Priority: medium
Bug ID: 75543
Assignee: mesa-dev@lists.freedesktop.org
Summary: OSMesa Gallium OSMesaMakeCurrent
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: nacho...@gmail.com
Hardware: All
Status: NEW
Version: git
Component: Mesa core
Product: Mesa
Related Bug ID: 63117
Function at /Mesa-10.0.3/src/gallium/state_trackers/osmesa/osmesa.c
Is defined as:
osmesa_find_buffer(enum pipe_format color_format,
enum pipe_format ds_format,
enum pipe_format accum_format)
but should take care, also, of buffer size, other case mesa segfaults when size
changes between calls.
As a workaround I implemented it as (but probably is not the best approach):
static struct osmesa_buffer *
osmesa_find_buffer(enum pipe_format color_format,
enum pipe_format ds_format,
enum pipe_format accum_format,
GLsizei width, GLsizei height
)
{
struct osmesa_buffer *b;
/* Check if we already have a suitable buffer for the given formats */
for (b = BufferList; b; b = b->next) {
if (b->visual.color_format == color_format &&
b->visual.depth_stencil_format == ds_format &&
b->visual.accum_format == accum_format &&
b->width == width &&
b->height == height) {
return b;
}
}
return NULL;
}
