+ help
+ IFX extension for reserving (splitting) cache ways among VPEs. You must
+ give kernel command line arguments vpe_icache_shared=0 or
+ vpe_dcache_shared=0 to enable splitting of icache or dcache
+ respectively. Then you can specify which cache ways should be
+ assigned to which VPE. There are total 8 cache ways, 4 each
+ for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
+ dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
+
+ For example, if you specify vpe_icache_shared=0 and icache_way2=1,
+ then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
+
+ For icache, software is required to make at least one cache way available
+ for a VPE at all times i.e., one can't assign all the icache ways to one
+ VPE.
+
+ By default, vpe_dcache_shared and vpe_icache_shared are set to 1
+ (i.e., both icache and dcache are shared among VPEs)
