Subject: [PATCH 185/217] cxl/test: Update CXL memory parameters
|
|
|
2eb93d |
|
|
|
2eb93d |
In support of testing CXL region configurations cxl_test changed the size
|
|
|
2eb93d |
of its root decoders and endpoints. Use the size of the first root decoder
|
|
|
2eb93d |
to determine if this is an updated kernel.
