That worked out much better :)
I see these changes in e820 table, the first part is probably unrelated:
BIOS-e820: [mem 0x0000000000000000-0x000000000009bbff] usable ... BIOS-e820: [mem 0x0000000000100000-0x00000000ba294fff] usable
modified: [mem 0x0000000000000000-0x0000000000000fff] reserved modified: [mem 0x0000000000001000-0x000000000009bbff] usable modified: [mem 0x0000000000100000-0x00000000ba27bfff] usable ... modified: [mem 0x00000000ba27c000-0x00000000ba2947fc] ACPI data modified: [mem 0x00000000ba2947fd-0x00000000ba294fff] usable
And the ACPI data section where the modified tables are placed seem to get correctly inserted at: 0x00000000ba27c000-0x00000000ba2947fc
-> 0x187FC == 100,348 bytes DSDT and FACP (better known as FADT) I passed have a size of (see dmesg parts below): 0x18709 + 0xF4 bytes = 100,349 bytes.
Ah wait the 0xba2947fc is inclusive, so it should exactly fit.
I then see: DSDT ACPI table found in initrd [0x378f5208-0x3790d910] FACP ACPI table found in initrd [0x3790d9a0-0x3790da93] ACPI: RSDP 00000000000f0410 00024 (v02 INTEL) ACPI: XSDT 00000000bdf24d98 0008C (v01 INTEL ROMLEY 06222004 INTL 20090903) ACPI: Override [FACP- ROMLEY], this is unsafe: tainting kernel Disabling lock debugging due to kernel taint ACPI: FACP 00000000bdf24a98 Physical table override, new table: ffffffffff4af709 ACPI: FACP 00000000ba294709 000F4 (v04 INTEL ROMLEY 06222004 INTL 20121220) ACPI BIOS Bug: Warning: Invalid length for FADT/Pm1aControlBlock: 32, using default 16 (20130117/tbfadt-649) ACPI: Override [DSDT- ROMLEY], this is unsafe: tainting kernel ACPI: DSDT 00000000bdf09018 Physical table override, new table: ffffffffff4af000 ACPI: DSDT 00000000ba27c000 18709 (v02 INTEL ROMLEY 00000021 INTL 20121220)
Later I see my debug string added to the DSDT when the PCI Routing Table (_PRT) is processed: [ 9.505419] [ACPI Debug] String [0x0A] "XXXXXXXXXX"
And taking the FADT from /sys/firmware/acpi/tables/FACP: my: PM Profile : 04 [Enterprise Server] changed (as expected) to: PM Profile : 02 [Mobile]
From acpi overriding parts: Tested-by: Thomas Renninger <trenn@suse.de>
I also went through the override related patches and from what I can judge (certainly not the early memory, flat 32 bit memory you call it? specific parts), they look fine.
Nice work!
Thomas
