10 | help | ||
11 | This option configures this kernel to be linked at a different | ||
12 | address and use the 2nd uart for output. This allows a kernel built | ||
13 | with this option to be run at the same time as one built without this | ||
14 | option. | ||

17 | bool "Enable hardware fixups of unaligned loads and stores" | ||

19 | default "y" | ||
20 | help | ||
21 | Configure the Octeon hardware to automatically fix unaligned loads | ||
22 | and stores. Normally unaligned accesses are fixed using a kernel | ||
23 | exception handler. This option enables the hardware automatic fixups, | ||
24 | which requires only an extra 3 cycles. Disable this option if you | ||
25 | are running code that relies on address exceptions on unaligned | ||
26 | accesses. | ||

33 | help | ||
34 | CVMSEG LM is a segment that accesses portions of the dcache as a | ||
35 | local memory; the larger CVMSEG is, the smaller the cache is. | ||
36 | This selects the size of CVMSEG LM, which is in cache blocks. The | ||
37 | legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is | ||
38 | between zero and 6192 bytes). | ||
