Subject: [PATCH 3/5] dmidecode: Use the most appropriate unit for cache size
|
|
|
e0d5ce |
|
|
|
e0d5ce |
As newer CPUs have larger and larger cache, using kB to represent the
|
|
|
e0d5ce |
cache size is getting less convenient. Reuse the same function we have
|
|
|
e0d5ce |
for system memory size so that large units will be used as
|
|
|
e0d5ce |
appropriate. For example, a cache size reported as "20 MB" looks nicer
|
|
|
e0d5ce |
than as "20480 kB".
