2012-09-12OvmfPkg: key PMBA setup in Platform PEI off of PMREGMISC/PMIOSE, not Xenjljusten
This matches the logic in AcpiTimerLib. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@13723 6f19259b-4bc3-4df7-8a09-765794883524
2012-09-12OvmfPkg: enable PIIX4 IO space in the PEI phasejljusten
I. There are at least three locations in OvmfPkg that manipulate the PMBA and related PIIX4 registers. 1. MiscInitialization() [OvmfPkg/PlatformPei/Platform.c] module type: PEIM -- Pre-EFI Initialization Module (a) currently sets the PMBA only: 00.01.3 / 0x40 bits [15:6] 2. AcpiTimerLibConstructor() [OvmfPkg/Library/AcpiTimerLib/AcpiTimerLib.c] module type: BASE -- probably callable anywhere after PEI (a) sets the PMBA if needed: 00.01.3 / 0x40 bits [15:6] (b) sets PCICMD/IOSE if needed: 00.01.3 / 0x04 bit 0 (c) sets PMREGMISC/PMIOSE: 00.01.3 / 0x80 bit 0 3. AcpiInitialization() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c] module type: DXE_DRIVER -- Driver eXecution Environment (a) sets SCI_EN, which depends on correct PMBA setting from earlier ( The relative order of #1 and #3 is dictated minimally by their module types. Said relative order can be verified with the boot log: 27 Loading PEIM at 0x00000822320 EntryPoint=0x00000822580 PlatformPei.efi 28 Platform PEIM Loaded 1259 PlatformBdsInit 1270 PlatformBdsPolicyBehavior Line 28 is printed by InitializePlatform() [OvmfPkg/PlatformPei/Platform.c] which is the entry point of that module. The other two lines are printed by the corresponding functions in "OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c". ) Currently #2 (AcpiTimerLibConstructor()) is called in a random spot (whenever it gets loaded from the firmware image) and masks the insufficient setup in #1. We shouldn't depend on that, PEI should finish with IO space being fully accessibe. In addition, PEI should program the same PMBA value as AcpiTimerLib. II. The PEI change notwithstanding, AcpiTimerLib should stay defensive and ensure proper PM configuration for itself (either by confirming or by doing). III. Considering a possible cleanup/unification of #2 and #3: timer functions relying on AcpiTimerLibConstructor(), - MicroSecondDelay() - NanoSecondDelay() - GetPerformanceCounter() - GetPerformanceCounterProperties() - GetTimeInNanoSecond() may be called before #3 is reached (in Boot Device Selection phase), so we should not move the initialization from #2 to #3. (Again, AcpiTimerLib should contain its own setup.) We should also not move #3 to an earlier phase -- SCI_EN is premature unless we're about to boot real soon ("enable generation of SCI upon assertion of PWRBTN_STS, LID_STS, THRM_STS, or GPI_STS bits").
