[PATCH v2] powerpc/mm: Add a parameter to disable 1TB segs

2016-07-04 Thread Oliver O'Halloran
This patch adds the kernel command line parameter "no_tb_segs" which forces the kernel to use 256MB rather than 1TB segments. Forcing the use of 256MB segments makes it considerably easier to test code that depends on an SLB miss occurring. Suggested-by: Michael Neuling Suggested-by: Michael Elle

[PATCH] powerpc/mm: Add a parameter to disable 1TB segs

2016-07-03 Thread Oliver O'Halloran
This patch adds the kernel command line parameter "no_tb_segs" which forces the kernel to use 256MB rather than 1TB segments. Forcing the use of 256MB segments makes it considerably easier to test code that depends on an SLB miss occurring. Suggested-by: Michael Neuling Suggested-by: Michael Elle
