Current Activities

  • Clean up superio support.
  • Fix DSDT/SSDT in AGESA

AGESA - DSDT/SSDT

Current list of issues below:

Error 6126: syntax error, ***

Notes:

We may extract and decompile the first SSDT table in the following way: 

cat /sys/firmware/acpi/tables/SSDT1 > ssdt.dd ; iasl -d ssdt.dd

A snip of the broken code fragment in question is given: 

If (LEqual (Local2, 0x07))
{
    If (CondRefOf (\_SB.ALIC, Local6))
    {
        Store (ShiftLeft (Add (Arg0, 0x02), 0x03), Local1)
        \_SB.ALIC (Local1, 0x00, Sleep (0x02), \_SB.ALIC (Local1, 0x01, Store (0x00, 
            Local3), Store (0x01, Local2), Continue, Store (0x04, Local2)), If (LEqual (Local2, 
            0x05))
            {
                Store (0x01, Local4)
                Store (0x00, Local2)
                A074 (Arg0, 0x02)
            }, If (LEqual (Local2, 0x00))
            {
                Store (0x01, A017) /* \_SB_.A017 */
                A029 ()
                Store (0x08, Local2)
            })
    }
}


Currently AGESA has pre-compiled a bunch of .esl files into:

src/vendorcode/amd/agesa/f14/Proc/GNB/PCIe/Family/0x14/F14PcieAlibSsdt.h

This array of pre-compiled SSDT bytecode is used to construct the SSDT table in:

src/vendorcode/amd/agesa/f14/Proc/GNB/Modules/GnbPcieAlibV1/PcieAlib.c

in the function: 

AGESA_STATUS PcieAlibBuildAcpiTable ( IN AMD_CONFIG_PARAMS *StdHeader, OUT VOID  **AlibSsdtPtr ) { .. }

The root of SSDT seems to be in the file: vendorcode/amd/agesa/f14/Proc/GNB/PCIe/Family/0x14/F14PcieAlib.esl

We can work around the broken SSDT in mainboard support by maing the following changes to this line in acpi_tables.c: 

- alib = (acpi_header_t *)agesawrapper_getlateinitptr (PICK_ALIB);
+ // alib = (acpi_header_t *)agesawrapper_getlateinitptr (PICK_ALIB);
+ alib = NULL;

A full diagnostic report is given:
