Prev: cfq fsync patch testing results (Was: Re: [RFC PATCH] cfq-iosched: IOPS mode for group scheduling and new group_idle tunable)
Next: [PATCH 06/17] x86, memblock: Add get_free_all_memory_range()
From: Yinghai Lu on 29 Jul 2010 15:50 Also let memblock_x86_reserve_range/memblock_x86_free_range could print out name if memblock=debug is specified will also print ther name when reserve_memblock_area/free_memblock_area are called. -v2: according to Ingo, put " if (memblock_debug) " in one place Signed-off-by: Yinghai Lu <yinghai(a)kernel.org> --- arch/x86/mm/memblock.c | 20 ++++++++++++-------- 1 files changed, 12 insertions(+), 8 deletions(-) diff --git a/arch/x86/mm/memblock.c b/arch/x86/mm/memblock.c index e36a10a..37dfa23 100644 --- a/arch/x86/mm/memblock.c +++ b/arch/x86/mm/memblock.c @@ -118,10 +118,10 @@ static void __init memblock_x86_subtract_reserved(struct range *range, int az) /* Take out region array itself at first*/ memblock_free_reserved_regions(); - pr_info("Subtract (%ld early reservations)\n", memblock.reserved.cnt); + memblock_dbg("Subtract (%ld early reservations)\n", memblock.reserved.cnt); for_each_memblock(reserved, r) { - pr_info(" [%010llx-%010llx]\n", (u64)r->base, (u64)r->base + r->size - 1); + memblock_dbg(" [%010llx-%010llx]\n", (u64)r->base, (u64)r->base + r->size - 1); final_start = PFN_DOWN(r->base); final_end = PFN_UP(r->base + r->size); if (final_start >= final_end) @@ -193,16 +193,16 @@ void __init memblock_x86_to_bootmem(u64 start, u64 end) memblock_free_reserved_regions(); count = memblock.reserved.cnt; - pr_info("(%d early reservations) ==> bootmem [%010llx-%010llx]\n", count, start, end - 1); + memblock_dbg("(%d early reservations) ==> bootmem [%#010llx-%#010llx]\n", count, start, end - 1); for_each_memblock(reserved, r) { - pr_info(" [%010llx-%010llx] ", (u64)r->base, (u64)r->base + r->size - 1); + memblock_dbg(" [%#010llx-%#010llx] ", (u64)r->base, (u64)r->base + r->size - 1); final_start = max(start, r->base); final_end = min(end, r->base + r->size); if (final_start >= final_end) { - pr_cont("\n"); + memblock_dbg("\n"); continue; } - pr_cont(" ==> [%010llx-%010llx]\n", final_start, final_end - 1); + memblock_dbg(" ==> [%#010llx-%#010llx]\n", final_start, final_end - 1); reserve_bootmem_generic(final_start, final_end - final_start, BOOTMEM_DEFAULT); } @@ -280,9 +280,11 @@ void __init memblock_x86_reserve_range(u64 start, u64 end, char *name) if (start == end) return; - if (WARN_ONCE(start > end, "memblock_x86_reserve_range: wrong range [%#llx, %#llx]\n", start, end)) + if (WARN_ONCE(start > end, "memblock_x86_reserve_range: wrong range [%#llx, %#llx)\n", start, end)) return; + memblock_dbg(" memblock_x86_reserve_range: [%#010llx-%#010llx] %16s\n", start, end - 1, name); + memblock_reserve(start, end - start); } @@ -291,9 +293,11 @@ void __init memblock_x86_free_range(u64 start, u64 end) if (start == end) return; - if (WARN_ONCE(start > end, "memblock_x86_free_range: wrong range [%#llx, %#llx]\n", start, end)) + if (WARN_ONCE(start > end, "memblock_x86_free_range: wrong range [%#llx, %#llx)\n", start, end)) return; + memblock_dbg(" memblock_x86_free_range: [%#010llx-%#010llx]\n", start, end - 1); + memblock_free(start, end - start); } -- 1.6.4.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
