3 TODO: some convenience methods maybe?
4 TODO: async compile/link
5 TODO: async $ctx->build_program
6
7 - (xthread) work around compile time bugs in ptw32.
8 - allow users to influence DEFINE and LIBS values.
9 - example context selection wasn't very robust in the presence
10 of multiple platforms.
11 - fix compilation on win32 (patch by Karel Miko).
12
13 1.01 Mon May 7 03:00:53 CEST 2012
14 - missing symbols are again exported with a 0 default value.
15 - do not try to use cl_d3d9.h - the d3d9 extension has been abondoned by khronos.
16
17 1.0 Sat May 5 18:43:54 CEST 2012
18 - OpenCL 1.2 is now effectively feature complete (but hardly tested).
19 - mapping a 1d image with default height now works.
20 - implement these 1.2 functions:
21 $device->sub_devices,
22 $ctx->program_with_built_in_kernels,
23 $ctx->link_program,
24 $program->compile,
25 $kernel->arg_info (and all 5 accessor methods),
26 $queue->migrate_mem_objects.
27 - implement OpenCL::context.
28 - implement $memory->destructor_callback.
29 - new methods: $mappedimage->get_row/set_row/width/height/depth/element_size.
30 - remove $kernel->set_image[23]d.
31 - add most enum and bitfield symbols to the manpage, for quick reference.
32 - default all constants to -1, instead of having them missing.
33 - try hard to get d3d definitions, when/if possible.
34 - add numerical limits and floating point constants from cl_platform.h.
35 - unify C types for accessors, for further code size decrease.
36
37 0.99 Fri May 4 01:31:15 CEST 2012
38 - OpenCL 1.1 is now effectively feature complete.
39 - work around a bug in the nvidia implementation, where build fails with
40 INVALID_BINARY if the compiler runs succesfully but ptxas fails.
41 - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
42 crashes (and OpenCL probably allows this behaviour).
43 - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
44 - setf properly can now properly set local arguments ('z').
45 - using undef to pass null memory buffers now works in set_xxx.
46 - release_gl_texture was missing.
47 - fix/improve/balance gl sharing example.
48 - added non-opengl sharing opengl example.
49 - fixed some documentation links.
50 - fixed a bug where enqueue operations with optional parameters at the
51 end not specified would crash.
52 - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
53 abstraction.
54 - both context_from_type methods now properly pass the notify callback.
55 - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
56 - implement clCreateProgramWithBinary.
57 - speed up object constructions by not looking up stashes.
58 - use libebc for fine-tuning.
59 - reduce codesize considerably by disabling inlining on some functions.
60 - speed up many method calls on objects with no subclasses.
61
62 0.98 Sat Apr 28 15:31:46 CEST 2012
63 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
64 - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
65 $queue->xxx, the enqueue_ prefix has been deprecated.
66 - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
67 been deprecated.
68 - new $kernel->setf function to set kernel arguments in one go.
69 - (optional, automatic) anyevent integration.
70 - implement an event queue, use Async::Interrupt for communication.
71 - implement context notification callbacks (untested).
72 - provide a default context notification function that prints to stderr.
73 - implement event callback notifications.
74 - implement build program notifications.
75 - implement an asynchronous program build function.
76 - $ctx->build_program now distinguishes between wrong build invocations
77 and build failures.
78
79 0.97 Tue Apr 24 16:56:21 CEST 2012
80 - created $ctx->build_program utility function.
81 - enqueue_acquire/release_gl_objects did not return an event object.
82 - OpenCL::errno did not return the correct value.
83 - allow undef values in event wait lists, for convenience.
84 - implement $program->kernels_in_program.
85 - add opencl 1.2 constants.
86 - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
87 $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
88 - port image2d and image3d to the opencl 1.2 API.
89 - port enqueue_marker/barrier to the opencl 1.2 API, and croak
90 if the user requests something that 1.1 cannot do when compiled
91 against 1.1. This slightly changes the API for enqueue_barrier,
92 which now checks the context it is called in.
93 - add ->format accessor for CL_IMAGHE_FORMAT.
94 - $object->id function to access internal object id.
95
96 0.96 Fri Apr 20 22:23:58 CEST 2012
97 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh.
98 - new $kernel->set_local function, to size local buffer arguments.
99 - use finish, not flush, in examples.
100
101 0.95 Thu Apr 19 21:25:32 CEST 2012
102 - add lengthy opengl sharing example.
103 - support property lists in CreateContext* calls.
104 - support some opengl sharing extensions
105 (gl_buffer, gl_texture[23]d, gl_renderbuffer).
106 - support some cl_khr_gl_sharing extensions.
107 - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
108 - auto-generate error codes (and include gl+d3d extensions).
109
110 0.92 Mon Apr 16 08:39:21 CEST 2012
111 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
112 when value deosn't matter).
113 - minor documentation fix (patch by Maik Hentsche).
114
115 0.91 Sun Dec 11 00:05:02 CET 2011
116 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj
117 for a subbuffer is a buffer without sub_buffer methods!
118 - support apple using a different location for opencl headers - untested.
119 - be more strict when passing event lists.
120
121 0.59 Tue Nov 22 11:44:32 CET 2011
122 - provide $program->binaries method.
123 - provide $queue->enqueue_read_buffer_rect method.
124 - provide $queue->enqueue_write_buffer_rect method.
125 - coalesce like-typed accessor methods into the same xs function and
126 multiple ALIASes - this reduces the OpenCL codesize from 162kb to
127 132kb on my system.
128 - minor doc improvements.
129
130 0.55 Sun Nov 20 11:19:25 CET 2011
131 - semi-automatically generate query methods for almost all clGet*Info names.
132 - provide cl_ext.h constants.
133 - provide OpenCL::Image->image_info method.
134 - provide OpenCL::Event->profiling_info method.
135 - provide OpenCL::Kernel->work_group_info method.
136
137 0.15 Thu Nov 17 07:22:11 CET 2011
138 - include slice_pitch in enqueue_write_image (can be 0).
139 - check length in enqueue_write_image.
140 - properly calculate size in enqueue_read_image.
141 - likewise, include row_pitch and slice_pitch in image2d and image3d,
142 which must be nonzero right now, too, sorry.
143 - allow undef or missing data scalar for image2d and image3d.
144 - fix enqueue_copy_image prototype.
145 - fix formatting.
146
147 0.14 Thu Nov 17 04:04:23 CET 2011
148 - major incompatibilities due to API cleanup, the API should now be
149 mostly stable, if incomplete.
150 - fix prerequisites.
151 - replaced all _simple functions by "full" implementations, with some
152 parameters marked for future expansion - that means their API
153 should be stable from now on:
154 OpenCL::context_from_type_simple => OpenCL::context_from_type
155 $platform->context_from_type_simple => $platform->context_from_type
156 $dev->context_simple => $platform->context
157 $ctx->command_queue_simple became => $ctx->queue
158 - add OpenCL::context function.
159 - officially require C99.
160 - errno value is unspecified after a successful call.
161
162 0.03 Wed Nov 16 01:44:26 CET 2011
163 - add some reference documentation for all functions.
164 - add user event support.
165 - implement event wait lists.
166
167 0.02 Tue Nov 15 22:15:47 CET 2011
168 - first opencl kernel executed, some example code.
169
170 0.01 Tue Nov 15 05:59:00 CET 2011
171 - cloned from Convert::Scalar.
172
