From 822f63fc947bf20a2651af14b3da9a5dea7a363d Mon Sep 17 00:00:00 2001 From: Bill Paul <wpaul@FreeBSD.org> Date: Sun, 10 Aug 2003 18:04:35 +0000 Subject: [PATCH] The BCM5704 ASIC has a smaller mbuf space than the 5700/1/2/3. Failure to configure this correctly yields many watchdog timeouts even on lightly loaded machines. This is a common complaint from users with Dell 1750 servers with built-in dual 5704 NICs. --- sys/dev/bge/if_bge.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/sys/dev/bge/if_bge.c b/sys/dev/bge/if_bge.c index d78177986c77..df389e47eaa6 100644 --- a/sys/dev/bge/if_bge.c +++ b/sys/dev/bge/if_bge.c @@ -1310,16 +1310,24 @@ bge_blockinit(sc) */ CSR_WRITE_4(sc, BGE_PCI_MEMWIN_BASEADDR, 0); + /* Note: the BCM5704 has a smaller mbuf space than other chips. */ + if (sc->bge_asicrev != BGE_ASICREV_BCM5705) { /* Configure mbuf memory pool */ if (sc->bge_extram) { CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_BASEADDR, BGE_EXT_SSRAM); - CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x18000); + if (sc->bge_asicrev == BGE_ASICREV_BCM5704) + CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x10000); + else + CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x18000); } else { CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_BASEADDR, BGE_BUFFPOOL_1); - CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x18000); + if (sc->bge_asicrev == BGE_ASICREV_BCM5704) + CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x10000); + else + CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x18000); } /* Configure DMA resource pool */
