Revision history for Perl extension OpenCL. TODO: some convenience methods maybe? TODO: async compile/link TODO: async $ctx->build_program - (xthread) work around compile time bugs in ptw32. - allow users to influence DEFINE and LIBS values. - example context selection wasn't very robust in the presence of multiple platforms. - fix compilation on win32 (patch by Karel Miko). 1.01 Mon May 7 03:00:53 CEST 2012 - missing symbols are again exported with a 0 default value. - do not try to use cl_d3d9.h - the d3d9 extension has been abondoned by khronos. 1.0 Sat May 5 18:43:54 CEST 2012 - OpenCL 1.2 is now effectively feature complete (but hardly tested). - mapping a 1d image with default height now works. - implement these 1.2 functions: $device->sub_devices, $ctx->program_with_built_in_kernels, $ctx->link_program, $program->compile, $kernel->arg_info (and all 5 accessor methods), $queue->migrate_mem_objects. - implement OpenCL::context. - implement $memory->destructor_callback. - new methods: $mappedimage->get_row/set_row/width/height/depth/element_size. - remove $kernel->set_image[23]d. - add most enum and bitfield symbols to the manpage, for quick reference. - default all constants to -1, instead of having them missing. - try hard to get d3d definitions, when/if possible. - add numerical limits and floating point constants from cl_platform.h. - unify C types for accessors, for further code size decrease. 0.99 Fri May 4 01:31:15 CEST 2012 - OpenCL 1.1 is now effectively feature complete. - work around a bug in the nvidia implementation, where build fails with INVALID_BINARY if the compiler runs succesfully but ptxas fails. - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia crashes (and OpenCL probably allows this behaviour). - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf. - setf properly can now properly set local arguments ('z'). - using undef to pass null memory buffers now works in set_xxx. - release_gl_texture was missing. - fix/improve/balance gl sharing example. - added non-opengl sharing opengl example. - fixed some documentation links. - fixed a bug where enqueue operations with optional parameters at the end not specified would crash. - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object" abstraction. - both context_from_type methods now properly pass the notify callback. - $platform->context now properly passes CL_CONTEXT_PLATFORM again. - implement clCreateProgramWithBinary. - speed up object constructions by not looking up stashes. - use libebc for fine-tuning. - reduce codesize considerably by disabling inlining on some functions. - speed up many method calls on objects with no subclasses. 0.98 Sat Apr 28 15:31:46 CEST 2012 - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef. - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just $queue->xxx, the enqueue_ prefix has been deprecated. - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have been deprecated. - new $kernel->setf function to set kernel arguments in one go. - (optional, automatic) anyevent integration. - implement an event queue, use Async::Interrupt for communication. - implement context notification callbacks (untested). - provide a default context notification function that prints to stderr. - implement event callback notifications. - implement build program notifications. - implement an asynchronous program build function. - $ctx->build_program now distinguishes between wrong build invocations and build failures. 0.97 Tue Apr 24 16:56:21 CEST 2012 - created $ctx->build_program utility function. - enqueue_acquire/release_gl_objects did not return an event object. - OpenCL::errno did not return the correct value. - allow undef values in event wait lists, for convenience. - implement $program->kernels_in_program. - add opencl 1.2 constants. - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler, $queue->enqueue_fill_buffer/image, all untested (opencl 1.2). - port image2d and image3d to the opencl 1.2 API. - port enqueue_marker/barrier to the opencl 1.2 API, and croak if the user requests something that 1.1 cannot do when compiled against 1.1. This slightly changes the API for enqueue_barrier, which now checks the context it is called in. - add ->format accessor for CL_IMAGHE_FORMAT. - $object->id function to access internal object id. 0.96 Fri Apr 20 22:23:58 CEST 2012 - ->enqueue_write_buffer actually called enqueue_read_buffer. d'oh. - new $kernel->set_local function, to size local buffer arguments. - use finish, not flush, in examples. 0.95 Thu Apr 19 21:25:32 CEST 2012 - add lengthy opengl sharing example. - support property lists in CreateContext* calls. - support some opengl sharing extensions (gl_buffer, gl_texture[23]d, gl_renderbuffer). - support some cl_khr_gl_sharing extensions. - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h). - auto-generate error codes (and include gl+d3d extensions). 0.92 Mon Apr 16 08:39:21 CEST 2012 - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR when value deosn't matter). - minor documentation fix (patch by Maik Hentsche). 0.91 Sun Dec 11 00:05:02 CET 2011 - introduce $buffer_obj->sub_buffer_region method and a new class, OpenCL::BufferObj for a subbuffer is a buffer without sub_buffer methods! - support apple using a different location for opencl headers - untested. - be more strict when passing event lists. 0.59 Tue Nov 22 11:44:32 CET 2011 - provide $program->binaries method. - provide $queue->enqueue_read_buffer_rect method. - provide $queue->enqueue_write_buffer_rect method. - coalesce like-typed accessor methods into the same xs function and multiple ALIASes - this reduces the OpenCL codesize from 162kb to 132kb on my system. - minor doc improvements. 0.55 Sun Nov 20 11:19:25 CET 2011 - semi-automatically generate query methods for almost all clGet*Info names. - provide cl_ext.h constants. - provide OpenCL::Image->image_info method. - provide OpenCL::Event->profiling_info method. - provide OpenCL::Kernel->work_group_info method. 0.15 Thu Nov 17 07:22:11 CET 2011 - include slice_pitch in enqueue_write_image (can be 0). - check length in enqueue_write_image. - properly calculate size in enqueue_read_image. - likewise, include row_pitch and slice_pitch in image2d and image3d, which must be nonzero right now, too, sorry. - allow undef or missing data scalar for image2d and image3d. - fix enqueue_copy_image prototype. - fix formatting. 0.14 Thu Nov 17 04:04:23 CET 2011 - major incompatibilities due to API cleanup, the API should now be mostly stable, if incomplete. - fix prerequisites. - replaced all _simple functions by "full" implementations, with some parameters marked for future expansion - that means their API should be stable from now on: OpenCL::context_from_type_simple => OpenCL::context_from_type $platform->context_from_type_simple => $platform->context_from_type $dev->context_simple => $platform->context $ctx->command_queue_simple became => $ctx->queue - add OpenCL::context function. - officially require C99. - errno value is unspecified after a successful call. 0.03 Wed Nov 16 01:44:26 CET 2011 - add some reference documentation for all functions. - add user event support. - implement event wait lists. 0.02 Tue Nov 15 22:15:47 CET 2011 - first opencl kernel executed, some example code. 0.01 Tue Nov 15 05:59:00 CET 2011 - cloned from Convert::Scalar.
