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