From ef456f858919ef7f40217ad8a5ed4e1e27c7ae6f Mon Sep 17 00:00:00 2001 From: Jeff Kirsher Date: Thu, 3 Nov 2011 11:40:28 +0000 Subject: [PATCH] e1000e: Convert printks to pr_ Based on the original patch from Joe Perches. Use the current logging styles. pr_ conversions are now prefixed with "e1000e:" Correct a couple of defects where the trailing NTU may have been printed on a separate line because of an interleaving hex_dump. Remove unnecessary uses of KERN_CONT and use single pr_info()s to avoid any possible output interleaving from other modules. Coalesce formats as appropriate. Remove an extra space from a broken across lines coalescing of "Link Status " and " Change". -v2 Remove changes to Copyright string CC: Joe Perches Signed-off-by: Jeff Kirsher Tested-by: Aaron Brown --- drivers/net/ethernet/intel/e1000e/netdev.c | 230 +++++++++------------ 1 file changed, 101 insertions(+), 129 deletions(-) diff --git a/drivers/net/ethernet/intel/e1000e/netdev.c b/drivers/net/ethernet/intel/e1000e/netdev.c index 80e69d37b3c7..05344d6c0a8b 100644 --- a/drivers/net/ethernet/intel/e1000e/netdev.c +++ b/drivers/net/ethernet/intel/e1000e/netdev.c @@ -163,16 +163,13 @@ static void e1000_regdump(struct e1000_hw *hw, struct e1000_reg_info *reginfo) regs[n] = __er32(hw, E1000_TARC(n)); break; default: - printk(KERN_INFO "%-15s %08x\n", - reginfo->name, __er32(hw, reginfo->ofs)); + pr_info("%-15s %08x\n", + reginfo->name, __er32(hw, reginfo->ofs)); return; } snprintf(rname, 16, "%s%s", reginfo->name, "[0-1]"); - printk(KERN_INFO "%-15s ", rname); - for (n = 0; n < 2; n++) - printk(KERN_CONT "%08x ", regs[n]); - printk(KERN_CONT "\n"); + pr_info("%-15s %08x %08x\n", rname, regs[0], regs[1]); } /* @@ -208,16 +205,15 @@ static void e1000e_dump(struct e1000_adapter *adapter) /* Print netdevice Info */ if (netdev) { dev_info(&adapter->pdev->dev, "Net device Info\n"); - printk(KERN_INFO "Device Name state " - "trans_start last_rx\n"); - printk(KERN_INFO "%-15s %016lX %016lX %016lX\n", - netdev->name, netdev->state, netdev->trans_start, - netdev->last_rx); + pr_info("Device Name state trans_start last_rx\n"); + pr_info("%-15s %016lX %016lX %016lX\n", + netdev->name, netdev->state, netdev->trans_start, + netdev->last_rx); } /* Print Registers */ dev_info(&adapter->pdev->dev, "Register Dump\n"); - printk(KERN_INFO " Register Name Value\n"); + pr_info(" Register Name Value\n"); for (reginfo = (struct e1000_reg_info *)e1000_reg_info_tbl; reginfo->name; reginfo++) { e1000_regdump(hw, reginfo); @@ -228,15 +224,14 @@ static void e1000e_dump(struct e1000_adapter *adapter) goto exit; dev_info(&adapter->pdev->dev, "Tx Ring Summary\n"); - printk(KERN_INFO "Queue [NTU] [NTC] [bi(ntc)->dma ]" - " leng ntw timestamp\n"); + pr_info("Queue [NTU] [NTC] [bi(ntc)->dma ] leng ntw timestamp\n"); buffer_info = &tx_ring->buffer_info[tx_ring->next_to_clean]; - printk(KERN_INFO " %5d %5X %5X %016llX %04X %3X %016llX\n", - 0, tx_ring->next_to_use, tx_ring->next_to_clean, - (unsigned long long)buffer_info->dma, - buffer_info->length, - buffer_info->next_to_watch, - (unsigned long long)buffer_info->time_stamp); + pr_info(" %5d %5X %5X %016llX %04X %3X %016llX\n", + 0, tx_ring->next_to_use, tx_ring->next_to_clean, + (unsigned long long)buffer_info->dma, + buffer_info->length, + buffer_info->next_to_watch, + (unsigned long long)buffer_info->time_stamp); /* Print Tx Ring */ if (!netif_msg_tx_done(adapter)) @@ -271,37 +266,32 @@ static void e1000e_dump(struct e1000_adapter *adapter) * +----------------------------------------------------------------+ * 63 48 47 40 39 36 35 32 31 24 23 20 19 0 */ - printk(KERN_INFO "Tl[desc] [address 63:0 ] [SpeCssSCmCsLen]" - " [bi->dma ] leng ntw timestamp bi->skb " - "<-- Legacy format\n"); - printk(KERN_INFO "Tc[desc] [Ce CoCsIpceCoS] [MssHlRSCm0Plen]" - " [bi->dma ] leng ntw timestamp bi->skb " - "<-- Ext Context format\n"); - printk(KERN_INFO "Td[desc] [address 63:0 ] [VlaPoRSCm1Dlen]" - " [bi->dma ] leng ntw timestamp bi->skb " - "<-- Ext Data format\n"); + pr_info("Tl[desc] [address 63:0 ] [SpeCssSCmCsLen] [bi->dma ] leng ntw timestamp bi->skb <-- Legacy format\n"); + pr_info("Tc[desc] [Ce CoCsIpceCoS] [MssHlRSCm0Plen] [bi->dma ] leng ntw timestamp bi->skb <-- Ext Context format\n"); + pr_info("Td[desc] [address 63:0 ] [VlaPoRSCm1Dlen] [bi->dma ] leng ntw timestamp bi->skb <-- Ext Data format\n"); for (i = 0; tx_ring->desc && (i < tx_ring->count); i++) { + const char *next_desc; tx_desc = E1000_TX_DESC(*tx_ring, i); buffer_info = &tx_ring->buffer_info[i]; u0 = (struct my_u0 *)tx_desc; - printk(KERN_INFO "T%c[0x%03X] %016llX %016llX %016llX " - "%04X %3X %016llX %p", - (!(le64_to_cpu(u0->b) & (1 << 29)) ?
