2018-06-06Add versioningHEADmasterLeo (Sunpeng) Li2-3/+16
2018-06-06Change name of executable to cmdemoLeo (Sunpeng) Li3-4/+4
`demo` is too vague.
2018-05-31Use 32-bit format for CTMLeo (Sunpeng) Li1-9/+31
Using 32-bits isn't the best, but it better represents the S31.32 format than 16-bit. 64-bit is desired, since each CTM element is S31.32 format, but there's no xserver support for it. We can use the first 32 bits to represent the S31 signed- magnitude whole component, and the second 32 bits to represent the fractional component. See the comments in set_ctm() for details.

2018-05-31Add randr format enumLeo (Sunpeng) Li1-13/+23
For use when setting randr property blobs. This is sort of a revert of: 908098f30 Hardcode 16 bit format into set_output_blob() This is done in preparation of using 32-bit format for CTM. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
2018-05-11Remove libdrm includesLeo (Sunpeng) Li1-9/+7
We really shouldn't be dependant on libdrm anyways. Also switch linux int types to C standard int types. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
2018-05-11Revert "Use DRM's color LUT/CTM structs"Leo (Sunpeng) Li1-6/+24
We can get rid of xf86drm.h includes. It's a better way of showing that we don't depend on libdrm anymore. This reverts commit 88cb2a6ec6d4b39349c68ecd5057750d99305bdd.
2018-05-11Remove code that opens DRM file descriptorLeo (Sunpeng) Li1-63/+11
With the 2nd revision of the interface, we do not need to open the DRM fd. We were previously using it to create a DRM blob, but thats not necessary anymore. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
2018-05-10Hardcode 16 bit format into set_output_blob()Leo (Sunpeng) Li1-9/+19
All blob properties are currently using 16 bits, due to some issues with the RandR extension. Just hard-code it for now, for clarity. Add some comments explaining that as well. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
2018-05-02Use DRM's color LUT/CTM structsLeo (Sunpeng) Li1-24/+6
They're already included via xf86drm.h Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
2018-05-02Stop managing DRM blobs, the DDX driver manages that nowLeo (Sunpeng) Li2-55/+27
The DDX driver manages creation of DRM blobs. We just pass a pointer to an array containing the LUT/CTM data. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>

2018-05-02Build to root dir instead.Leo (Sunpeng) Li2-4/+5
The build dir was suppose to contain any compiled objects for easy gitignoring. However, only we only ended up with one executable. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
2018-05-02Implemented demo app for degamma, ctm, and regamma.Leo (Sunpeng) Li1-74/+434
The app currently uses a system call to xrandr to set the blob IDs. Ideally, we should include libxrandr, and use the library to do so instead. Signed-off-by: Leo (Sunpeng) Li <sunpeng.li@amd.com>
