-2.4.2.6 Requirements for p-states
-
-1.- F3x[84:80] According to table 100 : prep_fid_change
-
-2.- COF/VID :
- 2.4.2.9.1 Steps 1,3-6 and warning for 2,7 if they apply
- fixPsNbVidBeforeWR(...)
- 2.4.2.9.1 Step 8 enable_fid_change
- We do this for all nodes, I don't understand BKDG 100% on
- whether this is or isn't meant by "on the local
- processor". Must be OK.
- 2.4.2.9.1 Steps 9-10 (repeat 1-7 and reset) romstage.c/init_cpus ?
- 2.4.2.9.1 Steps 11-12 init_fidvid_stage2
- 2.4.2.9.2 DualPlane PVI : Not supported, don't know how to detect,
- needs specific circuitry.
-
-3.- 2.4.2.7 dualPlaneOnly(dev)
-
-4.- 2.4.2.8 applyBoostFIDOffset(dev, nodeid)
-
-5.- enableNbPState1(dev)
-
-6.- 2.4.1.7
- a) UpdateSinglePlaneNbVid()
- b) setVSRamp(), called from prep_fid_change
- c) prep_fid_change
- d) improperly, for lack of voltage regulator details?,
- F3xA0[PsiVidEn] in defaults.h
- F3xA0[PsiVid] in init_cpus.c AMD_SetupPSIVID_d (before prep_fid_change)
-
-7.- TODO (Core Performance Boost is only available in revision E cpus, and we
- don't seem to support those yet, at least they don't have any
- constant in amddefs.h )
-
-8.- FIXME ? Transition to min Pstate according to 2.4.2.15.3 is required
- by 2.4.2.6 after warm reset. But 2.4.2.15 states that it is not required
- if the warm reset is issued by coreboot to update NbFid. So it is required
- or not ? How can I tell who issued warm reset ?
- coreboot transitions to P0 instead, which is not recommended, and does
- not follow 2.4.2.15.2 to do so.
-
-9.- TODO Requires information on current delivery capability
- (depends on mainboard and maybe power supply ?). One might use a config
- option with the maximum number of Amperes that the board can deliver to CPU.
-
-10.- [Multiprocessor] TODO 2.4.2.12
- [Uniprocessor] FIXME ? We call setPStateMaxVal() in init_fidvid_stage2,
- but not sure this is what is meant by "Determine the valid set of
- P-states based on enabled P-states indicated
- in MSRC001_00[68:64][PstateEn]" in 2.4.2.6-10
-
-11.- finalPstateChange() from init_fidvid_Stage2 (BKDG says just "may", anyway)
-
-12.- generate ACPI for p-states.
- generated in powernow_acpi.c amd_generate_powernow()
-
-"must also be completed"
-
-a.- PllLockTime set in ruleset in defaults.h
- BKDG says set it "If MSRC001_00[68:64][CpuFid] is different between
- any two enabled P-states", but since it does not say "only if"
- I guess it is safe to do it always.
-
-b.- prep_fid_change(...)
