* OvmfPkg: Update DxeAcpiTimerLib to read HostBridgeDevId in PlatformInfoHobMin Xu2022-04-022-6/+26
| | | | | | | | | | | | | | | | | | | | | | | | | RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 The entrypoint of DxeAcpiTimerLib checks HostBridgeDevId by reading PcdOvmfHostBridgePciDevId. If the DevId is not set, ASSERT is triggered. Normally this DevId is set in PlatformPei which is executed in PEI phase. This patch-set is introducing PEI-less boot which means PEI phase is skipped. So there is no chance to set this DevId. Instead HostBridgeDevId is set in PlatformInfoHob. So we can check if PlatformInfoHob exists and if HostBridgeDevId is set in this Hob.

* OvmfPkg: determine PMBA value dependent on host bridge device IDLaszlo Ersek2016-05-172-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | In this patch, the AcpiTimerLib instances, ResetSystemLib, and PlatformPei are modified together in order to keep VMs functional across a bisection: they all must agree on the PMBA value used. ResetSystemLib must not use dynamic PCDs. With SOURCE_DEBUG_ENABLE, it gets linked into the debug agent, therefore the same restrictions apply to it as to BaseRomAcpiTimerLib. Luckily, AcpiPmControl() is only used for powering off the virtual machine, thus the extra cost of a PCI config space read, compared to a PcdGet16(), should be negligible. This is the patch that moves the PMBA to IO port 0x0600 on Q35 in practice. The ResetSystemLib change is easiest to verify with the "reset -s" command in the UEFI shell (which goes through gRT->ResetSystem() and, in OVMF, PcAtChipsetPkg/KbcResetDxe).

| | | | | | | | | | | | | | | | | | | | | In the next patches, we'll differentiate the PMBA IO port address that we program on PIIX4 vs. Q35. Normally we'd just turn PcdAcpiPmBaseAddress into a dynamic PCD. However, because we need this value in BaseRomAcpiTimerLib too (which cannot access RAM and dynamic PCDs), it must remain a build time constant. We will introduce its Q35 counterpart later. As first step, replace the PCD with a new macro in "OvmfPlatforms.h"; Jordan prefers the latter to fixed PCDs in this instance.

* OvmfPkg: Q35: Use correct ACPI PM control register:bitGabriel Somlo2015-03-262-20/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On PIIX4, function 3, the PMREGMISC register at offset 0x80, with default value 0x00 has its bit 0 (PMIOSE) indicate whether the PM IO space given in the PMBA register (offset 0x40) is enabled. PMBA must be configured *before* setting this bit. On Q35/ICH9+, function 0x1f, the equivalent role is fulfilled by bit 7 (ACPI_EN) in the ACPI Control Register (ACPI_CNTL) at offset 0x44, also with a default value of 0x00. Currently, OVMF hangs when Q35 reboots, because while PMBA is reset by QEMU, the register at offset 0x80 (matching PMREGMISC on PIIX4) is not reset, since it has a completely different meaning on LPC. As such, the power management initialization logic in OVMF finds the "PMIOSE" bit enabled after a reboot and decides to skip setting PMBA. This causes the ACPI timer tick routine to read a constant value from the wrong register, which in turn causes the ACPI delay loop to hang indefinitely. This patch modifies the Base[Rom]AcpiTimerLib constructors and the PlatformPei ACPI PM init routines to use ACPI_CNTL:ACPI_EN instead of PMREGMISC:PMIOSE when running on Q35.

* OvmfPkg: AcpiTimerLib: Split into multiple phase-specific instancesGabriel Somlo2014-11-149-189/+474
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove local power management register access macros in favor of factored-out ones in OvmfPkg/Include/OvmfPlatforms.h Next, AcpiTimerLib is split out into three instances, for use during various stages: - BaseRom: used during SEC, PEI_CORE, and PEIM; - Dxe: used during DXE_DRIVER and DXE_RUNTIME_DRIVER; - Base: used by default during all other stages. Most of the code remains in AcpiTimerLib.c, to be shared by all instances. The two platform-dependent methods (constructor and InternalAcpiGetTimerTick) are provided separately by source files specific to each instance, namely [BaseRom|Base|Dxe]AcpiTimerLib.c. Since pre-DXE stages can't rely on storing data in global variables, methods specific to the "BaseRom" instance will call platform detection macros each time they're invoked. The "Base" instance calls platform detection macros only from its constructor, and caches the address required by InternalAcpiTimerTick in a global variable. The "Dxe" instance is very similar to "Base", except no platform detection macros are called at all; instead, the platform type is read via a dynamic PCD set from PlatformPei.

This patch removes the mPmba global variable and instead reads the PIIX4 Power Management Base Address from PCI configuration space when it is needed. This patch also simplifies the initialization logic in the constructor and introduces #defines to eliminate hard coded values in the function implementations. According to the PIIX4 documentation, the IO Space enable bit in the PCI Command Register does not have to be set for the Power Management Base Address to be decoded, so that one op has been removed from the constructor.
