DRAM training accounts for most of the romstage startup time, yet if the hardware configuration has not changed from the previous boot the previously discovered training values are still valid. Use them if the DIMM configuration has not changed since the last boot. The SPD values of all installed DIMMs are hashed and stored in the S3 resume data area of the main system Flash device. If a DIMM is changed the hash will almost certainly change as well, forcing retraining on next boot.

2015-11-11amd/amdmct/mct_ddr3: Improve SPD DIMM detect reliabilityTimothy Pearson
Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over I2C on a system with all DIMM slots populated. If even one of those reads has a single flipped bit in it (due to EMI, cross coupling with another trace, or just poor margins on some cheap DIMM) the system will hang and require a hard reset. In practice I've seen failure rates as high as 1 failed boot in 50 due to this issue, granted with cheap DIMMs, but even so retrying the read resolves the corruption issue. I2C is not designed for continuous data transmission with high reliability, and there is no hardware error checking, therefore a single retry when transferring this amount of data makes sense.

The native AMD DDR3 memory initialization code was riddled with numerous errors and was missing critical configuration code segments; this made it so that DDR3 memory did not function on most AMD boards. This patch corrects enough of the DDR3 initialization such that UDIMMs can be used on most channels of G34 Opteron boards. Further work is needed to fix the broken RDIMM code and remaining UDIMM issues.

As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2011-02-28Improving BKDG implementation of P-states,Xavi Drudis Ferran
CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. In fact I changed coreDelay before deleting the code in fidvid that called it. But there're still a couple of calls from src/northbridge/amd/amdmct/wrappers/mcti_d.c Since the comment encouraged fixing something, I parametrized it with the delay time in microseconds and paranoically tried to avoid an overflow at pathological moments.

2011-02-28Improving BKDG implementation of P-states,Xavi Drudis Ferran
CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Factor out some common expressions. Add an error message when coreboots hangs waiting for a pstate that never comes (it happened to me), and throw some paranoia at it for good mesure. If I understood BKDG fam10 CPUs never need a software initiated vid transition, because the hardware knows what to do when you just request a Pstate change if the cpu is properly configured. In fact unifying a little what PVI and SVI do was better for my board (SVI). So I drop transitionVid, which I didn't understand either (why did it have a case for PVI if it is never called for PVI ? Why did the PVI case distinguigh cpu or nb when PVI is theoretically single voltage plane ? ).

After this patch, tilapia can run in higher memory frequency.

2010-11-13MTRR related improvements for AMD family 10h and family 0Fh systemsScott Duplichan
-- When building for UMA, reduce the limit for DRAM below 4GB from E0000000 to C0000000. This is needed to accomodate the UMA frame buffer. -- Correct problem where msr C0010010 bits 21 and 22 (MtrrTom2En and Tom2ForceMemTypeWB) are not set consistently across cores. -- Enable TOM2 only if DRAM is present above 4GB. -- Use AMD Tom2ForceMemTypeWB feature to avoid the need for variable MTRR ranges above 4GB. -- Add above4gb flag argument to function x86_setup_var_mtrrs. Clearing this flag causes x86_setup_var_mtrrs() to omit MTRR ranges for DRAM above 4GB. AMD systems use this option to conserve MTRRs. -- Northbridge.c change to deduct UMA memory from DRAM size reported by ram_resource. This corrects a problem where mtrr.c generates an unexpected variable MTRR range. -- Correct problem causing build failure when CONFIG_GFXUMA=1 and CONFIG_VAR_MTRR_HOLE=0. -- Reserve the UMA DRAM range for AMD K8 as is already done for AMD family 10h. Tested with mahogany on ECS A780G-GM with 2GB and 4GB. Tested with mahogany_fam10 on ECS A780G-GM with 2GB and 4GB.
