2011-06-28Addition of Family12/SB900 wrapper codeefdesign98
This change adds the wrapper code for the AMD Family12 cpus and the AMD Hudson-2 (SB900) southbridge to the cpu, northbridge and southbridge folders respectively.

This change renames the cpu/amd/agesa_wrapper, northbridge/ amd/agesa_wrapper, and southbridge/amd/cimx_wrapper folders to {cpu|NB}/amd/agesa and {SB}/amd/agesa to shorten and simplify the folder names. There is also a fix to vendorcode/amd/agesa/lib/amdlib.c to append "ull" to a trio of 64-bit hexadecimal constants to allow abuild to run successfully.

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.

2011-06-15SMM: don't overwrite SMM memory on resumeSven Schnelle
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). No change of behaviour intended. Refactor FAM10 fidvid . prep_fid_change was already long and it'd get longer with forthcoming patches. We now take apart F3xDC[NbsynPtrAdj], Northbridge/core synchronization FIFO pointer adjust, to its own function.

2011-02-26It adds support for automatic PSS object generation for AMD pre fam Fh CPU. ↵Rudolf Marek
Those CPUs require a hardcoded table, which I managed to rewrite during one particularly boring flight. Too pity it is only for Opteron CPUs. Someone needs to finish the second PDF for All others Athlons and Semprons. Also it enables the FID/VID changes in SB. Jakllsch had some troubles with that too but on am2 CPU. Those bits are only documented in SB600. They arent in RRG RPR and BDG.

2011-02-24Add compile-time defaults to some K8 CMOS options in case they're absent in CMOSJosef Kellermann
This affects the CMOS options iommu, ECC_memory, max_mem_clock, hw_scrubber, interleave_chip_selects. If they're absent in cmos.layout, a Kconfig value is used if it exists, or a hardcoded default otherwise. [Patrick: I changed the ramstage CMOS handling a bit, and dropped the reliance of hw_scrubber on ECC RAM, as it has nothing to do with it - it's the cache that's being scrubbed here.] Signed-off-by: Josef Kellermann <seppk@arcor.de> Acked-by: Patrick Georgi <patrick.georgi@secunet.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6380 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
