acpi: Support checking checksums

2025-04-03T17:43:22+00:00

When the ACPI tables come from an earlier bootloader it is helpful to
see whether the checksums are correct or not. Add a -c flag to the
'acpi list' command to support that.

Add a condition for sandbox, to match that of x86, to avoid the warning
"FADT not ACPI-hardware-reduced-compliant".

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

acpi: rename aslc_id, aslc_revision

2024-03-27T08:15:39+00:00

The fields Creator ID and Creator Revision contain information about the
tool that created an ACPI table. This may be the ASL compiler for some
tables but it is not for others. Naming these fields aslc_id and
aslc_revision is misleading.

It is usual to see diverse values of Creator ID. On a laptop I saw these:
'AMD ', 'INTL, 'MSFT', 'PTEC'. Obviously not all relate to the Intel
ASL compiler.

cmd: acpi: check HW reduced flag in acpi list

2024-01-07T20:49:02+00:00

On non x86 platforms the hardware reduce flag must be set in the FADT
table. Write an error message if the flag is missing.

acpi: Write pointers to tables instead of addresses

2024-01-07T20:45:07+00:00

Sandbox uses an API to map between addresses and pointers. This allows
it to have (emulated) memory at zero and avoid arch-specific addressing
details. It also allows memory-mapped peripherals to work.

As an example, on many machines sandbox maps address 100 to pointer
value 10000000.

However this is not correct for ACPI, if sandbox starts another program
(e.g EFI app) and passes it the tables. That app has no knowledge of
sandbox's address mapping. So to make this work we want to store
10000000 as the value in the table.

Add two new 'nomap' functions which clearly make this exeption to how
sandbox works.

This should allow EFI apps to access ACPI tables with sandbox, e.g. for
testing purposes.

cmd: check argc for acpi dump

'acpi dump' without parameter results in a NULL dereference. Check the
number of arguments.
