DRAM self refresh check in src/northbridge/i945/raminit.c
by Sven Schnelle 22 Mar '11

22 Mar '11

Hi List, one of the last remaining problems with the ThinkPad X60 port is that coreboot does a full reset on ACPI S3 wakeup. There's an explicit check that the DRAM self refresh bits in PMSTS (MCHBAR offset 0xf14) are set. For (yet) unknown reasons, those bits are not set on my Thinkpad after Wakeup, even though suspending works for several days, without the DRAM being refreshed by the Chipset, so i guess Self Refresh is working. I've commented the check out, with the following diff: Does anyone have an idea why that check fails? diff --git a/src/northbridge/intel/i945/raminit.c b/src/northbridge/intel/i945/raminit.c index 8b7ffa1..e6990f7 100644 --- a/src/northbridge/intel/i945/raminit.c +++ b/src/northbridge/intel/i945/raminit.c @@ -312,10 +312,12 @@ static void sdram_detect_errors(struct sys_info *sysinfo) } if (do_reset) { - printk(BIOS_DEBUG, "Reset required.\n"); + printk(BIOS_DEBUG, "Reset required.

[GSoC] Coreboot Spice Payload
by Leandro Dorileo 21 Mar '11

21 Mar '11

Hi Guys! I saw coreboot was accepted as mentoring organization for GSoC this year once again. I want to participate this year again as student and I came with the idea of a Coreboot Spice Payload. I wrote a small text[1] describing the idea. I would like to hear from you what you think. I have discussed with some guys already but would like to open it a bit more. [1] - http://vps.dorilex.net/~dorileo/coreboot-spice-payload.txt Thanks.... -- Leandro Dorileo

ATOM + US15
by Anish Patel 21 Mar '11

21 Mar '11

Hi All, I am still working on my ATOM unit, and have encountered a hold up. When the unit is trying to setup the memory and getting to the detect_softstrap_base() function it returns a base value of 0, because i am assume it doesn't meet any of these 4 cases. i guess in short, is there a way to find the softstrap_base from a running system? Thanks Anish

[PATCH] BUILD: add -MMD to iasl cpp call
by Sven Schnelle 20 Mar '11

Right now there are no dependency rules for compiling dsdt.asl. If ACPI code includes asl files, the dsdt isn't recompiled if any of those file is changed.
