* Remove _mesa_memset in favor of plain memset.Kenneth Graunke2010-02-191-1/+1
| | | | This may break the SUNOS4 build, but it's no longer relevant.
* swrast: fix broken _swrast_depth_clamp_span()Brian Paul2010-01-151-14/+27
| | | | | | | | | | The integer Z clamping range depends on the number of bits in the Z buffer because that's the scale factor used when we transform NDC coords by the viewport/depth range. Fixes fd.o bug #25972 but only for Z buffers up to a depth of 30 bits. Beyond that we get into messy integer overflow issues and things fall apart.

* mesa: Mostly fix swrast's ARB_depth_clamp support.Eric Anholt2009-10-291-9/+19
| | | | | | | I'd written a testcase for the hard part of the extension enablement, so naturally the easy stuff was completely broken. There are still issues, as I'm seeing FLOAT_TO_UINT(max_f) == 0x0 when max_f == 1.0, but it gets piglit depth-clamp-range closer to success.

| * mesa: remove a bunch of gl_renderbuffer fieldsBrian Paul2009-10-081-4/+9
| | | | | | | | | | | | _ActualFormat is replaced by Format (MESA_FORMAT_x). ColorEncoding, ComponentType, RedBits, GreenBits, BlueBits, etc. are all replaced by MESA_FORMAT_x queries.

* | mesa: Add support for ARB_depth_clamp.Eric Anholt2009-09-081-0/+27
|/ | | | | This currently doesn't include fixing up the cliptests in the assembly paths to support ARB_depth_clamp, so enabling depth_clamp forces the C path.
* mesa: pass 'mask', not NULL to renderbuffer->Put functionsBrian Paul2008-10-071-10/+10
| | | | Fixes bug 17800.
* mesa: prefix a bunch of #include lines with "main/".Brian Paul2008-09-181-5/+5
| | | | | This is another step toward removing a whole bunch of -I flags from the cc commands. Still need to address driver code...
* Remove the !rb->Data check that was added a few months ago.Brian2007-04-211-1/+1

* Replace MESA_FORMAT_DEPTH_COMPONENT_FLOAT32 with 32-bit integer format.Brian Paul2006-04-061-2/+81
| | | | | | | This allows render to depth texture (we don't support floating pt. Z buffers). Rename MESA_FORMAT_DEPTH_COMPONENT16/32 as MESA_FORMAT_Z16/32. Software fallback for glCopyTexImage now uses integer temporary image instead of float, eliminates a lot of float/int conversions.

* Header file clean-up:Brian Paul2002-10-241-2/+2
| | | | | | | | 1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-071-9/+11
| | | | | | | data are broken out into a new struct span_arrays which is allocated per-context (to avoid huge stack allocations - a problem on Windows). This lets us use span.redStep instead of span->redStep (for example) to hopefully get slightly better performance in the triangle functions.

| | | | | | | memory. These can be overridden by applications which need to manage this memory specially. Contributed by Gerk Huisma. Also, new code for 8-bit -> 16-bit/channel texture image storage which fills in the least-significant bits properly.
* Lots of changes related to framebuffer/window buffer resizing. Basically,Brian Paul2002-03-161-20/+21
| | | | | | | instead of passing a GLcontext* to ResizeBuffers(), pass a GLframebuffer*. The idea is that a window can be resized without it being bound to a rendering context. This makes for a nice clean-up in the XFree86 server-side GLX code. Renamed ctx->Driver.ResizeBuffersMESA() to ctx->Driver.ResizeBuffers().
