Preliminary
Example for allocating 1152 MB of memory as a discrete segment:
9.6.4.1.3 Four GB Example
memory: 000c000000 @ 0000100000 (usable)
memory: 00a0000000 @ 0020000000 (usable)
memory: 0048000000 @ 00e0000000 (usable)
Leaving the lower 512 MB, the valid memory region is from 512MB to 3072MB
memory: 00a0000000 @ 0020000000 (usable)
memory: 0048000000 @ 00e0000000 (usable)
Leaving the lower 512 MB, the valid memory region is from 512MB to 3072MB
(for example, 2560 MB and 3584 MB to 4736 MB (for example, 1152MB)).
example for allocating 3712MB of memory:
example for allocating 3712MB of memory:
9.6.5 kuseg_start_hi=<hi_address>
This defines the most significant word of the start of physical memory in memory to
use for loading KUSEG0 apps. It is specified in Hex without the 0x prefix.
9.6.6 kuseg_start_lo=<lo_address>
This defines Least Significant word of the start of physical memory in memory to
use for loading KUSEG0 apps and is specified in Hex without the 0x prefix.
The KUSEG size Start must be
•
Greater than 512MB
•
Multiple of 2MB
•
Less than 4GB
9.6.7 kuseg_size_hi=<hi_size>
This defines Size of memory to be used for KUSEG apps (Most Significant word)
and is specified in Hex without the 0x prefix.
9.6.8 kuseg_size_lo=<lo_size>
This defines the size of memory to be used for KUSEG apps (least Significant word)
and is specified in Hex without the 0x prefix.
$ userapp xlr_loader kumem=128M@512M kumem=1024M@1024M
$ userapp xlr_loader kumem=2560M@512M kumem=1152M@3584M
Note:
Specifying only one of the values in the parameter pairs will result
in default value being used. The Most significant word will be
assumed 0 if not given in this case.
