311 | =head2 How to modify the previous example to not rely on GL sharing. |
|
|
312 | |
|
|
313 | For those poor souls with only a sucky CPU OpenCL implementation, you |
|
|
314 | currently have to read the image into some perl scalar, and then modify a |
|
|
315 | texture or use glDrawPixels or so). |
|
|
316 | |
|
|
317 | First, when you don't need gl sharing, you can create the context much simpler: |
|
|
318 | |
|
|
319 | $ctx = $platform->context (undef, [$dev]) |
|
|
320 | |
|
|
321 | To use a texture, you would modify the above example by creating an |
|
|
322 | OpenCL::Image manually instead of deriving it from a texture: |
|
|
323 | |
|
|
324 | my $tex = $ctx->image2d (OpenCL::MEM_WRITE_ONLY, OpenCL::RGBA, OpenCL::UNORM_INT8, $S, $S); |
|
|
325 | |
|
|
326 | And in the draw loop, intead of acquire_gl_objects/release_gl_objects, you |
|
|
327 | would read the image2d after the kernel has written it: |
|
|
328 | |
|
|
329 | $queue->read_image ($tex, 0, 0, 0, 0, $S, $S, 1, 0, 0, my $data); |
|
|
330 | |
|
|
331 | And then you would upload the pixel data to the texture (or use glDrawPixels): |
|
|
332 | |
|
|
333 | glTexSubImage2D_s GL_TEXTURE_2D, 0, 0, 0, $S, $S, GL_RGBA, GL_UNSIGNED_BYTE, $data; |
|
|
334 | |
|
|
335 | The fully modified example can be found at |
|

|
338 | =head2 Julia sets look soooo 80ies. |
|
|
339 | |
|
|
340 | Then colour them differently, e.g. using orbit traps! Replace the loop and |
|
|
341 | colour calculation from the previous examples by this: |
|
|
342 | |
|
|
343 | float2 dm = (float2)(1.f, 1.f); |
|
|
344 | |
|
|
345 | for (int i = 0; i < 25; ++i) |
|
|
346 | { |
|
|
347 | z = (float2)(z.x * z.x - z.y * z.y, 2.f * z.x * z.y) + c; |
|
|
348 | dm = fmin (dm, (float2)(fabs (dot (z, z) - 1.f), fabs (z.x - 1.f))); |
|
|
349 | } |
|
|
350 | |
|
|
351 | float3 colour = (float3)(dm.x * dm.y, dm.x * dm.y, dm.x); |
|
|
352 | |
|
|

409 | =head2 OPENCL 1.1 VS. OPENCL 1.2 |
|
|
410 | |
|
|
411 | This module supports both OpenCL version 1.1 and 1.2, although the OpenCL |
|
|
412 | 1.2 interface hasn't been tested much for lack of availability of an |
|
|
413 | actual implementation. |
|
|
414 | |
|
|
415 | Every function or method in this manual page that interfaces to a |
|
|
416 | particular OpenCL function has a link to the its C manual page. |
|
|
417 | |
|
|
418 | If the link contains a F<1.1>, then this function is an OpenCL 1.1 |
|
|
419 | function. Most but not all also exist in OpenCL 1.2, and this module |
|
|
420 | tries to emulate the missing ones for you, when told to do so at |
|
|
421 | compiletime. You can check whether a function was removed in OpenCL 1.2 by |
|
|
422 | replacing the F<1.1> component in the URL by F<1.2>. |
|
|
423 | |
|
|
424 | If the link contains a F<1.2>, then this is a OpenCL 1.2-only |
|
|
425 | function. Even if the module was compiled with OpenCL 1.2 header files |
|
|
426 | and has an 1.2 OpenCL library, calling such a function on a platform that |
|
|
427 | doesn't implement 1.2 causes undefined behaviour, usually a crash (But |
|
|
428 | this is not guaranteed). |
|
|
429 | |
|
|
430 | You can find out whether this module was compiled to prefer 1.1 |
|
|
431 | functionality by ooking at C<OpenCL::PREFER_1_1> - if it is true, then |
|
|
432 | 1.1 functions generally are implemented using 1.1 OpenCL functions. If it |
|
|
433 | is false, then 1.1 functions missing from 1.2 are emulated by calling 1.2 |
|
|
434 | fucntions. |
|
|
435 | |
|
|
436 | This is a somewhat sorry state of affairs, but the Khronos group choose to |
|
|
437 | make every release of OpenCL source and binary incompatible with previous |
|
|
438 | releases. |

1574 | =head3 MEMORY MAPPED BUFFERS |
|
|
1575 | |
|
|
1576 | OpenCL allows you to map buffers and images to host memory (read: perl |
|
|
1577 | scalars). This is done much like reading or copying a buffer, by enqueuing |
|
|
1578 | a map or unmap operation on the command queue. |
|
|
1579 | |
|
|
1580 | The map operations return an C<OpenCL::Mapped> object - see L<THE |
|
|
1581 | OpenCL::Mapped CLASS> section for details on what to do with these |
|
|
1582 | objects. |
|
|
1583 | |
|
|
1584 | The object will be unmapped automatically when the mapped object is |
|
|
1585 | destroyed (you can use a barrier to make sure the unmap has finished, |
|
|
1586 | before using the buffer in a kernel), but you can also enqueue an unmap |
|
|
1587 | operation manually. |
|
|
1588 | |

|
|
1592 | |
|
|
1593 | Maps the given buffer into host memory and returns an |
|
|
1594 | C<OpenCL::MappedBuffer> object. If C<$size> is specified as undef, then |
|
|
1595 | the map will extend to the end of the buffer. |
|
|
1596 | |
|
|
1597 | map_flags: OpenCL::MAP_READ, OpenCL::MAP_WRITE, OpenCL::MAP_WRITE_INVALIDATE_REGION. |

|
|
1600 | |
|
|
1601 | Example: map the buffer $buf fully and replace the first 4 bytes by "abcd", then unmap. |
|
|
1602 | |
|
|
1603 | { |
|
|
1604 | my $mapped = $queue->map_buffer ($buf, 1, OpenCL::MAP_WRITE); |
|
|
1605 | substr $$mapped, 0, 4, "abcd"; |
|
|
1606 | } # asynchronously unmap because $mapped is destroyed |

|
|
1609 | |
|
|
1610 | Maps the given image area into host memory and return an |
|
|
1611 | C<OpenCL::MappedImage> object. |
|
|
1612 | |
|
|
1613 | If any of C<$width>, C<$height> and/or C<$depth> are C<undef> then they |
|
|
1614 | will be replaced by the maximum possible value. |
|
|
1615 | |
|
|
1616 | L<http://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/clEnqueueMapImage.html> |
|
|
1617 | |
|
|
1618 | Example: map an image (with OpenCL::UNSIGNED_INT8 channel type) and set |
|
|
1619 | the first channel of the leftmost column to 5, then explicitly unmap |
|
|
1620 | it. You are not necessarily meant to do it this way, this example just |
|
|
1621 | shows you the accessors to use :) |
|
|
1622 | |
|
|
1623 | my $mapped = $queue->map_image ($image, 1, OpenCL::MAP_WRITE); |
|
|
1624 | |
|
|
1625 | $mapped->set ($_ * $mapped->row_pitch, pack "C", 5) |
|
|
1626 | for 0..$image->height; |
|
|
1627 | |
|
|
1628 | $mapped->unmap;. |
|
|
1629 | $mapped->wait; # only needed for out of order queues normally |
|

1631 | =item $ev = $queue->unmap ($mapped, $wait_events...) |

|
1633 | Unmaps the data from host memory. You must not call any methods that |
|
|
1634 | modify the data, or modify the data scalar directly, after calling this |
|
|
1635 | method. |
|
|
1636 | |
|
|
1637 | The mapped event object will always be passed as part of the |
|
|
1638 | $wait_events. The mapped event object will be replaced by the new event |

2250 | =head2 THE OpenCL::Mapped CLASS |
|
|
2251 | |
|
|
2252 | This class represents objects mapped into host memory. They are |
|
|
2253 | represented by a blessed string scalar. The string data is the mapped |
|
|
2254 | memory area, that is, if you read or write it, then the mapped object is |
|
|
2255 | accessed directly. |
|
|
2256 | |
|
|
2257 | You must only ever use operations that modify the string in-place - for |
|
|
2258 | example, a C<substr> that doesn't change the length, or maybe a regex that |
|
|
2259 | doesn't change the length. Any other operation might cause the data to be |
|
|
2260 | copied. |
|
|
2261 | |
|
|
2262 | When the object is destroyed it will enqueue an implicit unmap operation |
|
|
2263 | on the queue that was used to create it. |
|
|
2264 | |
|
|
2265 | Keep in mind that you I<need> to unmap (or destroy) mapped objects before |
|
|
2266 | OpenCL sees the changes, even if some implementations don't need this |
|
|
2267 | sometimes. |
|
|
2268 | |
|
|
2269 | Example, replace the first two floats in the mapped buffer by 1 and 2. |
|
|
2270 | |
|
|
2271 | my $mapped = $queue->map_buffer ($buf, ... |
|
|
2272 | $mapped->event->wait; # make sure it's there |
|
|
2273 | |
|
|
2274 | # now replace first 8 bytes by new data, which is exactly 8 bytes long |
|
|
2275 | # we blindly assume device endianness to equal host endianness |
|
|
2276 | # (and of course, we assume iee 754 single precision floats :) |
|
|
2277 | substr $$mapped, 0, 8, pack "f*", 1, 2; |
|
|
2278 | |
|
|
2279 | =over 4 |
|
|
2280 | |
|
|
2281 | =item $ev = $mapped->unmap ($wait_events...) |
|
|
2282 | |
|
|
2283 | Unmaps the mapped memory object, using the queue originally used to create |
|
|
2284 | it, quite similarly to C<< $queue->unmap ($mapped, ...) >>. |
|
|
2285 | |
|
|
2286 | =item $bool = $mapped->mapped |
|
|
2287 | |
|
|
2288 | Returns whether the object is still mapped - true before an C<unmap> is |
|
|
2289 | enqueued, false afterwards. |
|
|
2290 | |
|
|
2291 | =item $ev = $mapped->event |
|
|
2292 | |
|
|
2293 | Return the event object associated with the mapped object. Initially, this |
|
|
2294 | will be the event object created when mapping the object, and after an |
|
|
2295 | unmap, this will be the event object that the unmap operation created. |
|
|
2296 | |
|
|
2297 | =item $mapped->wait |
|
|
2298 | |
|
|
2299 | Same as C<< $mapped->event->wait >> - makes sure no operations on this |
|
|
2300 | mapped object are outstanding. |
|
|
2301 | |
|
|
2302 | =item $bytes = $mapped->size |
|
|
2303 | |
|
|
2304 | Returns the size of the mapped area, in bytes. Same as C<length $$mapped>. |
|
|
2305 | |
|
|
2306 | =item $ptr = $mapped->ptr |
|
|
2307 | |
|
|
2308 | Returns the raw memory address of the mapped area. |
|
|
2309 | |
|
|
2310 | =item $mapped->set ($offset, $data) |
|
|
2311 | |
|
|
2312 | Replaces the data at the given C<$offset> in the memory area by the new |
|
|
2313 | C<$data>. This method is safer than direct manipulation of C<$mapped> |
|
|
2314 | because it does bounds-checking, but also slower. |
|
|
2315 | |
|
|
2316 | =item $data = $mapped->get ($offset, $length) |
|
|
2317 | |
|
|
2318 | Returns (without copying) a scalar representing the data at the given |
|
|
2319 | C<$offset> and C<$length> in the mapped memory area. This is the same as |
|
|
2320 | the following substr, except much slower; |
|
|
2321 | |
|
|
2322 | $data = substr $$mapped, $offset, $length |
