In short what the code did before:
__DRIscreen *psp = NULL;
if (pcp)
psp = pcp->psb;
assert(psp);
if (psp->stuff)
other_stuff();
return psb->even_more(pcp);
Remove all that stupid checking which still segfaults/asserts later on and
just do what we do in driUnbindContext. Also limited testing show libGL never
call driUnbindContext or driBindContext with cPriv == NULL.
libdrm-2.4.20 and earlier include the nouveau/nouveau_class.h header. A
later version of libdrm will not ship this header. Mesa also has this
header at src/gallium/drivers.
The symbol NV34TCL_VTXFMT_TYPE_HALF is needed by nvfx_vbo.c. This symbol
is not in the libdrm copy of the header but is in the Mesa copy of the
header. This patch moves src/gallium/drivers to the beginning of the
include paths such that when building on hosts with libdrm-2.4.20 or
ealier the build uses the copy in Mesa.
we were only running the llvm paths when the input elts were linear,
now we can handle abritrary fetch elts arrays. we do this by generating
two paths - linear and fetch_elts one and just selecting the right one
at run time.
max_index must be observed to prevent crashes due to bad index data.
I've been using this patch for some time without regressions.
Some places, where we use internal vertex buffer, it is not entirely
clear what max_index should be, so passing just ~0 to avoid regressions
for now.
doc additions: shader export ARRAY_BASE for EXPORT_POS: 60 is position,
61 is misc vec(VS_OUT_MISC_VEC - used here),
62, 63 are clip distance vectors(VS_OUT_CCDIST#)
sorry for formating - there seem to be so many different styles in r600
Certain headers, such as GL/glew.h, are in both the Mesa include and the
default installed include directories. On recent distros the needed
symbols can be found in both places. On older distros the installed
headers could be lacking symbols, so for a header that exists in both
places, the local one should be found first.
The POSIX function pthread_cond_wait can have spurious wakeups when
waiting on a condition variable.
Add a 64-bit counter that is incremented whenever the barrier becomes
full. A woken thread checks the counter. If the counter has not changed
then it has been spuriously woken and goes back to sleep. If the counter
has changed then it was properly signaled and exits the barrier.
Tested on Mac OS X.
This patch was based on ideas from Luca Barbieri.
