XPress-RICH3 PCIe driver initializes the root complex with the source and target address for IO window. The root complex resources in SSDT should match these settings.

It also adds 'TypeTranslation' to the IO window Contributed-under: TianoCore Contribution Agreement 1.0 Cc: Ard Biesheuvel <[email protected]> Cc: Leif Lindholm <[email protected]> Cc: Tomasz Nowicki <[email protected]> Cc: Graeme Gregory <[email protected]> Signed-off-by: Sudeep Holla <[email protected]> --- Platforms/ARM/Juno/AcpiTables/AcpiSsdtRootPci.asl | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) v3->v4: - Fixed the max to match the length and added TypeTranslation v2->v3: - Fixed $subject and the commit log v1->v2: - Made changes as suggested by Graeme & Tomasz diff --git a/Platforms/ARM/Juno/AcpiTables/AcpiSsdtRootPci.asl b/Platforms/ARM/Juno/AcpiTables/AcpiSsdtRootPci.asl index 800d2cb3b2fb..969c42398f18 100644 --- a/Platforms/ARM/Juno/AcpiTables/AcpiSsdtRootPci.asl +++ b/Platforms/ARM/Juno/AcpiTables/AcpiSsdtRootPci.asl @@ -107,10 +107,11 @@ DefinitionBlock("SsdtPci.aml", "SSDT", 1, "ARMLTD", "ARM-JUNO", EFI_ACPI_ARM_OEM PosDecode, EntireRange, 0x00000000, // Granularity - 0x5f800000, // Min Base Address - 0x5fffffff, // Max Base Address + 0x00000000, // Min Base Address + 0x007fffff, // Max Base Address 0x5f800000, // Translate - 0x00800000 // Length + 0x00800000, // Length + ,,,TypeTranslation ) }) // Name(RBUF) -- 1.9.1 _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
