Jonathan Cameron | 10ba8ea | 2010-09-21 14:41:08 +0100 | [diff] [blame] | 713 | Description of the scan element data storage within the buffer |
Jonathan Cameron | f386caa | 2010-11-22 23:31:16 +0000 | [diff] [blame] | 714 | and hence the form in which it is read from user-space. |
Jonathan Cameron | 15739cd | 2011-09-21 11:15:51 +0100 | [diff] [blame] | 715 | Form is [be|le]:[s|u]bits/storagebits[>>shift]. |
| 716 | be or le specifies big or little endian. s or u specifies if |
Jonathan Cameron | f386caa | 2010-11-22 23:31:16 +0000 | [diff] [blame] | 717 | signed (2's complement) or unsigned. bits is the number of bits |
| 718 | of data and storagebits is the space (after padding) that it |
| 719 | occupies in the buffer. shift if specified, is the shift that |
| 720 | needs to be applied prior to masking out unused bits. Some |
| 721 | devices put their data in the middle of the transferred elements |
| 722 | with additional information on both sides. Note that some |
| 723 | devices will have additional information in the unused bits |
| 724 | so to get a clean value, the bits value must be used to mask |
| 725 | the buffer output value appropriately. The storagebits value |
| 726 | also specifies the data alignment. So s48/64>>2 will be a |
| 727 | signed 48 bit integer stored in a 64 bit location aligned to |
Peter Meerwald | 8b417d7 | 2012-06-12 15:31:27 +0200 | [diff] [blame] | 728 | a 64 bit boundary. To obtain the clean value, shift right 2 |
Jonathan Cameron | f386caa | 2010-11-22 23:31:16 +0000 | [diff] [blame] | 729 | and apply a mask to zero the top 16 bits of the result. |
