19TODO: map_buffer -a autocalculate size
20TODO: map_image - autocalculate size
21 - work around a bug in the nvidia implementation, where build fails with
22 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
23 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
24 crashes (and OpenCL probably allows this behaviour).
25 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
26 - setf properly can now properly set local arguments ('z').
27 - using undef to pass null memory buffers now works in set_xxx.
28 - release_gl_texture was missing.
29 - fix/improve/balance gl sharing example.
30 - added non-opengl sharing opengl example.
31 - fixed some documentation links.
32 - fixed a bug where enqueue operations with optional parameters at the
33 end not specified would crash.
34 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
35 abstraction.
36 - speed up object constructions by not looking up stashes.
37
380.98 Sat Apr 28 15:31:46 CEST 2012
39 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
40 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
41 $queue->xxx, the enqueue_ prefix has been deprecated.
42 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
43 been deprecated.
44 - new $kernel->setf function to set kernel arguments in one go.
45 - (optional, automatic) anyevent integration.
46 - implement an event queue, use Async::Interrupt for communication.
47 - implement context notification callbacks (untested).
48 - provide a default context notification function that prints to stderr.
49 - implement event callback notifications.
50 - implement build program notifications.
51 - implement an asynchronous program build function.
52 - $ctx->build_program now distinguishes between wrong build invocations
53 and build failures.
54
550.97 Tue Apr 24 16:56:21 CEST 2012
56 - created $ctx->build_program utility function.
57 - enqueue_acquire/release_gl_objects did not return an event object.
58 - OpenCL::errno did not return the correct value.
59 - allow undef values in event wait lists, for convenience.
60 - implement $program->kernels_in_program.
61 - add opencl 1.2 constants.
62 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
63 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
64 - port image2d and image3d to the opencl 1.2 API.
65 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
66 if the user requests something that 1.1 cannot do when compiled
67 against 1.1. This slightly changes the API for enqueue_barrier,
68 which now checks the context it is called in.
69 - add ->format accessor for CL_IMAGHE_FORMAT.
70 - $object->id function to access internal object id.
71
720.96 Fri Apr 20 22:23:58 CEST 2012
73 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
74 - new $kernel->set_local function, to size local buffer arguments.
75 - use finish, not flush, in examples.
76
770.95 Thu Apr 19 21:25:32 CEST 2012
78 - add lengthy opengl sharing example.
79 - support property lists in CreateContext* calls.
80 - support some opengl sharing extensions
81 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
82 - support some cl_khr_gl_sharing extensions.
83 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
84 - auto-generate error codes (and include gl+d3d extensions).
85
860.92 Mon Apr 16 08:39:21 CEST 2012
87 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
88 when value deosn't matter).
89 - minor documentation fix (patch by Maik Hentsche).
90
910.91 Sun Dec 11 00:05:02 CET 2011
92 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
93 for a subbuffer is a buffer without sub_buffer methods!
94 - support apple using a different location for opencl headers - untested.
95 - be more strict when passing event lists.
96
970.59 Tue Nov 22 11:44:32 CET 2011
98 - provide $program->binaries method.
99 - provide $queue->enqueue_read_buffer_rect method.
100 - provide $queue->enqueue_write_buffer_rect method.
101 - coalesce like-typed accessor methods into the same xs function and
102 multiple ALIASes - this reduces the OpenCL codesize from 162kb to
103 132kb on my system.
104 - minor doc improvements.
105
1060.55 Sun Nov 20 11:19:25 CET 2011
107 - semi-automatically generate query methods for almost all clGet*Info names.
108 - provide cl_ext.h constants.
109 - provide OpenCL::Image->image_info method.
110 - provide OpenCL::Event->profiling_info method.
111 - provide OpenCL::Kernel->work_group_info method.
112
1130.15 Thu Nov 17 07:22:11 CET 2011
114 - include slice_pitch in enqueue_write_image (can be 0).
115 - check length in enqueue_write_image.
116 - properly calculate size in enqueue_read_image.
117 - likewise, include row_pitch and slice_pitch in image2d and image3d,
118 which must be nonzero right now, too, sorry.
119 - allow undef or missing data scalar for image2d and image3d.
120 - fix enqueue_copy_image prototype.
121 - fix formatting.
122
1230.14 Thu Nov 17 04:04:23 CET 2011
124 - major incompatibilities due to API cleanup, the API should now be
125 mostly stable, if incomplete.
126 - fix prerequisites.
127 - replaced all _simple functions by "full" implementations, with some
128 parameters marked for future expansion - that means their API
129 should be stable from now on:
130 OpenCL::context_from_type_simple => OpenCL::context_from_type
131 $platform->context_from_type_simple => $platform->context_from_type
132 $dev->context_simple => $platform->context
133 $ctx->command_queue_simple became => $ctx->queue
134 - add OpenCL::context function.
135 - officially require C99.
136 - errno value is unspecified after a successful call.
137
1380.03 Wed Nov 16 01:44:26 CET 2011
4 - add some reference documentation for all functions. 139 - add some reference documentation for all functions.
5 - add user event support. 140 - add user event support.
6 - implement event wait lists. 141 - implement event wait lists.
