SNORM needs a bit of work in the state tracker in order for mipmap
generation to work I believe.
I'm also not sure that having unorm fetches for an snorm format is
sane.

I'd like to share this file with gallium u_format stuff.

This function can be done in the include file also.

With signed types we weren't hitting this test however the comment
stating this doesn't happen often doesn't apply when using signed
types since an all 0 block is quite common which isn't abs min or max.
this fixes the limits correctly again also.

if the values are all in the last dword, the high bits can be 0,
This fixes a valgrind warning I saw when playing with mipmaps.

My previous fix to the byte max was incorrect.

With proper fallback formats.

Drivers can call this function as needed. It tells the VBO module to
always unmap the current glBegin/glEnd VBO when we flush. Otherwise
it's possible to be in a flushed state but still have the VBO mapped.

This gets it building again here; I'll leave it up to the SCons
maintainers to make further improvements.
|
|
SCons has built-in support for .ll and .yy, but not .lpp and .ypp. Since
there's no real benefit to using the old names, change them.

this allows swrast to pass mipmap generation for these formats.

The max value was wrong and this showed up in the piglit tests.

this fixes some rendering in the fbo-generatemipmap-formats test on
my rv610.

No one ever cared. libdrm does dynamic resizing of its reloc-table,
anyway.

Nexuiz was hitting a software fallback.

With relaxed relocation checking in the kernel, we can specify a
negative delta (i.e. pointing outside of the target bo) in order to fake
a range in a large buffer. We only then need to upload the elements used
and adjust the buffer offset such that they correspond with the indices
used in the DrawArrays.

This breaks nexuiz for unknown reason; disable until a true fix can be

... and take advantage of start_vertex_bias to trim to [min_index,
max_index] where possible (i.e. when we need to upload all arrays).

When doing copy swapbuffers using drm, throttle on outstanding copy operations.
Introduces a new environment variable, EGL_THROTTLE_FENCES that the
user can use to indicate the desired number of outstanding swapbuffers, or
disable throttling using EGL_THROTTLE_FENCES=0.
This can and perhaps should be extended to the pageflip case as well, since
with some hardware pageflips can be pipelined. In case the pageflip syncs, the
throttle operation will be a no-op anyway.

Use the pageflip ioctl when available.
Otherwise, or when the backbuffer contents need to be preserved,
fall back to a copy operation.

The copy swap can be used when we need to preserve the contents of
the back buffer or when there is no way to do native page-flipping.

This makes it usable also for native helpers.
Also add inline functions to access the context and to
uninit the native display structure.
