New patch to review for coreboot: b228080 haswell: allow for disabled hyperthreading

Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3353 -gerrit commit b2280806bcbca6b6df011da8b387be02c5c9bc79 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue May 28 14:26:29 2013 -0500 haswell: allow for disabled hyperthreading There were assumptions being made in the haswell MP and SMM code which assumed the APIC id space was 1:1 w.r.t. cpu number. When hyperthreading is disabled the APIC ids of the logical processors are all even. That means the APIC id space is sparse. Handle this situation.

Patch set updated for coreboot: 84d41ea NOTFORMERGE: VX900 early init, and EPIA M850 board
by Alexandru Gagniuc 03 Jun '13

03 Jun '13

Alexandru Gagniuc (mr.nuke.me(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/1228 -gerrit commit 84d41eaf5a6395d943f4902a93e78b2fbe5bdbae Author: Alexandru Gagniuc <mr.nuke.me(a)gmail.com> Date: Tue May 21 14:51:26 2013 -0500 NOTFORMERGE: VX900 early init, and EPIA M850 board I will split this up into pallatable chunks once the dependencies are merged. This is the patch where all VX900 development is taking place. The NOTFORMERGE modifier is here to indicate that the code ain't ready. =========================================================================== == Early initialization for VIA VX900: --------------------------------------------------------------------------- MMCONF: Works from very early ramstage. Enabling MMCONF only seems to save a few milliseconds of boot time. The plan is to change the MMCONF implementation in coreboot to allow dynamically changing the MMCONF_BASE, and then use the resource allocator to get a 256MB chunk for MMCONF. SMBUS is functional. RAMINIT: Raminit works with 1 rank, but not with several ranks. DRAM calibration when more than one DIMM is does not work well. The delay calibration strategy is to put some predefined delays for the DQ input delays, and run hardware calibration on the other three delays (DQS input, DQ/DQS output). For the future, we could change this strategy to one that uses the hardware calibration of DQ input. Unfortunately, according to my testing, the DQ input delay calibration does not work reliably. Memtest runs through the serial console. It whines about memory errors during the random test (#7), but this seems to be because it tries to use the VGA memory hole (Errors start consistently at 128MB + 768K). =========================================================================== == VX900 in ramstage: --------------------------------------------------------------------------- MP tables and IOAPIC: VX900 code enables the IOAPICs are enabled as long as they're declared in devicetree.cb. Since we rely on automatic MP table generation, if an IOAPIC is not properly declared, the code spits out an error, and continues without initializing it. LPC: Implemented LPC driver with PIC interrupt routing. VGA: Still displays garbage and/or nothing. Video BIOS depends on proprietary interrupt handlers, some of which are implemented as YABEL interrupt handlers. If run in YABEL mode, the VGA BIOS requires access to other PCI devices and direct hardware access, it seems. GRUB2 and Linux are capable of initializing the VGA post-coreboot. Linux can use the VGA normally, but hangs after a while. SATA: The controller does not support AHCI, or a compliant SATA implementation. Normally SATA is done by setting RAID mode, but then SeaBIOS will not use it to boot. The only viable option is to keep the controller in native IDE mode. SATA device detection works reliably when one drive is attached. ATA DMA mode works reliably. =========================================================================== == VIA EPIA M850 board: --------------------------------------------------------------------------- Minimal infrastructure to compile a coreboot image for this board is added. PIRQ_TABLE: Implemented, Linux can find and use irqs with "noapic acpi=off" MP_TABLE: Partially generated from devicetree.cb. Not tested. KEYBOARD WORKS!!!

This file was missing some definitions, so add them. Also turn the defines into an enum. The reason for doing this is that functions can now explicitly take an spd_memory_type as a parameter: > int do_something_with_dram(enum spd_memory_type type, ...) Which is a lot more explicit and readable than: > int do_something_with_dram(u8 type, ...) These are used in the VX900 branch.

Alexandru Gagniuc (mr.nuke.me(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3267 -gerrit commit 171796e3efce3f8042347dd4174619769edf9523 Author: Alexandru Gagniuc <mr.nuke.me(a)gmail.com> Date: Tue May 21 14:43:45 2013 -0500 dram: Add utilities for decoding DDR3 SPDs Add convenience utilities for decoding DDR3 SPDs and printing the information to the console. These have proven invaluable when writing the VX900 memory initialization. These are used in the VX900 branch Information printed has the following format: > SPD Data for DIMM 51 > Revision: 10 > Type : b > Key : 2 > Banks : 8 > Capacity: 1 Gb > Supported voltages: 1.5V > SDRAM width : 8 > Bus extension : 0 bits > Bus width : 64 > Optional features : DLL-Off_mode RZQ/7 RZQ/6 > Thermal features : ASR ext_temp_range > Thermal sensor : no > Standard SDRAM : no > Row addr bits : 13 > Column addr bits : 10 > Number of ranks : 1 > DIMM Capacity : 1024 MB > CAS latencies : 6 7 8 9 > tCKmin : 1.500 ns > tAAmin : 13.125 ns > tWRmin : 15.000 ns > tRCDmin : 13.125 ns > tRRDmin : 6.000 ns > tRPmin : 13.125 ns > tRASmin : 36.000 ns > tRCmin : 49.125 ns > tRFCmin : 110.000 ns > tWTRmin : 7.500 ns > tRTPmin : 7.500 ns > tFAWmin : 30.000 ns Change-Id: I30725a75caf74ac637db0a143344562bd9910466 Signed-off-by: Alexandru Gagniuc <mr.nuke.me(a)gmail.com> --- src/device/dram/ddr3.c | 372 +++++++++++++++++++++++++++++++++++++++++ src/include/device/dram/ddr3.h | 189 +++++++++++++++++++++ 2 files changed, 561 insertions(+) diff --git a/src/device/dram/ddr3.c b/src/device/dram/ddr3.c new file mode 100644 index 0000000..c745bd7 --- /dev/null +++ b/src/device/dram/ddr3.c @@ -0,0 +1,372 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2011-2013 Alexandru Gagniuc <mr.nuke.me(a)gmail.com> + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
