Ralf Baechle | 25f12b3 | 2010-09-16 11:40:41 +0100 | [diff] [blame] | 1933 | is presenting the available TC's of the core as processors to Linux. |
| 1934 | On currently available 34K processors this means a Linux system will |
| 1935 | see up to 5 processors. The implementation of the SMTC kernel differs |
| 1936 | significantly from VSMP and cannot efficiently coexist in the same |
| 1937 | kernel binary so the choice between VSMP and SMTC is a compile time |
| 1938 | decision. |
