* OvmfPkg: AcpiPlatformDxe: Don't enable unsupported PCI attributesVolker Rümelin2016-04-191-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code in PciEnableDecoding tries to unconditionally enable EFI_PCI_IO_ATTRIBUTE_IO and EFI_PCI_IO_ATTRIBUTE_MEMORY even if they are unsupported attributes. This fails on devices which don't support both attributes. This patch masks out unsupported attributes. Information to reproduce the bug.

* OvmfPkg: AcpiPlatformDxe: enable PCI IO and MMIO while fetching QEMU tablesLaszlo Ersek2016-03-235-0/+212
| | | | | | | | | | | | | | | | | | | | | Now that the previous patches ensure that we can access all PCI devices in AcpiPlatformDxe, we can enable IO and MMIO decoding for all of them while we contact QEMU for the ACPI tables.

* OvmfPkg: AcpiPlatformDxe: when PCI is enabled, wait for Platform BDS's cueLaszlo Ersek2016-03-233-36/+18
| | | | | | | | | | | | | | | | | | | | | | | | This patch doesn't change the behavior of AcpiPlatformDxe when PcdPciDisableBusEnumeration is TRUE -- that is, when the driver runs on Xen (OvmfPkg and ArmVirtPkg both), or when the driver runs on QEMU as part of ArmVirtPkg but no PCI host bridge was found by VirtFdtDxe. In these cases the driver continues to install the ACPI tables immediately. However, when PcdPciDisableBusEnumeration is FALSE (i.e., when the driver runs on QEMU as part of OVMF, or as part of ArmVirtPkg and VirtFdtDxe finds a PCI host bridge), we now delay the ACPI table download from QEMU. We wait until the Platform BDS tells us that root bridges have been connected, and PciIo instances are available.

* OvmfPkg: AcpiPlatformDxe: make dependency on PCI enumeration dynamicLaszlo Ersek2015-02-193-6/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SVN r16411 delayed ACPI table installation until PCI enumeration was complete, because on QEMU the ACPI-related fw_cfg files should have been downloaded only after PCI enumeration. Said commit implemented the dependency by tightening the module's depex. This patch replaces the EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL depex with a matching protocol registration callback. The depex was static, and it could not handle dynamically discovered situations when the dependency would turn out invalid. Namely: - At the moment, the depex in "QemuFwCfgAcpiPlatformDxe.inf" assumes that "ArmPlatformPkg/ArmVirtualizationPkg/ArmVirtualizationQemu.dsc" lacks PCI support. However, PCI support is about to become run-time discoverable on that platform. If PCI support is missing, then ArmVirtualizationPkg will set PcdPciDisableBusEnumeration to TRUE. Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the dependency by not registering the callback and installing the ACPI tables right away. - InitializeXen() in "OvmfPkg/PlatformPei/Xen.c" sets PcdPciDisableBusEnumeration to TRUE. This causes PciBusDriverBindingStart() in "MdeModulePkg/Bus/Pci/PciBusDxe/PciBus.c" to set gFullEnumeration to FALSE, which in turn makes PciEnumerator() in "MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumerator.c" branch to PciEnumeratorLight(). The installation of EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL at the end of PciEnumerator() is not reached. Which means that starting with SVN r16411, AcpiPlatformDxe is never dispatched on Xen. Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the dependency by not registering the callback and installing the ACPI tables right away.

* OvmfPkg: AcpiPlatformDxe: extract common entry pointLaszlo Ersek2015-02-197-52/+99
| | | | | | | | | | | | | | | | | | | | | | | | Currently the entry point functions of both driver builds (AcpiPlatformDxe.inf and QemuFwCfgAcpiPlatformDxe.inf) directly contain the logic that is different between the two builds. Because we're going to restructure the entry point logic soon, we'd have to duplicate the same new code between both entry point functions. Push down the logic in which they differ to a new function: - InstallAcpiTables() [AcpiPlatform.c] - InstallAcpiTables() [QemuFwCfgAcpiPlatform.c] and extract a common entry point function: - AcpiPlatformEntryPoint() [EntryPoint.c] which we can soon modify without code duplication.

* OvmfPkg: AcpiPlatformDxe: make dependency on PCI enumeration explicitLaszlo Ersek2014-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ACPI payload that OVMF downloads from QEMU via fw_cfg depends on the PCI enumaration and resource assignment performed by MdeModulePkg/Bus/Pci/PciBusDxe. Namely, although the ACPI payload is pre-generated in qemu during machine initialization, in main() [vl.c] qemu_run_machine_init_done_notifiers() pc_guest_info_machine_done() [hw/i386/pc.c] acpi_setup() [hw/i386/acpi-build.c] acpi_build() acpi_add_rom_blob() rom_add_blob(... acpi_build_update ...) [hw/core/loader.c] fw_cfg_add_file_callback() [hw/nvram/fw_cfg.c] the ACPI data is rebuilt at the first time any of the related fw_cfg files are read, through the acpi_build_update() fw_cfg read-callback function: fw_cfg_read() [hw/nvram/fw_cfg.c] acpi_build_update() [hw/i386/acpi-build.c] acpi_build() (See qemu commit d87072ceeccf4f84a64d4bc59124bcd64286c070 and its containing series.) For this reason we must not dispatch AcpiPlatformDxe before PciBusDxe completes the enumeration. Luckily, the PI Specification 1.3 defines EFI_PCI_ENUMERATION_COMPLETE_GUID in Volume 5, "10.9 End of PCI Enumeration Overview", as an indicia to inform the platform when the PCI enumeration process has completed. PciBusDxe installs this protocol at the end of the PciEnumerator() function. Let's add this GUID to the Depex section of AcpiPlatformDxe, in order to state the dependency explicitly. On Xen, and on older QEMU where the linker/loader fw_cfg interface is unavailable, this introduces a harmless ordering constraint -- we'll always include PciBusDxe in OVMF, so the dependency will always be satisfied. I tested this change as follows: - I dumped the ACPI tables in a Fedora 20 guest, before and after the change, and compared them. The only thing that actually changed was the FACS address. (Which I promptly tested with S3 suspend/resume.) Plus, of course, the FACP checksum changed, because the FACP links the FACS. - Tested S3 in my Windows Server 2008 R2 and Windows Server 2012 R2 guests.

* OvmfPkg: AcpiPlatformDxe: implement QEMU's full ACPI table loader interfaceLaszlo Ersek2014-09-222-4/+636
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes in the QEMU ACPI table generator have shown that our limited client for that interface is insufficient and/or brittle. Implement the full interface utilizing OrderedCollectionLib for addressing fw_cfg blobs by name. In order to stay compatible with EFI_ACPI_TABLE_PROTOCOL, we don't try to identify QEMU's RSD PTR and link it into the UEFI system configuration table. Instead, once all linker/loader commands have been processed, we process the AddPointer commands for a second time. In the second pass, we look at the targets of these pointer commands. The key idea (by Michael Tsirkin) is that any ACPI interpreter will only be able to locate ACPI tables by following absolute pointers, hence QEMU's set of AddPointer commands will cover all of the ACPI tables (and more, see below). Some of QEMU's AddPointer commands (ie. some fields in ACPI tables) may point to areas in fw_cfg blobs that are not ACPI tables themselves. Examples are the BGRT.ImageAddress field, and the TCPA.LASA field. We tell these apart from ACPI tables by performing the following checks on pointer target "candidates": - length check against minimum ACPI table size, and remaining blob size - checksum verification. If a target area looks like an ACPI table, and is different from RSDT and DSDT (which EFI_ACPI_TABLE_PROTOCOL handles internally), we install the table (at which point EFI_ACPI_TABLE_PROTOCOL creates a deep copy of the relevant segment of the pointed-to fw_cfg blob). Simultaneously, we keep account if each fw_cfg blob has ever been referenced as the target of an AddPointer command without that AddPointer command actually identifying an ACPI table. In this case the containing fw_cfg file (of AcpiNVS memory type) must remain around forever, because we never install that area with EFI_ACPI_TABLE_PROTOCOL, but some field in some ACPI table that we *do* install still references it, by the absolute address that we've established during the first pass.

| | | | | | | | | | | | | | | | | | | | | | In the next patch we rewrite the client code for QEMU's fw_cfg ACPI table loader interface. In order to avoid randomly intermixed hunks in that patch, first remove the old code cleanly. We remove the InstallQemuLinkedTables() function and empty the InstallAllQemuLinkedTables() function. We also remove CheckRsdp(). InstallAllQemuLinkedTables() will return constant EFI_NOT_FOUND to AcpiPlatformEntryPoint(), causing the latter to proceed to OVMF's builtin tables. This way the history remains bisectable and the new client gets a clean start in the next patch.

* OvmfPkg: AcpiPlatformDxe: download ACPI tables from QEMULaszlo Ersek2014-03-313-7/+163

See version compatibility information below. The feature moves the burden of keeping ACPI tables up-to-date from boot firmware to qemu (which is the source of hardware configuration anyway). This patch adds client code for this feature. Benefits of the qemu-provided ACPI tables include PCI hotplug for example. Qemu provides the following three fw_cfg files: - etc/acpi/rsdp - etc/acpi/tables - etc/table-loader "etc/acpi/rsdp" and "etc/acpi/tables" are similar, they are only kept separate because they have different allocation requirements in SeaBIOS. Both of these fw_cfg files contain preformatted ACPI payload. "etc/acpi/rsdp" contains only the RSDP table, while "etc/acpi/tables" contains all other tables, concatenated. The tables in these two fw_cfg files are filled in by qemu, but two kinds of fields are left incomplete in each table: pointers to other tables, and checksums (which depend on the pointers). Qemu initializes each pointer with a relative offset into the fw_cfg file that contains the pointed-to ACPI table. The final pointer values depend on where the fw_cfg files, holding the pointed-to ACPI tables, will be placed in memory by the guest. That is, the pointer fields need to be "relocated" (incremented) by the base addresses of where "/etc/acpi/rsdp" and "/etc/acpi/tables" will be placed in guest memory. This is where the third file, "/etc/table-loader" comes in the picture. It is a linker/loader script that has several command types: One command type instructs the guest to download the other two files. Another command type instructs the guest to increment ("absolutize") a pointer field (having a relative initial value) in the pointing ACPI table, present in some fw_cfg file, with the dynamic base address of the same (or another) fw_cfg file, holding the pointed-to ACPI table. The third command type instructs the guest to compute checksums over ranges and to store them. In edk2, EFI_ACPI_TABLE_PROTOCOL knows about table relationships -- it handles linkage automatically when a table is installed. The protocol takes care of checksumming too. RSDP is installed automatically. Hence we only need to care about the "etc/acpi/tables" fw_cfg file, determining the boundaries of each ACPI table inside it, and installing those tables.

This will allow a new runtime services firmware block driver to read & write flash memory when the OS has set up virtual memory protection. Since this memory range will appear as runtime services data, we need to adjust the limit when scanning for PCI window 32 down to just below the flash device. If we don't adjust the limit, then the algorithm in PopulateFwData will fail because it will see a EfiGcdMemoryTypeSystemMemory memory range just below 4GB. v2: * This patch replaces the v1 patch: "OvmfPkg/AcpiPlatformDxe/Qemu: Allow high runtime memory regions" Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@14837 6f19259b-4bc3-4df7-8a09-765794883524

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.
