2011-07-22Add SSE3 dependent codeefdesign98
This change separates out changes that were initially found in the commit for XHCI and AHCI changes to "arch/x86/Makefile. inc". It also corrects a comment. The SSE3 dependent code adds a pair of CR4 access functions and a blob of code that re-sets CR4.OSFXSR and CR4.OSXMMEXCPT.

2011-07-22Update AMD SR5650 and SB700efdesign98
This updates the code for the AMD SR5650 and SB700 southbridges. Among other things, it changes the romstage.c files by replacing a .C file include with a pair of .H file includes. The .C file is now added to the romstage in the SB700 or SR5650 Makefile.inc. file to the romstage and ramstage elements. This particular change affects all mainboards that use the SB700, and their changes are include herein. These mainboards are: Advansus a785e, AMD Mahogany, Mahogany-fam10, Tilapia-fam10, Asrock 939a785gmh, Asus m4a78-em, m4a785-m, Gigabyte ma785gm, Iei Kino-780am2-fam10 Jetway pa78vm5 Supermicro h8scm_fam10 The nuvoton/wpcm450 earlysetup interface is changed because the file is no longer included in the mainboard romstage.c files.

2011-07-13Make AMD SMM SMP awareRudolf Marek
Move the SMM MSR init to a code run per CPU. Introduce global SMM_BASE define, later all 0xa0000 could be changed to use it. Remove the unnecessary test if the smm_init routine is called once (it is called by BSP only) and also remove if lock bit is set becuase this bit is cleared by INIT it seems. Add the defines for fam10h and famfh to respective files, we do not have any shared AMD MSR header file. Tested on M2V-MX SE with dualcore CPU.

2011-06-18SMM: flush caches after disabling cachingSven Schnelle
Fixes spurious SMI crashes i've seen, and ACPI/SMM interaction. For reference, the mail i've sent to ML with the bugreport: whenever i've docked/undocked the thinkpad from the docking station, i had to do that twice to get the action actually to happen. First i thought that would be some error in the ACPI code. Here's a short explanation how docking/undocking works: 1) ACPI EC Event 0x37 Handler is executed (EC sends event 0x37 on dock) 2) _Q37 does a Trap(SMI_DOCK_CONNECT). Trap is declared as follows: a) Store(Arg0, SMIF) // SMIF is in the GNVS Memory Range b) Store(0, 0x808) // Generates I/O Trap to SMM c) // SMM is executed d) Return (SMIF) // Return Result in SMIF I've verified that a) is really executed with ACPI debugging in the Linux Kernel. It writes the correct value to GNVS Memory. After that, i've logged the SMIF value in SMM, which contains some random (or former) value of SMIF. So i've added the GNVS area to /proc/mtrr which made things work. I've also tried a wbinvd() in SMM code, with the same result. After reading the src/cpu/x86/smm/smmhandler.S code, i've recognized that it starts with: movw $(smm_gdtptr16 - smm_handler_start + SMM_HANDLER_OFFSET), %bx data32 lgdt %cs:(%bx) movl %cr0, %eax andl $0x7FFAFFD1, %eax /* PG,AM,WP,NE,TS,EM,MP = 0 */ orl $0x60000001, %eax /* CD, NW, PE = 1 */ movl %eax, %cr0 /* Enable protected mode */ data32 ljmp $0x08, $1f ...which disables caching in SMM code, but doesn't flush the cache. So the problem is: - the linux axpi write to the SMIF GNVS Area will be written to Cache, because GNVS is WB - the SMM code runs with cache disabled, and fetches SMIF directly from Memory, which is some other value Possible Solutions: - enable cache in SMM (yeah, cache poisoning...) - flush caches in SMM (really expensive) - mark GNVS as UC in Memory Map (will only work if OS really marks that Area as UC. Checked various vendor BIOSes, none of them are marking NVS as UC. So this seems rather uncommon.) - flush only the cache line which contains GNVS. Would fix this particular problem, but users/developers could see other Bugs like this. And not everyone likes to debug such problems. So i won't like this solution.

Overwriting the SMM Area on resume leaves us with all variables cleared out, i.e., the GNVS pointer is no longer available, which makes SMIF function calls impossible.

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 ? ).

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. I didn't understand quite why it did that iwth F3xA0 (Power Control Misc Register) so I moved Pll Lock time to rules in defaults.h and reimplemented F3xA0 programming. A later patch will remove a part I don't know what's mean to do.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Bring F3xD4 (Clock/Power Control Register 0) more in line with BKDG i more cases. It requires looking at the CPU package type so I add a function for that (in the wrong place?) and some new constants Signed-off-by: Xavi Drudis Ferran <xdrudis@tinet.cat> Acked-by: Marc Jones <marcj303@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6395 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode). No change of behaviour intended. Refactor FAM10 fidvid . Factor out the decision whether to update northbridge frequency and voltage because there was the same code in 3 places and so we can later modify it in one place.

Also, our earlier config_clk_power_ctrl_reg0 was still too long and it'd get longer with forthcoming patches. We now take apart F3xD4[PowerStepUp,PowerStepDown] to its own function.
