[Qemu-devel] [PULL v2 11/49] tests: acpi: reuse fetch_table() for fetching FACS and DSDT |
Date: |
Tue, 15 Jan 2019 15:04:36 -0500 |
From: Igor Mammedov <address@hidden>
It allows to remove a bit more of code duplication and
reuse common utility to get ACPI tables from guest (modulo RSDP).
While at it, consolidate signature checking into fetch_table() instead
of open-codding it.
Considering FACS is special and doesn't have checksum, make checksum
validation optin, the same goes for signature verification.
PS:
By pure accident, patch also fixes FACS not being tested against
reference table since it wasn't added to data::tables list.
But we managed not to regress it since reference file was added
by commit
(d25979380 acpi unit-test: add test files)
back in 2013
