* mesa: Rename the CEILING() macro to DIV_ROUND_UP().Francisco Jerez2015-02-101-1/+1
| | | | | | | | | | Some people have complained that code using the CEILING() macro is difficult to understand because it's not immediately obvious what it is supposed to do until you go and look up its definition. Use a more descriptive name that matches the similar utility macro in the Linux kernel. Reviewed-by: Matt Turner <[email protected]>
* mesa: Replace IS_NEGATIVE(x) with x < 0.0f.Matt Turner2014-09-251-7/+0
| | | | | | | | I only made IS_NEGATIVE(x) use signbit in commit 0f3ba405 in an attempt to fix 54805, but it didn't help. We didn't use signbit on some platforms and instead defined it to x < 0.0f. Reviewed-by: Kenneth Graunke <[email protected]>
* mesa: fix UNCLAMPED_FLOAT_TO_UBYTE() macro for MSVCBrian Paul2014-09-101-4/+4
| | | | | | | | | | MSVC replaces the "F" in "255.0F" with the macro argument which leads to an error. s/F/FLT/ to avoid that. It turns out we weren't using this macro at all on MSVC until the recent "mesa: Drop USE_IEEE define." change. Reviewed-by: Roland Scheidegger <[email protected]>

* mesa: Drop USE_IEEE define.Matt Turner2014-08-071-1/+1
| | | | | | | | | | | | | I think OpenVMS was the only platform that Mesa ran on that used a non-IEEE representation for floats. We removed OpenVMS support a while back, and this should alleviate the need to continue updating the this-platform-uses-IEEE list. The one bit of this patch that needs review is the IS_INF_OR_NAN, because I'm not sure if MSVC supports isfinite.

| | | | | | | | | | Silence a bunch of MSVC type conversion warnings. Changed return type of S_FIXED to int32_t (signed). The result is the same. It just seems more intuitive that a signed conversion function should return a signed value. Reviewed-by: Jose Fonseca <[email protected]>
* mesa: Move U_FIXED/S_FIXED macros from i965 to macros.h.Kenneth Graunke2013-10-131-0/+22
| | | | | | | | | | | | | | | | | These make it easy to convert a floating point value to a fixed point numbers. The second parameter is the number of bits used for the fractional part of the number. It looks like core Mesa has similar functions already, but none that allows an arbitrary number of fractional bits. The more generic version is probably useful to everyone. r600g apparently has an identical copy of the S_FIXED macro, but doesn't include this file. I'm not sure what to do about that, so I'm just going to leave it for now. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE in macros.h computed incorrect results for inputs in the range 0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875) inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5 when multiplied by 255. With rounding mode "round to closest even integer", this is the largest float in the range 0.0-1.0 that is converted to 254 by the generic implementation of UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000 (=255.0/256.0). The same bug was present in the function float_to_ubyte in u_math.h. Fix: The proposed fix replaces the incorrect cut-off value by 0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81 (or any value in between) would also work, but 1.0f is probably cleaner. The patch does not regress piglit on llvmpipe and on i965 on sandy bridge.

| | | | | | | | | | | | | | | | | | | | | Previous to this patch, there were 13 identical definitions of this macro in Mesa source. That's ridiculous. This patch consolidates 6 of them to a single definition in src/mesa/main/macros.h. Unfortunately, I wasn't able to eliminate the remaining definitions, since they occur in places that don't include src/mesa/main/macros.h: - include/pci_ids/pci_id_driver_map.h - src/egl/drivers/dri2/egl_dri2.h - src/egl/main/egldefines.h - src/gbm/main/backend.c - src/gbm/main/gbm.c - src/glx/glxclient.h - src/mapi/mapi/stub.c I'm open to suggestions as to how to deal with the remaining redundancy.

* vbo: fix glVertexAttribI* functionsMarek Olšák2012-11-061-0/+39
| | | | | | | | | | | | | | | | | | | | | | The functions were broken, because they converted ints to floats. Now we can finally advertise OpenGL 3.0. ;) In this commit, the vbo module also tracks the type for each attrib in addition to the size. It can be one of FLOAT, INT, UNSIGNED_INT. The little ugliness is the vertex attribs are declared as floats even though there may be integer values. The code just copies integer values into them without any conversion. This implementation passes the glVertexAttribI piglit test which I am going to commit in piglit soon. The test covers vertex arrays, immediate mode and display lists. NOTE: This is a candidate for the stable branches. Reviewed-by: Brian Paul <[email protected]> v2: cosmetic changes as suggested by Brian
