Author: mjones Date: 2008-04-23 01:32:56 +0200 (Wed, 23 Apr 2008) New Revision: 3252 Removed: trunk/coreboot-v2/src/cpu/amd/model_10xxx/fidvid_common.c trunk/coreboot-v2/src/cpu/amd/model_10xxx/pstate.c Modified: trunk/coreboot-v2/src/cpu/amd/model_10xxx/Config.lb trunk/coreboot-v2/src/cpu/amd/model_10xxx/model_10xxx_init.c Log: Clean up and remove late initialization code that is no longer needed. Pstate intialization has moved to early init because it requires a warm reset. Add CPUID setup and disable SMM access to late initialization. Much of this code is leftover from porting from K8.

-- Marc Jones Senior Firmware Engineer (970) 226-9684 Office mailto:Marc.Jones@amd.com http://www.amd.com/embeddedprocessors Find matching settings for each CPUs FID, VID, and P-state registers and initialize them. Supports single and split plane systems. Set P0 on all cores for best performance. All APs will be in hlt(C1). The platform warm rest logic has been updated to alway reset for HT and FID/VID setup.

Author: mjones Date: 2008-04-23 01:27:53 +0200 (Wed, 23 Apr 2008) New Revision: 3251 Modified: trunk/coreboot-v2/src/cpu/amd/model_10xxx/fidvid.c trunk/coreboot-v2/src/mainboard/amd/serengeti_cheetah_fam10/cache_as_ram_auto.c trunk/coreboot-v2/src/northbridge/amd/amdht/AsPsDefs.h Log: Find matching settings for each CPUs FID, VID, and P-state registers and initialize them. Supports single and split plane systems. Set P0 on all cores for best performance. All APs will be in hlt(C1). The platform warm rest logic has been updated to alway reset for HT and FID/VID setup. It is not optional anymore.

[patch][v2] [1/4] Family 10
by Marc Jones 22 Apr '08

22 Apr '08

This is the first of four Fam10 patches that I have been promising since the coreboot summit. Thanks for being patient. Marc -- Marc Jones Senior Firmware Engineer (970) 226-9684 Office mailto:Marc.Jones@amd.com http://www.amd.com/embeddedprocessors Add early MSR and PCI register initialization. This fixes many default setting as well as erratas. Some CPU core functions were moved from the HT init and platform specific code to the generic Fam10 CPU code.

Author: mjones Date: 2008-04-23 01:09:34 +0200 (Wed, 23 Apr 2008) New Revision: 3249 Added: trunk/coreboot-v2/src/cpu/amd/model_10xxx/defaults.h Log: Missed this file in the previous check-in, r3248. Add early MSR and PCI register initialization. This fixes many default setting as well as erratas. Some CPU core functions were moved from the HT init and platform specific code to the generic Fam10 CPU code.

Dear coreboot readers! This is the automated build check service of coreboot. The developer "mjones" checked in revision 3248 to the coreboot source repository and caused the following changes: Change Log: Add early MSR and PCI register initialization. This fixes many default setting as well as erratas. Some CPU core functions were moved from the HT init and platform specific code to the generic Fam10 CPU code. Signed-off-by: Marc Jones <marc.jones(a)amd.com> Acked-by: Stefan Reinauer <stepan(a)coresystems.de> Build Log: Compilation of amd:serengeti_cheetah_fam10 has been broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=3248&device=serengeti_chee… If something broke during this checkin please be a pain in mjones's neck until the issue is fixed. If this issue is not fixed within 24h the revision should be backed out. Best regards, coreboot automatic build system
