3 TODO: some convenience methods maybe?
4 TODO: async compile/link
5 TODO: async $ctx->build_program
6
7 - do not try to include cl_d3d9.h - it seems to have been removed
8 from the repository, and not reliably available.

10 1.0 Sat May 5 18:43:54 CEST 2012
11 - OpenCL 1.2 is now effectively feature complete (but hardly tested).
12 - mapping a 1d image with default height now works.
13 - implement these 1.2 functions:
14 $device->sub_devices,
15 $ctx->program_with_built_in_kernels,
16 $ctx->link_program,
17 $program->compile,
18 $kernel->arg_info (and all 5 accessor methods),
19 $queue->migrate_mem_objects.
20 - implement OpenCL::context.
21 - implement $memory->destructor_callback.
22 - new methods: $mappedimage->get_row/set_row/width/height/depth/element_size.
23 - remove $kernel->set_image[23]d.
24 - add most enum and bitfield symbols to the manpage, for quick reference.
25 - default all constants to -1, instead of having them missing.
26 - try hard to get d3d definitions, when/if possible.
27 - add numerical limits and floating point constants from cl_platform.h.
28 - unify C types for accessors, for further code size decrease.
29
30 0.99 Fri May 4 01:31:15 CEST 2012
31 - OpenCL 1.1 is now effectively feature complete.
32 - work around a bug in the nvidia implementation, where build fails with
33 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
34 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
35 crashes (and OpenCL probably allows this behaviour).
36 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
37 - setf properly can now properly set local arguments ('z').
38 - using undef to pass null memory buffers now works in set_xxx.
39 - release_gl_texture was missing.
40 - fix/improve/balance gl sharing example.
41 - added non-opengl sharing opengl example.
42 - fixed some documentation links.
43 - fixed a bug where enqueue operations with optional parameters at the
44 end not specified would crash.
45 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
46 abstraction.
47 - both context_from_type methods now properly pass the notify callback.
48 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
49 - implement clCreateProgramWithBinary.
50 - speed up object constructions by not looking up stashes.
51 - use libebc for fine-tuning.
52 - reduce codesize considerably by disabling inlining on some functions.
53 - speed up many method calls on objects with no subclasses.
54
55 0.98 Sat Apr 28 15:31:46 CEST 2012
56 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
57 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
58 $queue->xxx, the enqueue_ prefix has been deprecated.
59 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
60 been deprecated.
61 - new $kernel->setf function to set kernel arguments in one go.
62 - (optional, automatic) anyevent integration.
63 - implement an event queue, use Async::Interrupt for communication.
64 - implement context notification callbacks (untested).
65 - provide a default context notification function that prints to stderr.
66 - implement event callback notifications.
67 - implement build program notifications.
68 - implement an asynchronous program build function.
69 - $ctx->build_program now distinguishes between wrong build invocations
70 and build failures.
71
72 0.97 Tue Apr 24 16:56:21 CEST 2012
73 - created $ctx->build_program utility function.
74 - enqueue_acquire/release_gl_objects did not return an event object.
75 - OpenCL::errno did not return the correct value.
76 - allow undef values in event wait lists, for convenience.
77 - implement $program->kernels_in_program.
78 - add opencl 1.2 constants.
79 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
80 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
81 - port image2d and image3d to the opencl 1.2 API.
82 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
83 if the user requests something that 1.1 cannot do when compiled
84 against 1.1. This slightly changes the API for enqueue_barrier,
85 which now checks the context it is called in.
86 - add ->format accessor for CL_IMAGHE_FORMAT.
87 - $object->id function to access internal object id.
88
89 0.96 Fri Apr 20 22:23:58 CEST 2012
90 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
91 - new $kernel->set_local function, to size local buffer arguments.
92 - use finish, not flush, in examples.
93
94 0.95 Thu Apr 19 21:25:32 CEST 2012
95 - add lengthy opengl sharing example.
96 - support property lists in CreateContext* calls.
97 - support some opengl sharing extensions
98 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
99 - support some cl_khr_gl_sharing extensions.
100 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
101 - auto-generate error codes (and include gl+d3d extensions).
102
103 0.92 Mon Apr 16 08:39:21 CEST 2012
104 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
105 when value deosn't matter).
106 - minor documentation fix (patch by Maik Hentsche).
107
108 0.91 Sun Dec 11 00:05:02 CET 2011
109 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
110 for a subbuffer is a buffer without sub_buffer methods!
111 - support apple using a different location for opencl headers - untested.
112 - be more strict when passing event lists.
113
114 0.59 Tue Nov 22 11:44:32 CET 2011
115 - provide $program->binaries method.
116 - provide $queue->enqueue_read_buffer_rect method.
117 - provide $queue->enqueue_write_buffer_rect method.
118 - coalesce like-typed accessor methods into the same xs function and
119 multiple ALIASes - this reduces the OpenCL codesize from 162kb to
120 132kb on my system.
121 - minor doc improvements.
122
123 0.55 Sun Nov 20 11:19:25 CET 2011
124 - semi-automatically generate query methods for almost all clGet*Info names.
125 - provide cl_ext.h constants.
126 - provide OpenCL::Image->image_info method.
127 - provide OpenCL::Event->profiling_info method.
128 - provide OpenCL::Kernel->work_group_info method.
129
130 0.15 Thu Nov 17 07:22:11 CET 2011
131 - include slice_pitch in enqueue_write_image (can be 0).
132 - check length in enqueue_write_image.
133 - properly calculate size in enqueue_read_image.
134 - likewise, include row_pitch and slice_pitch in image2d and image3d,
135 which must be nonzero right now, too, sorry.
136 - allow undef or missing data scalar for image2d and image3d.
137 - fix enqueue_copy_image prototype.
138 - fix formatting.
139
140 0.14 Thu Nov 17 04:04:23 CET 2011
141 - major incompatibilities due to API cleanup, the API should now be
142 mostly stable, if incomplete.
143 - fix prerequisites.
144 - replaced all _simple functions by "full" implementations, with some
145 parameters marked for future expansion - that means their API
146 should be stable from now on:
147 OpenCL::context_from_type_simple => OpenCL::context_from_type
148 $platform->context_from_type_simple => $platform->context_from_type
149 $dev->context_simple => $platform->context
150 $ctx->command_queue_simple became => $ctx->queue
151 - add OpenCL::context function.
152 - officially require C99.
153 - errno value is unspecified after a successful call.
154
155 0.03 Wed Nov 16 01:44:26 CET 2011
156 - add some reference documentation for all functions.
157 - add user event support.
158 - implement event wait lists.
159
160 0.02 Tue Nov 15 22:15:47 CET 2011
161 - first opencl kernel executed, some example code.
162
163 0.01 Tue Nov 15 05:59:00 CET 2011
164 - cloned from Convert::Scalar.
165
