2013-01-28OvmfPkg: set ActiveHigh polarity for the SCI with a dedicated link devicejljusten
We cannot specify a pin-GSI connection for the SCI directly in the _PRT because that implies ActiveLow polarity, clashing with both qemu and the MADT we prepare. With this patch the RHEL-6 guest logs the following: ACPI: PCI Interrupt Routing Table [\_SB_.PCI0._PRT] ACPI: PCI Interrupt Link [LNKS] (IRQs *9) ACPI: PCI Interrupt Link [LNKA] (IRQs 5 10 *11) ACPI: PCI Interrupt Link [LNKB] (IRQs 5 10 *11) ACPI: PCI Interrupt Link [LNKC] (IRQs 5 *10 11) ACPI: PCI Interrupt Link [LNKD] (IRQs 5 *10 11) The patch amends svn rev 13625. Testing it in a RHEL-6 guest, the problems described in <http://sourceforge.net/mailarchive/message.php?msg_id=29660862> do not reappear. The code is derived from Paolo Bonzini's patch (originally appearing as SeaBIOS commit f64a472a, "acpi: reintroduce LNKS"). Said original patch is copyrighted by Red Hat (our common employer), and it has been relicensed <http://sourceforge.net/mailarchive/message.php?msg_id=30393854> to form the basis of this derived patch for edk2.

2012-12-17OvmfPkg: create \_S3 and \_S4 packages dynamicallyjljusten
Move these states from the DSDT to the SSDT. Override the default configuration if the host has the following qemu commit: commit 459ae5ea5ad682c2b3220beb244d4102c1a4e332 Author: Gleb Natapov <gleb@redhat.com> Date: Mon Jun 4 14:31:55 2012 +0300 Add PIIX4 properties to control PM system states. This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.

2012-12-17OvmfPkg: report S3 state in DSDTjljusten
The ACPI 5.0 specification says: 7.3.4.4 System \_S3 State [...] * Dynamic RAM context is maintained. [...] This corresponds to the following in the PIIX4 spec: PMCNTRL -- POWER MANAGEMENT CONTROL REGISTER (IO) [...] Bits[12:10] Suspend Type [...] 001 STR (Suspend To RAM) Also, this (ie. decimal 1) is the suspend type value that qemu recognizes as an S3 (suspend to ram) request. Only the value for PM1a_CNT.SLP_TYP is set (PM1b_CNT.SLP_TYP is left at zero), since in OVMF we don't report the optional PM1b_EVT_BLK register block to OSPM. (PM1b_EVT_BLK is defined as 0 in "Platform.h"; see "4.8.1.1 PM1 Event Registers" in the ACPI 5.0 specification.)

2012-08-13OvmfPkg: _DIS and _SRS methods should have permanent effectjljusten
Kill PDIS and PSRS as they are writing to copies of PIR[A-D], not PIR[A-D] themselves. Use specialized _DIS and _SRS methods that access PIR[A-D] directly. (This should be solvable by passing RefOf (PIRA) etc to PDIS/PSRS, however the RHEL-6.3 kernel AML parser seems to choke on it. The rules described in ACPIspec5.0 Table 19-316 "Object Storing and Copying Rules" don't seem to work: ACPI Error: Needed [Integer/String/Buffer], found [Reference] ffff88003ee02420 (20090903/exresop-422) ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20090903/dswexec-445) ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.PDIS] (Node ffff88003f638b50), AE_AML_OPERAND_TYPE ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.LNKA._DIS] (Node ffff88003f638a10), AE_AML_OPERAND_TYPE When changing the method too, so that it writes to DerefOf (Arg0) instead of Arg0, ie. explicitly dereferencing rather than expecting the auto-deref to work: ACPI Error: Needed type [Reference], found [RegionField] ffff88003f639858 (20090903/exresop-104) ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20090903/dswexec-445) ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.PDIS] (Node ffff88003f638b50), AE_AML_OPERAND_TYPE ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.LNKA._DIS] (Node ffff88003f638a10), AE_AML_OPERAND_TYPE In short, when passing a RefOf, it is recognized as a reference inside the method but mistakenly refused.
