Subject: [PATCH] powerpc/64s: Make boot look nice(r)
Date: Thu, 16 May 2019 12:04:37 +1000 [thread overview]
Message-ID: <20190516020437.11783-1-npiggin@gmail.com> (raw)
Radix boot looks like this:
-----------------------------------------------------
phys_mem_size = 0x200000000
dcache_bsize = 0x80
icache_bsize = 0x80
cpu_features = 0x0000c06f8f5fb1a7
possible = 0x0000fbffcf5fb1a7
always = 0x00000003800081a1
cpu_user_features = 0xdc0065c2 0xaee00000
mmu_features = 0xbc006041
firmware_features = 0x0000000010000000
hash-mmu: ppc64_pft_size = 0x0
hash-mmu: kernel vmalloc start = 0xc008000000000000
hash-mmu: kernel IO start = 0xc00a000000000000
hash-mmu: kernel vmemmap start = 0xc00c000000000000
-----------------------------------------------------
Fix:
-----------------------------------------------------
phys_mem_size = 0x200000000
dcache_bsize = 0x80
icache_bsize = 0x80
cpu_features = 0x0000c06f8f5fb1a7
possible = 0x0000fbffcf5fb1a7
always = 0x00000003800081a1
cpu_user_features = 0xdc0065c2 0xaee00000
mmu_features = 0xbc006041
firmware_features = 0x0000000010000000
vmalloc start = 0xc008000000000000
IO start = 0xc00a000000000000
vmemmap start = 0xc00c000000000000
