From dd676ddc54f8d210f9c62a0f6a259dd4482c9b1b Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Thu, 20 Jan 2011 02:09:24 +0000 Subject: [PATCH] For Cx, each ChipSel need to be sent MR command. After this patch, tilapia can run in higher memory frequency. To test the high frequency, dont forget to change the freq limit in mcti_d.c: static void mctGet_MaxLoadFreq(struct DCTStatStruc *pDCTstat) { pDCTstat->PresetmaxFreq = 800; } Signed-off-by: Zheng Bao Acked-by: Stefan Reinauer git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6276 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/northbridge/amd/amdmct/mct_ddr3/mctsdi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/northbridge/amd/amdmct/mct_ddr3/mctsdi.c b/src/northbridge/amd/amdmct/mct_ddr3/mctsdi.c index 3318896fe..23605715b 100644 --- a/src/northbridge/amd/amdmct/mct_ddr3/mctsdi.c +++ b/src/northbridge/amd/amdmct/mct_ddr3/mctsdi.c @@ -306,7 +306,7 @@ void mct_DramInit_Sw_D(struct MCTStatStruc *pMCTstat, if (!(pDCTstat->Status & (1 << SB_Registered))) break; /* For UDIMM, only send MR commands once per channel */ } - if (pDCTstat->LogicalCPUID & (AMD_DR_Cx/* | AMD_RB_C0 */)) /* We dont support RB_C0 now. need to be added and tested. */ + if (pDCTstat->LogicalCPUID & (AMD_DR_Bx/* | AMD_RB_C0 */)) /* TODO: We dont support RB_C0 now. need to be added and tested. */ if (!(pDCTstat->Status & (1 << SB_Registered))) MrsChipSel ++; } -- 2.25.1
