+ * drm_coredump_printer - construct a &drm_printer that can output to a buffer
+ * from the read function for devcoredump
+ * @iter: A pointer to a struct drm_print_iterator for the read instance
+ *
+ * This wrapper extends drm_printf() to work with a dev_coredumpm() callback
+ * function. The passed in drm_print_iterator struct contains the buffer
+ * pointer, size and offset as passed in from devcoredump.
+ *
+ * For example::
+ *
+ * void coredump_read(char *buffer, loff_t offset, size_t count,
+ * void *data, size_t datalen)
+ * {
+ * struct drm_print_iterator iter;
+ * struct drm_printer p;
+ *
+ * iter.data = buffer;
+ * iter.start = offset;
+ * iter.remain = count;
+ *
+ * p = drm_coredump_printer(&iter);
+ *
+ * drm_printf(p, "foo=%d\n", foo);
+ * }
+ *
+ * void makecoredump(...)
+ * {
+ * ...
+ * dev_coredumpm(dev, THIS_MODULE, data, 0, GFP_KERNEL,
+ * coredump_read, ...)
+ * }
+ *
+ * The above example has a time complexity of O(N^2), where N is the size of the
+ * devcoredump. This is acceptable for small devcoredumps but scales poorly for
+ * larger ones.
+ *
+ * Another use case for drm_coredump_printer is to capture the devcoredump into
+ * a saved buffer before the dev_coredump() callback. This involves two passes:
+ * one to determine the size of the devcoredump and another to print it to a
+ * buffer. Then, in dev_coredump(), copy from the saved buffer into the
+ * devcoredump read buffer.
+ *
+ * For example::
+ *
+ * char *devcoredump_saved_buffer;
+ *
+ * ssize_t __coredump_print(char *buffer, ssize_t count, ...)
+ * {
+ * struct drm_print_iterator iter;
+ * struct drm_printer p;
+ *
+ * iter.data = buffer;
+ * iter.start = 0;
+ * iter.remain = count;
+ *
+ * p = drm_coredump_printer(&iter);
+ *
+ * drm_printf(p, "foo=%d\n", foo);
+ * ...
+ * return count - iter.remain;
+ * }
+ *
+ * void coredump_print(...)
+ * {
+ * ssize_t count;
+ *
+ * count = __coredump_print(NULL, INT_MAX, ...);
+ * devcoredump_saved_buffer = kvmalloc(count, GFP_KERNEL);
+ * __coredump_print(devcoredump_saved_buffer, count, ...);
+ * }
+ *
+ * void coredump_read(char *buffer, loff_t offset, size_t count,
+ * void *data, size_t datalen)
+ * {
+ * ...
+ * memcpy(buffer, devcoredump_saved_buffer + offset, count);
+ * ...
+ * }
+ *
+ * The above example has a time complexity of O(N*2), where N is the size of the
+ * devcoredump. This scales better than the previous example for larger
+ * devcoredumps.
