Originally NVDIMM Label methods was defined in Intel PMEM _DSM Interface
Spec [1], of function index 4, 5 and 6.
Recent ACPI spec [2] has deprecated those _DSM methods with ACPI NVDIMM
Label Methods _LS{I,R,W}. The essence of these functions has no changes.

This patch set is to update QEMU emulation on this, as well as update
bios-table-test golden binaries.

[1] Intel PMEM _DSM Interface Spec v2.0, 3.10 Deprecated Functions
https://pmem.io/documents/IntelOptanePMem_DSM_Interface-V2.0.pdf
[2] ACPI Spec v6.4, 6.5.10 NVDIMM Label Methods
https://uefi.org/sites/default/files/resources/ACPI_Spec_6_4_Jan22.pdf

---
Change Log:
v3 --> v4:
Use more LocalX in ASL functions, instead of global scope variables.

v2 --> v3:
Patch of nvdimm_debug() --> qemu trace, has been separated and already
upstream'ed.
Patch of accepting _DSM rev.2 is dropped, as unnecessary.
Roll back implementation to the idea of simply wrapper _DSM.

v1 --> v2:
Almost rewritten
Separate Patch 2
Dance with tests/qtest/bios-table-tests
Add trace event

Robert Hoo (5):
  tests/acpi: allow SSDT changes
  acpi/ssdt: Fix aml_or() and aml_and() in if clause
  acpi/nvdimm: define macro for NVDIMM Device _DSM
  acpi/nvdimm: Implement ACPI NVDIMM Label Methods
  test/acpi/bios-tables-test: SSDT: update golden master binaries

Hi Igor,

Here is a little different from original proposal 
https://lore.kernel.org/qemu-devel/80b09055416c790922c7c3db60d2ba865792d1b0.camel@linux.intel.com/

   Local1 = Package (0x2) {STTS, toBuffer(LDAT)}

Because in my test, Linux guest complains:

[    3.884656] ACPI Error: AE_SUPPORT, Expressions within package
elements are not supported (20220331/dspkginit-172)
[    3.887104] ACPI Error: Aborting method \_SB.NVDR.NV00._LSR due to
previous error (AE_SUPPORT) (20220331/psparse-531)


So I have to move toBuffer() out of Package{} and name LSA to hold the
buffer. If you have better idea, pls. let me know.

No, Package{} doesn't accept LocalX as elements.

PackageTerm :=
Package (

PackageList :=
Nothing | <PackageElement PackageListTail>

PackageElement :=
DataObject | NameString

updating binaries can be done when applying, this is why
we have the process of splitting these patches out.

If the diff looks good to you - then just ack this, and I will
check it's the diff when applying.
