| * i386/acpi-build: fix PXB workarounds for unsupported BIOSesLaszlo Ersek2015-06-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch apci: fix PXB behaviour if used with unsupported BIOS uses the following condition to see if a "PXB mem/IO chunk" has *not* been configured by the BIOS: (!range_base || range_base > range_limit) When this condition evaluates to true, said patch *omits* the corresponding entry from the _CRS. Later on the patch checks for the opposite condition (with the intent of *adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been configured). Unfortunately, the condition was negated incorrectly: only the first ! operator was removed, which led to the nonsensical expression (range_base || range_base > range_limit) leading to bogus entries in the _CRS, and causing BSOD in Windows Server 2012 R2 when it runs on OVMF. The correct negative of the condition seen at the top is (range_base && range_base <= range_limit) Fix the expressions. Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

| * i386/acpi-build: more traditional _UID and _HID for PXB root busesLaszlo Ersek2015-06-111-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ACPI specification permits the _HID and _UID objects to evaluate to strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in the ACPI v6.0 spec.) With regard to related standards, the UEFI specification can also express a device address composed from string _HID and _UID identifiers, inside the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table 49, in the UEFI v2.5 spec.) However, numeric (integer) contents for both _HID and _UID are more traditional. They are recommended by the UEFI spec for size reasons: [...] the ACPI Device Path node is smaller and should be used if possible to reduce the size of device paths that may potentially be stored in nonvolatile storage [...] External tools support them better (for example the --acpi_hid and --acpi_uid options of "efibootmgr" only take numeric identifiers). Finally, numeric _HID and _UID contents are existing practice in the QEMU source. This patch was tested with a Fedora 20 LiveCD and a preexistent Windows Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we get, in the SSDT: > Scope (\_SB) > { > Device (PC04) > { > Name (_UID, 0x04) // _UID: Unique ID > Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.
