t
generates quite some warnings and is fixed.
|
|
This change modifies xgl.h to include a new descriptor set
slot type for textures, distinct from resources:
XGL_SLOT_SHADER_TEXTURE_RESOURCE
Buffers continue to use:
XGL_SLOT_SHADER_RESOURCE
The ordering of their inclusion in binding tables entries is
important: textures must come before buffers. This is how
the compiler expects them to be laid out.
