From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andy Shevchenko Subject: [PATCH v1 1/1] RDMA/nes: replace custom print_hex_dump() Date: Fri, 6 May 2016 20:19:42 +0300 Message-ID: <1462555182-49917-1-git-send-email-andriy.shevchenko@linux.intel.com> Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Faisal Latif , linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Roland Dreier Cc: Andy Shevchenko List-Id: linux-rdma@vger.kernel.org There is no need to duplicate a lot of code that is in the kernel library for ages. Replace duplicating code by calling to print_hex_dump() directly. Note that output is slightly changed: - hex and ascii parts have just two spaces delimeter - there is no delimeter for ascii portions - file and line removed from prefix (they were redundant anyway since previous output shows same closer enough) Signed-off-by: Andy Shevchenko --- drivers/infiniband/hw/nes/nes_utils.c | 60 ++--------------------------------- 1 file changed, 3 insertions(+), 57 deletions(-) diff --git a/drivers/infiniband/hw/nes/nes_utils.c b/drivers/infiniband/hw/nes/nes_utils.c index 6d3a169..37331e2 100644 --- a/drivers/infiniband/hw/nes/nes_utils.c +++ b/drivers/infiniband/hw/nes/nes_utils.c @@ -44,6 +44,7 @@ #include #include #include +#include #include #include @@ -903,70 +904,15 @@ void nes_clc(unsigned long parm) */ void nes_dump_mem(unsigned int dump_debug_level, void *addr, int length) { - char xlate[] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', - 'a', 'b', 'c', 'd', 'e', 'f'}; - char *ptr; - char hex_buf[80]; - char ascii_buf[20]; - int num_char; - int num_ascii; - int num_hex; - if (!(nes_debug_level & dump_debug_level)) { return; } - ptr = addr; if (length > 0x100) { nes_debug(dump_debug_level, "Length truncated from %x to %x\n", length, 0x100); length = 0x100; } - nes_debug(dump_debug_level, "Address=0x%p, length=0x%x (%d)\n", ptr, length, length); - - memset(ascii_buf, 0, 20); - memset(hex_buf, 0, 80); - - num_ascii = 0; - num_hex = 0; - for (num_char = 0; num_char < length; num_char++) { - if (num_ascii == 8) { - ascii_buf[num_ascii++] = ' '; - hex_buf[num_hex++] = '-'; - hex_buf[num_hex++] = ' '; - } - - if (*ptr < 0x20 || *ptr > 0x7e) - ascii_buf[num_ascii++] = '.'; - else - ascii_buf[num_ascii++] = *ptr; - hex_buf[num_hex++] = xlate[((*ptr & 0xf0) >> 4)]; - hex_buf[num_hex++] = xlate[*ptr & 0x0f]; - hex_buf[num_hex++] = ' '; - ptr++; - - if (num_ascii >= 17) { - /* output line and reset */ - nes_debug(dump_debug_level, " %s | %s\n", hex_buf, ascii_buf); - memset(ascii_buf, 0, 20); - memset(hex_buf, 0, 80); - num_ascii = 0; - num_hex = 0; - } - } + nes_debug(dump_debug_level, "Address=0x%p, length=0x%x (%d)\n", addr, length, length); - /* output the rest */ - if (num_ascii) { - while (num_ascii < 17) { - if (num_ascii == 8) { - hex_buf[num_hex++] = ' '; - hex_buf[num_hex++] = ' '; - } - hex_buf[num_hex++] = ' '; - hex_buf[num_hex++] = ' '; - hex_buf[num_hex++] = ' '; - num_ascii++; - } - - nes_debug(dump_debug_level, " %s | %s\n", hex_buf, ascii_buf); - } + print_hex_dump(KERN_ERR, PFX, DUMP_PREFIX_NONE, 16, 1, addr, length, true); } -- 2.8.1 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
